The IOGEAR GBU521 is the newest model on this list, and probably the best choice of Bluetooth adapter for your Hackintosh right now. It works well and it's extremely small, but it doesn't necessarily sacrifice range for compactness-- the GBU521 can usually manage up to a 20-foot broadcasting range. However, some people have problems getting their GBU521 to even maintain a 5-foot range, so your mileage may vary. Also, thanks to its newness, the GBU521 is widely available on the internet for relatively low prices.

The GBU521 works in OS X Mountain Lion 10.8 without the need for any extra drivers, and can wake Mac OS X from sleep mode by default with Apple's wireless keyboard, Magic Mouse, and Magic Trackpad. The trackpad occasionally encounters problems reconnecting after waking from sleep, but these seem to be the exception rather than the rule. Unfortunately, the GBU521 is so new that its compatibility only extends to Mountain Lion. The GBU521 isn't supported by default in other versions of Mac OS X-- it requires kext editing to work in Mac OS X Lion 10.7 and Snow Leopard 10.6.
