I'm having an issue with Lightroom CC. Whenever I attempt to use the adjustment brush, the entire program simply disappears from the screen. I reopen it, and it states that the program quit unexpectedly (obviously). I'm running a 2.9 GHz iMac with OS EL Capitan 10.11.4.
Hi Loyal Apple Geek,
Make sure the program is updated to CC2015.5: Keeping Lightroom Up-to-Date
Also, would suggest you to reset Lighroom Preferences and then, check: Resetting (or 'Trashing') the Lightroom Preferences file | Lightroom Forums
If that does not help, share the crash report.
Thank you for the reminder. I usually assume that all of my apps are up to date as I receive update notifications, but Creative Cloud Desktop wasn't updated, and therefore didn't tell me that both Photoshop and Lightroom needed to be updated. After updating, the issue seems to have been resolved.
