What type of keyboards and mice does the Mac mini G4 support?
The Mac mini G4 supports essentially all USB-based keyboards and mice (including those with two buttons), ADB-based or PS/2-based keyboards and mice with adapters, and Bluetooth wireless keyboards and mice (provided that Bluetooth is installed or a USB Bluetooth adapter is available). If you use a third-party keyboard designed for Windows, the Mac mini will treat the “Windows” key as a “Command” key and the “Alt” key as an “Option” key. For additional information on keyboard compatibility, please refer to “Mac mini: What Keyboard and Mouse to Use” and for additional information on third-party keyboards, please refer to “Third Party Keyboards May Not Have Command, Option Keys” each from the Apple Support Site.
