MacBook rapidly flashing prohibited sign, apple logo, and missing folder icon after restoring macOS on it. Reason for restoring was blank screen on start up. (2012 MacBook Pro)
The Macbook was working fine although sometimes it would shut down unexpectedly while sleeping (not sure it has anything to do with this) and reported a sleep/wake issue once started back up. Otherwise worked fine.
When I pulled it out of my bag one day it was shut down and when I started it it just showed a blank white screen. I then tried to boot into my second boot camp partition and it says disk error. So logically I put in a different drive that I know works. I went to recovery mode and did a clean install of macOS on it. But as it tried to install it it seemed to crash and it shows the apple logo, the prohibited logo, and the missing folder icon cycling between them and flashing rapidly. When I force shutdown and start again same thing happens. It will do this infinitely. When I remove the drive and start it it just shows the missing folder icon as it should normally.
What could the problem be and how can I get this working again?
thanks 🙂
