How do I recover data on macOS High Sierra when hard drive won't boot?' macOS 10. I've tried to Mount EFI(from both USB and EFI-drive) and copy them into the disk I installed Mac OS on.
There is certainly more than one way to get a dualboot system running. This patch maker for macOS High Sierra does NOT work on my Mac mini 2007, A1176, Core 2 Duo 1.
