Administrators Hervé Posted May 30, 2016 Administrators Share Posted May 30, 2016 Well, if layout-id 01660009 is the only one that seems to give your graphics acceleration, I guess that's what you should stick with. Regarding black screen on wake, you could try and use boot option darkwake=0 to see if it makes any difference. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted May 30, 2016 Administrators Share Posted May 30, 2016 I don't believe these log messages are an issue. If you end up with a booted OS X with full QE/CI, then consider things work. Link to comment Share on other sites More sharing options...
cooper1 Posted May 30, 2016 Author Share Posted May 30, 2016 ok understood .also to sleep with this command (darkwake=0 ,1,2 etc) not change anything.

Administrators Hervé Posted May 30, 2016 Administrators Share Posted May 30, 2016 Ha, that's different from the description you gave before. I understood your laptop went to sleep Ok but just woke to dark screen. Assuming you configured hibernation mode to 0, what you'll probably need here is a DSDT patch... None of your EHCx/XHC USB devices or HDEF audio device appear to have the (usually) required _DSM method: Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method { If (LEqual (Arg2, Zero)) { Return (Buffer (One) { 0x03 }) } Return (Package (0x0B) { "AAPL,current-available", 0x0834, "AAPL,current-extra", 0x0898, "AAPL,current-extra-in-sleep", 0x0640, "AAPL,max-port-current-in-sleep", 0x0834, "AAPL,device-internal", 0x02, Buffer (One) { 0x00 } }) } Try either of the attached patched DSDT tables. The 1st one includes the above patch in EHCx, XHC and HDEF devices; the 2nd one has same + _PWR methods removed.

Administrators Hervé Posted June 1, 2016 Administrators Share Posted June 1, 2016 I edited and compiled the above DSDTs with MacIASL, make sure you have a recent version of the app. Link to comment Share on other sites More sharing options...
