I reported this earlier but it looked like resolved back then, but it comes back again. I have a couple of macs all running Big Sur, and if I left Rhino7 open in any of those computers, then the next day I found them crashed when the mode changed from light to dark… To reproduce, you can open Rhino with your mac os set automatically changes modes, and wait until tomorrow, then you find a crash report on the screen in the morning. Thanks,
