With a fresh installation of Blender and BlenderBIM, when attempting to activate the BlenderBIM add-on I get the following error:

Any help resolving this would be greatly appreciated.

Update: There is a masos arm build, see comment from Moult below

Old Post:

I see only a blenderbim mac arm build for python 3.9, so i think you need to install a blender arm build version that has python 3.9 or you can just install the newstest blender intel build with the blenderbim macos build that has 3.10, since apple has the translation layer rosetta

We do support MacOS ARM, are you sure you downloaded blenderbim-230811-py310-macosm1.zip?

Oh i did not see it in the list ?

@Martin156131 and @Moult, thank you for the feedback. This was indeed an error on my part; I did not download the ARM build (labeled "M1" on the downloads page). After downloading the correct build, I was able to activate it. Thank you for the guidance.
