Hugh Sierra DP7 - Intel HD4600 with 4790k

Hi,

To perform a successful normal Boot without gIOScreenLockState 3 i need to disable internal iGPU HD4600 in Gigabyte bios. Never had trouble with it before, ever worked in 10.11 and 10.12 since. Any ideas ? Maybe now need of a ID or fake ID string changes in Clover?!

Thanks in Advance.

IGPU set as primary?

IGPU set as primary?

No GeForce 980 is primary and display connected. But worked so far without any problems.

IGPU must be primary in dual GPU setup.

OK thanks for the hint. Never had a problem so far in 10.11 or 10.12 with PEG First. Maybe NVIDIA Webdriver in final 10.13 High Sierra will solve the boot problem.
