In short, I have not been able to use LOPS well yet on the Mac. The viewport looses focus and after a while everything gets slower and slower so you have to restart H. It also crashes a lot. Not that other parts work great either but the LOPS part is completely unusable.
Am I having a bad experience all by my own? Or is this the way it is on Mac?

(I am testing this with 19.455 on the latest M1 Max macs since they are lovely laptops and almost all other software works like a charm. Main WS is a windows/linux machine so please don't go "platform war" on me.)

get in contact with SESI:

It's the same with me on Windows 10 and OpenSUSE. /stage is basically unusable. But everyone else seems to not have problems with it so I don't know what's going on.

Anyway you should contact SideFX.
