On start of Photos on my iMac (running macOS Catalina - 10.15.7) I get a message saying: "Not supported library... This library is from a newer version of Photos. Upgrade appl to be able to open library."
Previous use of the library was on my new MacBook Air running macOS Big Sur (11.3.1 - Apple M1).
Is this what causes the problem?

Hi
Yes. The library format is specific to the version of photos. And while photos can upgrade the library from an older version to work with a newer version, it is not possible to go in the other direction.
There is a way to downgrade, but you have to use iCloud. Essentially you sync the library with ICloud using your Big Sur machine, and then create a new empty library on your Catalina machine, and sync that also with iCloud.
However, if your imac is capable of the upgrade to Big Sur, then that would be a better solution.

Thank you, Tony!
That was my guess. Unfortunately my Catalina machine is too old for Big Sur. So I will have to follow your advice.
Thanks again!
New version of Photos (sw: Bilder)?
