While doing some troubleshooting recently, I noticed that the `.pkg` installer for macOS of the PurpleAir Utility app is not signed. It’s really not a great idea to have folks bypass the security precautions on their systems to use this app, asking them to blindly trust that the app hasn’t been tampered with is not a good idea. What I found was - the installer isn’t signed at all - the app itself does appear to be signed by a Developer ID, but - the app hasn’t been taken through the macOS App Notarization process ([Notarizing macOS software before distribution | Apple Developer Documentation](https://developer.apple.com/documentation/security/notarizing_macos_software_before_distribution)) as a macOS app developer, I know that jumping through these hoops is a bit of a PITA, but once it’s done once, it’s a lot easier subsequent times and can even be automated. Thanks so much for all the great work y’all do! ---

Thank for bringing this to our attention and linking the necessary steps! We’ll take a look at getting the Utility properly notarized. ---

It’s not super fun, but if you hit a wall, don’t hesitate to avail yourself of a tech support request (there should be a couple included in your Apple Developer subscription). I’ve definitely had to do so for exactly this area of stuff. Their security tools could be more developer friendly 😭
