Ever since upgrading to LR 5.6 it appears to crash my mac pro after editing a few photos...I have tried all the suggested fixes of creating a new catalog and re-importing files, reinstalling LR, etc...still have the same issue. Baffled as to what to do. Has anyone had this issue and found a fix or know what might be causing the problem? If I can't solve this quickly Im going to need to move to another photo editor...dont have time to be Adobe's QA lab....
What would help would be if you can tell us if it's always the same kind of images or edits resulting in the crasher.
