Apple first unveiled 3D Touch in iOS 9 with the iPhone 6s and 6s Plus, giving users of those iPhones a new way of interacting with apps, but 3D Touch didn’t catch on until Apple released the iPhone 7 and 7 Plus, and gave it broader support in iOS 10. Another year later, and 3D Touch is absolutely worth learning if you have a supported iPhone.

3D Touch works in two ways: peek and pop and quick actions.

Apps use peek and pop to let you glance (peek) at an item by pressing down on it (not just a touch, but a press into the screen), and then jump to that item (pop) by pressing harder still. In Safari, for instance, you can preview a link by pressing it, and then either release to dismiss the preview or continue to load it in its own tab by pressing harder. Or move your finger up on the screen without letting go or pressing harder to get controls for opening the link, adding to your reading list, or copying the URL. This trick applies to links in other apps like Mail, Messages, and Notes, too.

You can also use peek and pop with email message summaries in Mail, headlines in News, thumbnails in Photos, people in Find My Friends, dates and events in Calendar, and even the previously taken photo box in Camera. Support for peek and pop in third-party apps isn’t as widespread as it is in Apple’s apps, but it’s still worth trying whenever you want to preview something.

More interesting are quick actions, which present a menu of common actions when you press down on an app’s icon on the Home screen, or on various other items throughout iOS. Home screen quick actions are great, since they let you kickstart an app into doing something with just a hard press on its icon. If the app has a widget, pressing the icon shows that as well.

For instance, pressing on the Phone app shows its widget, which gives you buttons to call people in your Favorites list, along with actions to view the most recent call, search for a contact, create a new contact, or view the most recent voicemail. The Clock app lets you start a timer or the stopwatch, or create an alarm. Messages quick actions can create a new message or open a recent conversation. Press Safari’s icon, and you can create a new tab or see your bookmarks or reading list. You can even press on a folder to rename it quickly.

Quick actions and widgets are much more commonplace among third-party apps than peek and pop support, so be sure to try 3D Touch on all your favorite apps. If all you see is a Share item, the app has no quick actions or widget, but many apps provide both static actions that are always the same and dynamic actions that reflect your past usage.

Starting with iOS 10, you can use 3D Touch in Control Center too. Press the Flashlight button to adjust the brightness of the light, the Timer button for some pre-canned times, the Calculator button to copy the last calculation result, or the Camera button to take a photo, slo-mo, video, or selfie.

On the Lock screen, some notifications work with 3D Touch. For example, press a Messages notification to expand it and reply directly from the notification. And in Notification Center, you can press a notification to expand it, or use 3D Touch on the X button for any day to reveal a Clear All Notifications option.

It’s too bad that there’s no way to know in advance if an app supports quick actions or peek and pop, but as the number of iPhone users who can use 3D Touch increases, developers will incorporate 3D Touch capabilities into their apps more and more. So give it a try!

To every thing there is a season, and we’re fast approaching the time when Apple harvests the fruit of the last year and releases new versions of macOS, iOS, watchOS, and tvOS. There are no major surprises here, since Apple announced the new versions in June and public betas have been available since that announcement. But once macOS 10.13 High Sierra, iOS 11, watchOS 4, and tvOS 11 become available for free download, you’ll need to decide when you’re going to install them.

(Note that we say when and not if. There’s no harm in delaying major operating system upgrades until Apple has had a chance to squash the initial bugs and you have time to focus on the task. But waiting too long puts you at risk from security vulnerabilities and prevents you from taking advantage of new integrations between Apple’s devices. Plus, should you have to replace an Apple device unexpectedly, you will likely be forced to use the current operating system, which could be awkward if you weren’t ready for the upgrade.)

The hardest decision to make is with macOS 10.13 High Sierra. In keeping with Apple’s cycle of macOS upgrades, High Sierra focuses on under-the-hood enhancements, most notably the switch to the new APFS file system and behind-the-scenes HEVC/HEIF formats for videos and photos. But apart from improved performance and reduced storage needs, neither of those changes will impact your everyday Mac experience. Tweaks to apps like Photos, Safari, and Messages will also be welcome but are far from essential. So our recommendation is to wait until at least version 10.13.1 or even 10.13.2 before upgrading. That gives you time to make sure your key apps are compatible with High Sierra and for Apple to resolve any unanticipated problems.

