FireROR Posted February 14, 2014 Share Posted February 14, 2014 I didn't use clover but I switched my dsdt file to the high resolution dsdt file in your post. The USB port on the docking are working. GREAT!!! But the DVI/DP ports are still not working. The VGA became manual, which means I have to leave it on then reboot the machine. Before it was automatically detected. I didn't use clover which means I didn't use the config.plist file you provide, (I think) I did replace AppleIntelSNBGraphicsFB.kext before with OP's version. Is that the reason why the video port not detected? Thanks This is AppleIntelSNBGraphicsFB output. 000000: 0002 0300 0000 0000 ffff ffff ............000000c: 0205 0000 0004 0000 0700 0000 ............0000018: 0304 0000 0004 0000 0900 0000 ............0000024: 0406 0000 0008 0000 0600 0000 ............0000030: 0000 0000 0100 0000 4000 0000 ........@...

tluck Posted February 14, 2014 Share Posted February 14, 2014 @FireROR - well yeah if you swapped the original ket with a patched SNBGraphics buffer that would explain it. go back to the original kext and your DVI on the will work. then you can figure which port you give up if you want to enable VGA. btw, that set of buffer does not look like the right for a laptop - i look more like what folks do for a desktop with monitor. what os version are you on? the original should look like this for MBP8,1 0000000: 0102 0400 1007 0000 1007 0000 ............ 000000c: LVDS_0503 0000 0200 0000 3000 0000 ........0... 0000018: HDMI_0205 0000 0004 0000 0700 0000 ............ 0000024: DVI_0304 0000 0004 0000 0900 0000 ............ 0000030: HDMI_0406 0000 0004 0000 0900 0000 ............ which are 1) LCD 2) DisplayPort on left side 3) Dock DisplayPort 4) Dock DVI and my high-res DSDT has an EDID for 1600x900 - so you may want to remove that bit.
