Gatekeeper problem: deploy policies.json on MacOS 15.61
I would like to centrally distribute and manage Thunderbird 140 (ESR). We have decided to configure it via policies.json, as we want to manage Windows endpoints as well as Macs.
In a later stage, the installation script will be distributed via Intune.
I am currently testing the script on my Mac with macOS 15.6.1. The script performs the following steps:
I am able to create policies.json and the distribution folder, but Thunderbird can no longer be started because the app is corrupted.
After some research, it appears that Gatekeeper from MacOS is probably responsible for this. When the policies.json file is saved, the code signature is no longer valid after startup. As a result, Gatekeeper no longer allows Thunderbird to run.
Does anyone have any ideas on what I could do to prevent this problem from occurring?
