[README] Common (some unsolved) Problems in 10.12 Sierra

[RehabMan]

Gave it a shot and patched the port numbers and removed/changed the port the same way you did for the Azul framebuffer. The outcome was interesting. Definitely no lag on boot, so that's great. But backlight control (using AppleBacklightInjector) stops working when I use the patches, and the display doesn't wake after sleeping.

I've attached the problem reporting files. Thank you.

You are using ig-platform-id 0x16160002. 0x16160002 uses a PWMMax of 0x65c, not 0xad9. As mentioned in the backlight guide, it means you have to either set LMAX to 0x65c (in SSDT-Config.aml). Or you can patch the framebuffer to change the PWMMax in 0x16160002 from 0x065c to 0xad9.

For example, you could use this patch for AppleIntelBDWGraphicsFramebuffer to change the PWMMax used:
Find: <6C 05 00 00 6C 05 00 00>
Replace <d9 0a 00 00 d9 0a 00 00>

Updating to 10.12.5 seems to have given me back control of backlight settings on my HP 4330s Probook (the thing that had broken down on 10.12.4, which I hadn't fixed manually).

Can anybody else confirm that?

IntelBacklight.kext is still broken here.

Result: No more lag after login and wake from sleep.

OMG, Legend. Previously i couldn't use my laptop (Asus tp500ln) for about 30 - 60 seconds or longer after booting but these new patches (replacing the old) has worked perfectly. Honestly not tested HDMI since implementing this but the effect its had on the lag after boot is like day and night.

Side note: Is there a new patch for 10.12.5 > for boot graphics? The loading bar on my laptop loads a bit then stops then loads more, its not slow or anything just curious. Also i think the screen goes black twice where as before i think it was only once. No biggy just asking. Can post problem reporting files for check up.

Backlight control already working on 10.12.4 if you follow the ProBook guide.
You probably just now updated to the latest github content...

No new patch. Old patch still applies.

It's gone out a Mac-pixel-clock v2 For the 10.12.5?

Which one did you use?
Did you look for the pattern in the binary?

Are you sure you don't have the HD530 problem as per post #1 "10.12.5 Notes"?
Did you check with an external monitor?
