Sisilkounet Posted June 7, 2013 Share Posted June 7, 2013 Hi, I'm looking for help. I've succesfully install Mountail lion on my laptop but I just can't have full accelaration for my graphic card. I tried to make it work using EFI string injection with no success. I want to bielive it's possible by patching DSDT, but when i try to add the patch, I'm not able then to compile it... There is a lot of thing to learn for me, but I'm doing my best to understand how all that work... This forum really help me ! But now, I'm stuck... Here is my specs : Acer V3-571G Intel core i5 3230M Intel HD 4000 w/ Nvidia GEFORCE 640M (optimus technology) I join my DSDT, if someone can help me or learn me something. Thank you a lot for your help, Oliv dsdt.zip Link to comment Share on other sites More sharing options...

Sisilkounet Posted June 8, 2013 Author Share Posted June 8, 2013 Hi, thank you so much for your help. I've tried your patched DSDT, and made some progress ! However, there are some strange things : when i start my laptop with screen plugged on the hdmi connector, everything is working fine... on the internal display : full QE/CI, but nothing on the hdmi screen. And if I start with nothing plugged on HDMI, it just don't start... stuck on apple logo ! Is there a way to fix this ? Anyway, thanks again for your help !
