So I was at my local Best Buy yesterday, and picked up a Poseidon Z RGB with blue switches. I got home, unboxed it, plugged it into my Mac, and everything worked great. There was some glitches with key rollover on while connected to the Mac, so I just left it off. Then I connected it to my PC, and downloaded Thermaltake's software. It prompted to do a firmware update to version 22, which I did, and everything seemed to be working fine. Today, I plugged it back into my Mac, and... Nothing. It doesn't illuminate, and no keypresses are registered. I went to "Change Keyboard Type" in System Preferences, and the wizard did not recognize any keypresses. I tried with several other Macs, rebooting, and still - nothing. Deleted the plist file for keyboard settings too. It works great while connected to a PC, but not at all while connected to a Mac. I re-flashed the firmware again, and it still does not work on Mac - it was working great before the firmware update (I believe it had version 11 originally though I'm not completely sure).
Any suggestions? I really like the keyboard and don't want to return it, but I can't have a PC-only compatible keyboard, especially if it was working out of the box, then the firmware update took away that functionality. Thanks!
