 | Mac Pro 4.1 (2009) + Opencore Patcher 0.6.8 M.2 SSD 500GB (2 containers: 250GB High Sierra + 250GB Monterey) Lately I've had several warnings in Monterey about hash mismatch detected volume disk1s5. macOS should be reinstalled on this volume. So I formatted the drive and reinstalled Monterey. At the end I installed Opencore on the EFI and Monterey everything works correctly after restoring my Time Machine backup but to my surprise High Sierra does not start, with the forbidden symbol appearing. I booted into recovery mode to run First Aid in Disk Utility and it said everything was correct. Still not starting. As seen in the screenshot, High Sierra exists and I can access all the files including the Finder and Downloads files of both my user and my girl: I reinstalled Opencore on the EFI but High Sierra still shows the forbidden symbol. Is there a way to modify something to boot High Sierra? Any suggestions would be welcome. P.S. I have a copy of Time Machine made in Monterey and although inside I see that there is a folder for Monterey and another for High Sierra, I think that if I reinstall High Sierra from scratch I will not be able to recover the copy as it is made in a more modern version of Time Machine . Thanks in advance. [link] [comments] |
