So whilst trying to reinstall Mac OS Big Sur on my new MacBook Pro M1, I deleted the volume from the Apple SSD and now it won’t let me install Mac OS. Whenever I try to my drive won’t even show up. I’ve spent hours trying to find a solution and apparently I need to erase the drive, but it’s not letting me. I keep getting “couldn’t open device error 69877). I don’t know what to do at this point. Can someone please help me?
