Download help for Mac OS X

I downloaded a few files for Gary’s Mod (weapons, ragdolls etc.) And I do not know how to use them in the game. PLS HELP!

Put them in steam/steamapps/yoursteamname/garrysmod/garrysmod/addons

I can’t find those files on my computer. Would you mind telling me where to find “steamapps?”

its in Your Mac username/Library/Application Support/Steam/Steamapps/yoursteamname/garrysmod/garrysmod/addons

But thats only if the files are in addon format. It works the same exact way as on PC.
