Apple Intelligence is now available on iPhone, iPad, and Mac!
I would like to trade in my MacBook Pro and buy a new MacBook Pro.
when I erase my Macintosh HD, the erase process failed due to the disk is still in use. Now it can’t be shutdown or restart.
Can I still trade in this laptop in this condition or do I need to take it to Apple to repair it first?
Many thanks!
MacBook Pro 13″, macOS 10.15
You must boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and erase from there. One can't erase the drive one is booted into. Then in the same Recovery volume window reinstall the system.

Erase fail for trade in
