How to Reset Your Mac to Factory Settings

Resetting your Mac to its factory settings can be a useful troubleshooting step or a necessary action before selling or giving away your device. By resetting your Mac, you can ensure that all your personal data, applications, and settings are securely erased, returning it to the state it was in when you first unboxed it.

Backup Your Data

Before proceeding with a factory reset, it is crucial to back up all your important files and data. This ensures that you don’t lose any valuable information during the process.

To back up your data:

  • Time Machine: Connect an external hard drive and use Apple’s built-in Time Machine feature to create a full backup of your Mac.
  • iCloud: Use iCloud to sync and backup important files such as documents, photos, and contacts.
  • External Storage: Manually copy important files onto an external hard drive or USB flash drive.

Create a Bootable macOS Installer

In order to reset your Mac, you’ll need a bootable macOS installer. Follow these steps:

  1. Download macOS: Visit the App Store and search for the latest version of macOS. Click on “Get” or “Download” to start the download process.
  2. Create Bootable USB Drive: Once the download is complete, connect a USB flash drive with at least 12GB of storage. Open “Terminal” application (located in Applications > Utilities) and type in the following command:

$ sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

Note: Replace “Mojave” with the name of the macOS version you downloaded, and “Untitled” with the name of your USB drive.

Restart Your Mac in Recovery Mode

After creating a bootable macOS installer, you can now proceed to reset your Mac:

  1. Shut Down Your Mac: Click on the Apple menu and choose “Shut Down”.
  2. Enter Recovery Mode: Press and hold the Command + R keys while turning on your Mac. Keep holding until you see the Apple logo or a spinning globe.
  3. Select Disk Utility: Once in Recovery Mode, select “Disk Utility” from the macOS Utilities window.
  4. Erase Your Mac’s Hard Drive: In Disk Utility, select your main hard drive (usually named “Macintosh HD”) and click on the “Erase” tab.

    Choose a format (APFS or Mac OS Extended) and click “Erase”. Confirm your action when prompted.

  5. Reinstall macOS: After erasing your hard drive, exit Disk Utility and choose “Reinstall macOS” from the Utilities window. Follow the on-screen instructions to reinstall a fresh copy of macOS.

Note: Depending on your internet connection speed, this process may take some time.

Restore Your Data

Once you’ve completed the factory reset and reinstalled macOS, it’s time to restore your data:

  • Time Machine: If you backed up your data using Time Machine, connect the external hard drive and follow the prompts to restore your files.
  • iCloud: If you used iCloud to back up your files, sign in with your Apple ID and enable iCloud Drive, Photos, and other relevant options to sync your data back to your Mac.
  • External Storage: Manually copy the files from your external hard drive or USB flash drive back onto your Mac.

By following these steps, you can easily reset your Mac to its factory settings and ensure that it is ready for a fresh start or a new owner. Remember to always back up your data before performing any major changes to avoid data loss!
