Step-by-Step Guide: Factory Resetting Your MacBook via Disk Utility
Before you begin, back up any essential data you want to keep. This step is crucial as the process will erase everything on your hard drive. Once you've completed your backup, follow these steps:
Step 1: Boot into macOS Recovery Mode
- Shut down your MacBook completely.
- Turn it on and immediately press and hold the Command (⌘) + R keys. Hold them until you see the Apple logo or a spinning globe. This will boot your Mac into Recovery Mode.
Step 2: Access Disk Utility
- Once in Recovery Mode, you'll see a window with several options. Select Disk Utility and click Continue.
Step 3: Select Your Startup Disk
- In Disk Utility, you'll see a list of drives. Carefully identify your startup disk (usually named Macintosh HD or similar). Make absolutely sure you select the correct drive, as erasing the wrong one will lead to data loss.
Step 4: Erase Your Startup Disk
- Select the startup disk.
- Click the Erase tab at the top of the window.
- Choose APFS (Apple's file system) as the Format. If your Mac is older and uses a different file system, choose the appropriate one.
- Give your drive a name (e.g., Macintosh HD).
- Click Erase. This process will take some time depending on your hard drive size.
Step 5: Quit Disk Utility and Reinstall macOS
- Once the erase process is complete, quit Disk Utility.
- Back on the macOS Utilities window, select Reinstall macOS. This will reinstall a fresh copy of the operating system.
- Follow the on-screen instructions to complete the installation.
Troubleshooting Common Issues
- Can't boot into Recovery Mode: Try holding down the power button for several seconds to force a shutdown before attempting again.
- Disk Utility not showing your startup disk: Make sure your MacBook is connected to power. If the problem persists, you may need further assistance from Apple Support.
- Erase process takes too long: This is normal, especially for larger hard drives. Avoid interrupting the process.
Final Thoughts: A Clean Slate for Your MacBook
