Okay, this is a weird one.
I have two monitors, one is an MSI MPG271QX OLED with a max (default) refresh rate of 360Hz. IF the monitor is at 360Hz and I either start the FGU updater on that monitor, or move it to the monitor while it is updating, my system gets a kernel panic and crashes. My fix has been to drop my monitor to 240Hz (or lower) refresh rate as nothing I do on the Mac really requires 360.

However, as more monitors are moving to the higher refresh rate, I thought I would make you aware of it, especially if others are suffering from this issue without knowing why. I'm also concerned that the Mac could reset the refresh rate back to default causing a potential crash if I'm not aware.

I am currently running
Apple M3 Max
macOS 16.6

There's nothing that we are doing that would cause that; and for most operating systems, a kernel panic/crash is at the driver level. My guess is that the Unity engine is making a call that interacts poorly with your driver. Unfortunately, it's not anything that we're doing specifically in the program, as the updater is running all Unity engine standard UI and nothing graphics specific. Also, we're not getting any other reports of Mac updater crashes on OS 16, and

So, we don't have any way to recreate or track down an issue like that. I would make sure your Mac OS and graphics driver are up to date to start with.
