Can you see the line6 audio midi device in the system preferences? did you use the latest installer from their site?
Yup, it's indicated on the "system preferences", however, when I run the Gearbox and Line 6 Monkey, it doesn't detect the hardware. I've installed using the bundled CD....I was able to track the latest software released last November '08, haven't tried it though...I'll try installing it later. Shall keep you guys posted. Thanks.
PS: It works perfectly fine with my PC laptop running on XP...so meaning there must be a glitch on it's compatibility with Mac.
