Help installing on a mac

Hello. I just got a mac, and I've installed all of your sims 3 expansions on my PC, but I'm unsure how to do it on a mac.

Could I get specific instructions?
Or a list of things to do?

There may already be one, but I looked and couldn't find anything.

Hey.

Here are the links you will need in order to install the game.

Link #1: http://www.games4theworld.org/index_files/downloads.htm
Link #2:http://adf.ly/246619/http://www.mediafire.com/?0ey542202mj9002

The first link has the exact instructions on how to install the Sims 3 and its expansions.
The second link is the fix and cracks for the game(s).

Please refer to the forum if you have any other questions. Thanks!

I have tried to make the Disk Image, but the app for installing doesn't open. it's bounce and crash...

Please help!

//EDIT

it's for the expansion Generations

//EDIT

Ok the install as open and work well, but now the crack doesn't work...
