From your screenshots, your max display should be 1366x768 which means you should be using the lowRes DSDT instead of the default HiRes DSDT, but as long as you graphics looks fine, just leave it I guess. Looks like you have an Intel Wireless, head over here and see if you're wifi is supported, otherwise, replace with an DW1510, DW1550 for Wifi / BT combo. For audio, add the following kexts: Lilu.kext, AppleALC.kext and Whatevergreen.kext If you have added AppleHDAIDT.kext to /L/E or /S/L/E, remove it, repair permissions and rebuild cache Finally, in the Config file, under KextToPatch, disabled all the patches for AppleHDAIDT 1 Link to comment Share on other sites More sharing options...
