OS X 10.5.5 with Kalyway
Due to the lack of use my iMac gets these days I’ve decided to put it up for sale on eBay.
However I still want a Mac around in order to develop future iPhone apps, so I decided to try and install Mac OS on my PC.
I started out trying to use the iAkatos disk however as with previous attempts using this disk, I couldn’t even make it to the installer due to a lack of IDE controller support for my motherboard among other things. This forced me to move on to the Kalyway disk which surprisingly worked first time!
I set about installing Mac OS (10.5.2) onto an external 250gb drive, this worked pretty well and I was able to boot into Mac OS within half an hour of putting the disk in. However I didn’t customize the install and so I didn’t have multiple monitor support or any sort of decent graphics. I choose to reinstall, selecting the correct driver but later found out i could probably have just dumped the right kext into the system.
Following this i ran the Kalyway 10.5.3 Combo update and successfully upgraded with no problems, there are plenty of guides around but the basic process was to run a task that looped, looking to delete a kext whilst the installer ran.
The next step was to install the 10.5.4 update that I grabbed from the Apple site. No problems with this one i believe - the usual reboot then -v -f -x switches. The same process was carried out in order to install 10.5.5, slow and tedious i know.
I stopped at 10.5.5 as I couldn’t find any guides on installing 10.5.6 and didn’t fancy putting all my hard work to waste - I think if i installed 10.5.6 i would run into problems with EFI.
The final step was to get the graphics up and running at full power. After some Googling and playing, I choose to give NVKush a try. This worked great and was much easier than trying to hack around with NVInject. Quartz Extreme works fine and so all the animation works great 
I’m loving using Mac OS on my quad core machine and find myself booting into Mac OS every time i boot up! If only Apple would sell Mac OS for other platforms or at least introduce a Live DVD to get people hooked!
