When I updated to OS X 10.7 Lion on my Hackintosh, I got a weird issue where the hard drive would wipe itself every few days – like, I would turn on the computer, and it would tell me the hard drive was blank and had no operating system on it, and I had to reinstall everything all over again.
(To be clear, this was the first issue of any kind my Hackintosh had ever gotten.)
At that point, my business had gotten successful, so I could afford to buy a 2013 Mac Pro and stop worrying about what went wrong.
So I bought the Mac Pro... and its SSD still wiped itself after a few days. Turns out, the problem was in Lion's exFAT driver. I'd partitioned it into HFS+ for Mac, NTFS for Windows, and a shared exFAT partition, like on my Hackintosh, and Lion just couldn't handle that.
I gave up on having an exFAT partition after that, but kept the Mac Pro because it was so nice (it was also much quieter and smaller, which let me put it in my backpack for hackathons).
