Even though I copied a "gold build" from "TonyMacx86" (the "hackintosh authority"), the machine freezes randomly every hour, sometimes a week. But it will freeze and I'll have to do a hard reset.
Also, many of Apples services won't work with a hackintosh. iMessage and FaceTime, for example. To fix it, you'll need to call Apple and convince them to whitelist your fake generated system ID, risking getting your apple ID banned.
Something also happened during the installation so I have to have a Mavericks USB drive attached at all times to boot the damn thing.
Oh, and don't forget you have to reconfigure the whole thing when you apply an update.
Had I known these things I'd just have saved up a little more and bought the real thing.
