This approach usually doesn't give me any problems, but I have run into one today, and it's quite a curious issue.
If I rip from the original disc or the created ISO on my Windows machine (ISO can be located anywhere on the network, it doesn't need to be local), MakeMKV rips perfectly, with no errors.
If however I rip from the ISO image on my Mac (again, doesn't matter where the ISO image is located), MakeMKV detects numerous sync errors that it then tries to correct; these are simply not there on when I'm using MakeMKV on the Windows machine.
I've tried creating the back up image several times, and repeated the MakeMKV rips on the same ISO image several times with completely repeatable results.
The only difference that I can tell between the Mac and PC (besides the obvious), is that I'm using the latest Mac version of MakeMKV (v1.8.7), whereas I'm still using the slightly older (v.1.8.6) version on the PC.
See below for a log of the AV Sync issues on Mac v1.8.7 MakeMKV:
