IdleScreen documentation
A signed and notarized macOS Tahoe screen saver with a native companion Studio.
IdleScreen turns procedural scenes or a live camera into a Metal-rendered field of animated characters. It is a signed and notarized macOS Tahoe screen saver with a native companion called Studio. The companion controls the look, the embedded extension renders it, and a separately signed camera agent owns the whole camera lifecycle.
