Hello!
That’s suspiciously similar to the number of errors I’m getting on my intel processor mac. I think there’s something going on with Brian and cython (and maybe some other things) on mac.
The good news is if you set:
prefs.codegen.target = 'numpy'
[more info here]
you should be able to run most Brian code! (i haven’t run into any issues outside the test suite so far)
The bad news is this will likely be slower than if Brian had access to Cython.
My guess is your problems overlap with those discussed [here] in which case it might be good to continue the discussion there
