I’m working with TCC/PCCC permissions in UEM. Why would I need a Script Library instead of just relying on Policies? Shouldn’t Policies be enough?

Wait, what exactly are TCC and PCCC permissions? I’ve heard the terms but never really understood them.

Thanks for raising this question. Let’s break it down first:

TCC (Transparency, Consent, and Control): This is Apple’s framework that manages app access to sensitive data and services, like Camera, Microphone, Screen Recording, etc.

PCCC (Privacy Preferences Policy Control): This is the MDM/UEM mechanism that lets admins push policies to control those permissions centrally.

Now, Policies are really the baseline, they define the rules and set the intended permissions for apps and services. But in practice, permissions don’t always behave perfectly. That’s where Script Libraries come in. Scripts act like a troubleshooting toolkit: they can reset permissions that get stuck after updates, give standard users the ability to toggle settings like Screen Recording without needing admin rights, and even validate that the TCC.db database reflects the policy correctly. There’s obviously more to the subject, this is just the gist of it.
