How to Factory Reset a Mac
The following steps will guide you through wiping and reinstalling macOS. Whether you’re preparing to sell your Mac or want a clean start, this walkthrough covers everything—without any tech jargon.
Step 1: Back Up Your Data
Before you erase anything, create a full backup using Time Machine.
Time needed: 30 minutes
- Connect an external drive.
- Go to System Settings > General > Time Machine.
- Select your backup disk and choose “Back Up Now.”
This ensures you won’t lose important files when resetting the Mac.
Step 2: Sign Out of iCloud and Apple Services
You need to unlink your Apple ID to prevent issues for the next user.
- Open System Settings > [Your Name] > iCloud.
- Scroll down and click Sign Out.
- Enter your Apple ID password to confirm.
This removes Activation Lock and disconnects your Mac from your account.
Step 3: Erase the Disk
Now you’re ready to wipe the internal drive.
- Turn off your Mac.
- Press and hold Power until Loading startup options appears.
- Select Options, then click Continue.
- In macOS Recovery, go to Disk Utility.
- Choose your main internal disk (usually “Macintosh HD”).
- Click Erase, select APFS, and confirm.
This step fully erases your Mac’s storage and prepares it for a fresh install.
Step 4: Reinstall macOS
Once the disk is clean, reinstall the system.
- Return to the macOS Recovery main menu.
- Choose Reinstall macOS.
- Follow the prompts to complete the installation.
This gives you a clean copy of macOS, ready for setup.
Step 5: Set Up the Mac for a New User or Sale
Once installation finishes, your Mac will restart.
- If you’re keeping the Mac, complete the setup assistant.
- If you’re giving it away, press Command + Q and shut down.
This leaves the Mac at the welcome screen, ready for its next owner.
