As most posters around here, I've been having severe problems with Premiere Pro 6.02 on OS 10.7.4 FW800 drive, eSATA external drive for project and clips, Macbook Pro 8,3 (early 2011, 16GB RAM, AMD Radeon HD 6750M 1024MB). The project is 1080p50 AVCHD material and psd stills. I'm using Mercury and I have set the System to never use Intel graphics.
The major hurdle was apparently random kernel panics, especially when I tried to scrub using the left/right arrow keys.
That problem was solved when I followed the advice of a poster in this forum, who created a fresh admin account. No more kernel panics!
The 'serious error' crashes remain and are easily recreated:
• I double click a clip (AVCHD or still) in the Timeline to load it into the Source monitor.
• I close the Source monitor by clicking in the 'x' close box in the upper r/h corner.
Luckily, Premiere manages to save the file before shutting down and the file is good to go. The original project file causes a kernel panic if I try to open it, though.
However, I can unload the clip in the Source monitor by using Close in the drop-down.
Also, I can close the Source monitor after it's empty by clicking on the 'x' – no crash.
So, it's the act of clicking on the Source monitor 'x' icon when it's loaded with a clip that triggers the crash, every time.
I suspected that the Microsoft IntelliMouse driver might be the culprit and uninstalled it. Didn't change anything.
I take the liberty of attaching the crash report below, in the hope that someone with better log reading chops than I can spot some crucial lead.
