jp.co.canon.MasterInstaller is a privileged helper tool and launchDaemon component that is part of Canon's printer and scanner driver installation and management system for macOS. It does not run as a standalone application but instead operates in the background to support Canon printer/scanner drivers, handling installation, updates, and communication with Canon devices. The component is installed and managed as part of Canon's Master Setup installer and related Canon device software. A native Apple Silicon build has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionThis is a helper component within Canon's printer driver ecosystem, not a standalone app. It is updated automatically when you install or update Canon printer drivers through Canon's Master Setup installer. If you have a Canon printer or scanner connected to your Mac, download and run the latest version of Canon Master Setup (Mac) from Canon's support pages for your region—this will install or update both the visible driver software and the underlying MasterInstaller component. The fact that a native Apple Silicon build has already been sighted in our community means Canon is actively shipping native versions; when you run the Master Setup installer, it will automatically detect your Mac's architecture and install the appropriate native build. If you are in the US, visit support.usa.canon.com and search for "Master Setup"; if you are elsewhere, check canon.com with your regional domain (e.g. asia.canon, in.canon, etc.) and search their support section for Master Setup. There is nothing to "update" or opt into separately—just run the latest Master Setup installer for your Mac, and the component will be refreshed as part of that process.
