The purpose of this EFI password is if it’s enabled, then the computer will stay protected, and the Mac will keep asking you to enter this EFI password every time you start up the Mac. If you don’t input the password, then you won’t be able to choose a startup from a storage device as well as not being able to get macOS Recovery or add any modifications.

-          macOS upgrade

-          Hard disc erasing

-          Mac computer restoring via Time Machine
