labtopia Posted August 11, 2013 Share Posted August 11, 2013 i have a toughbook i've been getting up and running on 10.8.4. i have everything working but the onboard LCD, it uses intel 3000. it goes blank after the apple logo. only the HDMI at that point shows a display. if i use HDMI its all fine but the LCD is not recognized and cannot be detected. i've seen posts about changing a value with hex fiend in AppleIntelSNBGGraphicsFB.kext but that produced an unbootable system. i can find no dsdt for this model and dont know what else to try now. any help with this would be apprecieated. dave Link to comment Share on other sites More sharing options...
