InstantOn
InstantOn is a HAL (Hardware Abstraction Layer) audio driver component for macOS CoreAudio, developed by Rogueamoeba. It enables low-latency audio routing and virtual audio device management, allowing other audio applications to capture, route and manipulate audio signals system-wide. HAL drivers are essential system-level components that work behind the scenes to support audio applications like Rogueamoeba's own Airfoil, SoundSource and other third-party audio tools that need direct CoreAudio access. The driver is not a standalone application but rather an embedded system extension updated as part of Rogueamoeba's audio software products.
AI Recommendation
1 suggestionInstantOn is a system-level audio driver component, not a standalone app, so it cannot be updated separately. The driver is bundled with and updated through Rogueamoeba's audio applications — most commonly Airfoil, SoundSource, or Rogueamoeba's other CoreAudio-dependent tools. To ensure InstantOn has a native Apple Silicon build, update the Rogueamoeba audio product that installed it. Visit rogueamoeba.com and check for the latest native build of whichever Rogueamoeba app you use; run the vendor's installer to update both the main application and its bundled HAL driver. If you are uncertain which Rogueamoeba product uses this driver, contact Rogueamoeba's support directly at rogueamoeba.com — they can confirm which of their apps have native Apple Silicon builds and which update channels ship them. Keeping your Rogueamoeba audio tool current will automatically keep the InstantOn driver current and native.
