Time Machine is undeniably one of Apple's most valuable features, and knowing how to restore from Time Machine is a helpful skill for any Mac user.

Since its first appearance back in 2007, the built-in Time Machine app from Apple has become a simple and effective way for users to back up their personal data, recover individual files, or restore their devices. Not only is Time Machine free, but it's also easy to use.

If you've ever suffered from data loss — be it via hard drive failure, stolen device, virus, or corrupt files — you'll know just how important it is to carry out regular backups.

In this article, we'll walk you through the steps required to restore your Mac from a previous Time Machine backup, so let's get started.
