If you have an account on Origin then you might be able to find a copy on there. You will not have any expansion packs left though. Other than that you don't have any other choices than to go out and buy another game.
no, you do not need your Sims 3 disk, but you will need the disk for the expansion pack you want to install.
you put in the disk and press install
Exactly the same as when you installed The Sims 3. Just insert the disk, and follow the steps. :)
no you just put it into your comp and install it regularaly
Use the base game
generations ,pets,seasons,super natrual,the sims 3 ,town life,and all..
to install the game, you would need to buy an external disk drive so you can run it.
Sims 3 will not damage your (or any other) Mac. Sims 3 loves Macs.
You obviously buy the game, then you put the disk in your disk drive and it will come up with a box with the sims 3 logo in it, then click that and it will come up with a sims 3 install wizard and if you go through the steps that are shown and walla! hope this helps
