I have been thinking of picking one up tomorrow but i am looking for third party software.

The g15 tools has a how to compile and install. However, i don't know how well it works and i really want someone to try it before i go buy one.
But to answer your question no its not just a double click, you have to follow the instructions and compile it.

According to this: http://forums.logitech.com/logitech/board/message?board.id=mackb&message.id=814

The GamePanel software by logitech supports the LCD for mac.
This also supports it: http://orderedbytes.com/controllermate/compatibility/?show=logitech except no LCD. It doesn't really explain very well if all the other keys are supported or just some of them.

This also might be able to run the LCD screen, but not for sure: http://www.entropy.ch/software/macosx/lcdtool/

Anyone with a g15 please give us some answers it would be great!
 
Time to resurrect a dead thread, but Logitech now have G15 drivers. It works great, only thing that doesn't seem to work is the RAM in the performance monitor.

I have a Mac Pro with 10GB RAM, and for some reason, just general usage (Safari, iTunes, Mail + Adium) uses approximately 92% of available RAM.

Here is the link.
