[solved] Iris 550 Issues

[yjplayer]

Got it work, it shows 1536MB (which is still not enough).
But now there is some flickering at the top left corner. How can I fix it?

update to 10.12.4beta and the problem has been solved

It is correct.



I guess you missed the pinned thread.

Graphics work correct now.

I can't get the brightness control working. Tried to fix with IntelBacklight.kext and your DSDT brightness fix.
Can you please help me to fix this?

Add 0x19278086 to the IOPCIPrimaryMatch in the Info.plist for IntelBacklight.kext (under "Haswell Broadwell Skylake Handler")
Or use FakeID/IntelGFX=0x19268086 (as in guide config_HD550_P530.plist).

Thanks, it works now!

But my next problem is the sound. I've patched it like provided here: http://www.insanelymac.com/forum/topic/298663-applehda-for-yosemite/, but it doesn't work.
My laptop has 100series mainboard so I renamed HDAS to HDEF.

Can you please help me?
