I use a Mac with OSX (Yosemite). Recently, when using LR to edit some photos, I found that the program quits unexpectedly after the crop tool is used. I have to reopen the program each time. Getting to be quite tedious. Any suggestions?
I have the same problem, so I am following your thread. It just started last week??
Try disabling the GPU.
Go to Edit > Preferences > Performance (on a Mac: Lightroom > Preferences > Performance), and uncheck Use graphics processor.
