I see that Mountain Lion has come preinstalled with 4 versions of the Dvorak keyboard layout. I do not think these versions are "Programmer's Dvorak." I found a version of this layout here: http://www.kaufmann.no/roland/dvorak/

After installing it I had no luck finding it in my System Preferences. Does anyone know if this layout is available under Mountain Lion?

It does seem to work on 10.8, but you have to log out and back in after running the installer.


You should run sudo rm -f /System/Library/Caches/com.apple.IntlDataCache.le* in order to invalidate layout caches, and then you will see Programmer's layout in the list.
