Suggested March 2024 Photosweeper Review: Easily Clean Out Duplicate Images On Your Mac

I may have mentioned this before: I take a lot of pictures. If I’m not trying to get the perfect shot of a rock band with my Nikon, I’m snapping pics with my iPhone. I am, by no means, a pro. I’m not even as much of an avid hobbyist as many others would consider themselves to be. I do, however, have a lot of pictures stored on my computer and in iPhoto. Many of them are duplicates of the same subject because I’m always trying to get just the right shot at the right moment.

Many of them are duplicates of the same subject because I’m always trying to get just the right shot at the right moment.

PhotoSweeper is a file cleaner for OS X that will help you clear out duplicate images by finding similar compositions and letting you delete what you don’t want from the original location…

Design

PhotoSweeper has a very similar interface to iPhoto. In fact, I found myself looking for the editing tools so that I could fix the lighting or contrast on images. You can’t do anything like that in PhotoSweeper. All you can do is find photos that look the same and then delete, copy, or move them.

You can add files of pictures from iPhoto, Aperture, and Adobe Lightroom. When you first open the app, it will automatically detect and connect to your photography program. Files will appear in the Media Browser. You can drag individual images or entire files. You could even drag and drop your entire iPhoto photo collection. You can also add photos directly from you computer by dragging and dropping them from a file on your hard drive.

Once added, the images will appear as thumbnails (large sized). You can then hit the Compare button at the bottom to find duplicates. Then, either manually or auto-mark images that you want to delete.  When you are ready, check out all marked photos by selecting “Show Marked” at the bottom of the screen to double check that you are ready to rid your computer of the extras. Then, select the pictures and drop them in the trash by selecting “Move to Trash” at the bottom of the screen.

You can adjust the level at which PhotoSweeper will match duplicates. If you set “Partial Matching,” it will locate images that have similar subject matter. If you select “Exact Matching,” it will locate multiple pictures that you took of a very exact moment.

You can also adjust the algorithm for comparison and grouping, group photos by time intervals between capture dates, select a specific Bitmap size, and determine bitmap creation settings (RBG, blur, color sensitivity, etc.).

App Use

The first thing you will need to do is add images. You can either add them from iPhoto, Aperture, or Adobe Lightroom by selecting the Media Browser icon in the toolbar at the bottom of the screen. This will connect you to your photography application and load images that you can drag into the PhotoSweeper window.

You can also add pictures that are stored in you computer’s hard drive (or an external hard drive) by selecting the Add button from the toolbar. This will open your Mac’s Finder folder. Select the images you wish to compare and drag them to the app.

When you have added all images you wish to search for duplicates for, you can activate the comparison feature. Adding photos can take as little as a few minutes or as much as a few hours, depending on how many you have.

To find duplicates, select the “Compare” button in the toolbar. If you have more than, say 25,000 photos, it might be a good idea to start the process by only searching for identical photos. This will limit the comparison to a smaller number. Then, you can go back and reduce the matching algorithm to more comparison photos later.

The comparison feature can also take a very long time if you have a lot of photos, so be patient. It will be worth it in the end.

When you are ready to view the results, select either Face-to-Face or Group view. Face-to-Face gives you a close up of only two pictures at a time. This is good for comparing images and picking your favorite, or changing which ones you want marked or not.

Group view shows you all like-images in one group. If it is clear which photo you want to save, you can just leave the marked image, or manually mark the one you wish to delete. This is a time saver if you aren’t particular about exact compositions.

You can set the app to auto mark images that should be considered duplicates and deleted. You can change the auto mark preferences with different rules and orders. However, I found that PhotoSweeper almost always marked the image that I would have tossed out myself.

After you’ve confirmed the marked photos and made sure you aren’t deleting anything you may want to keep, select “Show Marked” to see everything that has been marked.

In this section, you can delete images, move and rename them, copy and rename them, and unmark ones that you want to keep. Trashing photos either throws them into the computer’s trashcan or sends them to the photography application’s internal trash folder. To officially delete items, go into your photo application and select “Empty Trash” and then go to your computer’s trashcan and select Empty Trash again to permanently delete photos and free up space on your computer.

