When Apple announced Pasteboard Privacy in May, the general assumption was that it'll arrive in the next major macOS release.
But AFAICS - unless you turn it on explicitly via defaults - it seems absent in the macOS 26 RC.
There's also no mention in the macOS 26 release notes - and the last AppKit release notes Apple published were for macOS 14.
What happened to it? Is it still coming?
