oh yeah, macs, it'll be
sudo dmesg
or something like that, and google for the mac equivalent of lsusb, haven't had to deal with one in ages
theoretically, osx comes with all the drivers you'll ever need, as the harware is dictated by apple, so it's quite posisble the Ga330 doesn't work under the usual mass storage device driver, though it's not that hard to add new drivers to osx, just never remove any, else it's a trip to the apple store to deal with idiots that don't know what a kext is
but whatever, the first step is seeing if it's even plugged in, using something like lsusb/etc, could just be the cable, some don't have the data pins, meant to be just for charging, and some dont have power pins, just for data transfer
...could always just use linux