The Good

This app works perfectly. I added everything from my iPhoto program and all images from my Photos folder in Finder and managed to free up about 20GB of space, and that was just getting rid of duplicates of images I didn’t want anyway. The only thing I sacrificed was time.

I love how well the algorithm selects which images to keep and which to delete. It detects proper lighting, appropriate facial expressions, clarity, and subject composition. I only changed the results a handful of times in the, more than 9,000 photos that I deleted.

The Bad

I haven’t found anything bad about this app. However, I can only assume that, for users with really large photo files, it might be a very time consuming process to add images and compare them. I don’t think you could blame Photosweeper for this issue, though.

Value

PhotoSweeper costs $9.99. After you have deleted thousands of duplicate images and freed up dozens of gigs of space on your computer, you won’t think this app is expensive. It really is a must-have program for people who take a lot of photos.

Conclusion

This is a fantastic app that works perfectly. I didn’t even realize I had so many duplicates of images. I feel like I’ve just cleaned out my spare room closet and now have tons of room for more stuff. If you tend to take a lot of pictures, especially a lot of the same subject, looking for the perfect shot, you will love PhotoSweeper. After the first time you use it, finding duplicates for new sets of photos that you take will be even easier. This app is available for Mac OS X 10.6.6 or later. Download it from the Mac App Store today.

Related Apps

There is a lite version of Photosweeper that finds exact duplicates instead of also giving you the option of comparing similar photos.

Do you have a lot of duplicate photos stored on your computer. Does PhotoSweeper sound like something you’d use?

Fix Duplicate Icons On Your Windows 7/8/8.1 Taskbar

For many users, it is not clear why this has happened and the number does not change even if one of the icons is removed. Windows appends a (2) when it encounters a duplicate of the same file, but it is not initially clear where the pinned shortcuts on the taskbar are held. Removing the unnecessary numbers is possible, but it means entering a folder that is hidden by default. By entering the direct route to the files, it is not necessary to make these hidden folders visible, but the same result can be achieved quite easily.

1. Open Windows Explorer and select either “Computer” or “This PC,” depending on your version of Windows. Windows 7 uses the term “Computer”, while all versions of Windows 8 change the name to “This PC.” Regardless of operating system, the folder structure beyond this point is the same.

2. Open the Users folder, and then select your own username, as the shortcuts pinned are unique for each person. This ensures you will not be modifying anyone else’s shortcuts.

4. Copy and paste this string of text to immediately follow your username:

AppDataRoamingMicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar

The “AppData” folder is traditionally hidden in Windows. By pasting this text, you will not have to display hidden files and folders.

5. After pressing Enter, the Explorer window will move inside the folder. From here, there will be a list of all pinned shortcuts. Simply find the shortcut with the offending name and change it to suit. When you reach the Taskbar folder, you may find two shortcuts for the same program. Delete one of the two shortcuts and rename the other to make it suit your naming preferences.

Although hardly the most prominent issue you may encounter when using a computer, it can be frustrating when something as routine as a software update may otherwise ruin a carefully organised taskbar. While it should come as no surprise that the shortcuts are held in an Internal user folder, the fact it is an Internet Explorer folder is rather unusual. This guide should at least eliminate one of the more confusing issues to have appeared in recent versions of Windows.

Larq Purevis Bottle Review: Clean You Can Taste

We may earn revenue from the products available on this page and participate in affiliate programs. Learn more ›

My favorite thing to talk about with Uber drivers, my beloved coffee baristas, or anyone who will listen is that fresh, potable water is actually a hot commodity, and the Water War is very much a thing that is here and happening in this world. I pontificate until I’m so parched that I take a sip from a reusable water bottle like the LARQ PureVis, and I feel like I’ve found an oasis in the desert.

Although water covers more than 70 percent of the Earth’s surface, only 3 percent is drinkable fresh water. Even deeper than that, .5 percent of that drinkable fresh water is available, meaning that it’s not locked in a glacier or the atmosphere. And water from public water systems isn’t guaranteed to be completely safe because of old infrastructure (remember the Flint, Michigan, water crisis?). All that combined equals a very cool worldwide phenomenon that deepens my existential crisis about the rad world we live in that no one is acting on to fix (slay!). 

