Sorry to hear that. I have still not solved this puzzle, but I do have a workaround:
- Because I have several other Hacks and Macs, I do the following:
- Clone the NVMe SSD to a SATA SSD mounted in an external USB 3.0 enclosure.
- Connect the SATA SSD to another Hackintosh(or Mac).
- Boot the Hack using its own EFI folder.
- From the OpenCore Picker, boot the external SATA SSD.
- Login to macOS and perform in-place update through System Preferences --> Software Update.
- Shutdown the system and remove the SATA SSD.
- Connect the SATA SSD to the original Hackintosh.
- Boot the Hack and select the SATA SSD.
- Login to macOS.
- Make sure everything is okay.
- Then clone the SATA SSD to the internal NVMe SSD.
- Always good to make a backup clone of the NVMe SSD before doing this.
