Well, i bought a G15 for my PC when i had it, but i have since went to a Mac again. I like this keyboard, but there are some quirks to work out. I have been able to figure out the keys for the command and option keys under Tiger. Also switched the keys (ALT & Windows Key) so they match what the mac person sees, but there is a small problem i have encountered. The G keys are the same as F keys but that's not my problem. The media keys are not functional. Is there some way that i can get them to work like the Elite keyboard i had? Play, next, back and stop. The volume and mute buttons work, but that's it for media keys. Any ideas out there in the Mac community?