The LARQ PureVis bottle may not help with the existential doom the water wars bring (I have my therapist and a cabinet full of paraphernalia for that), but it does make me feel better that my bad Pennsylvania water is at least bacteria-free. If, like me, you enjoy staying hydrated but don’t love what the park water fountain yields, the LARQ turns any clear water into a smooth, clarified beverage worthy of being bottled.

Overview

LARQ’s PureVis water bottle uses UV-C light to self-clean and get rid of 99 percent of bio-contaminants, according to the company.

Pros

Lightweight

Easy to use

Quick, noticeable change in water taste after use

Cons

MicroUSB charger not exactly future-proof

Expensive

Small and no wide mouth

No water tracking or app connectivity

Verdict: Adventurers, travelers, and regular ole hypochondriacs will be impressed at the quick change in water taste after using the LARQ PureVis bottle.

The build

The LARQ PureVis bottle is made of food-grade 18/8 stainless steel and is double-vacuum insulated, providing up to 24 hours of cold retention and 12 hours of keeping beverages hot. (A non-insulated option is also available.) It comes in two capacities—17 oz. and 25 oz.—and five colors.

I received the larger LARQ bottle in seaside mint for review and was impressed at how light it was. I use two other vacuum-insulated water bottles regularly—the 36 oz. Yeti Rambler bottle and 32 oz. Hydro Flask Wide Mouth Bottle, tied for my favorite insulated water bottle. If you own a Yeti, you know it’s a bit heavy, and Hydro Flask bottles tend to be lighter. The LARQ beats both of them weight-wise at 17 ounces when empty. (The Yeti weighs 1.5 lbs., and the Hydro Flask is just under a pound.) But it’s in the LARQ cap where the magic happens. It houses the UV-C light—which the company calls “PureVis technology” and claims can eliminate 99 percent of bacteria, including E. coli. The cap also houses a button that controls the bottle’s functions, plus a microUSB port for charging.

There are three modes to choose from: a Normal Mode that gives your water one minute of UV-C exposure; an Adventure Mode option, which ups the UV-C light to three minutes when you need more purification (e.g., you’ve run river water through a portable filter and want to make sure it doesn’t make you poop your pants while you’re hiking); and a Travel Lock mode, which disables the self-cleaning mode for travel or storage. Technically, the self-cleaning mode would count as the fourth, but there’s nothing you need to press to set that up: The bottle self-cleans with 10 seconds of UV-C light every two hours, regardless of use.

The setup

Opening the LARQ PureVis packaging feels like you’re opening a new iPhone. You’re greeted by a message that says, “Meet the bottle that cleans itself,” on its bright white, weighty packaging. The quick-start guide has a little home inside the opening flap, with the bottle nestled in its own cardboard cradle on the other side. You’ll find the microUSB cord (more on that later) under the bottle in a cut-out portion, just like how Apple hides its own included accessories.

All you have to do is find a place to plug the microUSB charger (I chose my favorite place to plug chargers into, my Animal Crossing Nintendo Switch dock), plug the cap into the microUSB charger, and run around your house and do some chores until you see a steady green light. Although I don’t mind using a microUSB cord, I’m always surprised to see one on a device in the year of our Lord 2023, when USB-C has taken over. It’s not a con so much as a very interesting tech choice to make nowadays. 

The quick start guide says to unlock the bottle by pressing the button for 5 seconds until the ring light around the cap flashes white, but nothing happened when I did. However, my bottle did start purifying after one press of the proprietary button on the cap. You can wait for the bottle to do its thing or lightly flip it to spread the PureVis light evenly. You have to be careful when filling up the bottle—you have to get the water about an inch below UV-C light, or it will plunge into the water and cause some overflow, which I learned the hard way.

The performance

I was fully expecting the LARQ PureVis bottle to be a gimmick. However, I was blown away by the incredible changes I tasted as I progressed through tap water, tap water run through a Brita filter, and both waters after exposure to the UV-C light in the LARQ. 

