Builds are unsigned. On Windows, SmartScreen may warn on first run. On macOS, right-click OpenStudio and choose Open, then allow it in System Settings → Privacy & Security if prompted. The Linux AppImage needs chmod +x. Code signing costs money the project currently spends elsewhere. If you want certainty, verify the checksum above.Before upgrading, back up projects, recordings, presets, NAM models, and cabinet IRs. Projects and presets using retired formats require conversion; renaming a file does not convert it, and automatic migration is not included. Keep the older app for unconverted sessions.

The optional AI Tools have their own hardware notes: what the runtime needs
AI Tools
Stem separation and generation need the AI Tools runtime, installed once from the AI Tools button inside OpenStudio. It is never bundled into the base installer.
AI Tools setupHow update checks work
The app reads public release metadata to tell you a newer build exists, and you can check manually from Help → Check for Updates. It only reads metadata to discover new versions. It does not sign, download, or apply patches silently in the background.
