Important: Do not follow the steps below if your computer is a Mac with Apple silicon or an Intel-based Mac with the Apple T2 Security Chip. Instead, follow the steps in Erase your Mac.
Before you begin
Erasing your Mac removes all the information from it. Back up your Mac with Time Machine.
Make sure your Mac is connected to the internet.
If you’re reinstalling on a Mac laptop, plug in the power adapter.

In Disk Utility, select the volume you want to erase in the sidebar, then click Erase in the toolbar.
Type a name for the volume in the Name field, click the Format pop-up menu and choose APFS, then click Erase Volume Group.
When the erase process is complete, click Done, then choose Disk Utility > Quit Disk Utility.