First, I tested the tap water directly (yes, I drank raw Pittsburgh water), then I ran that tap water through the LARQ. I noticed that the tap water tasted incredibly chlorinated—which makes sense, considering water treatment plants add chlorine chloramine, or chlorine dioxide, to water as a disinfector. Tap water tastes refreshing when you happen upon a water fountain in the park, beyond thirsty. However, it’s merely tolerable in any other circumstance. This brings us to the tap water post-LARQ—the chlorination felt like a slap on the wrist compared to the sucker punch of sterilization from the tap water.    

Next, I taste-tested my Brita filtered water and the same Brita water post-UV-C light. I took sips from one bottle containing Brita filtered water and then sips from the LARQ bottle to confirm that they indeed tasted different. Brita filtered water was Dasani levels of crisp, while the LARQ bottle was borderline Fiji silkiness.

I felt like Martin Riese, the Water Sommelier on TikTok, trying to qualify the taste, but I also felt like a huge weirdo drinking from two different water bottles with a perplexed look on my face. I’m an easily distracted child who loves a shiny bright thing, so seeing the light on the cap flash and receiving better-tasting water is a better high than completing your Duolingo daily lesson. I’m slightly more prone to use the LARQ water bottle just to get the instant gratification of my water turning into a different thing, like pulling a Shrinky Dink out of the oven. 

Pennsylvania water is gross, and Pittsburgh water, specifically, is not good. The LARQ removed the tap water’s chlorinated taste and improved the Brita’s flavor profile. Overall, it left me genuinely impressed—it felt like I was aerating wine, cycling through swirl-sniff-sip-savor (and all the feels) as I noted how the water tasted before and after exposure to UV-C light. All I need to do is invest in the Brita filters that filter out lead; then I will have everything I need for the squeaky clean water.

So, who should buy the LARQ PureVis bottle?

The LARQ is perfect for those who want to ensure their water is germ-free post-filtration during a hike or even fresh from the tap. But filtering your tap water and then running it through the LARQ bottle is the way to go, in my opinion. 

Some customer-submitted LARQ reviews say that it’s great for people who travel to another country and want to ensure their bottled water is extra clean or want to be sustainable and drink from the tap without the consequences. I couldn’t test either out, so use caution if you purchase the LARQ and test out the (international) waters. 

I wish the LARQ came in a 32-ounce option. Sure, 25 ounces is enough, but I like the comfort of knowing that I won’t drink all my water while I’m out and about and don’t need to worry about finding a new source, whether that be a river or a nice cafe barista who fills it up for me as I wait on the other side of the counter like a Dickensian child waiting for food scraps. 

The LARQ water bottle is expensive at $99-$118 (depending on size and if you decide on snagging the vacuum-insulated bottle). LARQ offering a version with app connectivity would put the bottle on another level, and help further justify that price. Hydration tracking, reminders to drink, being able to locate your bottle if you misplace it (a bonus considering it’s an expensive water bottle), and germ-free water? In my eyes, that would be worth the money, and more. However, the price tag is a drop in the bucket (or, well, bottle) compared to the pricelessness of clean water. If you’re slightly unhappy with the quality of your drinking water, even post-filtration, but not unhappy enough to spend the time and effort installing an under-the-sink filter, consider the LARQ a band-aid for your knee scrape. 

How To Remap Fn Keys On Your Mac

Whether you use a Windows PC or a Mac machine, your keyboard has all the standard functions keys at the top. These keys are assigned with various functions by the operating system of your computer.

Some of the actions these keys perform are things like increasing and decreasing brightness levels, increasing and decreasing volume levels, opening certain functions, and so on. On a Mac machine, these keys trigger some of the macOS’ default actions, such as opening the Mission Control view.

Table of Contents

The issue here is that, while some of these keys are used frequently, others remain unused simply because their functions aren’t as common. The best way to put these unused fn keys on Mac into use is to remap them. 

Remapping keys lets you assign custom functions to the keys. These keys will then perform the actions that you assign to them on your Mac.

