judy22 Posted June 29, 2015 Share Posted June 29, 2015 I finally installed Maverics on my PC.My problem is that the graphics are really poor and when I go to About this Mac -> more info -> Graphics Display 64 MB of Shared System Memory And when I play a video it gives me this error: OpenGL acceleration is not supported on your Mac Your Mac lacks Quartz Extreme acceleration, which is required for video output. It will still work, but much slower and with possibly unexpected results. I tried to patch my DSDT using graphics_HD4K_high patch but nothing changed. my laptop is toshiba satelite c850-b884Processor Intel® Core i3-3120M CPU @ 2.50GHz, 2500 Mhz, 2 Core(s), 4 Logical Processor(s)motherbored intel PLCSF8 HM76BIOS insyde corpgraphics Intel HD4000 ,1366 x768bootloader chameleon Link to comment Share on other sites More sharing options...

mendietinha Posted June 29, 2015 Share Posted June 29, 2015 the patch you use is not for your config. and perhaps it will be helpful to post what happens when you use, for example, the IntelCapriFB=3 and 4. with GraphicsEnabler=Yes. Link to comment Share on other sites More sharing options...

Allan Posted July 4, 2015 Share Posted July 4, 2015 Check if AppleIntelFramebufferCapri, AppleIntelHD4000Graphics and AGPM are loaded. You can see this using this command in Terminal: kextstat Link to comment Share on other sites More sharing options...
