Important: This process erases all of your data. Make sure you have an up-to-date backup of your Mac.
Launch Apple Configurator
on your iPhone.If you’re adding a Mac laptop, plug it into a power source so it doesn’t go to sleep during the process.
If the Mac is connecting to the internet using Ethernet, plug in all necessary cables and adapters.

If your Mac has macOS 13 or later: Choose Apple menu
> System Settings, click General 
, click Transfer or Reset, then click Erase All Content and Settings.If your Mac has macOS 12 or earlier: Choose Apple menu
> System Preferences, then in the menu bar, choose System Preferences > Erase All Content and Settings.
In Erase Assistant, enter your administrator information.
Review items that Erase Assistant removes in addition to your content and settings.
If your Mac has multiple user accounts, click the arrow next to your account name to review the items.
Click Continue, then follow the onscreen instructions.
Note: If you have a modified version of macOS, Erase Assistant can’t erase your Mac and displays an alert indicating you need to first reinstall macOS. For more information, see Erase and reinstall macOS.
