Flashing Question Mark, No Keyboard Inputs Work
Hey guys, I got my MacBook and installed Catalina with the dosdude1 patcher but was having issues so I wanted to go back to High Sierra. I went to try Command + R and it didn’t work. I also tried internet recovery, nada. I disconnected everything including the battery etc and that make no change, SMC reset did nothing either. When holding Alt/Option no boot devices show up. I completely wiped the HDD (fully functional along with the HDD cable btw) and tried installing using a USB, still has a flashing question mark. I installed the installer on different computers, different MacOS versions, USB’s etc. Nothing works. Any ideas? Thanks
Ist dies eine gute Frage?