Disable The Default Function Keys Behavior

Before you assign any custom actions to your keys, the first thing you’ll want to do is disable the default actions of your keys. This will disable the useful keys as well but you can always use them by pressing and holding down the fn button on your keyboard. It will then make your keys do the action that’s printed on them.

Disabling the function keys is easy on a Mac. Here’s how you do it:

On the following screen, you’ll find a few options that you can enable and disable. Find the option that says Use F1, F2, etc. keys as standard function keys and turn it on.

You’ve successfully turned off the default behavior of your fn keys.

Remap Functions Keys

Now that the default function key actions are turned off, you can go ahead and assign custom actions to these keys. It’s pretty easy to do this and you don’t need a third-party app to do the task.

You’re going to use the same System Preferences pane to get this task done.

You don’t need to save any changes as it’ll be automatically done by macOS.

From now on, whenever you press the fn key specified above on your keyboard, it’ll take a screenshot instead of performing the usual action it does. You can assign any of your function keys to any of the shortcuts you find in there.

Map Functions Keys To Perform Specific Actions

While the built-in Keyboard menu has a lot of keyboard shortcuts for you to use and to assign to the fn keys, it doesn’t have all the shortcuts. There are certain shortcuts that you may want to use by pressing your fn keys but those aren’t listed here.

One of the ways to have your custom shortcuts listed there is to add them to the list. The following shows how it’s done:

Open the app for which you want to create a custom fn key action. As an example, I’ll open Google Chrome to create an fn key shortcut for launching an incognito window.

From now on, when you press the fn key you used above, it’ll perform the action that you just entered in the Menu Title box. In my case, it’ll open a new incognito window in Google Chrome.

Use A Third-Party App To Remap Fn Keys on MacOS

macOS, by default, gives you plenty of options to customize the behavior of your function keys. However, if you want even more power, you may need to use a third-party app.

Karabiner is one of the popular apps that helps you customize how various keyboard shortcuts work on your Mac machine. It lets you create multiple profiles so you can have one set of keyboard shortcuts in one profile and another set in a secondary profile.

There are several other features in the app that you may want to explore.

New Uses For Your Function Keys

If you can’t think of any particular function for your keys, you can assign some of the following functions to your keys. These are used by most Mac users.

Browser new tab

Browser new incognito tab

Screenshots

Do not disturb mode

Close app

Hide and unhide the Dock

Feel free to use your creativity and imagination to make these keys work the way you want.

External Display Issues On Your Mac? Try These Steps

Many people use external displays with their Mac, either to mirror their display to a larger screen or expand their screen area for additional productivity. As good as this sounds, sometimes problems can occur with an external display that will require attention to get fixed.

In this piece, we’ll go over various things that could go wrong with an external display, as well as some potential troubleshooting steps to fix the problem.

What could possibly go wrong with Mac’s external display?

External displays, whether you bought one of Apple’s rather pricey options or you went with a third-party brand like LG, Samsung, or Dell, are subject to potential issues.

Although Apple does its best to make things plug-and-play, other manufacturers tend to have very different standards, and this means you may have to troubleshoot issues or take extra steps to configure a display to work properly with your Mac.

Even if your display isn’t new, you may have nudged a configuration button by mistake, which could cause all kinds of issues with its performance. If it wasn’t you that tapped the button, and it happened while you weren’t even home because one of your kids was toying around, or someone else who used the computer changed the settings, then this makes it even more challenging to figure out what’s going on.

Among some of the things that can go wrong with an external display are:

Blank or black picture gets displayed

Blurry or wrongly-scaled picture is shown

Inaccuracies and issues with color occur

With a gist of some of the things that could have gone wrong, do any of these sound familiar to you? If so, follow along as we talk about some potential fixes to these issues.

No picture – screen is black or another color

Whenever your external display shows a black or other solid color, it typically means there’s a problem with the signal to the display, but not always. It can also mean that there is a power issue, that the brightness is too low, or something else. After you’ve first turned the external display on (because no one ever forgets to do that), here are some things you can check:

Is the display supported?

