: Runs on Windows (requires iTunes or Apple Mobile Device Support) and is also reported to have versions or alternatives for macOS. If your phone started panicking after a screen
Until then, third-party remain the only bridge between cryptic kernel code and real-world repair. As Apple locks down components (serialization), understanding panic logs becomes even more critical—because a "missing sensor" panic might now require a genuine Apple part paired via System Configuration.
