Mac OS Catalina 10.15.6 There is no "hidden album" in "Photos" Where are the "hidden pictures" ???

I think, the hidden album is there, when I set the language to Hebrew: But the album must not be empty. As a test, hide one photo.

All Menu items seem to be there - but sorry, I cannot read them.

I wonder, if the other menus on your Mac are complete. Is the "Photos" item showing in the upper right corner of the library section? Some users are having the problem, that the library is not showing the "Photos" item, but starting with "Memories".

Check the View menu. There should be a "Show Hidden Photo Album" (if currently not shown) or "Hide Hidden Photo Album" (if currently shown) command there.

You shouldn't hijack this topic but should start your own topic after reading this user tip: Writing an Effective Apple Support Communities Question - Apple Community  

Are you really running macOS 10.15, as shown below your original post?

The menu should be here:

The album will only be shown, if your library contains hidden photos.

Is the primery language of your Mac set to English or a different language?
