I have been lurking in the shadows here for a while, reading and thinking... Now I have finished my first hackintosh project based on the QUO, and wonder how to make OS X 10.6.8 run on it - not the usual noob question, please read on).
Everything does run fine, technically with my new Quo motherboard, 16 GB Ram and Intel.
I had to resort to 10.8.2 which is all nice and dandy, but the reason for me to hack the Intosh was precisely my wish to break out of the Apple jail with regards to the limits of being able to freely up- and downgrade. 10.6.8 is the OS that covers my needs best and all later editions don't. Some family members have a different opinion, and use whatever they like and the same is true for my co-workers. I personally prefer 10.6.8.
Initially SL was all good and ran, except for the use of my Cinema HD display that did not respond to OSX, while working fine with Fedora and giving no hints that anything tangible could be the root cause. I used another small TV monitor using HDMI to display OS X SL (that display was a royal pita). I flashed the BIOS 801 to 828 to troubleshoot the version of OZ being the culprit - but no game. All of the worked and all of them did not help me start SL.
I figured, the system info was the faulty part, as not compatible with my wished for setup, and decided to write the system info into nvram.
I followed the nvram writing routine (sTaN comment #477, currently on of course giving it the appropriate SystemSerial and BaseboardSerial. I assumed, this would release the capability within OS X to use the Thunderbolt port.
So the system showed up as a Macmini6,2.
Alas, it did not and the OS X SL boot disc (original out of the box, family license) did not boot any more, neither did the install (carbon copy from a stripped down version I was running on another system). Then, I figured this was due to the Macmini6,2 systems not being compatible with SL.
So I booted with 10.8.2 and redacted the nvram so it would be a system that according to my understanding would let OS X know that it is compatible with 10.6.8:
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:BiosVersion=IM121.88Z.0047.B1D.1110171110
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:ProductName=iMac12,2
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:SystemSerial=(... as per advice)
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:ProductFamily=iMac
sudo nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:ProductId=Mac-(... as per advice)
I left the base board serial as it was.
In "About This Mac" it now shows as a 27" iMac mid 2011 with 3,4 GHz Intel Core i7 and OS X 10.8.2 (12C60) nicely, and it is blazingly fast.
I did the Darwindump and can share if this would be required, but I am totally puzzled why OS X SL does not work on this nice machine. Booting with both disk and a bootable stick still fails showing only the grey/white Apple screen.
Configuration: Z77MX-QUO-AOS, Intel® Core i7-3770 CPU @ 3.40GHz, 16 BG RAM, Samsung Evo SSD and 828 OZ-BIOS
Would any of you mages have any helpful pointers?
