For coresme2 and other blessed owners of GA-Z68MX-UD2H-B3 with UEFI BIOS U1c
My Step to step to ML Bliss:
My Kit:
GA-Z68MX-UD2H-B3 Rev 1.0 UEFI U1c
i7 2600s (65W with only HD2000, not HD3000)
2x4GB DDR3 Vengeance Blue 1600 running at 1333
Asus Radeon 6670 1024Mb Fanless Graphic Card
Belkin Bluetooth dongle attached on USB hub of Dell 27" LCD
Apple wireless keyboard, trackpad and mouse
Sandisk Extreme SSD 240GB (connected to SATA3-port0)
LG BluRay Internat (connected to SATA3-port1)
prerequisite:
Ati6000controller.kext and atiframebuffer.kext by nataly1967
AppleHDA.kext (ALC889_AppleHDA_10.8_GM_V3+HDEF) by Sergey_Galan
HDAEnabler889.kext
Unibeast 1.5
Multibeast 4.6.1
Kextbeast
chimera 1.11.0
1a. Unibeast ML, downloaded from AppStore, rename/delete Ati6000controller.kext inside Unibeast USB key.
1b. Copy Install_ESD.dmg to NAS for safe keeping
2. Boots Unibeast (no boot flags required with this graphic card), goto Disk Uitlity to format OSX partition for fresh install, resume install and reboot.
Pause and review at 1st boot to Desktop to OSX SSD with unibeast:
Working: Network, Bluetooth Keyboard, Trackpad, Mouse, Eject button
Not working: Graphic only detected having 3MB and running at VGA mode, audio, no bootloader yet on SSD and System Profile MacPro3,1 to be set
3. Multibeast. The current version is 4.6.1 and is not suitable for ML yet. MacMan mention he will push out 5.0.0 soon. So for now I adopted a minimal approach after making error in selecting too many settings. i.e. same selection as Lion is not suitable here for ML.
3.a DON'T check:
Easybeast
UserDSDT
System Utility
Audio
Graphic
Network
3b. ONLY check:
TRIM enable (if SSD supports)
Chimera 1.10.0
System Profile MacPro 3,1 (If you are using Intel HD3000 you need to choose MacMini)
SSDT=i7
Boot Flag: 64 bit GE=No
BootLoader theme is up to you.
4. install latest chimera 1.11.0 over 1.10.0 (why not)
5. graphic (If HD3000/4000 or other graphic card then skip to 6)
5a. rename to backup ati6000controller.kext
5b. rename to backup atiframebuffer.kext
5c. place customised ati6000controller.kext and atiframebuffer.kext on Desktop and install with kextbeast
6. audio (multibeast 4.6.1 didn't work for me)
6a. rename to back AppleHDA.kext
6.b place customised AppleHDA.kext and HDAEnabler889.kext on Desktop and install with kextbeast
7. Repair permission with Disk Utility
8. Reboot
Review at final stage:
Audio works (stereo output, HDMI audio not tested, front headphone socket auto detect not working but can manually choose by alt + click on volume icon on menubar)
Graphics works at full resolution of 2560x1440, QE/CL acceleration confirmed with ripple on dashboard.
Booting without unibeast usb key
Dual booting to Windows works
System profile as Mac Pro early 2008
AppStore, iTuneStore and iCloud signed in
Time Machine backup detected
NAS visible in finder
9. Restore Time Machine backup
9a. Don't choose to restore "other system files" otherwise the kexts and /Extra might get rewritten by Time Machine Restore from Lion.
9b. Install X11 for GIMP
9c. Install Java for LibreOffice
Geekbench 32bit score 10440. up from 9940 with Lion
Enjoy ML