For many 4K and 5K displays, you need to be using a Mac with a graphics card powerful enough to push that many pixels. The general rule of thumb is that most modern Macs manufactured after 2013 will support such a high resolution (but not all of them). You can go to the Apple tech specs page, select your Mac, and see the displays it supports.

Is your brightness turned all the way down?

I’m guilty of this myself. One time while watching a movie in my living room, I used my MacBook Pro as a video source to my HDTV, and I turned the brightness all the way down on my MacBook Pro to direct all attention to the TV. I thought my MacBook Pro’s display was borked when I disconnected the cable because the display stayed black. Silly me, I just forgot to turn the brightness back up. This can happen with external displays too. So check your external display’s brightness level by pressing Control + F2 on your keyboard.

Check the power plug on the external display

Hey, things happen! If you live where earthquakes are common, or you have rambunctious kids running around all the time, plugs are destined to work their way out of their sockets. Check to make sure that the external displays plug hasn’t come loose or that it’s plugged in at all.

Attach your Mac notebook’s power adapter

Some Apple notebooks don’t have enough juice to push the extra pixels of an external display. One of the things Apple recommends you try if you are using an Apple notebook, such as a MacBook, MacBook Air, or MacBook Pro, is to connect the power adapter to give it additional power.

Re-seat your video connections

Eliminate the possibility of a loose display connection by unplugging your display cables and plugging them back in properly. A loose connection will keep a proper electrical connection from occurring and can cause issues with your external display.

Are you using the right port?

This doesn’t apply to most Macs, but the late 2013 Mac Pro can be relatively picky. Make sure your display(s) are plugged into the correct port(s).

Avoid video adapter chains

Apple notes that chaining two incompatible video adapters together to make your Mac compatible with one or multiple external displays can actually cause issues; as an example, you cannot connect a Mini DisplayPort to DVI adapter to a DVI to HDMI adapter and expect a picture, as it simply won’t work. If possible, remove one of the adapters and avoid chaining them together.

Does the display work with other connections?

Try using another computer or another video source and see if the display works with that video connection. If it doesn’t, then the problem could be related to the display itself and not your Mac.

Is your video cable bad?

Those cheap $0.99 HDMI eBay specials are great on the wallet, but they tend to be rather short on life. Try using a known good video cable and see if the problem persists. Often, the video cable connecting the external display to your Mac just needs to be replaced.

External screen resolution doesn’t look how it should

Problems with display resolution will cause issues with your picture. With resolution issues, your picture may look blurry or scaled incorrectly.

Typically when you plug an external display into your Mac for mirroring, your Mac will automatically adjust its own display resolution to fit the external display. Sometimes, things don’t go so smoothly. Not all resolutions translate well to others, and this will cause scaling issues that make some things look elongated or too tall.

Adjust your resolution manually

Choose the default resolution

If you’re using a scaled resolution already, this may actually be the reason your picture looks weird, to begin with. Try setting your display to use the default resolution for the display from the same preferences pane discussed above.

Reset your NVRAM and SMC

Apple also suggests resetting your NVRAM and SMC if you experience resolution issues with your external display. Resolution settings are just one of the types of information that are stored in your NVRAM, so resetting your NVRAM may help set things how they should be. Your Mac’s SMC handles display management and display ports on your Mac, and resetting your SMC may solve resolution issues.

Change resolution settings in Safe Mode

Sometimes, you may find yourself unable to change external display settings on a regular boot-up. If this ever happens to you, Apple suggests booting your Mac into Safe Mode to see if the settings can be reset to default.

Sometimes, specific apps may look blurry. If you’re using a Mac with a Retina display, you need to make sure you have the latest software installed. If just one app looks blurry, check the Mac App Store or developer’s website for any new versions of the app that might be Retina display-compatible.

Check for new drivers for your display

If every app on your display looks blurry, the display itself may need a driver update. Check the Mac App Store’s Updates tab or the manufacturer’s website for the latest driver software. Sometimes, an updated version of macOS may include pre-installed drivers, so always make sure macOS is up to date.

