Are you experiencing issues with your Mac Mini and need to start fresh? A factory reset can help restore your device to its original state, eliminating any software or performance problems you may be facing. In this tutorial, we will guide you through the process of factory resetting a Mac Mini.

Backup Your Data

Before proceeding with a factory reset, it is essential to back up all your important data. This step ensures that you won’t lose any valuable files during the reset process. You can use Time Machine or any other backup method of your choice.

Disconnect External Devices

Next, disconnect all external devices such as USB drives, printers, and speakers from your Mac Mini. This step prevents any interference during the factory reset process.

Accessing Recovery Mode

To begin the factory reset process, we need to access the Recovery Mode on your Mac Mini. Follow these steps:

  • Shut down your Mac Mini by choosing Apple Menu > Shut Down.
  • Press and hold the Command (⌘), Option (⌥), and R keys.
  • Keep holding these keys until you see the Apple logo or a spinning globe.
  • Select a language, and then click on the ‘Utilities’ menu in the top menu bar.
  • Select ‘Disk Utility’.

Erase Your Disk

To proceed with the factory reset, we will erase everything on your Mac Mini’s disk. Follow these steps:

  • In Disk Utility, select your Mac Mini’s startup disk.
  • Click on the ‘Erase’ tab.
  • Choose a name for your disk.
  • Select a format – we recommend choosing ‘APFS’ for macOS High Sierra and later versions, or ‘Mac OS Extended (Journaled)’ for earlier versions.
  • Click on the ‘Erase’ button to begin the disk erasure process.

Reinstall macOS

After erasing your disk, you will need to reinstall macOS. Follow these steps:

  • In Disk Utility, click on the ‘Disk Utility’ menu in the top menu bar.
  • Select ‘Quit Disk Utility’.
  • Select ‘Reinstall macOS’.
  • Follow the on-screen instructions to complete the reinstallation process.

Restore Your Data

Once you have completed the factory reset and reinstalled macOS, it’s time to restore your data from the backup. Follow these steps:

  • If you used Time Machine for backup:
    • Connect your Time Machine backup drive.
    • Follow the prompts to restore your files, applications, and settings.

    If you used another backup method, simply copy your files back to your Mac Mini.


Congratulations! You have successfully factory reset your Mac Mini.

This process ensures a clean start, resolving any software or performance issues you may have encountered. Remember to regularly back up your data to prevent any future data loss.
