Problem with Photoshop CS6 Freezing up on OSX Mavericks
I would use opensnoop to figure out what it's doing when it hangs.

I've used the following command to watch a process and log the results to my desktop while watching the results live.

Once your figure out which file it's hanging on, you might be able to determine what the next step should be.


  ps aux | grep -i Photoshop | head -n 1 | col | cut -f 2 | cut -d' ' -f
  1 | xargs -I {} sudo opensnoop -v -p {} | tee -a ~/Desktop/logfile.txt
