ONProxySupport15 is an embedded framework component of ON1 Photo RAW, a professional photo editing and RAW processing application for macOS. The framework provides proxy support functionality — enabling efficient previewing and editing of high-resolution images by working with lower-resolution proxy files — which is essential for smooth performance when processing large RAW files. A native Apple Silicon build has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionONProxySupport15 is not a standalone application but a framework bundled inside ON1 Photo RAW. There is no separate download or update channel for this component — it is updated automatically when you update the parent ON1 Photo RAW application itself. If you are running an older Intel-only version of ON1 Photo RAW, simply update the main application to the latest version available from ON1's website or your existing installation's built-in auto-updater (typically Help → Check for Updates or a notification prompt). The latest build of ON1 Photo RAW ships with a native Universal Binary that includes the native Apple Silicon version of this framework, so updating the host application is all you need to do. After updating, the framework will automatically run natively on your Mac.
