I have try the ANSI setting but no use.
At the same time I have try to connect another brand name keyboard and can work properly.
So I am wonder why my new keyboard doesn't work on Mac. Is it hardware problem or this keyboard design is not compatible with Mac?
Thank you for your reply.
My Poseidon Z keyboard KB-PIZ is so great on PC. But when i plug in my MAC Book Pro the most character key doesn't work. Is it really cannot use on MAC OS?
