Mounting and viewing a CD/DVD within iPhoto is no longer available.
I bought a new Apple external DVD player in 2018, but now it is not working.
This is the message I got today. I do not know what to do—
"Mounting and viewing a CD/DVD within iPhoto is no longer available. To access photos on a CD/DVD created with an earlier version of iPhoto, copy the library to your computer and open it."
