I've waited a while for cross over for mac just to run adobe audition 1.5. i was really skeptical at first as audition wasn't in the list of apps tried and tested. i gave it a worl, it installed quite quickly, and opened with no problem at all, but didn't have a splash screen. when it loaded, i opened the demo multitrack song in seconds, and to my amazement it played without a single click, stutter or pop!. then i opened one of my shows (i work on radio) it was a four hour recording in MP3, it opened in around 3 minutes and played without a glitch. I then tried out some of the effects and they all seem to work ok.
The only issue i have found on first try is that there is no audio in support, just output, so for now i will give it a silver, but that maybe premature until i have given it a full trial, i'll keep you posted.
I'm running audition 1.5 with Crossover for Mac beta Version 6.0b1 (6.0.0b1) on a Macbook intel core duo with 1 gig of RAM.
Hope this helps, i'll update as soon as i can.
