I've been following this thread for several months now, as I've been using DVDFab on a PC for several years now. Out of interest - following SeattleChris' comment above - I installed it on my m1 macbook air. It appears that the kernel extension (which I believe is what sits between the drive itself and the main application and does the decryption) is a universal binary:

Seeing this, I tried ripping some of my blu-ray discs and - although the main DVDFab program shows as being "Intel" Kind (and therefore relying on Rosetta 2), all completed perfectly - which is more than I can say for EaseFab ... out of 5 discs, one failed to rip and two made the laptop reboot when opening the disc at the start of the rip :confused:
On the basis of that, I've now added the mac platform licence - hopefully the programmers can develop a native m1/ARM chip version of DVDFab before Apple pull the plug on Rosetta 2 :)
