Can't run GTA SA on Macbook Pro!

I have downloaded GTA San Andreas from uTorrents and there wasn't no errors during installation but now after it's installed i cannot run it. The icon for GTA SA has appeared but when i click on it... nothing. I also had the same problem with CSR Racing Game which i downloaded from Apple Store.

I am using a: Macbook Pro, Processor 2.5 GHz Intel Core i5, Memory 4 GB 1600 MHz DDR3, Graphics Intel HD Graphics 4000 512 MB and Software OS X 10.8.2.

Can anybody help me please?
