With the latest updates in Lightroom CC 2015.2.1 on a Mac (El Capitan 10.11.1 with latest updates), I can no longer bulk export raw photos (Fujifilm RAF files) to JPG. It will successfully export approximately 20 files and then hang up, requiring a force quit of the application. I have used these same settings to bulk export similar files many times previously without problem. Help! On a Mac Pro with 64GB memory, Lightroom cache cleared and increased from 10GB to 20GB and still fails.
