Using Rosetta

Rosetta is a macOS feature that allows programs written for Intel processors to run on Apple Silicon processors.

Tunnelblick does not need Rosetta; it is written to run on both Intel and Apple Silicon processors.

If you previously turned on "using Rosetta" for the Tunnelblick application, you can turn it off:

  1. Quit Tunnelblick if it is running.
  2. Open a Finder window with /Applications displayed.
  3. Control-click on Tunnelblick, then click "Get Info".
  4. In the new window that appears, remove the check in the box labelled "Open using Rosetta".
  5. Close the "Get Info" window.
