nexuscan replied to Ondra MisÃ¡k's question in Hackintosh Mountain Lionguys, I have Asus a53sc model laptop with same specs. Intel HD 3000 working well with QA and transparency windows and menu bar. But I cannot load nvidia graphic card. Geforce GT 520 MX can you help me about that. I just wanna use also nvidia. ps: there is no option in bios change video card.
