Spawn Menu Not Opening

So, I’ve finally gotten around to playing Gmod13, and whenever I press Q, the spawn menu doesn’t open. Instead, I get some message saying, “Something is causing script errors.” I’ve done some research, and other people have had this problem, but no one seems to have an actual solution for it. Has anyone else had or solved this problem?
Also, I run a Mac. Not sure if that might be part of the problem or not.
Anyway, any help would be appreciated.

MacOS version of Garry’s Mod is broken, how you even managed to start the game is beyond me.

It seems to be working fine, except for the whole spawn menu thing.
