How do i I duplicate a photo on imac
After losing an edit on a recent photo when reverting to original, I searched for ways to duplicate an edited photo to protect it. I see that making a duplicate on an IOS device is simple, but not so on my iMac. Is there a way to duplicate an edited (or not) photo on my iMac?
iMac 21.5" 4K, macOS 10.14
