CS55 ScreenSaver

This is a screen saver extension, not a standalone application — it runs as part of macOS's built-in Screen Saver system. There is no separate download or update channel for individual screen savers; they are either bundled with macOS itself, installed as part of a vendor's main application, or placed directly into the Screen Savers folder by an installer. To update CS55 ScreenSaver or verify it runs natively on Apple Silicon, check whether the vendor (Co) offers a native installer or application that includes this screen saver. If the screen saver was installed as part of another application from Co, update that parent application to its latest native version — screen savers bundled within modern apps typically ship natively. If you installed this screen saver directly from a vendor download that is no longer maintained, note that custom screen savers must be re-installed on macOS 28 (September 2028) to continue working, as Intel-only extensions will stop functioning when Apple removes Rosetta 2. For best compatibility, contact the vendor to confirm they offer a native Apple Silicon build of their screen saver module, or look for alternative screen savers built into macOS or offered by vendors with active Apple Silicon support.
