Recently I experienced some issues booting. I sent it to Apple they replaced the GPUs, Logic board, and a few cables. I got it back yesterday and it still is having issues booting correctly. The boot issues are the following, it boots perfectly fine into Windows 10. If I restart my computer and hold option, try booting into safe mode, or recovery I see nothing but a black screen. I never see the Apple logo, though I do hear the chime.
I found, however, if I plugin an external SSD that has macOS installed on it, when it boots into Windows and I select what I think is the same internal drive and I hold option on startup boot options are displayed. I see the two Mac volumes, the Windows volume, and then two Boot EFI volumes. If I select the internal boot volume, it works and loads totally fine. From here if I hit restart, it will go back to a black screen.
I ran disk utility to see if there was a problem with the internal Mac partion and it came up empty.
Any help would be greatly appreciated.
I'm wondering if I try installing Montrey if part of that process will be wiping out any corruptions there may be on the boot files.
Thank you all!
