How to automatically back up your Mac with Time Machine

Whether you're using one of the newest Macs with macOS Sequoia or an older Mac with a hard drive, having a data backup solution is a must. Luckily, all Mac desktops and laptops come with Time Machine — a native backup utility that can automatically save your data at selected intervals. In this guide, we'll show you how to set up Time Machine, and make sure you're covered in the event something goes wrong with your computer, storage drive, or macOS instance.

Things to know before you get started using Time Machine

For starters, you'll need an external drive with enough free space

For those that are new to Time Machine, it's a native macOS backup utility that makes it easy to take snapshots of your system data. If, for some reason, you encounter an issue with your Mac or your macOS instance, these Time Machine snapshots will give you a point to restore from with minimal or zero data loss. That's why using Time Machine is essential, even if you back up your Mac using a cloud service, like iCloud.


Time Machine makes hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months, according to Apple Support. These backups are saved until your Time Machine disk if full, at which point the utility will automatically delete the oldest backups to make room for new ones. As such, there is a benefit to using a larger drive. Minimally, Apple recommends you use a hard drive or SSD with double the storage of your Mac's internal drive. Any USB or Thunderbolt drive with enough storage should do the trick.

If you plug in your drive and see a message like This drive is not readable by this computer, follow the on-screen prompts to Initialize the drive. This will make the drive readable by your Mac, and by extension, Time Machine.
