I not too long ago purchased a used MacBook Air 2012 And I wished to do a clear set up of the working system.
By restarting Restoration mode And erasing the arduous drive, I noticed two arduous drives “Macintosh HD” and “Macintosh HD – Information”.
When attempting to erase the Macintosh HDThere was an error “The amount in disk2s5 couldn’t be disassembled as a result of it’s in use by course of 659 (keextche) couldn’t disassemble the disc (-6988) that failed the operation“
I couldn’t begin Secure mode. I could not begin in Restoration mode Default entry Web restoration modeAt first I had “Pkdownload Error 2“He deleted the items typically extra and obtained”You possibly can’t obtain the extra elements obligatory to put in mac os x“When attempting to put in the restoration mode.
I made a decision to make a USB begin unit from a backup file “Mac OS X 10.7 Lion Set up DVD.iso“, utilizing a MacBook Professional 2019 and terminal and the discover:
diskutil unmountDisk /dev/disk3
sudo dd if="/Volumes/DriveName/10.7-Lion/Mac OS X 10.7 Lion Set up DVD.iso" of=/dev/disk3 bs=1m standing=progress
I adopted these directions to disregard the property within the unit, however now when I attempt to begin from the USB unit, I press the choice, the meals, I write the WiFi password and instantly I get a forbidden signal 🚫.
Different issues I attempted:
1-units usually are not faulty as a result of First Public Companies Help It doesn’t return errors.
2-states the right date in Terminal (After having a sense that the interior clock was fallacious)
Is Macbook air broken or how can I do the brand new set up?
