Running 'tccutil reset microphone' gives the error message 'tccutil: Failed to reset microphone'. The same command worked in the past. Deleting the TCC.db files didn't help. In the console there is an error from the tccd daemon saying

handle_TCCAccessResetInternal: Invalid Service Name: kTCCServicemicrophone(Service name is invalid on this platform)

Any ideas?

The trick shown by StewMacLean no longer works on my Mac (macOS 15.5) but it’s relatively easy to adapt it to the modern world:

% dyld_info -exports /System/Library/PrivateFrameworks/TCC.framework/Versions/A/TCC | grep kTCCService | cut -c 33-

WARNING This obviously relies on lot of implementation details. It’s fine to use this during development, but do not encode these implementation details into your final product.

Try:

Code Block  % tccutil reset Microphone

Note the capital M.

The fact that tccutil provides no way to get a list of services that can be reset is a source of ongoing annoyance to me (r. 58754400, 15330520). Here’s my personal list of the most common ones:

Code Block  Accessibility
AddressBook
AppleEvents
Calendar
Camera
DeveloperTool
ListenEvent
MediaLibrary
Microphone
Photos
PhotosAdd
PostEvent
Reminders
ScreenCapture

In another thread someone asked me about the service names for System Preferences > Security & Privacy > Privacy > Files and Folders, so here’s an extension to the list I posted above:

SystemPolicyDesktopFolder
SystemPolicyDocumentsFolder
SystemPolicyDownloadsFolder
SystemPolicyNetworkVolumes
SystemPolicyRemovableVolumes

And here’s one more that crops up regularly:

SystemPolicyAllFiles

And there’s one other detail I’d like to record: Some TCC services are system wide and some are per user. It’s easy to tell which is which using the following process:

Set up a fresh Mac (I typically do this by restoring a VM from a fresh snapshot).
Log in as user A.
Enable the TCC service, either explicitly in System Preferences or implicitly by perform an action that presents a confirmation, depending on the service itself.
Log out.
Log in as user B.
Is the service enabled?

Needless to say, that’s a bunch o’ work, so here’s a list of the services mentioned above that I are currently (macOs 12.2) system wide:

Accessibility
DeveloperTool
ListenEvent
PostEvent
ScreenCapture
SystemPolicyAllFiles

Has anyone found a way to get a list of services? I have services from OneDrive (and more than one account) and would love to be able to querry what those service names are.

Has anyone found a way to get a list of services?

Sadly, there’s still no good way to do this. The bugs referenced in my original post remain unfixed.

I adapted the magic command referenced by: https://recoursive.com/2020/03/03/reset_macos_privacy_permissions/ on Monterey generate the list below.

Hope this helps...

In my case, the root cause was the ownership of the ~/Library/Application Support/com.apple.TCC/TCC.db file was incorrect. This file must be owned by me. Instead it was owned by some other user number.

Do all the stuff that allows you to modify TCC.db.chown the TCC.db to me.Restore all the stuff that prevents you from modifying TCC.db.tccutil reset MicrophonePerform the action in Zoom that caused it to prompt for permission.Say Yes.
