Submitted the patch, and I license the icon under the PSF contributor agreement. To make the icon, I used: (1) the default Apple folder icon as a starting point and (2) the Python icon from https://www.python.org/community/logos/ (but with modified colors). For (1), not sure if there are any copyright issues involved and if so how to get proper permission from Apple. I'm guessing the old icon also used the default Mac folder icon at the time. For (2), I defer to your expertise to find out the right people to contact to get it approved.
