Recent macOS no longer suggest doing a clean install or rather is no longer needed when getting rid of unused files. We’ll go further about it later.
The most common method to clean install Mac is to make a bootable copy of the macOS installer on a USB drive. You will then need to reformat your drive before installing the bootable copy to Mac. You can also perform a clean install using the Recovery Method.
Reinstalling macOS
- To begin the installation, Enter macOS Recovery.
- Select Reinstall macOS from the Utilities Window.
- Click Continue and follow the onscreen instructions.
- Enter the password you use to log in to your Mac if the installer asks to unlock your disk.
- If your disk is not detected, or it can't install on your computer or volume, erase your disk first.
- Choose Macintosh HD.
- Allow the installation to complete. Avoid putting it to sleep or closing its lid.
Your Mac might restart several times, and your screen might appear empty for minutes at a time. Complete the setup once the setup assistant appears.
Other Mac Clean Install Option
- If your Mac is intel-based, use the Shift-Option-Command-R during startup. Or you can use Option-Command-R during the startup.
- If you have obliterated the entire startup disk, only the macOS that came with your Mac will be your option, or the closest version available.
You can also use these methods to install macOS if the macOS is compatible with your Mac:
- Download and install the latest macOS or an earlier macOS from the AppStore.
- Use a USB flash drive or another secondary volume and create a bootable installer.
2.1 Why Mac Clean Installer Is No Longer Needed
macOS Big Sur now has its own volume called Sealed System Volume. This seal is kept in the T2 chip of the more recent Intel Macs or inside the Secure Enclave of the Apple M1/M2. This means that macOS itself cannot be altered by any software that you install as a user.
A Mac clean installer no longer applies because no information is carried over. All segments are inspected after installation, then signed, and finally, the entire system is sealed. The seal is your guarantee that nothing is wrong with your system.
