When it comes to 360 controllers, will both the 360 version and the Windows version work on a Mac . . . ?
I'm assuming that the Windows version won't need any drivers and will be more compatible.
All versions of the gamepad (Xbox 360/PC & Wireless/Wired) will work but they all require drivers (the drivers are open source on the Mac and have a few side effects/bugs). The wireless 360 pad does not use Bluetooth instead it has it's own special proprietary frequency which requires a special Microsoft dongle. This means the wireless version of the pad requires you to buy the USB 360 wireless dongle as well as installing the drivers.
Microsoft do not offer Mac drivers so the only option is the open source ones I mentioned above which sometimes have compatibility issues on some peoples Mac machines.
No versions of the XBox 360 gamepad will work on Mac (or Windows) without installing special drivers first.
Hope that clears up any questions on the 360 pad on the Mac.
Cheers,
Edwin
