+When you attempt to launch the console, you may be presented with a message that says the developer is not verified. DO NOT click "Move to Trash" - this will delete the files necessary to run the graphical console. Once you get this message:
 
 - Open `System Preferences` -> `Security & Privacy` -> `General` Tab and click `Allow Anyway` next to the message about the jnlilib that was blocked.
 - At this point you can try the `Launch KVM Console` button. You should be presented with another dialog about developer verification. Click the `Open` button.
 - This will trigger another denial window for the sharedLibs jnlilib. Repeat the approval process for this next jnlilib in the `Security Preference` Pane.
 - After performing these two approvals, the console should open.
