So this week I dropped a whopping £4,200 on a sparkly new Mac Studio Ultra, in a desperate attempt to claw back some time waiting for builds.

Every version I’ve tried, both Intel and Apple Silicon, crash within seconds of opening. Like, system reboot crash. I grabbed a crash log and will paste it below, but it seems Unity have issues generally with stability on AS…?

What version(s) of Unity?
New and empty project, or existing one?

Although issues with Mx Apple chips are not unheard of, with a completely new system behaving this way I wouldn’t totally rule out defective hardware. Unity may be the first app that’s actually putting a load on the system. Try to see if you encounter other issues with demanding software and run a system check (OS X has something for this built-in via boot hotkeys).

I think Unity requires a good Nvidia or AMD graphics card and Mac computers don’t have it.

Just to nip this in the bud, this is inane and false. The Unity editor runs perfectly fine on GPUs from Intel and Apple, including my M1 Max.

The M2 Ultra is very new, but I’d be surprised if it was different enough from M2 Max for this to be a hardware support issue specifically with the CPU in Unity. Looking at the crash log, I would disconnect any external peripherals and stress-test my RAM as a first step to triage.

My M1 MacMini has had zero trouble running Unity. It’s not a fast experience because I deliberately went with a model that had the base M1 to have a min spec machine for testing but it’s not at all the case that it’s being held back by being custom silicon.

Thanks for the info. Could we connect an external graphics card to a Mac with M1 chip, to run Unreal Engine 5 smoothly?

Could we run Unreal Engine 5 on an M1 Mac Mini connected to an external graphics card?

I don’t know if there are any complexities with the external graphics card, but you can for sure run it without an external graphics card.

Apple Silicon has no support for external graphics cards.

Multiple Unity versions, multiple existing projects across multiple targets. Tried projects copied over from an pc, with library folder etc and projects with only source pulled from GitHub. Always seems to happen once you try and interact with the editor.

Do you have any external devices connected? Kernel panics are usually 3rd party driver-related. The next most likely culprit is RAM, which might also be indicated by the “mismatched swapID’s” error. If you really suspect the CPU, I’d head to a macOS community like MacRumors (or, if it was any other time, Reddit) to find other new M2 Ultra owners who would be willing to install Unity for a second data point. If you have an Apple Store nearby, they might help you try it on another machine, as well.

And empty project?

13

Only got usb keyboard, mouse a mic and a webcam attached. So doubt it’s those. And again nothing else has crashed once. I’ll try empty project :slight_smile:

14

I don’t have kernel panics, but I had a lot of regular crashes before I added “-force-gfx-st” at the project command line. Maybe it will help?

15

Can you explain how to do this?

want to try. Many problems with m2 Max

It disables multithreading for the editor.

My M1 MAX is a rocket with no problems.

Just to add to what others have said, I have an M2Max/38/96 and have zero problems like that. I will admit I would have hoped build times/compile time would have been crazy fast… not. The are faster, but not over the top. But no hangs / crashes (yet)

Do you use Rider? I’ve got almost exactly the same as you, and have noticed intensely faster operation of Rider. As though their Silicon coding has transformed it from a Java app to a C app, it’s stunningly fast, and finally feels more like using Sublime in terms of performance and responsiveness. Where I’d always put up with all the little hangs and hitches of Rider because of its features, now it’s all win.

OK, new project, 3D template, 2022.3.2f1. I got as far as opening project settings before it kernel panicked.

Unplugged my webcam and microphone, fired up the empty project again, barely lasted 5 seconds before rebooting.
