Using Python in Grasshopper. Solution exception: No module named AppKit


I am using the Mac version of Rhino/Grasshopper.
I am trying to import a module for the using Python inside Grasshopper.
When running the script, I receive the following error.
I have AppKit installed. I’ve even tried saving AppKit and PyObjC in a separate directory and using sys.path.append to access it.

Any idea what I am doing wrong or can try?
