If the user fails to allow/approve the KEXT consent prompt, TMSM will not work properly. To fix this issue, follow the steps below:
- On the "System Extension Blocked prompt, click on Open Security Preferences. This will open the Security & Privacy window.
- Under the General section, click on the Allowbutton.
- Reboot the computer to apply the changes.
The "Allow" button will disappear automatically if not acknowledged within 30 minutes. It will appear again once the KEXT is re-loaded by restarting the Mac.
