Administrators Hervé Posted December 21, 2016 Administrators Share Posted December 21, 2016 Systems specs please? You may need to binary mod/patch your FrameBuffer to get all your output ports supported. You can refer to our existing literature meantime.

Administrators Hervé Posted December 21, 2016 Administrators Share Posted December 21, 2016 Install Display Menu app (available for free on AppStore) to check if you can switch from mirrored displays to separate/independent displays. Your IOReg shows: FB@0: ​no attached display FB@1: connector-type = 00 04 00 00 (DP) port = 0x5 boot display = true FB@2​: ​connector-type = 00 04 00 00 (DP) port = 0x6 FB@3: ​no attached display Which framebuffer layout-id are you using? Once you've identified it, you can try to identify the framebuffer table in the Skylake framebuffer kext and investigate a potential binary patch.

Administrators Hervé Posted December 22, 2016 Administrators Share Posted December 22, 2016 Erm... you would have had to specify it somewhere in your bootloader configuration to get macOs running. If you did not, it's highly unlikely that you have proper graphics support. Link to comment Share on other sites More sharing options...
