Wiping Your MacBook Air Without Reinstalling macOS
After you’ve checked that your data is backed up to an external storage unit, you can start deleting anything from your MacBook Air’s internal storage. If you want to uninstall the computer rather than reinstall macOS, start by following these steps:
The steps below will fully wipe your MacBook’s internal storage unit, erasing all data and information.
- Start by turning off your Mac via the Apple menu or by pressing the power button on your keyboard once.
- Keep down the Command and R keys on your MacBook’s keyboard at the same time until your screen is fully turned off.
- R + Command
- Switch on your MacBook Air without letting go of any previous buttons.
- You should let go of the Command and R keys until you see the Apple logo or a spinning globe on the phone.
- Allow the device to enter Recovery Mode when it starts up. When you see the macOS utility window, continue.
- Select Disk Utility from the macOS utility window.
- Select Show All Devices from the View menu option. The drives connected to your computer are listed below the View menu button. Choose your primary drive, which includes Macintosh HD.
- Click the Erase button once your drive has been selected.
Leave all settings in the Erase window alone and press the Erase button. Restart your computer. Your computer will turn on with a blinking question mark in a folder icon if it has been successfully erased.
Additional macOS Installation Alternatives
When you boot up your Mac, pressing Command + R automatically installs the most recent version of macOS that has been installed on your computer.
When booting, however, two additional options are available:
- R + Option + Command
- The choice mentioned above will install the most recent version of macOS that is compatible with your MacBook Air.
- Option + Command + R (Shift + Option + Command + R)
The version of macOS that came with the Mac is installed with this option. If your MacBook Air is older, the nearest version that is still available will be installed.
