Nice, I personally spent hours trying to figure it out because there weren't any comprehensive guides for Mac installation. I made a guide, but sadly it isn't nearly to par with this. It just shows you how to manually install (obviously a program like yours is better lol) and you have to do the right click searching crap everytime you want to update something -_-

Alright, so I had a pain in the butt trying to install this thing because there aren't exactly the most accurate instructions for mac users. If you unzip where the current posts tell you to without removing the files from the folders and such it gets all messed up, so this is my solution. I hope it makes life easier for someone, because it took me about 2 and a half hours to get this mod installed (though admittedly it was my first time using a sims mod, so that had a lot of effect on the matter).

Before you get started you'll need to download these files,
The awesome mod itself: http://www.moreawesomethanyou.com/ts3/base/awesome.zip
and the framework for the mod: http://www.moreawesomethanyou.com/ts3/base/framework.zip
If you want to make life easy on yourself so you can copy me step by step then save them into a folder called "downloads"

Due to the size of this image I'll be linking it, it can be found at this url: http://img200.imageshack.us/img200/752/installingawesome.jpg

Anyways there you have it, enjoy.
(one last thing, I know the awesome files get copied into two locations and they probably don't need to be... but it worked so I'm not messing with it lol).
