After you hit the power button on your Mac computer, the computer will boot and is ready for your use. Macs are reliable computers in terms of both hardware quality and operating system stability. However, virus infection, unsuccessful system upgrade, or other reasons can result in a corrupted boot volume and then an unbootable computer. As a result, you can’t access the data on the Mac and you don’t have a computer to access the data on external disks either.
Your Mac might be stuck on the loading bar or show black screen and refuses to boot into the desktop. You probably think your data is permanently gone and your Mac might be dead. Before you go to Apple store for help, read this post to save your day.
Restore the Mac from Time Machine Backup
Never heard of Time Machine? Well, Time Machine is a built-in backup application on Mac. You can attach an external disk to the Mac and set up the Time Machine to automatically back up all your files including system files and the files you created. Once the files are deleted, damaged or lost, you can restore them from Time Machine backups.
If you have Time Machine backups before your Mac breaks down, things will be a lot easier.
- Restart your Mac and hold down Command + R immediately.
- Release the keys after you watch the Apple logo appearing.
- Connect Time Machine disk to the Mac.
- Select “Restore From Time Machine Backup” from macOS Utilities menu.
- Select a file that you want to restore the computer to.
- Click on “Restore”.
Then the computer will restore to the state from the Time Machine backup. You are all good to go.
