I almost went the Hackintosh route, but decided to play it safe for now. I ended up purchasing a 2010 2 x 3.46Ghz 6 core mac pro. So far, it's been ok. I was hoping the rendering speeds would be faster. While it is over 2x faster than my previous iMac, I was hoping for a little more gain, especially considering the GeekBench scores of each computer (~7800 for the iMac and ~30,000 for the Mac Pro).
My biggest complaint is how hot the machine runs, even when I'm not doing intensive work. I've been holding off on updating the graphics card because of the heat issue. I didn't realize about Apple marking computers obsolete until I talked to my local computer shop to see what I could do to cool things down and found out that mine was marked as obsolete and they weren't allowed to work on it (since they were an authorized Apple dealer).
I will chime in here in support of your experience. My big monster rendering machine was bought as a Hackintosh, thinking this was the best option to getting around Apple's lack of vision.
Unfortunately, while MacOS can be tricked into running these machines, it is not for the faint-hearted. I'm a designer, but not especially gifted when it comes to the technical side of electronics. Every OS upgrade on a Hackintosh is a potential show stopper as every component in your hand assembled investment may or may not be supported by the OS's drivers. You could potentially be spending days flashing video cards and troubleshooting hardware incompatibilities.
Even with the dual E5 Xeon processors, this machine needs to be networked for Maxwell to perform at production levels, but the Hackintosh's ability to communicate reliably with the Macs was severely hampered by the hardware discrepancies between machines. Renderings would run like bats out of hell, but then I'd get wierd error messages about the ability to connect and the entire render sequence would fail (leaving me the next morning with no deliverables)
When I branched into Octane and GPU rendering, I discovered that because of Apple's sealed box designs, virtually all Nvidia's cards are spotilly supported on the Mac side, as Apple has unilaterally decided AMD's incompatible video card architecture would be the only available choice.... All the top of the line Nvidia cards I was looking at would need to be "flashed" to run on the Hackintosh. Between you and me, I'm really uncomfortable with the idea of messing up a $1200 video card (voiding the warranty) just so I can run MacOS.
If you're super comfortable with computer guts, cards, writing scripts and otherwise performing brain surgery on thousands of dollars of computer hardware, yes, the Hackintosh is your solution. I took my expensive box, and had it reassembled into a Windows based machine. I grit my teeth every time I boot it, but at least it's stable and I can buy accessories off the shelf.
