Current limitations on macOS

This section lists limitations that are specific to running the Aspect Model Editor on macOS.

No notarization or code signing

The Electron application is currently not notarized or signed with an Apple Developer certificate. As a result, macOS Gatekeeper blocks the app from starting and marks it as quarantined after downloading.

To run the application, use one of the following workarounds:

Remove the quarantine attribute via Terminal:

xattr -r -d com.apple.quarantine /path/to/Aspect-Model-Editor.app

Allow the app manually via System Settings → Privacy & Security: after the first blocked launch attempt, scroll down to the security section and click Open Anyway.

For installation steps on macOS, see Install the Aspect Model Editor on Mac. If you encounter a JavaScript error on startup instead, see macOS: JavaScript error occurred in the main process.
