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.

Some Web sites have separate desktop and mobile versions, each theoretically providing the best browsing experience for its platform. Unfortunately, mobile Web sites sometimes leave out necessary features or hide content. That’s especially annoying if you’re browsing on an iPad, where the desktop site would work fine. If you run across such a site while browsing in Safari on the iPhone or iPad, you can ask for its desktop version. Press and hold the Reload button at the right side of the address bar, and then tap Request Desktop Site. If the site allows such a request, as do Wikipedia and the New York Times, the desktop version loads (to read the small text, you may need to pinch out to zoom the page).

On the face of it, Apple’s Find My iPhone feature does what it says. If you lose your iPhone, you can identify its last known location by looking in the Find iPhone app or on the iCloud Web site, and you can make it play a sound. It’s great for tracking down a missing iPhone, whether you misplaced it in the house or left it behind at a restaurant.

But Find My iPhone does much more! For starters, it works with nearly any Apple device. You can use it to locate a missing Mac, iPad, iPod touch, Apple Watch, and even AirPods. Find My iPhone also helps protect your data if a device is stolen. It even works with Family Sharing to locate devices owned by anyone in your family—a boon to any parent with a forgetful teenager.

You must turn on Find My iPhone before your device goes missing!

• In iOS, tap Settings > Your Name > iCloud > Find My iPhone and enable Find My iPhone. (On the iPad, it’s called Find My iPad.) Also on that screen, turn on Send Last Location. Finally, go back to the main level of Settings, tap Privacy > Location Services, and make sure Location Services is turned on.
• On the Mac, open System Preferences > iCloud and select the Find My Mac checkbox—if you see a Details button beside Find My Mac, click it and follow its instructions for setting necessary preferences.

Be sure to practice viewing where your devices are located and playing tones on them so you’ll know what to do if a device goes missing.

Find My iPhone has a few tricks up its sleeve for when you want a device to show a message or if you think it was stolen:

• Lost Mode: When invoking this mode for an iOS device or Apple Watch, you’ll be asked to enter a phone number where you can be reached and a message. After that, Lost Mode will kick in as soon as the device is awake and has an Internet connection. Anyone who tries to use the device will see your message along with a place to enter the device’s passcode. If you get it back, you can enter the passcode to dismiss the message and use it normally.
  
• Lock: Available only for the Mac, the Lock feature enables you to protect an entire Mac with a 4-digit custom passcode. You can also enter a message that will appear on the Lock screen. This is a good choice if you think you’ll get your Mac back but would prefer that nobody mess with it in the meantime. Note that if you lock a Mac, you can’t erase it, as discussed next, so lock it only if you think it can be recovered.
  
• Erase: Even if your device has an excellent passcode or password, you might worry that a thief will access your data. Fortunately, you can erase your device. Erasing a device makes it impossible for you to see its location in Find My iPhone, so it’s a last-ditch effort.
• Activation Lock: If the stolen device is an iOS device or an Apple Watch, when you turn on Find My iPhone, you also enable Activation Lock. This feature prevents someone who has your passcode but doesn’t know your Apple ID and password from turning off Find My iPhone, erasing the device, or setting it up for a new user. In other words, Activation Lock makes it so there’s little reason to steal an iOS device or Apple Watch, since the stolen device can’t ever be used by anyone else. If you get the device back, you can restore your backup—you do have a backup, right?

Find My iPhone works only while the device has power, so if you think you’ve mislaid a device, try locating it right away, before the battery runs out. But even if you are unable to retrieve a lost device, you can prevent others from accessing your data or taking over the device.

Productivity experts recommend offloading things you have to remember to a task-management app like Apple’s Reminders, which syncs your to-dos among your Mac, iPhone, iPad, and Apple Watch. That’s particularly helpful for tasks you want to be reminded of in a few months or next year, but then those far-in-the-future tasks—especially repeating ones!—clutter your main Reminders list. The solution? Create a Far Future Reminders list, and move reminders to it that aren’t relevant within the next month or so. Just make sure everything in Far Future Reminders is set to alert you on the appropriate day.

