We have developed a secure desktop app using QT, we are developing and delivering this app for more than 2 years. While deploying app we perform codesigning and notarization of app and we use Ventura on build system. So the issue we observed is that if we install this app on any macOS version below Sonoma it works as expected and in Apparency we can see code signature is verified and also app in notarized. But if we install the same app on Sonoma and check in Apparency, it shows signature can't be verified.
macOS Sonoma signature verification failed
I’m a big fan of Apparency, but the final arbiter of correct signing is macOS itself. So, I recommend that you start by running through the process described in Testing a Notarised Product. What do you see?
If that reports problems, I have a bunch of info on how to investigate them in Resolving Trusted Execution Problems. Notably, macOS 14 has the shiny new syspolicy_check
tool, which is a great help in cases like this.
