no matter what i do i can't get it to work i get it installed and it sit's at the mac loading screen and thats it i cant figure it out.

ok im sure this makes a big difference every thing that came with my Mobo say's 750sli chip set but Cpuz says Northbridge-NVIDIA nForce 650i SLI SPP rev. A2 \ Southbridge-NVIDIA nForce 650i SLI MCP rev. A3
The Msi Website and Mobo box\book even says Chipset NVIDIA® nForce 750i SLI (C72P) Chipset NVIDIA® nForce 430i (MCP51) Chipset so im at a lose on this but i know it has a big to do with why mac wont work least i strongly believe i say that with out trying to sound stupid lol im just tired of trying almost i have spent count hours on this been least 2months or more and still no answer in sight so if you all have any idea's im open im trying very very hard to work this out so please any adivce is greatly welcome
