iCloud Photos (which Apple previously called iCloud Photo Library) is wonderful when it’s working. Take some photos on your iPhone, and they appear on your Mac and iPad a minute later. Delete unnecessary shots and edit the others on your Mac, and your iPhone and iPad reflect those changes almost immediately. But what if changes aren’t syncing? Photos in iOS and macOS can pause syncing for a variety of reasons, and sometimes it doesn’t restart when it should. To see if this is happening, go to the very bottom of the Photos view in Photos, where it lists the number of photos and videos you have stored. Below that number is the sync status. If it has a reason and a Resume link, click or tap Resume to start it again.
Here’s How Apple Changed Sending a Photo in Messages in iOS 12
Before iOS 12, you’d tap the camera button in a Messages chat in order to share either a brand-new photo or a photo that had already been taken. In iOS 12, Apple changed things so tapping the camera button only lets you take a fresh photo. To find and send a photo that’s already in Photos, use the Photos mini-app in Messages. If necessary, tap the Apps button to the left of the message field to show the Messages apps, and then tap the Photos button to see a list of recent photos. Tap one or more to add them to the message, and you’re ready to send!
The Secret Keyboard Shortcut for Comparing Before/After Edits in Photos on the Mac
Photos on the Mac provides so many editing tools that it’s easy to lose track of how an edited image compares to the original. You can always use the Revert to Original command and then undo it, but that’s fussy. Instead, Photos provides a Show Original 
button in the upper-left corner, between the window controls and the Revert to Original button. Click and hold it to see your original image; let up to see the edited version again. Even easier, press the M key on your keyboard. The only thing either of those techniques won’t do is show the effect of cropping; to see the uncropped original, press Control-M. And if you just want to see how a particular set of adjustment controls affected the image, click its blue checkmark 
to turn it off and back on.
Remember That You Can Search for Nearly Anything in Your Photos Library
Apple’s Photos app on the Mac can identify thousands of different objects in your photos, so it’s easy to find photos based on their content. You can find objects (cars and trains), scenery (beaches and forests), and even some events (weddings and parades). This is both big fun and useful for those times when you can’t remember when you took a photo, but do remember what’s in it, like a cat, camera, or carousel. To carry out a search like this, type the search term into the Search field on the right side of the Photos toolbar. From the list that appears, choose the Category result. In macOS 10.13 High Sierra’s version of Photos, you can filter your results from the Showing menu at the upper right of the window. The feature isn’t perfect, so you may see some odd results or miss some photos, but it’s way faster than browsing manually!
Let Your Fingers Do the Walking: 13 Essential Trackpad Tricks for Mac Users
A trackpad is not a mouse. In some ways, that’s obvious—you swipe your fingers on it, rather than dragging it around. Less obvious, however, are the many gestures that make using a trackpad on your Mac faster and more fun. These gestures aren’t limited to laptop users, thanks to Apple’s Magic Trackpad 2, which brings gesturing goodness to any desktop Mac. Here’s how to put your fingers to work.
Four Fingers on the Trackpad
The four-fingers-down gestures are dramatic and an easy way to appreciate the power of trackpad gestures, so we’ll start with them.
Say you have a lot of windows open, and you want to move them all aside quickly so you can open a file on the Desktop. Place your thumb and three fingers together on your trackpad and then spread them outward. Your windows scurry to the edges of the screen. To bring the windows back, reverse the gesture, pinching your fingers in toward your palm.
If you haven’t moved windows aside, pinching your thumb and three fingers together instead opens Launchpad, which shows icons for installed apps. Click an icon to open that app, or use the spreading four-fingered gesture to exit Launchpad.
Three Fingers on the Trackpad
Move three fingers horizontally on your trackpad and either nothing will happen, or you’ll switch to a different “desktop space.” This state of affairs is most easily seen by making an app full-screen. For instance, open Safari and click the green full-screen button at the upper left of the window. Safari takes over the entire screen, including the menu bar (to put it back, hover the pointer at the very top of the screen to see and click the green button again).
Now swipe left and right horizontally to switch in and out of the Safari space. As you make more apps full-screen, they’ll each create their own space. (If you’ve enabled Apple’s Dashboard, you may see it at the far left.)
What if you swipe vertically with three fingers? Swipe up to enter the All Windows view of Mission Control, which shows all open windows as thumbnails, plus desktop spaces in the top bar. Click any thumbnail to switch to it, or jump to any space by clicking it. You can also click the plus button at the upper right or drag any window into the top bar to create a new space. To move a space’s apps back to the current space, hover over a space on the top bar and click the close 
button that appears. To exit All Windows view, swipe down with three fingers.
