Hello,
I have a dell e7470 and follow this posts.
Well i modify kext and ssdt with WhiteDragon's posted, but no good news.
So touchscreen don't work, but is recognized by UUPID, and SD Card is recognized bu DPCIManager, but i can't managed with it.
Also i swaped ApplePS2Controller with VooDooPS2Controller and at least on boot start with recognize my keyboard.
Overall it's good enough, with brightness, screen resolution, all 3 usb working and sound as well, but if someone could managed with touchscreen and sdcard, will be perfect for me.
