already tried NvidiaGraphicsFixup & Lilu which lead to the above screenshot. If nv_disable=1 enabled, it'll have no QE/CI. I guess NVS4200m is really not supported but works perfectly on El Capitan.

Just need the BIOS set with Optimus so HD 3000 can be use instead but the BIOS kept resetting after each restart.

AppleRTC hotpatch doesn't seem to be working, similar to the Dell Optimus.

Going to try RTC8Allow and see if that have any affect.

Hi Jake I tried with El Capitan but I had same problem than Sierra Optimus doesn't work.

With dsdt you passed to me brightness and sleep mode doesn't work. Thanks for helping
