Try to manually inject the various values of the Capri Framebuffer until you find out the correct one. It's usually 3 or 4 on laptops with HD4000 graphics. With Enoch, you can inject these values via boot parameter IntelCapriFB=xx, where xx is in the range 0 to 11.


If you use Clover, you can adjust this in the Config.plist through the Clover Configurator.

no more Voodoo?


I updated BIOS to A06, still the same "IOGraphics flags 0x43". However no "Previous shutdown code: 5" and the system does not go to black screen, it just hangs. After a while it says "busy timeout[0], (240s), kextd wait(0): 'AppleACPICPU'. Then again "busy" and black screen...


I checked BIOS, it says Video BIOS Version 2132v08, could you please tell me whats yours?


Thanks a lot!
