Erasing your Mac and resetting it to factory settings can be an effective solution if you are experiencing performance issues, selling your Mac, or simply want to start all over again. To reset your Mac to factory settings, you can use either the Erase Assistant or Disk Utility. Newer Macs have the Erase Assistant, while the older Intel-based models rely on Disk Utility.
In this guide, I will demonstrate the steps for both. But first, it is crucial to review the precautions you should take before resetting.
Things to do before resetting your Mac
Before you make the final call to erase your Mac, I strongly advise you to take the following steps:
- Backup Mac data: Backing up your MacBook and ensuring that all important files, documents, and media are safely backed up is a critical first step, as it prevents data loss throughout your MacBook Pro or Air.
- Disable FileVault: If you have decided to reset your Mac, you must disable FileVault as one of the necessary steps.
To do so on macOS Sonoma/Ventura, go to System Settings → then head to Privacy & Security → Scroll down to Fire Vault → Select Turn Off → enter your Mac’s password → Click Unlock → finally, select Turn Off Encryption to finish the process. - Cancel or transfer AppleCare: If your Mac is currently covered by AppleCare, you must consider the process of transferring the AppleCare plan. This is an important step that must be taken to ensure that your new device remains covered by AppleCare.
- Finally, plug your Mac in for a charge and ensure you have a stable internet connection to complete the factory resetting process.

Note: During the procedures outlined above, you might need to:

Now, wait for the Mac to restart and then follow the onscreen instructions. After that, connect to a Wi-Fi network → select Exit to Recovery Utilities. Now, if you want to reinstall the macOS, you can follow the steps illustrated below.
