The Sims 3 Installer App Problem [SOLVED]

Hi, first of all I wanna thank you guys for the amazing work and effort you put into this, I was having trouble trying to install the pets expansion pack nothing worked until I used the Ultimate Fix guide you guys provided and it did wonders, thank you so much!

First of all I am using a macbook. Ok so after I decided to install other expansion packs, starting with the lowest size of them so I can try if they work after I replaced the cracks, I came into this little annoying problem.
The expansion pack I downloaded first was Katy Perry's Sweet Treats from the torrent file on G4TW's account on tpb.. After I finished downloaded and unzipped the rar folder I tried opening the Installer App included in the folder It kept bouncing on the dock and did absolutely nothing, and when I clicked it it disappeared from the dock.. I can't open the installer!

Please   !!


//EDIT

I found a fix!   

I used Stuffit Expander to unzip the torrent file I downloaded and when I opened the Installer it worked and it installed!
However I don't know how to open the expansion pack? I opened the expansion pack from the application folder but it started the pets instead, How can I open it?


Edit: I started the game but there's no expansion pack items for Katy Perry? Did I do something wrong?




//EDIT


I fixed it again!   

I simply uninstalled it and installed it again and everything went perfectly perfect! 

Thank you guys again!
