I'm using the latest Version of Lightroom on Mac (Version 10.13.6) but the button to add photos is completely greyed out (same is true when I try to attempt this from File > Add Photos). I've tried installing older versions of Lightroom and even tried installing it on a separate Macbook Air and in both situations I ran into the exact same issue.
I'm on a Student License (with Duke University) and have scoured other posts about similar issues but can't seem to work out a fix. I also reached out to the Duke IT Team and they told me they can't help so I'm stuck between a bit of a rock and a hard place. Any support would be greatly appreciated.
“Federated (Corporate and Education) Licenses can download and install Lightroom Desktop. However, Services need to be enabled on your license in order to use the product.
Lightroom Desktop relies on storing your catalog as well as your images in the cloud. If your license does not allow for Cloud Services, you will not be able to add photos to your Lightroom catalog and the option will be grayed-out.
If this is the case, you can contact your Adobe License Administrator and ask them if:
Services are available with your license
If your account can be enabled for services
Lightroom Classic is also likely available via your Federated License and does not require Cloud Services to function. It would be another option for you”
