Your support has change my personal to company name on app store of my ios App, but macOS still use the personal name.

I did do this on clean mac, it is done on github CI, so it is clean mac for sure. https://github.com/rustdesk/rustdesk/blob/1d6037003a24664ac92f2cb390fb94f30468b3a2/.github/workflows/flutter-build.yml#L591 Do you mean the display name is related to notarization rather than signing?

Our app is distributed directly. But I installed a lot of directly distributed mac app, they do display company name.

I also tried to AssociatedBundleIdentifiers in launchagent plist file, it does not work either by following https://developer.apple.com/documentation/servicemanagement/updating-helper-executables-from-earlier-versions-of-macos We tested on macos 15.
