I just upgraded my Mac Operating System and am getting errors 2100 or 2110

A 2100 error occurs when our license is unable to be saved.

This is a result of the Mac OS changing the permissions on our DFX licensing folder during a major operating system update. To resolve the problem, please follow the instructions below.

  1. Uninstall the DFX software by going to /Applications/Tiffen/ProdcutName and running the Uninstall program.
  2. Go to /Macintosh HD/Library Application Support.
  3. Delete the Tiffen folder.
  4. Install the Tiffen software and activate it using Internet Activation.



Recent changes to Mac OSX 10 required that we modify our license manager. This affects activating and deactivating.

If you receive a 2110 error, please follow the manual install for the license manager below.

Manually install the license manager

- Download the license manager from: HERE
- Double-click on the file that is downloaded.
- When the window opens, double-click on the FxLicenseManager.pkg and run through the install process.
- Start the Digital Film Tools software and try activating using Internet Activate.
