how to connect the i-glasses to a mac

It's quite easy to user your PC i-glasses with other computers too:
All you need are two adapters: one for the VGA monitor cable and one for the serial-interface. For USB macs you can use a USB to serial adapter. This is also the case for newer PCs which dont come with a serial port anymore.

There is no official driver available for the Mac, but since our java driver is platform independent, you can use it on MacOS X (and Linux) as well. For both platforms you will need the RXTX CommApi implementation to add the necessary serial port support.
