Hi Kirk,
Attached is the latest Log File as requested.
At this point it seems like this issue cannot be fixed with the current PM version. I have tried numerous, numerous cache sizes, tried loading the images from a different desktop hard drive (SSD), tried using a different monitor, and even downloaded a new copy of the current version and installed it. I changed zoom levels, changed color settings, and used different images from different cameras.
In all cases, rendering RAW files was either slow or unable to be accomplished at all. If I set preferences to render RAW files instead of using "JPG files for speed", thumbnails are generated ok in a contact sheet, but after trying to view 2 or 3 previews, everything comes to a halt on a single image and I can't even close the preview window.
In all cases, once things start to slow down or stop, I generally have have to Force Quit PM to get out of the program. You will probably see this in the log file.
At this point it looks like I will have to wait for the next update for all functionality to be available on El Capitan. I did not update my laptop to El Capitan yet, and all the images I have been trying to use on my desktop work fine on my MacBook Air, including zooming on RAW files, without an issue. It's quite slow, but it still works on Yosemite.
Thanks for your help with this. Please let me know if you have any other suggestions after viewing the log file.
