Although several other Linux distributions support the Power ISA, Yellow Dog Linux was distinguished for its focus on supporting the Apple Macintosh platform before the Mac transition to Intel processors. Before this transition, Terra Soft Solutions held the unique distinction of being the only company licensed by Apple to resell Apple computers with Linux pre-installed (or for that matter, with any operating system other than Mac OS X). Full support for AirPort (Apple's implementation of the IEEE 802.11b-1999 wireless networking standard), and partial support for AirPort Extreme, are also built into Yellow Dog Linux, as are support for Bluetooth and support for accessing the Internet over cellular phones.
