If you have a Mac that doesn’t feature Bluetooth 2.0 + EDR connectivity and you want it, MacMice has a solution: the $29.99 Danger Dongle, a USB stick that provides Bluetooth networking capability for a Mac or PC.
Bluetooth is a wireless personal area networking technology that enables Macs to communicate with printers, headsets and other devices. Bluetooth 2.0 + EDR (Enhanced Data Rate) provides better throughput for compatible devices, up to three times faster than the previous standard.
Bluetooth 2.0 + EDR has only recently been broadly available — many devices still feature the slower 1.1 implementation. Apple has adopted Bluetooth 2.0 + EDR on newer Mac models, but many older machines either use Bluetooth 1.1 or lack Bluetooth connectivity all together.
The Danger Dongle is a small white “stick-type” Bluetooth adapter that occupies an available USB 2.0 port on the Mac or PC and is plug-and-play compatible with Mac OS X and windows XP.
