MacBook Pro QWERTY replacement It is a well known story about the origin of the QWERTY keyboard. For those who don't know what I am talking about: QWERTY is built on purpose to be not easy to type.

I figured that no one stops me from rearranging my keyboard to one of the more efficient layouts.

Before I do that, any advice or warning?
In 10.7 Apple provides keyboard layouts for Colemak and 4 versions of Dvorak for your typing pleasure.  You can activate them in system preferences/language &amp; text/input sources.

Best to go to system preferences/users and groups/login options and make sure the box is checked for "Show Input Menu on Login Page" if you activate additional layouts.
