Just received this email from Apple today:

> We’re following up on our previous email announcing that you’ll soon need to transition to the notarytool command-line utility (included with Xcode 13 or later) in order to continue notarizing your macOS software with Apple. Notarizing software with altool was deprecated in Xcode 13, and **the Apple notary service will no longer accept uploads from altool as of November 1, 2023**. Existing notarized software will continue to function properly.

For information on notarizing your apps, read [TechNote TN3147: Migrating to the latest notarization tool][https://developer.apple.com/documentation/technotes/tn3147-migrating-to-the-latest-notarization-tool?changes=\_3\_3](https://developer.apple.com/documentation/technotes/tn3147-migrating-to-the-latest-notarization-tool?changes=_3_3).

FYI - “Notarytool” requires Mac OS 13 (Monterey).
