I need to deactivate and uninstall on old mac in order to load it onto my new system...can anyone help?
You would first open Photoshop CC on the old Mac and select Help menu > Sign out... Then in your Applications > Adobe Photoshop CC folder use the "Uninstall Photoshop" utility, never drag the folder to the Trash.
But you should know you are allowed two activations. If you are not going to give away the Mac, why not keep around for emergency use?
Thanks... Got it. And for some reason I thought I still had to on install it. I will keep it installed and just sign in and sign out. Thanks for your help!
