I goofed. I fell for it again and upgraded my OS and destroyed GEM. But this time I can't see any solution to getting it running again.

Anyone had luck hacking your way through getting GEM running on Big Sur?

Just want to do cool things again.

Yeah, my multimedia exam is screwed for one student because of this too.

I'd asked on github and received this suggestion:

i don't really know, but she could try changing the windowing backend, by changing the gemdefaultwindow.pd abstraction in the Gem/-folder and replacing the [gemmacoswindow] (or whatever is there) to one of the other gem*window options installed on your system. (just look out for any externals (.pd_darwin,...) in the Gem/-folder that match the gem*window pattern).
possibly good choices are: [gemglfw3window], [gemglutwindow].

FWIW this is the nail in Gem's coffin for me. Too risky to try to keep it working for a room of 40-50 students.

ah yes! this did it. [gemglutwindow] is working!
Thanks so much.

I tried this solution few months ago under Catalina, but I had a very big choppy animation... So I switched to ofelia and never had any problem since.
