Sims 3 Outdoor Living Stuff (OLS) Installer Not Opening Up! (MAC) [SOLVED]

It seems like the installer itself won't open. The dashboard itself moves, but the icon doesn't come up. I've already tried mounting it using the Disk Utility but it still won't open.

Other expansion worked. This one's installer won't even open.
Have yet to try Late Night.

Thanks for all of your help guys.

//EDIT

Sorry, this has been SOLVED. I didn't check the manual for the Mac, and apparently, I had to install Late Night before I could install the others. Thanks anyways!
