I've just updated to LR Classic on both my Macbook Pro and i Mac. It is functioning perfectly on my Macbook Pro however on my i Mac I am unable to add music to my slideshows. When I select the + sign to add music the screen that appears has i Tunes faded out so I am not able to select it. I updated the iMac to High Sierra before downloading LR.
Any assistance would be appreciated.
What exactly is it that is grayed out - the iTunes library file? I see lots of files grayed out on mine, but it's because they are not valid selections (not mp3 music files). Navigate to the folder where the music files are stored, open it and select the specific music files you want.
