A while back I reported a problem I was having on my old 2013 Mac Pro where Metashape would cause my entire Mac to completely freeze and I had to do a force reboot. This would happen about 60% of the time it would do a depth map generation pass. I was told that it was probably because of the low VRAM on that machine, so I should try reducing the tile size to 512 with a parameter tweak and see what happened. That reduced the system freezing to about 5% which was a much more tolerable occurrence.
Now, on my new MacBook Pro with 64Gigs of RAM/VRAM I still get the occasional system freezes during Depth Map generation. I'm back to using the default 2048 tile size, but it still happens around 1 in 40 times, so rare, but still every week.
This is with Metashape 1.7.3. I can't use the later versions because 1.7.3 is the last version that builds meshes from Depth Maps properly.
