It’s the time of year when Apple rolls out major operating system upgrades, and we know it’s tempting to push the “update” button when it appears on your Mac, iPhone, or iPad right away. Before you install, though, make sure you have a solid backup in place. If you should happen to be among the unlucky few who end up with a bricked iPhone, inactive iPad, moribund MacBook, or kernel-panicking iMac after updating, your options for a happy outcome go up astronomically if you have a current backup. For an iOS device, back up to either iCloud or iTunes. On the Mac side, make sure your Time Machine backup is up-to-date or create a bootable duplicate with SuperDuper or Carbon Copy Cloner.
