Time Machine is a great tool that automatically makes your Mac backups using one of the best external hard drives on the market. What's really great about it is that it's built into macOS itself, so every Mac comes with it automatically. It's fairly simple to set up, and after that, you don't even need to worry about it. But if you want to, you can customize your Time Machine experience to your particular needs. Here's how to back up your Mac with Time Machine.

What is Time Machine?

Time Machine is Apple's built-in solution for backing up macOS. You can connect an external hard drive over USB or Thunderbolt (or FireWire, for older Macs) for a wired connection or over a network for a wireless connection. Time Machine backs up every hour, deleting older backups as the backup drive starts running out of space.
