  • That's a hardware issue - it could be the GPU or the screen itself. What happens if you continue to boot? Also, your upgrade won't have anything to do with it (the screen you're showing is the EFI boot screen and not macOS); it's just a coincidence the two happened together. – Allan Jan 13 at 18:27
  • Thanks for the response but I didn’t want to believe it’s hardware issues cos i have an external windows bootable hard drive in it before restating it. – UpIn Jan 13 at 18:53
  • I'm not sure what you're saying... – Allan Jan 13 at 20:05
  • I need a way to fix the efi boot error maybe there might be luck rather than coupling the error just a suggestion. Because i recently checked the hard drive with disk Utility and everything seems okay. – UpIn Jan 13 at 20:53
  • What you're seeing is not an "error." It's a failure. – Allan Jan 13 at 20:56
