-6085 (is this the error you are encountering ?) Is a very common error mentioned in at least a dozen threads in PT 9 mac os x with PT9. (please search other threads with your problem before posting a new one, this will help Avid).
Anyway, If you look around the DUC youŽll find many users performing several attempts to solve, despite the random behaviour of the error.
Despite the very kind help of many users who suggested to follow the standard Avid troubleshooting procedures and system cleaning, the error, in most cases, is still there.
I always thought it was a problem with PT 9 or/and external hard drive firewire chain. But I discovered something new today: I tried a friendŽs macbook pro with PT 8.0.4 and my avid mbox pro, no ext firewire Hard drive. We got the -6085 as we accidentally touched a random key on the macbook pro. This confirmed somehow another cause of -6085 produced with my Mac pro quad-mbox pro sometimes: opening or closing an application (like Mail for example) during a PT session, caused 6085 err. (PS this was not happening with PT 8 and Mbox 2 pro or 002.)
Now, once the first 6085 error is produced, there is no way back. The session goes on producing it. The way out is quitting Pro Tools and restart, or toggling the session clock. Then it goes on fine again for a while.
(Please Avid read this), I might obviously be wrong, but it is my believe that the problem not only lies in PT9, but also in the mbox pro drivers
and the mbox firewire.
