The Matias Wired Keyboard for Mac is for people who miss Apple’s wired USB keyboard. Many people still like the reliability of a traditional USB 2.0 connection with a two port USB 2.0 hub and numeric keypad. This keyboard by Matias has all the special Mac functionality you expect on the function keys. The keyboard has one special function that improves upon the original Apple keyboard … there is a volume control dial on the top edge of the keyboard that gives you more precision in controlling volume than using the keys; however, if you are a traditionalist, you can still control volume with keys on the Matias keyboard, just like the Apple one.
The Matias Wired Keyboard is compatible with Mac OS X all the way back to version 10.6.8 (Snow Leopard)
