CES 2007 -- Sprint Nextel has announced officially supported Mac OS X compatibility with one of its EV-DO Rev A cards. Previously the easiest way to get EV-DO on a Mac was to go with Verizon (Mac OS X offers built-in support for a couple of the Verizon cards). Compatibility is for the AirCard 595 hardware only. Users can simply download a free application (Watcher Lite) from Sierra Wireless to get the device working.
Because the supported card is a PCMCIA type it will not work in the latest generation of Mac laptops. Those computers feature an ExpressCard slot which is an up and coming form factor that's incompatible with the wider PCMCIA connector.
