Any suggestions?


Hi Tim.


You have just encountered “The Gatekeeper” which Apple use as protection against nasty software.


It crops up on here occasionally, but don’t worry you can over ride the settings.


Full details here:


Good Luck.

Thanks, @datacommando! I've been on Catalina since it launched and hadn't seen a dialog like that before.


For posterity, this is what I did to fix it:

  • Open the .pkg file to get the error dialog
  • Open System Preferences > Security & Privacy > General tab, then click the "Open anyway" button
  • Another warning dialog appears; click "OK" 
  • The installer should then open
  • Thanks 1
