My new (2019) i7 quad core Mac running Catalina, 4.3 Ghz clock with 40Gb of RAM Registered the same set in 13 minutes (12:56 to be exact)

Stacking times were about 8 and 6 minutes respectively, so sure, not a half hour for the Win machine (23 mins) and 19 mins for the new Mac.

The 6720 x 4480 pixel raw files I'd suggest are the bottle-neck.

I'd be interested to hear from anyone running the 60Mp Sony chip to see how long it takes to register 30-40 frames.
Then Iím really glad I only have an old school 9mp CCD that generates reasonable 18MB files!
