Thanks and I need your help to patch my DSDT.aml.
Another 2 issues bothered me a lot after installation:
1. AppleALC unable to load due to lack of layout-id in HDEF. ALC1220 failed. Only DP audio from HD 630 & HDMI audio from GTX-980.
2. Unable to boot by newer Clover versions (> r.4268) either hanged at +++++++++++, kernel panic or loss of display from Intel HD 630.
