The issues above all appear to be for the same issue I am having. They seem to either not have been addressed as of yet, or marked as duplicates and closed. I was hoping it might be addressed.

STEPS TAKEN:

1. Verifying game cache for Garry's Mod
2. Verifying game cache for Counter Strike: Source
3. Completely "cleaning", or removing all associated files for both Garry's Mod, Counter Strike: Source
4. Disabling steam cloud features for both Garry's Mod and Counter Strike: Source
5. Opting into beta versions of Garry's Mod (after cleaning, and reinstalling)
6. Restarting computer
7. Copying the hl2_osx executable file from the Counter Strike: Source folder into Garry's Mod
8. Starting the game with different combinations of either one or both of the arguments, "-autoconfig", "-sw"
9. Deleting steam's appcache folder
10. Disabling system firewall
11. Disabling OSX "Gatekeeper"