What about iOS 11? Although iOS 11 has received good reviews from beta testers, if you rely on an app that isn’t compatible, you may want to delay your upgrade. Check the App Store listing for each of your key apps, and if they’ve been updated recently, you’re probably OK to upgrade. If you use an iPad, install iOS 11 only once you’re ready for a major interface change, what with the new Dock, the redesigned Control Center, the new Files app, and improved multitasking and drag-and-drop. It’s all good, but it’s noticeably different. Apart from that, we see no significant reason to hold off on iOS 11—you’ll likely appreciate most of its new features.

The question of when to upgrade gets easier with watchOS 4. Although it has some nice new features, like a Siri watch face, improvements to Activity, more workout features, and better integration with Apple Music, it’s not a sea change. With no notable downsides to upgrading, it’s easy for us to recommend upgrading your Apple Watch as soon as you take your iPhone to iOS 11.

The easiest upgrade decision is moving to tvOS 11. If you have a fourth-generation Apple TV, either let it upgrade itself to tvOS 11 or invoke the upgrade manually from Settings > System > Software Updates. Since tvOS 11 is a minor update and you don’t create work on an Apple TV, upgrading is unlikely to cause any problems. You’ll just enjoy the automatic dark and light mode, support for AirPods, and AirPlay 2.

As much as change can be hard, we’re excited about Apple’s new operating systems. Like you, we probably won’t end up using all the new features, but some will definitely enhance the experience of being an Apple user.

Twitter: macOS 10.13 High Sierra, iOS 11, watchOS 4, tvOS 11—when should you upgrade? We have the answers you need at:

Facebook: Apple is releasing four major operating system upgrades later this year—macOS 10.13 High Sierra, iOS 11, watchOS 4, and tvOS 11. They promise improved performance and some compelling features… but when should you upgrade? (Hint: Not necessarily right away.)

When you want to share a Web page link from Safari to Messages, search within a page in Safari, or save a PDF to iBooks, you tap the Share  button to bring up iOS’s Share sheet. If a large number of apps can accept the shared item, you might have to scroll to the right quite a bit to get to the icon you want. For occasional use, that’s fine, but there’s no need to scroll each time, since you can rearrange the Share sheet icons. Just touch and hold on the one you want to move, and then drag it right or left, lifting your finger to drop it in place. This trick works for each row in the sheet. Next time you’re in a Share sheet, take a moment to customize it the way you want.

It’s easy, in some apps, to end up with oodles of open windows. You can usually switch between them by clicking those you can see or by choosing one from the Window menu, but wouldn’t it be nice to cycle through them from the keyboard, much as you can cycle through active apps with Command-Tab? You can! By default, the shortcut is Command-Backtick (the key above Tab), but if you want to change it to something else, open System Preferences > Keyboard > Shortcuts > Keyboard and look for “Move focus to next window” in the list. To change the shortcut, double-click right on it in the list and type your preferred alternative.

Picture yourself looking for something specific on a long Web page on the small iPhone screen. Did you know that you can search through just the text of the page? Tap the Share  button, and in the bottom row of icons, swipe left until you see Find on Page. Tap that, and then enter the word you’re looking for in the search field that appears. The Up and Down arrow buttons in the upper left of the keyboard help you find other instances of your search term.

Assuming Apple continues its previous practices, once macOS 10.13 High Sierra comes out, it will become impossible to download 10.12 Sierra for the first time. That could be awkward if you want to upgrade an older Mac to Sierra at any point after High Sierra ships, since you won’t be able to get Sierra then. To ensure that you can snag a copy of Sierra in the future, open the App Store app on your Mac, type Sierra in the Search field, and click the Get button for macOS Sierra (it’s about 5 GB in size). It downloads to your Applications folder, and the installer launches automatically. If you don’t want to install Sierra right away, choose Install macOS > Quit Install macOS to quit the installer. What’s important is that Sierra is now registered to your Mac App Store account, and you can get it again from the App Store’s Purchased screen at any time on any of your Macs.
