Although plenty of discussion
exists on successfully installing
OS X on Gigabyte GA-G31-Series motherboards, I preferred the
: It supports a faster bus
and memory speed
than the Mac Mini (1066MHz)
. The downside is limited
capability when used with
the Q9300 CPU. Unfortunately, my online research uncovered
almost no discussion on a Hackintosh based on this
motherboard, and I resigned myself to waiting until more information
became available. Fortunately, a user at the tonymacx86 website
this motherboard literally days before I planned to purchase my
hardware, but provided few specifics on the exact
method (perhaps because (s)he
assumed there were no "newbies" in the
Based on some further research, and a little trial-by-error while
installing OS X, here are the exact BIOS settings I eventually used:
Motherboard: BIOS Settings
Menu Option to:
||Y (ie: Yes)
|This option must be set first, otherwise it may
reset any previously-changed settings.
||CPU Clock Ratio =
Fine CPU Clock Ratio = +0.5
|The Intel Q9300
CPU uses a 7.5X clock ratio. Board autodetected 7X.
||First Boot Device
Second Boot Device = Hard Disk
Third Boot device = Disabled
HDD SMART Capability = Disabled
is handled by OS X, as reported by Apple's Disk Utility.
||Init Display First
||PEG = PCI Express
PCI IDE = Disabled
On-Chip SATA Mode = Enhanced
USB Keyboard Function = Enable
USB Mouse Function = Enable
USB options allow the keyboard to function during OS X install.
||HPET Mode = 64-bit
ACPI Suspend Type = S1(POS)
Power On By Ring = Disabled
enables Sleep in OS X. NOTE: If ACPI = S3(STR) the hackintosh will not
wake from sleep.
Initial OS X Install: tonymacx86 Method (iBoot 2.5.3
software was actually a lot easier than I
thought, thanks to those smart people at tonymacx86
who've written an
install process and the software packages "iBoot 2.5.3"
and "Multibeast", all of which can be downloaded from their site. For
Multibeast I selected the Easybeast
option: I didn't find a custom DSDT file designed for the Gigabyte
GA-G41M-Combo motherboard and did not want to risk using a
DSDT file written for another Gigabyte board.
NOTE: As of March 7, 2011, a DSDT
file has been created for this motherboard (available
here). I've not tried this; If you've had success using this file
with your Hackintosh I would appreciate any feedback.
Despite reading the
well-documented tonymacx86 process and available forums I still
encountered a few
problems, nearly all
of my own making. These tips made the install process proceed a little
- iBoot.iso CD: The
iBoot.iso file needed to be burned as an ISO Image, not as a Data Disk. (One method: Using an existing OSX
computer, open Disk Utility, select Image
-- > Burn, then select the iBoot.iso image and burn. After the disk
is burned, verify ISO Image format by mounting the disk and using Get
Info. When verified, unmount the iBoot.iso image from Disk Utility by
dragging it out of the sidebar.)
- Enabling USB Keyboard:
the OSX Retail Disk was loading, pressing <F5> as instructed had
effect. Problem was traced to the keyboard not being recognized.
Solution was to Enable USB Keyboard Function in the BIOS.
- Installing OS X:
needed to be pressed while the disk was loading (ie: the
activity light is lit on the optical
drive) allowed installation. Pressing it
after the activity light stopped blinking did nothing.
- Expansion Cards:
tonymacx86's instructions, only the video card was installed.
(In my build I
installed a known 100% Mac compatible Firewire card. During OS X
installation a Kernel Panic occurred, even when booting up in Safe
Mode (ie: invoking "-x" option prior to booting). Booting up in Verbose
Mode (ie: "-v" option) revealed the Firewire card as the cause.
the card allowed installation to proceed.)
- Tools: "OSX86
Tools" were installed while running
Multibeast to make it easier to install any needed kexts after
installing OS X.
- Custom Installs:
Custom installs were performed before
updating to OS X 10.6.5, to prevent losing any functionality. (I
performed mine after upgrading to OS X 10.6.5, causing the Sleep option
to freeze the computer: Sleep was restored only by erasing the hard
tonymacx86 process from scratch.)
- Custom Install
After the Custom Install was finished, OS X reported that some of the
installed files were older than those already installed on the computer
and recommend re-installing the latest OS X update. I ignored this
warning; otherwise, see: Custom Installs,
During initial startup of OS X it requested a User Name: Having
purchased all the components at my local Microcenter, I chose the name
Post Install: OSX86 Tools + kexts
The only method for installing OS X on a PC that's guaranteed to
provide 100% functionality is to install OSX on an Apple computer: On
non-Apple approved PC hardware (ie:
additional software always needs to be installed to enable various
and even then some functions may still not be available or function
In my case almost everything appeared to work, including Sleep,
Restart, and Shutdown. Restoring the missing functions required the
installation of only three kernel extensions (aka: "kexts")
. To install the
kexts, I used the program
"Kext Helper b7", part of the "OSX86 Tools" package installed earlier
when running Multibeast. (Alternately,
I could have installed the "OSX86 Tools" package at this point by
simply re-running Multibeast.)
Here's a summary of the missing or sub-standard features after
installing OS X, how they were restored, and remaining problems:
- Audio In/Out:
"VoodooHDA ver. 0.2.1.kext" to enable the backplane audio ports.
- Sound is either fully
on or fully off (although the slider
can be adjusted).
- Case's front audio ports (AC'97 spec) are not working.
- LAN: Installed
"Atheros1cEthernet.kext" to enable it.
- Firewire: Installed
Firewire PCI card. Fully functional.
- Graphics: System
reported OSX recognized only 32MB of the 512MB Video RAM. Installed
"NVEnabler.kext" to correct.
- Display: When using
VGA port, System
Preferences --> Displays lists all available screen resolutions, but
changing the resolution results in a blue
Display Resolution Solutions:
Shut down the computer by pressing and holding the power button for
seconds. Restart, and the selected
resolution will appear. While this works, the computer doesn't like
being shut down this way.
Solution: Use the keyboard to put the computer to
Sleep (Option + Control + Eject).
Wait a second or two, then wake up the
computer using the keyboard: The new resolution should now
Connect the VGA monitor to DVI using a DVI-to-VGA
The installation is complete!
