When you first turn on your Mac (or install an upgrade to the operating system), a series of questions and prompts appear, including a prompt to sign in to your Apple ID account or create a new Apple ID.An Apple ID identifies you and your devices in all things Apple that you do: registering new products, purchasing media and apps from the iTunes Store, the Book Store, and the App Store, as well as signing in to your iCloud account.

iCloud remotely stores and syncs data that you access from various devices — your Mac and other Apple devices, such as iPhones, iPads, and iPods, and PCs running Windows. Sign in to the same iCloud account on different devices, and the data for activated apps syncs; that is, you find the same data on all your devices, and when you make a change on one device, it shows up on the others.

Safari and iCloud have terrific built-in features that help you remember user names and passwords and credit card information. And Safari has security and privacy features to keep that personal information to yourself — or to your Mac. Here, we tell you how to use AutoFill so Safari remembers passwords for you, and then we explain how to keep your information safe.

Many people consider passwords to be less than ideal for security. To begin with, you have to remember them. The only sure way to make sure you don’t forget or lose your password is to write it down and keep that piece of paper (or whatever you wrote on) safe.There’s a better way if you have a current MacBook Pro or MacBook Air that supports Touch ID.

Notes is a great way to use your iPad to keep track of your busy life. If you need to add some extras for that additional bit of flare, try inserting a photo, video, drawing, or sketch. Insert a photo or video into a note Want others to see your great photo or video. That’s easy. With Notes open, tap to create a new note or tap to edit an existing note.

Notes is a great app that comes preinstalled on your iPad. It has several different options for helping you manage all of the things you need to do on a busy schedule. You can take down groceries, make a to-do list or keep track of anything that comes to mind.You can even apply text styles to your note. Text styles — including Title, Heading, Body, Bulleted List, Dashed List, and Numbered List — are available on the new shortcut toolbar above the onscreen keyboard.

Your iPad helps you manage your schedule with Calendar. If you set up the Family Sharing feature, you can create a group calendar to share events with up to five other people. After you set up Family Sharing, you have to make sure that the Calendar sharing feature is on. Tap Settings →   iCloud to open the iCloud screen.

iTunes and the iPad offer support for closed captioning and subtitles. If a movie you purchased or rented has closed captioning or subtitles, you can turn on this feature in iPad. Look for the CC logo on media you download to use this feature. Video that you record won’t have this capability. Tap Settings →   General →   Accessibility.
