We've developed a data-only driver for owners of Mac laptops running Mac OS X, version 10.2.5 or later. This is the only support solution we know of that has a full installer so you don't have to hack your system to make it work.
Once the driver is installed, your Mac will see this amazing AirCard 555 as a Modem, which you can even use in a Virtual PC environment!
This driver requires Mac OS X version 10.2.5 or later. For now, card activation requires a Windows PC, but this process is often performed in the store when you purchase the hardware, anyway. Once the card has been activated, to use it in your Mac OS X laptop, this driver software is all you will need!
