Unless you can palm a basketball, you may not be able to use an iPhone single-handed. But sometimes one hand is all you can spare. If you find yourself in such a situation, give Reachability a try. On a Touch ID–based iPhone, tap (don’t press) the Home button twice to slide the iPhone’s interface halfway down the physical screen, bringing everything into reach of your thumb. On the Face ID–equipped iPhone X, put your thumb in the bottom of the screen—about at the top edge of the Dock if you were on the Home screen—and swipe down. You can use apps normally for a tap or two, and then they’ll expand back to the full screen to show the full interface. If Reachability is off (or if you want to turn it off), go to Settings > General > Accessibility.
Have you ever wanted to insert a photo or scanned page into an email message or document? Mojave makes this easier with Continuity Camera, a feature that lets you use your iPhone within a Mac app. In Mail, for instance, start a new message, and then choose File > Insert from iPhone > Take Photo/Scan Documents. Either way, your iPhone immediately switches to the appropriate photo or scanning mode, and the resulting photo or scan lands in your message.
In the “it’s about time” department, iOS 12 beefs up Do Not Disturb so it works more the way people do. When you bring up Control Center and force-touch the Do Not Disturb button, it expands to let you turn on Do Not Disturb for 1 hour, for the rest of the day, or until you leave your current location. The beauty of these new options is that they disable Do Not Disturb automatically so you don’t have to remember—and potentially miss important notifications. Plus, a new Bedtime option in Settings > Do Not Disturb dims the display and silences overnight notifications until you unlock your device in the morning.
When you register your fingerprints with Touch ID or train Face ID to recognize your face, it’s reasonable to worry about that information being stored where attackers—or some government agency—could access it and use it for nefarious purposes. Apple was concerned about that too, so these systems don’t store images of your fingerprints or face, but instead mathematical signatures based on them. Those signatures are kept only locally, in the Secure Enclave security coprocessor that’s part of the CPU of the iPhone and iPad—and on Touch ID-equipped laptops—in such a way that the images can’t be reverse engineered from the signatures.
People with medical conditions can be concerned about health information impacting health insurance bills or a potential employer’s hiring decision. To assuage that worry, Apple lets you choose what information ends up in Health app, and once it’s there, encrypts it whenever your iPhone is locked. Plus, any Health data that’s backed up to iCloud is encrypted both in transit and when it’s stored on Apple’s servers.
A linchpin in Apple’s approach to privacy is its control over the App Store. Since developers must submit apps to Apple for approval, Apple can enforce stringent guidelines that specify how apps can ask for access to your data (location, photos, contacts, etc.). This isn’t a blanket protection—for instance, if you allow a social media app <cough>Facebook<cough> to access your contacts and location, the company behind that app will get lots of data on your whereabouts and can even cross-reference that with the locations of everyone in your contact list who also uses the service.
