A couple of weeks ago, I wrote about how to connect a PS3 controller with a Mac computer for gaming. The setup was super easy and I experienced great responsiveness with several games. There is one quirk that I discovered that is worth noting. It seems that with the games that I am playing (through Steam) the controller must be turned on and connected before launching the game. Any time that I have turned it on afterwards, it does not work. It is simple to fix. Just close the game and relaunch. It does not even require restarting the gamepad. That can remain on. A minor annoyance, but I wanted to share with anyone who is starting to use the PS3 controller in this way.