Problems with colors on your external display

Sometimes your display problems aren’t related to being unusable or to scaling problems, but rather to color. Maybe you have a color scheme that just doesn’t look right, an area of pixels on your screen doesn’t look right, or your display is out of calibration. Whatever the case, here are some steps you can take to correct color issues with your Mac’s external display:

Play with the display’s color profile

Calibrate your display’s color

Find the contrast button

Lots of third-party external displays not made by Apple have custom contrast buttons on them. You can typically press them on the monitor itself to adjust the contrast and make colors easier to distinguish between.

Find the color button

Like contrast buttons, some third-party external displays not made by Apple also have RGB buttons, which let you manually configure the Red, Green, and Blue levels for the display. If the display looks too orange for you, then give it some more green and blue. If it looks too blue for you, give it some more orange and green.

Adjust your brightness

The brighter your display is, the richer the colors are going to be because more light means more visibility. Your eyes use light to distinguish color. Try adjusting your display’s brightness either with the Control + F2 keyboard shortcut, or try finding a brightness button on the monitor itself.

Change display modes

Apple notes that some third-party displays have both a “monitor mode” and “television mode.” Monitor mode is going to offer the richest colors for a computer experience, and if you’re using your external display as a monitor, well, you should probably set it to monitor mode. Not all displays have this feature, but you should consult your display’s manufacturer or instructions booklet to find out more.

Do you have dead, bright, or weird pixels?

Apple refers to dead or bright pixels in a display as pixel anomalies. This can happen when individual pixels in your display malfunction and continue to emit colors incorrectly or don’t emit colors at all. It can also happen when a display gets foreign material trapped between the glass and pixel. If Apple made the display, they would be able to fix it at an Apple Retail Store or Apple Authorized Service Provider. If it’s a third-party display, you’ll have to contact the manufacturer.

Mac’s external display issues fixed

These are some of the most common issues that can occur with using an external display on your Mac. Hopefully, after trying the steps listed here, you’re able to use your external display as you once thought you’d be able to.

Make Sure Google Understands Your Images Correctly

With today’s high speed Internet connections, web publishers can afford to use as many images on their sites as they want to. While making web pages attractive and attracting visitors’ attention, images help a lot in promoting the content throughout social media.

Still, judging from recent discussions webmasters should bear in mind that images should also be treated with care. What should always be taken into consideration is that images can bring your site outside the safe search Google filter even when your overall site content (including imaginary) is completely family friendly:

Image content is harder for the machine to “understand” than text;

When it comes to images and safe search, search engines seem to prefer to err on the conservative side;

Once your images get into safe search filter, that effects the whole site and this label ca be very hard to remove.

So the first thing a webmaster should take care of is to ensure that he provides search engines with sufficient information on what his images are about:

if a webmaster fails to explain a search crawl what the image is about, a search engine will have to guess;

those guesses will not always be correct and hence will not always impact your site correctly.

How can a search engine guess?

A Google patent application covered by Bill Slawski “comes up with a method of annotation by comparison to similar images found on the Web, and the text surrounding those similar images”. Put very simply, the process of understanding the image content looks as follows:

Google comes across an image but fails to find any text content explaining what the image is about;

The system extracts image features (shapes, colors, and textures) from the image;

The system then identifies other images which have similar image features;

The system next obtains text associated with these other images, and identifies intersecting keywords in the obtained text;

The system annotates the image with the intersecting keywords.

All in all, an image is associated with keywords found with other similar images. Thus, if you want to avoid any misunderstandings, make sure you provide enough information not to let Google guess.

How can a webmaster explain what the image is about and avoid any bad associations?

Mind the image alternative text: an alt text should be concise and descriptive (not merely consisting of keywords);

Stop hotlinking: someone hotlinking to your images from an adult website can get your images filtered by safe search;

Make sure none of your image are described (with alt text, title text or surrounding text) with “bad” words (check Urban Dictionary for any keyword negative associations);

[never tried the method myself and also doubt it effectiveness] some webmasters report that ICRA labels are still used by search engines especially in niches that are “on the edge” (can be both adult and family-friendly).
