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?

Hmm i don't know if it will work, but you could try usboverdrive:

Well, i tried the demo, and all it looks at is my mouse. Hmm, i guess more searching is in play.

Not exactly what you're looking for, but you might prefer it:

Nice idea with the Hot Tunes, but those 4 buttons don't seem to be seen in the program nor OS X for that matter.

Thats what I meant when I said it wasn;t what you were asking for. Thought you may have preferred to use hot tunes instead of those keys.

I posted about remapping keys a while back. Never have worked out how its done. I have a Japanese keyboard on my powerbook with a 'spare' key to the right of my space bar. I would love to make it a second command key like newer laptops have.

If you did the Japanese swap, then the PB should recognize the extra key. You should be able to remap it using the built-in OS X software. If that didn't work, then it's just daffy!

(Oh, does the key work when using the Japanese language pack? Just curious)

Not tried it in Japanese mode actually. I don't think I even installed it now I think about it.
How does one remap keys through 'normal os x software'?
I had a look at the pref pane, but there doesn't seem much there apart from swapping modifier keys.
