eSellerateValidator
eSellerateValidator is an embedded XPC service component bundled within Whisk, Tumult's web design and prototyping application. The validator handles licensing and registration checks through the eSellerate licensing platform. As a sub-component of Whisk rather than a standalone app, it is updated automatically whenever Whisk itself is updated and cannot be installed or updated independently.

1 suggestioneSellerateValidator is not a standalone application — it is an embedded XPC service that lives inside the Whisk app bundle and handles licensing validation. There is nothing to update separately; updating Whisk itself will automatically update this component along with the rest of the application. Check Tumult's website (tumult.com) for the latest version of Whisk and install or update it through whatever distribution channel you originally used (direct download, Mac App Store, or an in-app updater). Whisk's native Apple Silicon support status will determine whether this component runs natively or under Rosetta, so verify that you are running the latest Whisk build available for your Mac to ensure full compatibility as Apple removes Rosetta 2 in macOS 28 (September 2028).
