I am running lightroom cc 2015.4 and the quit lightroom and the import function just stopped working. So I cant get out of lightroom to restart.
I am on a mac running OS X El Captain 10.11.6
Force Quit LR. If that doesn't work press and hold down the power button for a few seconds until the system shuts down, turns off.
But if this is something that happens a lot then you have a problem with your Mac.
