Shared Albums not working with macOS Tahoe screensaver

Steve Sabol wrote:

We've had a shared album for years that we use as the screensaver on our Apple TVs and Macs in our household.

However, after I updated my MacBook to Tahoe, the screensaver seems suddenly unable to select Shared Albums. It sees all the Shared Albums in the Settings picker that I have, but it does not see any of the photos in any of those Shared Albums.

I wiped my Photos library and let iCloud build a new one.

I forced Photos to "Download Originals to this Mac".

In Photos, I went into that specific Shared Album and clicked through each image to ensure that they were downloaded.

Is this bug specific to me? How do I fix this?

Seems you have done your due diligence...

short of re-install the macOS 26

To be proactive you can file a bug report / submit your Apple Feedback here: Product Feedback - Apple

you can wait and see what is improved in the 26.1 point update when it rolls out and compare your results.
