How can I tell if I have a Merlin 1 or Merlin 2 license?
During installation, Merlin 2 copied the license to the local Application Support directory on your Mac (~Library/Application Support/Merlin/Licenses).
The license files for Merlin 1 and Merlin 2 have different file extensions. Merlin 1 licenses have the file extension “.pwreg” whereas Merlin 2 licenses end with “.merlinLicense”. The Merlin Project license files end with ".mprojectl".
If you can’t see the file extensions, right-click the file name and then click “Get Info”.
