chpe Posted February 19, 2012 Share Posted February 19, 2012 Hello! My HD4570 was working fine on 10.6.6 (except few OpenGL color glitches). After 10.6.8 update several applications are causing the screen to freeze (mouse still movable though), for example Chess, iTunes Visualizer, all the 3D games I've got. Graphics card + QE&CI working using mucha's method: http://www.insanelym...8;#entry1655182 + ATY_Init.kext I guess this user has the same problem: http://www.insanelym...howtopic=272953 , yet he's using Lion 10.7.2 Do you have any ideas? What could I try? Thanks in advance! Link to comment Share on other sites More sharing options...
chpe Posted February 20, 2012 Author Share Posted February 20, 2012 Reverting to 10.6.6 ATI drivers did the trick Link to comment Share on other sites More sharing options...