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.

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.

When a Mac folder contains a lot of files, the Finder’s List view often works best, since it lets you focus on a single folder and easily sort the contents by clicking the different columns: Name, Date Modified, Size, and Kind. But did you know that you can resize columns, rearrange them, and even add and remove columns? To resize a column, drag the vertical separator line to the right of its name. To move a column, click and hold on its name, and then drag it to the desired position. And to add or remove a column, Control- or right-click any column header and select or deselect the desired column. Choose from Date Modified, Date Created, Date Last Opened, Date Added, Size, Version, Kind, Comments, and Tags.

Most Macs are busy places, with oodles of open windows cluttering the screen. If you want to look at the Desktop or do something different, you may find yourself clicking around or using keyboard shortcuts, but did you know that you can access many of the Mac’s special views with just a flick of your wrist?

A little-known feature called Hot Corners makes this possible. The key to unlocking Hot Corners is in System Preferences, in either the Desktop & Screen Saver pane or the Mission Control pane. In either pane, click the Hot Corners button to set up your hot corners.

The Hot Corners dialog displays a pop-up menu for each of the four corners of your screen. Choose an action in one of those menus, and that’s what happens when you move your pointer to that corner. A hyphen, the default, means nothing happens. Here’s the scoop on each action.

Start Screen Saver

With today’s flat-panel LCD screens, a screen saver isn’t needed to prevent image burn-in, but it does hide the contents of your screen and personalize your Mac. The Start Screen Saver hot corner shows the screen saver immediately, overriding the setting for how long the Mac must sit idle before the screen saver turns on (in System Preferences > Desktop & Screen Saver > Screen Saver, in the Start After pop-up menu).

Disable Screen Saver

If you normally have your screen saver set to turn on automatically, it may come on when you would prefer it didn’t, such as when you are thinking about what to write in a tough email. To prevent the screen saver from coming on temporarily, use a Disable Screen Saver hot corner.

Mission Control

Once you’re in this bird’s-eye view of all your Mac’s open windows, you can switch to any window by clicking it. You can also set up spaces in Mission Control—a space is a view that contains only windows from the apps that are assigned to that space. Click the plus sign in the top-right corner and then drag windows up into the new space. Switch to a space by clicking it in the top bar.

Application Windows

For an overview of all open windows for a particular app, use a hot corner to invoke Application Windows. This view displays thumbnails of all open windows in the current app. For some apps, you’ll also see thumbnails of recently opened documents at the bottom of the view. Click any thumbnail to switch to it.

Desktop

If you like storing documents for in-progress projects on your Desktop, you’ll love the hot corner that invokes Desktop view. It moves all open windows aside, letting you focus on the icons on the Desktop. The windows return when you switch to an app.

Dashboard

Dashboard contains a few rudimentary widgets, like a clock and a calculator. Apple hasn’t updated Dashboard in years, and developers don’t create Dashboard widgets anymore, so it’s not worth learning—or using via a hot corner—if you don’t already rely on it.

Notification Center

Since you can so easily click the Notification Center icon in the far right of your menu bar, it’s seldom worth wasting a hot corner on it. Notification Center has two views: Today and Notifications. Today shows status information and is easily customized; click the Edit button at its bottom. To display an app’s notifications in Notifications, go to System Preferences > Notifications, select the app, and then select the Show in Notification Center checkbox.

Launchpad

If you like using iOS, giving Launchpad a hot corner might make opening apps on your Mac easier. It’s designed to look and work like the Home screen on an iPad or iPhone—just click an app to launch it. To see more apps, scroll horizontally—with a trackpad, swipe with two fingers; with a Magic Mouse, scroll by swiping with one finger on the mouse surface.

Put Display to Sleep

Those who are concerned about energy usage might appreciate this option. Toss your pointer in the associated hot corner, and your screen goes to sleep immediately, consuming less power than a screen saver. It lets you override the “Turn display off after” slider in System Preferences > Energy Saver.

To exit these special views, switch to another app, press the Escape key, put the pointer back in the hot corner again, or just move the mouse.

