If you've received a pop up message stating "Unidentified Developer" or " “VSCO Film” is damaged and can’t be opened. You should move it to the Trash." during installation here are the two options you can choose to bypass this.
As it turns out, Mac defaults to preventing applications from unidentified developers or sources from being launched.
There are two ways you can resolve this.
If you'd like to bypass this message once:
- Right-click (or control-click) the application in question and choose “Open”
- Click the “Open” button at the next dialog warning to launch the app anyway
You can do this with any third party app that gives you this warning dialog and open it anyway.
To disable GateKeeper’s Unidentified App Developer Prevention Completely:
- Launch System Preferences from the Apple menu
- Choose “Security & Privacy” and then click the “General” tab, followed by clicking the lock icon in the corner to unlock the settings
- Look for “Allow applications downloaded from:” and choose “Anywhere”
- Accept the security warning and allow
You can now launch any app from any location or developer.
