If a Toon Boom application is installed AFTER upgrading to Sierra, it won’t be possible to start the application because of the new security mechanism in the OS.
If a Toon Boom application was installed BEFORE upgrading to Sierra, it will start with no issues.
If you install an application AFTER upgrading, you can run the following command in the Terminal to allow running Toon Boom applications. You only need to disable it the first time the application is started:
sudo spctl --master-disable
Once this command is used, the anywhere option will appear in the system preferences in "Security & Privacy > General” and you will be able to start Harmony by right-clicking it and selecting "Open”.
To reenable the security as it is in the default state, simply change the "Allow apps downloaded from" to "App store or identified developers" from the System Preferences. This will re-enable the security.
You can also run:
sudo spctl —master-enable
And you can use:
