SynoCxtMenuSIMBL Agent
SynoCxtMenuSIMBL Agent is a helper component for SIMBL, a system-level plugin loader for macOS that allows third-party developers to inject code into running applications through bundles called SIMBLs. This particular agent, from Culater, manages context menu extensions for Synology file-sharing integration. The component runs as a launch agent in the background and is not separately installed or updated outside of the parent SIMBL framework.
AI Recommendation
1 suggestionSynoCxtMenuSIMBL Agent is a helper component that is updated only when the parent SIMBL framework or its host integration is updated. SIMBL itself is a legacy macOS system-extension framework that has not been actively maintained since the early 2010s, and Apple has significantly restricted the injection mechanisms SIMBL relied on in modern macOS releases (10.11 and later). As a result, this component is unlikely to function correctly on current macOS versions, let alone run natively on Apple Silicon. If you are seeing this component on your system and wish to use Synology file sharing on macOS, contact Culater or Synology directly to ask whether they offer a modern, native Apple Silicon replacement for the Synology context-menu integration. If no such alternative is available and SIMBL itself is no longer active, the component will cease to function when Apple removes Rosetta 2 in macOS 28 (September 2028). For ongoing Synology access, consider using the Synology Web Station or official Synology macOS apps if available for your use case.
