1. Erase Your Mac Using ‘Erase All Content and Settings’
(For M1/M2 Macs)
If you have a Mac with an M1, M2, or T2 chip and it runs macOS Monterey or later, you can use the built-in Erase All Content and Settings feature to factory reset it. This method is simple, fast, and eliminates many manual steps. Here’s how you can do it:
- Click the Apple menu in the top-left corner of your screen.
- Go to System Settings and click General.
- Scroll down and select Transfer or Reset.
- Tap Erase All Content and Settings.
- Enter your admin password when prompted and click Unlock.
- Follow the on-screen instructions to confirm the erase process.
- After the reset, your Mac will restart automatically.
Once it restarts, you’ll see the setup screen. Here, you can select your preferred language, connect to Wi-Fi, and follow the setup instructions to get your Mac running again.
3. Erase Your Mac Using Recovery Mode
(For Intel Macs)
If your Mac doesn’t support the Erase All Content and Settings feature, you’ll need to reset it using Recovery Mode. This method requires a few extra steps, especially for older Intel-based Macs.
Step 1: Sign Out of Your Accounts
Before resetting, log out of all your accounts to ensure no data is tied to your Mac. Here’s what you need to do:
- Find My Mac:
- Open System Settings and select your name under Apple ID.
- Go to the Find My Mac section and turn it off.
- iCloud:
- In the same Apple ID section, sign out of iCloud. If prompted, choose whether to keep a local copy of your data (this isn’t necessary if you’ve backed it up elsewhere).
- iMessage:
- Open the Messages app.
- Click Messages > Settings/Preferences > iMessage and select Sign Out.
- iTunes and Music:
- Open the Music app.
- Go to Account > Authorisations > De-authorise this computer.
- Then, log out of your account.
- Other Accounts (e.g., TV):
- Open the TV app and log out of your account similarly.

Step 2: Restart Your Mac in Recovery Mode
Recovery Mode allows you to erase the disk safely and reinstall macOS.
- Shut down your Mac.
- Press and hold Command ⌘ + R, then press the Power button to turn on your Mac.
- Release the keys when you see the macOS Utilities screen or the Apple logo.
Step 3: Erase Your Startup Disk
Now that you’re in Recovery Mode, you can erase the startup disk:
- In the macOS Utilities window, select Disk Utility and click Continue.
- From the left-hand menu, select your startup disk (usually labeled “Macintosh HD”).
- Click the Erase button in the toolbar.
- Choose the format:
- APFS for newer macOS versions.
- Mac OS Extended (Journaled) for older macOS versions.
- Click Erase to wipe the disk.
Once the process is complete, close Disk Utility to return to the macOS Utilities window.
💡 Tip: Make sure you have backed up all important data, as this process permanently deletes everything on the disk.
Step 4: Reinstall macOS
The next step is reinstalling macOS. Here are the steps to reinstall macOS using Recovery Mode:
- Connect your MacBook to the internet.
- Turn off your Mac and turn it back on while holding down the Command ⌘ + R keys on your keyboard. Keep holding the keys until the Apple logo appears.
- This will boot your Mac into the Recovery Mode. Once it loads, select Reinstall macOS and click Continue.
- Follow the on-screen instructions to select your startup disk and begin the reinstallation process.
- After the installation, your Mac will restart and display the Setup Assistant. Follow the on-screen instructions to set up your Mac.
- You should have a fresh macOS installation after completing the setup process.
This concludes the process to factory reset your MacBook.
