Apple Intelligence is now available on iPhone, iPad, and Mac!
"My Photo Stream" no longer appears in Photos since updating to 10.14.6, and recent photos taken with my iPhone no longer appear in Photos on my MacBook. iCloud settings in both the Mac and the iPhone have My Photo Stream turned on. I do not use iCloud for my photoslibrary, and that has never presented a problem with My Photo Stream with prior versions of macOS.
How is My Photo Stream turned on in 10.14.6?

The answer through trial and error: The macOS 10.14.6 upgrade requires the Mac user to re-designate the existing photos library as the "System Photo Library." This is accomplished through Photos>Preferences>General, then (if not already selected by default) select Photos Library Main in the Pictures folder, and finally click on the button "Use as System Photo Library." My Photo Stream will reappear in the Photos Library.

I learned from a more recent similar issue with My Photo Stream after I upgraded to macOS 10.15 Catalina that if the button "Use as System Photo Library" is greyed out, the _____.photoslibrary displayed just above that button already is your designated System Photo Library. https://discussions.apple.com/thread/250714500
Sorry, does this mean you have to change libraries if your library location is an external drive? "Use as System Photo Library" is greyed out for me, and my Photos library is on an external drive.
