The issue mentioned in this ticket is still present in the latest master.dmg
Tested with macOS 10.15.7

[~aloraine] - release-9.1.4 is the branch I should be using for IGB 9.1.4 right? I was trying to notarize the application by following some steps specified in https://www.excelsoftware.com/movie/macinstaller.mp4

I am not totally sure of the details I will need to input to the clickInstall app. i have attached the screenshot of the details I have filled in. Kindly let me know what else need to be filled before sending the app for notarization. (For example - License agreement, background image, installer image, min MAC OS requirement, min RAM )

Before you try to notarize the installer, can you please make sure that the open ports in IGB will not cause a problem with the notarization process?

I am concerned that if you submit our application for the process, it will detect the open ports and flag our software as malicious or dangerous.

Can you please check into this aspect before proceeding?

https://www.youtube.com/watch?v=1kfwwaC_O80 and https://www.youtube.com/watch?v=f9hQmp1Cp8w talk about the application requirements for notarization.
They haven't spoken anything about the application being rejected because of open ports or any such thing. The only thing is that our application shouldn't contain any malicious content.

Mostly we can go ahead with the notarization.

As per https://developer.apple.com/documentation/xcode/notarizing_macos_software_before_distribution/resolving_common_notarization_issues we can resubmit an app if it gets rejected after fixing the discovered issues.