If you find yourself triggering a hot corner accidentally, try adding a modifier key so its action activates only when the pointer is in the corner and the key is pressed. To set this up, open the Hot Corners dialog, open the corner’s pop-up menu, and press a key (Shift, Control, Option, or Command). The key’s symbol appears in the menu. Keep the key down and choose the desired action.

The best way to set up your hot corners depends on how you use your Mac, of course. Our favorites are Start Screen Saver because it’s a quick override of the screen saver settings and Desktop because it removes screen clutter that gets in the way of using the Desktop.

Social Media: Did you know that you can turn on certain Mac features by sliding the pointer to a corner of the screen? Here’s how:

As students prepare to head off to college, Apple has updated the Touch Bar-equipped MacBook Pro line to provide even more powerful options for students and professionals alike. The changes are primarily under the hood, focusing on faster performance, more RAM, and larger SSD-based storage, but there are a few modest physical changes too, including a quieter keyboard and a True Tone display.

Despite these improvements, pricing remains the same as for last year’s models.

The 13-inch MacBook Pro that has function keys instead of a Touch Bar remains the same, as do the 12-inch MacBook and 13-inch MacBook Air.

Performance Boosts

The new MacBook Pros move to Intel’s 8th-generation Core i7 and Core i9 processors. Previously, the 13-inch MacBook Pro used dual-core CPUs, but they now get quad-core chips. And the 15-inch models jump from quad-core chips to processors sporting 6 cores. More cores are better because more tasks can be split up between them, preventing one processor-intensive task from bogging down others.

Processing power is just one aspect of overall performance. If your Mac doesn’t have enough RAM for the apps you’re using, it has to fall back on much slower virtual memory. For those who use memory-intensive apps, the new 15-inch MacBook can now take up to 32 GB of RAM, up from a maximum of 16 GB. RAM in the 15-inch models is also DDR4, which is faster and uses less power than the DDR3 RAM used before.

Finally, if you don’t have enough fast SSD storage in a MacBook Pro, you may be forced to store large items like your Photos library and Parallels Desktop virtual machines on a slow external hard disk. The new MacBook Pros can have a lot more built-in SSD storage, but it’s pricey. The 13-inch models max out at 2 TB, which will add $1400 to your bill, and the 15-inch models can go to 4 TB, assuming you have $3400 to spare. The 512 GB ($200) and 1 TB ($600) upgrades are more reasonably priced.

Physical Changes

Apple continues to tweak the controversial butterfly-switch keyboard. Some people haven’t liked the shallow key travel and how much noise it makes, and its keys have a tendency to stick. The new MacBook Pros feature a keyboard that’s quieter and hopefully more reliable.

You’ll also notice the new Retina displays with True Tone. First introduced with the iPad Pro and added to the iPhone in 2017, True Tone adjusts the white balance of the screen based on ambient light to make the screen more comfortable to view. It should be particularly appreciated by students working late into the night.

Other Improvements

You know how you can issue commands to Apple’s virtual assistant on your iPhone or iPad by saying “Hey Siri”? That’s possible in the new MacBook Pros also, thanks to the inclusion of Apple’s new T2 chip. The T2 also manages the Touch Bar, facilitates a secure boot feature, and encrypts files on the fly to increase security.

These MacBook Pros are the first to support Bluetooth 5.0, which is backward compatible with Bluetooth 4.2. As Bluetooth 5.0 peripherals become more widespread, they’ll be able to communicate with the MacBook Pro at higher data rates and longer ranges—think of Bluetooth working across your entire house, rather than being limited to a single room.

Price and Availability

The entry-level 13-inch MacBook Pro starts at $1799, and the 15-inch model at $2399. With both models, you can choose between silver and space gray, and they’re available now.

Our take is that, like most of Apple’s speed-bump upgrades, these new MacBook Pros are simply better than the previous models—who turns down better performance for the same price? The True Tone display is also welcome, as is the quieter keyboard. And it’s nice that we can finally talk to Siri without having to hold down a key or click a button.

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!
