This Library fix seems to only work if you’ve previously had Komodo installed. I’ve just installed Komodo on a (new to me) 2017 MBP 13" running BigSur; get the same error others have reported - but there is no Komodo folder in ~Library App Support, I’d guess because the app has never run.
Any suggestions? I used to use Komodo and loved it. Would be sad to move on to another editer…
