I was wondering If anyone else had managed to get Processing working on the new macOS beta or if I’m just doing something wrong with my installation or something like that.  
FIXED: in developer beta 5 it works

I haven’t tried it, no. What error(s) are you getting?

It has been fixed in dev beta 5 I just can’t delete my post what was happening was it would partially open to the loading screen and then crash.
