JACKOSX no longer requires Aggregate Device: change Ardour first-time user page
From JACKOSX 0.85 documentation:
"Starting with Jack OS X 0.84, it is no longer necessary to create and use Aggregate Devices on Intel Macs"
I guess this needs changing:
"Making sure you have a duplex audio device (INTEL USERS ONLY)" (http://www.ardour.org/first_time_osx_native)
Sorry if I shouldn't have posted it here but it seemed to be the only place.
