Results below with macOS 10.13.3 including the Apple Supplementary Update. See Nikon D850 'Focus Shift shooting' feature for Easy Focus Stacking. This stack uses 20 16-bit 45-megapixel images from the Nikon D850. Some code optimization is needed, since Helicon Focus is able to use all 18 cores quite well. The gain from CPU cores is modest, the 2017 iMac 5K takes only 32% longer. Since I almost always stack with both PMAX and DMAP methods, this test totals the time of the two. I use Zerene Stacker heavily for focus stacking and it takes minutes to do some stacks, so speed here matters a lot to me. Not sure which Mac to get or how to configure it? Consult with MPG.
