When trying to connect to a Firepower 1010 ASDM I was met with this;
“Cisco ASDM-IDM.app” cannot be opened because the developer cannot be verified.
macOS cannot verify that this ap is free from malware
If you’ve spent much time using macOS then this is quite common, Open System Preferences > Security and Privacy > General tab > You will see a warning about the Cisco ASDM-IDM > Click ‘Open Anyway‘.
If you are prompted again simply click ‘Open‘.
