Dell XPS 12 (9Q33) OS X Mavericks Instillation

[RehabMan]

Yes was a clean boot and the value is at maximum, if i change the brightness the value also change and is written ok the nvram.plist file in the root volume, but every reboot it goes back to max

You should check the value after reboot ('nvram -p' in Terminal). You can also install the debug ACPIBacklight.kext and check system.log to see what is happening. It is likely you don't have EmuVariableUEFI-64.efi installed.

installed latest VoodooPS2 but cannot wake from keyboard\mouse, I can use the Power button or Windows button on the display.. not bad

regarding NVRAM, i attach a screenshot of my EFI partition.. may be i've too much *.efi files :\

the nvram -p after a reboot is not the same of nvram.plist (currently only brightness differ)

Not all computers can wake via PS2. Not a kext issue.

Looks fine.

the nvram -p after a reboot is not the same of nvram.plist (currently only brightness differ)

Check bootlog to see what nvram.plist is loading. Maybe it is loading from another partition (time/date problem).

Also, what version of Clover?

i'm using Clover r2959 (latest avaliable), checking all logs there is no entry of "nvram.plist" during the boot
may be there is a Daemon that should be launched at boot to set nvram?

thanks!

Then you don't have EmuVariableUEFI-64.efi installed.

how it's possible.. it's in the EFI/CLOVER/driveruefi64.. as my last screenshot..

Haswell Brightness Fix:

You will need to extract all DSDT/SSDT from Linux. Your GFX0 device is in one of the SSDTs not DSDT and to get a proper disassembly of your DSDT (and the SSDT that has GFX0) you will need all of them. They are available in /sys/firmware/acpi/tables and /sys/firmware/acpi/tables/dynamic.

Place all SSDT/DSDT in a single directory and use a recent build of iasl to disassemble:
http://www.tonymacx86.com/attachmen...ell-inspiron-17-7000-hackintosh-able-iasl.zip

cd "to directory where you placed all SSDT/DSDT"
iasl -da *.aml

Then search the resulting *.dsl so you know where GFX0 is defined.

Laptop repo: https://github.com/RehabMan/Laptop-DSDT-Patch
Apply: "Rename GFX0 to IGPU" (to both DSDT and the SSDT that has your GFX0 device)
Apply: "Brightness Fix (Haswell)" to SSDT with GFX0
install: https://github.com/RehabMan/OS-X-ACPI-Backlight

Place patched DSDT.aml in /Extra/dsdt.aml. Place patched SSDT in /Extra/ssdt-1.aml (assuming you have already generated SSDT.aml for CPU)

Result: Working brightness slider in SysPrefs->Displays (mapping of keyboard keys is a separate issue), possible LID sleep, and IGPU power management.

I followed these instructions but cannot seem to get the backlight to work. Will SSDT-7.aml only work if I have a SSDT.aml installed? And I assume the EFI/ACPI/patched is where I am putting these files? since I am not using an Extras folder.

Download patchmatic: https://github.com/RehabMan/OS-X-MaciASL-patchmatic. Install it to /usr/bin.

In terminal,

mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

i've got Yosemite installed without any problem with my current Clover configuration, also power management and backlight works without problem, also Audio with VoodooHDA 2.8.5

still need the s-RGB profile to avoid artifact (still present on the login screen after first boot)

now i'm gonna install Windows in another partition and try to unlock all BIOS feature to remove MSR lock and rise the framebuffer size to see if the artifact disappear

hope this week to get the Broadcom NGFF card and check if the DSDT patch works under Mavericks and Yosemite (but i should be)

i'll keep you updated

@donradii

if you want, i can pass my EFI partition.. i've the i7 version, i think you should only regenerate SSDT.aml for PM
