I upgraded to LR6 and have since bought two new iMacs. From what I understand, I need to deactivate one copy on the oldest machine to activate on the nearest. Deactivate option is not available and I read here not un-install until I deactivate. Starting to sound like a cluster. Can anyone please tell me the right way before I....
I believe you simply sign out of Lightroom on your computer then reinstall it on the new one.
You are permitted two activations. To deactivate use the menu:
Help >> Sign-Out
