So recently, I've been trying to get my Lenovo y570 laptop to run Mac OS X Mountain Lion. I installed with Unibeast which worked perfectly and have it running OK except for Audio and Wifi. However, I have an BCM4321MC in the mail to swap out the card in this laptop (already patched the whitelist in the bios). But I was hoping that I would get better support and battery life / speedstepping by using a patched DSDT for my board.
I had never even heard of a DSDT until installing OS X and have no idea where to start. I pulled the DSDT from Windows which is located at the link below as a dsl file (due to file size not permitted by the forum)
Boot your laptop and when you see tonymac icon hit any key to interrupt the booting.
Type -v and hit enter again to restart the booting process. You will see a bunch of kext scrolling up when it stops take a photo and attach it here.
