MAC Keyboards Difference between Advance line and Pro line keyboards? The difference is that the Advance line keyboard has all white keys that have had the colors printed on the top surface of the keys as well as the text. The Pro line keyboard has had fully colored keys installed in place of the white keys and has the text printed on the top surface. Knowing this, I think that if you look at the photos on the web site you will see the difference.
