Backup your Mac with Time Machine
DISCOVER THE POWER OF TIME MACHINE AND VERSIONS TO RECOVER YOUR FILES.
YOUR MAC COMES with a built-in backup system called Time Machine that’s very easy to use. It only takes a minute or two to get started and, once set up, it then backs up any changes made to the files on your Mac roughly once an hour. It’s easy to overlook some of this feature’s capabilities, so this cheat sheet gives an overview of the various ways to recover changed words, files you’ve trashed by mistake, or even your whole setup if a big problem occurs or you buy a new Mac.
If you use a portable Mac, you may notice different coloured notches in Time Machine’s timeline. Bright red represents local snapshots, which are explained opposite. By upgrading to High Sierra, you stand to benefit from an important improvement to when local snapshots are taken: your MacBook will create one immediately before any update to macOS itself is installed, providing a fallback should something go wrong during the update.
