Acer v3-772G Mavericks 10.9.1 Build

[pmdevita]

Hi!
I have followed the instructions in the thread and successfully gotten Mac to install and boot correctly! So thank you all! However I have a bit of a problem.
On Windows, I partitioned off 20GB to start Mac on but I have been unable to get the Unibeast installer or my Mac install (which also runs on a flash drive) to partition it to HFS+, much less actually load Mac on it. Instead, it just hangs at preparing and never moves forward.
Is there some special way to do this? Is the hard drive locked down somehow by Acer? I was able to load Linux Mint on another partition that doesn't seem likely. Any thoughts or any other data I could give to help?

Thanks!

OS X is not well behaved with disks partitioned by other than OS X Disk Utility, but there are things you can check/do.

Hi, I managed to install osx mavericks with the help of marcussmith2626 post # 117, everything went well, one problem would be unable to modify brightness but isn't a problem. I did the update and 10.9.5, as all goes well. My question was, someone tried to install OSX Yosemite?

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 them on USB for transfer to OS X.

It is not necessary to install Linux. Simply run it from USB: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows

In Linux Terminal:

# substitute DEST with the mountpoint of a FAT32 formatted USB stick
sudo cp -R /sys/firmware/acpi/tables DEST

Place all SSDT/DSDT in a single directory (rename them to *.aml as you move them) and use a recent build of iasl to disassemble:
https://bitbucket.org/RehabMan/acpica/downloads

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

Then search the resulting *.dsl so you know where GFX0 is defined. Search for "Device (GFX0)"...

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 the file (SSDT or DSDT) with GFX0 device definition.
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). Obviously different locations for Clover (EFI/Clover/ACPI/patched).

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

Thanks for the reply, yes I have gone through your tutorial, but I do not do big problems because of brightness, works any combination of the fn + besides that, I do not bother me. Instead I wanted to know if it works on Yosemite without many problems. I am newbie ..: D

Procedures for Mavericks are almost identical for Yosemite.

The stickies here are useful: http://www.tonymacx86.com/yosemite-laptop-support/

Hello,
I have a problem in Yosemite. When I want to wake the laptop from sleep the screen stays black.
What could be the problem?

Did you implement backlight control?

Which ig-platform-id are you using?

Yosemite questions should be asked in the appropriate Yosemite forum. This forum is for Mavericks.

Yes I know that this is for Mavericks, but the setup is pretty much the same and a did't want to open a new thread only because of this problem.

My ig-platform-ld is 0x0a26000a

Yes I implemented backlight control (picture attached)
