It did work on my old Intel Mac.

SOS does not support the current target architecture 'arm64' (0xaa64). A 32 bit target may require a 32 bit debugger or vice versa. In general, try to use the same bitness for the debugger and target process.

Can you enable logging with logging enable? Do commands like runtimes, sosstatus or dumpheap -stat work? It is almost like x64 version of libsos.dylib is being loaded (the one under osx-x64 instead of osx-arm64). The only way I could see that happening is if the SDK/runtime installed is x64 instead of arm64. Can you make sure the right runtime architecture is installed? dotnet --info should display that. You might have to reinstall the SDK and then dotnet-dump.
You were right. I did have x64 sdk installed for whatever reason. I deleted everything and it is better.

Any thoughts on the GetFrameContext failed: 80070057 @mikem8361 ? It would be really nice to get stack and dump objects.
That's probably dotnet/runtime#104816 - a relatively recent regression under investigation that was caused by dotnet/runtime@9528c15 this is .NET 8, so my point is moot.
Sorry, I didn't actually look at the clrstack output. I saw that you said everything was ok and stopped reading.
I think we need a M3 to repro this.
