Use Time Machine to back up or restore your Mac – Damean Sellar
How to Backup or Restore using Time Machine
Time Machine backs up all of your files to an external hard drive so that you can restore them later or see how they looked in the past.
Set up Time Machine
Time Machine is the built-in backup feature of your Mac. To use it, you need an external storage solution, sold separately:
- External hard drive connected to a USB, FireWire, or Thunderbolt port on your Mac
- Time Capsule or macOS Server on your network
- External hard drive connected to the USB port of an AirPort Extreme base station on your network
When you connect an external hard drive directly to your Mac, you might be asked if you want to use the drive to back up with Time Machine. Click “Use as Backup Disk.” If you select the option to encrypt, your backups will be accessible only to users with the password.
If Time Machine doesn’t ask you to choose a backup disk:
- Open Time Machine preferences from the Time Machine menu in the menu bar. Or choose Apple menu () > System Preferences, then click Time Machine.
- Click Select Backup Disk, Select Disk, or Add or Remove Backup Disk.
- Select a backup disk from the list, then click Use Disk.
- For additional backup security and convenience, you can repeat these steps to add another backup disk. For example, you might use one backup disk while at home, and another backup disk while at work.
