Brainbit python demo does not work on macOS.
PFA screenshots of the error encountered while running the BrainbitDemo/main.py in neurosamples/python repository. Running this demo with python 3.11 on a macOS. 
It is claimed that python is supported in macOS but looks like the library isn't present for the same. This is the main place where the error is present, if you look at line 24, there is "add macos lib", which is probably where the problem is.
