You get this message when you try to launch your newly-installed or newly-updated FontLab VI app on macOS:
“FontLab VI can't be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the mac App store and identified developers.”
You are being stopped by the macOS “Gatekeeper” feature. FontLab VI is not “signed,” and GateKeeper does not like this.
To get around the alert message:
- Find the original FontLab VI app, usually in your Applications folder (not the icon in your dock, if you have put one there).
- Right-click (or Ctrl-click) on the application icon and choose “Open”.
- Then click on the “Open” button at the warning dialog, to launch the app anyway.
This will allow FontLab to continue launching normally until the next time you update it to a new version.
Note: you can permanently disable this type of warning, but we do not recommend it.
FontLab is well aware of how irksome this is. We are investigating the issue.
