![]() The needed code signing is what’s listed on the designated => line of output: One other thing to watch out for is multiple lines being returned by the code signature check, as I ran into this when checking an application produced by McAfee.Ĭodesign -dr - "/Library/Application Support/McAfee/MSS/Applications/Menulet.app" Code signature fundamentals don’t change that often, but it is something to be aware of when creating the profiles. However, if Jamf ever needed to fundamentally change the code signature it was using for Jamf.app, Example A’s code signature would continue to match while Example B’s would not. Identifier "" and anchor apple generic and certificate 1 /* exists */ and certificate leaf /* exists */ and certificate leaf = "483DWKW443"Įxample A should be considered the least secure as it is very generic in how it reads the code signature, while Example B is the most secure because the full code signature is specified. There’s two ways you can add this information to the profile: If you run the following command, you should get the code signature for the app:Ĭodesign -dr - "/Library/Application Support/JAMF/Jamf.app" Library/Application Support/JAMF/Jamf.app As an example, if you’re using Jamf Pro 10.x to manage your Macs, the following application should be installed on your Mac: That said, there’s two ways that you can do this for third-party applications. The item being whitelisted must be code-signedĪs part of the profile, there is an entry for code signature so that the OS can verify that the whitelist entry matches up against the app requesting the action. How do you find out what the code signature of a particular app is? Run the following command against the application or other item that you want to whitelist: While the current documentation doesn’t provide a lot of detail, based on my research, here is how the whitelist appears to work:ġ. These profiles can only be deployed to macOS Mojave and must be deployed by an user-approved MDM solution. TCC stands for transparency consent and control and was discussed as part of the How iOS Security Really Works session at WWDC 2016: (see the Privacy Preferences Policy Control Payload section.)Īpple refers to these as Privacy Preferences Policy Control Payload profiles, with a -profile-policy payload type. Unfortunately, as of this date, Apple has provided only the following as documentation: What this means is that you may be able to whitelist your most common interactions and prevent them from displaying dialogs. MDM administrators can manage these requests using the Privacy Preferences Policy Control payload, as documented in the Configuration Profile Reference.
