If you havenвЂ™t already, install AppleвЂ™s developer suite Xcode through the App Store ( link). LetвЂ™s get to it, shall we? Xcode 10 or later This tutorial is largely based on AppleвЂ™s own Customizing the Notarization Workflow article, but adapted to Glyphs.app plug-in development. Then you can staple the ticket to your plug-in and ship it to your users. After a while (couple of minutes for my plug-in, results may vary), you receive a confirmation of the notarization from Apple by e-mail. In the natorization process, the software is uploaded to Apple servers using a command line tool that comes with Xcode 10 or later called altool. If you plan to distribute a Glyphs.app plug-in yourself, for instance because your plug-in is commercial or other reasons prevent you from including it in the Plugin Manager (which can only distribute plug-ins hosted in public Github repositories), you must have your plug-in notarized by Apple. Plug-ins that are installed via Glyphs.appвЂ™s built-in Plugin Manager on the other hand are exempt (for the time being), probably because Glyphs.app itself is notarized and therefore counts as a trustworthy gateway. Sadly, all this applies to plug-ins for Glyphs.app as long as they are downloaded via a browser or come in by e-mail. For offline use, developers can staple the ticket (a confirmation of successful notarization) to their software so that Gatekeeper can trust it even without internet access. Apple keeps a database of safe software that macOSвЂ™s Gatekeeper mechanism queries when a software is downloaded from the internet and used for the first time. Developers upload their macOS software to Apple servers where they are scanned for malicious code. With the dawn of macOS Catalina in October 2019 came a new security feature to our computers: Apple requires all software downloaded from the internet (including by e-mail) to be what they call notarized.
