When you execute the sudo rm -rf/* command in the terminal, you find that everything has been deleted, and restarting the computer displays the Apple icon and the progress flickering. Don't panic! Shut down first, press the power button and release it, and then press and hold the power button until the drive disk appears, which is a good solution.
If an exclamation point appears at this time, great, your stuff is gone! ! !
Are you panicking at this moment? When you execute this command, you should think about the consequences first, and it is best to have backup data.
This situation can only be solved by flashing the machine, and another computer is needed to flash the machine. If you can’t do it yourself, you can call the technician on Apple’s official website, and then make an appointment to go to the local Apple store. The technician will help you for free and give you more help. !
