macOS 26 Tahoe Screen Saver issues

Noticing a few issues with Screen Savers in macOS Tahoe developer beta 1 :

  • The command
open x-apple.systempreferences:com.apple.ScreenSaver-Settings.extension  

no longer works to open the Screen Savers preference pane. The reason? There is no longer a Screen Saver preference pane - it still exists, but it's now a Modal dialog (that can not be resized) that is opened from within the Wallpaper preference pane, by clicking a button.

  • Something funny is happening with legacyScreensaver - I think that
ScreenSaverView.Init(frame:isPreview)

may be passing wrong values, e.g. the isPreview boolean is false in Preview mode?

  • I've submitted Feedback # FB17895600 about some of these, and will report back more as I figure things out.

Please feel free to add to this thread, thanks!

Thanks for testing this stuff immediately and then filing those bugs. Screen savers are such a niche thing that it’s critical to get this issues noted early in the beta cycle.

If you encounter any other issues, please post the bug numbers here so that they’re on my radar (so to speak).
