freeza Posted September 29, 2010 Share Posted September 29, 2010 I've tried virtually everything I can think of to get QE/CI back enabled on my HD4550. I have PC EFI 10.6 SL 10.6.4 and it worked fine (cept with green apple) but with the graphics update, QE/CI has become disabled. Any ideas?

grozhyn Posted November 1, 2010 Share Posted November 1, 2010 finally add support CI/QE in HD4550 (SnowLeopard 10.6.4) after playing around with different versions of ATIRadeonX2000 and ATISupport kexts. ATI4500Controller & ATIRadeonX2000 from 10.6.2 ATISupport - from 10.6.4. EVOenabler for HD4890, with modified device properties for HD4550 (ioreg helps). Last thing i can't manage - right resolution. i have resolution change - up to 2600 and more. but my monitor is 1080p (1920x1080), in my list i have 1600x1200 (working) next one is 1920x1440 (not working, monitor says "out of range") annoying... was trying to flag it with "Graphics Mode" - no changes. any suggestions? P.S i have green apple logo too )) P.P.S about changing EVOenabler.kext look here: http://www.insanelymac.com/forum/index.php?showtopic=213838 Link to comment https://www.insanelymac.com/forum/topic/233223-hd4550-no-qeci-after-graphics-update/#findComment-1574382 Share on other sites More sharing options...
