This driver adds support to Mac OS X for the official Microsoft Xbox 360 wired controller. Along with all the buttons, both analog sticks, the analog triggers and the D-pad, it implements Force.

A common way for attackers to get malware onto a Mac is to disguise it as something else, to trick technically naive users into installing it. Fake installers for are particularly favored, and Malwarebytes has found a variant that’s nastier than usual. Flash player download mac os x 10.5.8.

There is no 'official' Microsoft 'Mac Supported' driver at all! They are ALL unofficial, and unsupported.;) If you want a 'native' functioning controller, I hear the PlayStation Dualshock 3 (Bluetooth) works, but I have not tested it.

The 'unofficial' tattieboogle driver is open-source (which means anyone can see the code), the updated (for Mac OS X 10.9) github version of that driver is also open-source, just published by a different author.
