Hi, we implemented some changes which require a fix from the user end temporarily while we work to update our tools to support these changes. The solution is to make the gmod executable run again by using the following command, then running the game as usual:

chmod +x $HOME/Library/Application\ Support/Steam/steamapps/common/GarrysMod/GarrysMod_Signed.app/Contents/MacOS/gmod

if you're running GMod from an external drive, this command may need to be modified to reflect that.
