I just read every post in this thread and I can't tell you how good (bad?) it feels to hear others having the same problem I am. My issue, however, is that I came into this A/V position four months ago and, at about month 2, all this happened.
In short (very short), The MacBook Pro crashes within 30 minutes every single time I use it. It's so frequent that I've gotten to the point where I think "I've been working too long. I better shut down." As with all of you, the main issue seems to be Final Cut Pro X (10.0.6) although I have been in Safari and Google Chrome -- with FCPX closed -- and it's crashed.
By the way, by "crash" I mean beach ball --> unresponsive while beach balling --> force shut down --> wait a few minutes --> repeat.
All of the clips and footage I'm using (short of backing audio tracks or stills) is housed on external Seagate Barracuda 3TB drives that I access through Thermaltake toasters (the BlacX Duet via USB 2.0 and the BlacX 5G via 3.0 respectively). I have also worked with footage (.mts files converted to .mp4 files using iSkySoft Video Converter) transferred from a Panasonic HDC-TM700 and still experienced the crashes.
I have taken it to a local MacAuthority in order to have a diagnostic run on it and all they could tell me was "you need a new logic board." Not equipped with the time or money to go that route -- plus, I don't believe that's problem -- I thanked them and have been working around the crashes since.
Here's the deal. I'm not a Mac guy but I LOVE Final Cut Pro. I don't want to be forced to go Sony Vegas or Avid. Has anyone found a solution other than "switch graphics cards?" And please remember, I inherited this machine and the guy before me purchased FCPX through the Apple Store -- i.e. not a hard copy -- and I do not have his login information to do the uninstall/re-install dance (or update, for that matter).
Thank you for your time and thank you so much for giving me some actual adequate information!
