I posted this in the OSX Apple forum a few days ago and they directed me here. I'm running Audition 5.0.2 under OSX 10.6.8
Audition can open m4a files from within by using the Open command, but when I use Get Info (from the Finder) to set all m4a files to open with Audition, Audition is greyed. Every other audio program on my mac is recognised as being able to open m4a files, but not Audition.
How do I tell OSX that Audition is able to open m4a files (I do it all the time), so that I can set all m4a files to open in Audition?
