How to enable System Extensions on your M1 Mac?

Modified on: 2023-02-17 10:01:27 +0000

MediaSeal requires the 'Fortium Technologies Ltd' system extension to be allowed in order to function.  In the occasion of a new M1 Mac, the default security prevents installation of third party system extensions and hence you are not prompted to allow MediaSeal's system system extension.  Follow the instructions below to enable system extensions on your Mac M1:

  1. Shut down your Mac device.
  2. Press and hold the Touch ID button for 5 seconds.  Your Mac should boot up showing “Loading up startup options”
  3. Click Options then click Continue
  4. Click on Utilities > Startup Security Utility
  5. Click Startup Disk > Security Policy
  6. Choose Reduced Security, check Allow user management of kernel extensions

However, long term support will not continue with issues on older Operating Systems should they not be resolved within a reasonable time.
