I have a problem with graphics accerlation in OS X 10.10. In 10.9, my HD 4600 works flawlessly by Inject Intel and Inject EDID in Clover, but in 10.10 it does not work anymore. I have tried adding ig-platform-id for my HD 4600 but nothing happens, still no QE/CI. I wonder if someone could help me sort out this problem. Thanks a lot. Here's my DSDT if you need to do anything with it Thanks .
Intel Core i7 4700HQ 2.4GHz
16 GB DDR3L 1600MHz G.Skill RipJaws.
1 TB 5400rpm (slowww like hell)
Intel HD 4600 + nVidia GeForce GT 750M Optimus (Optimus is known not to work, so it has been disabled in DSDT, I just need to get my HD 4600 working with full QE/CI Accerlation).
Clover r2696 UEFI.
