In macOS 15.4 (24E5238a) and Xcode 16.2, the NSStatus images appear to be missing.
To reproduce, add an NSImageView to a Nib or StoryBoard and set the default image to any of the NSStatus images: NSStatusAvailable, NSStatusPartiallyAvailable, etc. Instead of the expected Green, Yellow dots, no image is displayed. The same occurs when setting images programatically.
Is the plan to remove these images, or is this just temporary?
Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. Please file a bug report, include a small Xcode project and some directions that can be used to reproduce the problem, and post the FB number here once you do. If you post the bug number here I'll check the status next time I do a sweep of forums posts where I've suggested bug reports.
