May be my Problem can be solved here...

 

i use an Intel DH67VR Mainboard with an Ivy Bridge I3 3225 CPU.

Im running Sierra 10.12.5 with Clover 4077 and no DSDT.

 

The only Problem is the HD4000. Only every 3 Boots the HD4000 works.

Other time i get an Error in verbose Mode and no Acceleration.

The HDMI Audio (with Audio Piker Alpha script on the fly Patch) then of course not working to.

 

If the HD4000 works,       i get some "SNBGraphic..." Errors and

if the HD4000 not works, i get some "AppleIntelCapri... " Errors on Start in verbose Mode.

 

Clover is on default settings, SMBIOS is MacMini 6,2 , only the Intel Inject with ID 0x166000A i have set.

 

Is there a workaround with Clover or must i use a DSDT to fix it ?

May be some Users has a Solution for me.

Thanks !

 

EDIT:  now i have made a dsdt, put the Patch from Rehabman into it and it works! Thank you RehabMan for this !!!
