If tccutil is failing or throwing an invalid service/platform error on your Mac, it's because the internal system database schema is out of sync or locked. I ran into this exact loop with the ChatGPT desktop app. To bypass it entirely, I built an interactive script tool that injects the required hardware permissions (Microphone, Camera, Accessibility, etc.) directly into the SQLite database fields using explicit macOS column targets. It features a built-in Finder file selector so you don't even have to look up the application's bundle identifier manually. For complete peace of mind, the guide includes an optional, one-line safety backup instruction so you can mirror your original privacy database to your Desktop and restore it instantly if needed. You can grab the script and follow the steps on my GitHub repo here: TCC-Permission-Manager
