Hi all,
was having a lot of the same issues.
Mac Studio M1 max here.
I would get a complete freeze up of OS, no mouse or keyboard input and then the whole system would go black, eventually Id be prompted to enter my login password (like it was just in sleep mode)
after reading through other posts It seems to be something with the video out and the monitor. I know that Unreal is constantly updating screen, even if there is no activity… so maybe it has to do with the RHI abstraction layer between openGL / metal and the screen refresh is going haywire… Anyhow, It made me try a few things… I am using an LG monitor via HDMI out on the mac studio. not the mac monitor.
one fix (kind of) was the moment the screen froze (and mouse and keyboard) input, I would turn my monitor off, and then back on. and voila, it worked. unfortunately, each time I did this, the software was running worse and worse and worse. by the 4th or 5th time of doing the monitor off and on, the unreal editor window was flickering quite bad, and everything had a noticeable lag.
Im not sure if this is an issue that will be completely resolved with optimization based on my limited understanding of OpenGL, metal, and DIRECTX
update:
i updated MAC OS to 12.5 and I havnt had the issue since.
I do notice a slight difference in responsiveness between Unreal and Unity, so it might just be a deeper issue for MAC users. TIME WILL TELL.
It seems like divide between technology paths might be growing…
At this point… If you are looking for a new RIG specifically for working with UE5. I would say MAC Studio is not it. Hopefully that will change.
