I guess you should take a look at what installing a hackintosh system entails. It starts with flashing your BIOS and it doesn't get any better afterwards.
You're either running a massively unsupported configuration (even for hackintosh standards) or just plain trolling. I'm posting this from a hackintosh I triboot with Windows and Debian. The difficulty involved reading a HCL when I built the system 3 years ago. The installation involved burning a disc and booting from it.
Nope. You burn the disk and install OSX as normal. Depending on the hardware you might need to download a few kext (Kernal Extensions AKA "drivers") Comparable to installing Linux or Windows.
When I was dabbling with Hackintoshes a few years ago, updating the OS was not supported (regardless of your hardware) and there were a couple of other limitations. Have most major issues like that been sorted out?
Which I did/do for my Macbook Pro anyway. So when I got into the Hackintosh scene, it's second nature. I typically recommend formatting when upgrading anyway. Just doesn't feel right to just upgrade. Maybe it's just left over nightmares from when I was on Windows. Only way to upgrade was to format.