If you haven’t invoked All Windows view, swiping down with three fingers instead invokes App Exposé view, which displays thumbnails of all open windows in the current app. Click any one to switch to it. Swipe right or left with three fingers while in App Exposé to switch between apps.
Finally, on older MacBooks that don’t have Force Touch-capable trackpads, tap with three fingers on words to look them up, on files to preview them with Quick Look, and more. With newer MacBooks, if you have “Force Click and haptic feedback” enabled in System Preferences > Trackpad > Point & Click, you can instead “force click” with one finger for these features. That involves clicking on something and then pressing firmly without letting up.
Two Fingers on the Trackpad
The two-fingered gestures are easy to get your head around:
- In Safari, swipe left on a page to go back in that tab’s page history or right to go forward.
- Also in Safari, tap two fingers on the trackpad to zoom in on the content. Another two-fingered tap zooms back out.
- In Photos, and some graphics apps, zoom in and out by pinching with two fingers, and rotate selected objects by putting two fingers on the trackpad and turning them. A two-finger pinch also zooms the page in Safari.
- To open Notification Center quickly, swipe left from off the right-hand edge of your trackpad. Swipe back to the right to close Notification Center.
Changing Your Preferences
If you need a refresher on all these gestures, open System Preferences > Trackpad. Look in the Point & Click, Scroll & Zoom, and More Gestures panes to see a video for each gesture. You can also adjust which ones are active and how many fingers they require.
With so many gestures on offer, it’s worth your time to explore everything you can do with your trackpad.

Apple Is Discontinuing Its Photo Printing Services—Here Are 7 Alternatives
Sad news: Apple is discontinuing its photo printing services, which enabled you to create and order physical prints, cards, calendars, and books from within Photos on the Mac. If you’re building such a project right now, be sure to place your order before September 30th, 2018. After that, Apple is directing users to download a Photos Project Extension from the Mac App Store. You’ll see this dialog whenever you click a project in Photos.
When you click the Open App Store button, Photos opens the App Store app and shows available Photos Project Extensions. (If you need to open this Mac App Store screen manually, search on appex:com.apple.photo-project.) Most of these extensions are free, since they’ll make their money when you order projects.
These extensions aren’t exact replacements for Apple’s projects, so let’s look briefly at what they provide.
Mimeo Photos
The extension that comes closest to providing the same products and features as Apple’s print projects is Mimeo Photos, which can create cards, calendars, and books. It offers a wide array of themes.
Motif
Motif looks quite similar to Mimeo Photos, also enabling you to create cards, calendars, and books with selected photos, and it comes from RR Donnelley, the company that was previously Apple’s partner for print projects. It doesn’t offer as many themes or options as Mimeo Photos, but it has a better interface.
Shutterfly
Even though the popular Shutterfly photo service’s Web site lets you go beyond the basics to put your photos on a vast number of objects, such as pillows, candles, and trivets, the company’s Photos extension is limited to photo books. Happily, it provides quite a few different sizes and bindings, and numerous themes for each.
Fujifilm Prints & Gifts
The Fujifilm Prints & Gifts extension lets you order prints, cards, wall art, mugs and drinkware, magnets, T-shirts, puzzles, iPhone cases, and much more. However, it has a non-standard interface (basically the company’s Web site), and every time we switched out of the extension, it crashed and forgot which photo we’d had selected.
Mpix
Although Mpix seems to focus on prints, if you scroll down in the project list, the final option is Browse Mpix, which provides more possibilities, including photo books, calendars, collages, foil art prints, posters, keychains, magnets, playing cards, and business cards. Confusingly, with some of these items, Photos acts as nothing more than a window onto Mpix’s Web site, with no awareness of the photos you’ve selected.
WhiteWall
WhiteWall focuses entirely on prints, with high-end choices for exotic papers and options for mounting and framing. Supported sizes range from 8″ x 6″ up to 48″ x 36″. Unfortunately, the WhiteWall prices seemed high (a framed photo was between $130 and $530, depending on size), and once you select a particular paper or frame choice, there is no way to try another with the same photo without starting another project.
Wix
Unlike all the others, the Wix extension doesn’t put photos on physical products at all. Instead, it’s designed to create on-screen photo albums for Web sites designed with the Wix service. As such, it’s potentially extremely useful for Wix users, but not at all for everyone else.
It’s too bad that Apple is getting out of the print project business since the interfaces from these extensions tend not to be as good as what we’re used to from Apple. But if you like making yourself a calendar every year, you’ll probably do fine with Mimeo Photos or Motif, and the rest of the extensions do extend Photos’ printing capabilities in a big way.
Social Media: As of September 30th, you won’t be able to order prints, cards, calendars, or books from Apple in Photos. But several extensions do most of what Apple did, and others go well beyond!
