When I open Lightroom CC it will not let me add photos.

[#1]

I'm working on a Mac with the most recent type of Lightroom CC and I have never used Lightroom CC before on this specific computer. I just recently downloaded the app with my subscription and when I open the application and go to the plus icon in the top left icon it doesn't give me the option to add new photos. I can keep clicking the icon but nothing happens, the icon doesn't even illuminate. I've searched through numerous threads and forums for an answer but nothing is helping. I have even tried unistalling and reinstalling the app twice and still no luck. I would assume based off the fact that Adobe is a well respected company and I have used their products numerous times that there should be a reasonable solution to this issue. If someone could try to point that solution out to me as fast as possible that would be great. Thank you in advance.

Do you see your photos that were previously imported? Did you sign into your Creative Cloud account on the new computer with the Creative Cloud desktop application?

Yes I have done everything correct in terms of the logins and Creative Cloud desktop app. Since I have never used this app there are no previouly imported photos but I am still having trouble pressing the add photo button.

What is your computer's operating system?
