macOS and the Camtasia System Audio Capture Component

Problem

When installing the System Audio Component the install fails. Recording system audio on macOS 11 (or later) with Camtasia results in an error message, distorted audio, or no audio at all.

Please make sure you are running the latest version of Camtasia. From the menu bar, select Camtasia > Check for Updates to install the latest version.

Option 3: Remove Old Plugin

  1. Quit Camtasia and the System Preferences.
  2. Open a Finder window.
  3. Select Go > Go to folder from the menu bar.

  5. Delete the ACE.driver folder.
  6. Restart the computer.
  7. Install the system audio component through Camtasia.

Option 4: Re-Enable Component

If macOS still fails to show the correct prompt to authorize the ACE component for use, you’ll need to manually authorize it. This is done by entering the Mac's Recovery mode.

  1. To enter the Mac's Recovery mode, follow Apple's instructions for Intel or for Apple Silicon.

  2. Once booted into Recovery, open the Terminal utility and enter the following commands pressing return after each one:

    spctl kext-consent disable
    spctl kext-consent add 7266XEXAPM
    spctl kext-consent enable
  3. After entering those commands, restart your Mac.

  4. Follow the steps to reinstall the component through Camtasia.

Once ACE is properly authorized and installed it can be uninstalled and even reinstalled, without requiring any further system-level authorization.
