Hi there. This is a bit off topic for this forum but since I know a lot of you use Apogee products I thought I'd ask. I have an older firewire version of the Apogee duet that I've been using for about 5 years. I like it so much that I made sure I bought a MacBook pro that still had a firewire port. All went well until I upgraded to Mavericks. I downloaded the new Mavericks drivers for the Firewire duet. Logic 9 works fine, however iTunes does not, particularly movie and TV show playback, though music seems fine. Pops and crackles everywhere on video playback unless I unplug the duet and just go through my computer's speakers. Then the pops and crackles disappear. The movie and shows also work fine through Apple TV. The stuff is on an external HD. I've been talking to Apogee support about this and they're as baffled as I am. Anyone have any ideas what this might be?
