unidentified developer error

[rnumon]

Just updated my opencpn sw to 5.01 for mac os. Tried to open the app and am getting a dialogue box saying the app can't be opened because it's "from an unidentified developer"!!! I can't get to anything - pls help!!

Instead of double-click to launch right-click and select "open" and when requested with the warning about all the bad that might happen, allow to launch.

This a "one-time-action" for not-registered-by-Apple software..

Thank you. Suggested action didn’t work but led me to my security settings where I set it to open all apps, not just those that are Apple. That seemed to work.
