Hi, I've been using the MBox for a couple of years now and it's been a great setup for me. Here is my dilemma. I'm still running OS 10.3.6 with Protools LE 6.4. I have the installer discs for Protools 6.7 and 6.9 and i really want to upgrade both Protools and my MAC OS. Does anyone know from experience which version of protools works with 10.3.8? That's the OS I'm planning on upgrading to. Thanks in advance.
