Won't load any maps.

I know many many people are having problems, but I can’t find any solutions and I haven’t been able to play for 3 weeks. My Gmod (I play on Macintosh) won’t load any maps, instead it’ll just return to the main menu after loading the map. I’ve tried uninstalling all of my addons and the problem still continues to happen. Does anyone have any ideas?

this happened a while ago. Your garry’s mod is fully updated right?

Delete local content. The go into the steamapps then delete garrysmod from there (If it is still there). After that download it again.

Alright, I will try this one. Also, I am currently updated to the newest version.
