I tried to download an addon to Gmod. I did it as I read on a web site, yet the addon will not appear on Gmod! I moved the folder with the addon to Users>username>Library>Application Support>Steam>SteamApps>steam name>garrysmod>garrysmod>addons. (I am using Mac OSX Lion.) I then started up the game and my addon was not there. Is it possible this addon is outdated, or am I doing something wrong?
Note: This is my first time using an addon, so I’m not very good at this stuff
