Mac PRO Desktop — any issues?

I had a report of a crash on Mac PRO running a standalone built with MaxMSP ver. 2.0.5 (40079).

Any known issues with the Mac PRO’s? Anybody have one who could help beta test in exchange for a free copy of the app?

Oops. Should read built with Max 2.0.8.

An additional bit of info (from the end-user):

>On my MacPro, when I looked at the audio driver, it defaulted to the iSight camera as input source. I changed >that, but it didn’t help. Then I just unplugged the iSight, restarted MacPOD, and it works. Problem solved.

I’m wondering if the dac~ is trying to access sound output on devices that don’t have them.

For the Cycling74 folks, if you want to recreate and have a Mac PRO with an external iSight, you can download the shareware app at It’s called MacPOD.
