Anyone else have this problem?
Try searching the forum for "el capitan"...
After I restored my lightroom libraries from before El Capitan I did follow the steps from Lightroom and El Capitan | Mac OS 10.11 you suggested. Upon exiting Lightroom CC and then relaunching CC Lightroom crashed as it had before.
Thanks for the tips Chetna. I will continue to follow the El Capitan and Adobe lightroom problem for resolution, hopefully soon.
