Garry's Mod has problems with OS X Lion, HELP!

I’ve installed Garry’s Mod on my Macbook and it works but I’ve looked everywhere and I can’t find the addons folder!
I’ve looked on some sites and they say that it has some problems so when will Garry fix this, it’s so annoying!

Someone post

Go to your admin folder, library, application support, steam, steam apps, your user name, garrysmod, then addons i think it will be there

Went there, don’t work.

You can create your addons folder manually in garrysmod/garrysmod/.

Ok. To get to your steamapps folder it is in the applications support (which is hidden in lion)Add me if you want direct help
