Cannot open Open CPN

Good Afternoon,
I have downloaded the Open CPN program onto my MacBook Pro, and keep getting a notice that I cannot open the program due to it "not being from an identified developer." I tried opening the older and newer versions to no avail. I also looked for it in the Apps file, and it doesn't show up.
Any suggestions would be appreciated.
Cheers,
Tom

Re: Cannot open Open CPN

In Finder|Applications right click OCPN and select "open"

You will need to confirm that you want to execute the program from an unknown developer.

In the Finder, it's located in "devices" and not in the "applications" section. Every time I click onto it, I get that same message. I tried to move it to applications, however it trashed it....hmmmm

Re: Cannot open Open CPN

When you double click the downloaded package - the .dmg - there is a pop-up window (see below).
Drag the OpenCPN into your application folder.

(I see you got it, but just in case..)

Re: Cannot open Open CPN

If you are running Sierra (actually version 10.12.3) on your Mac the GateKeeper of the OS prevent you from installing software not from the Apple Store and/or not signed by a known Apple developer. That is done to keep your Mac clean from malware and other buggy software.

OpenCPN is not signed with a valid developer certificate.

You may have a chance to install it anyhow when you go after seeing the refuse message to the Mac system settings and there to Security. There you might see a button allowing you to install nevertheless to you own risk.

Gerhard,

would you mind to update your private OCPN page with respect to the comments regarding https etc. and the OpenCPN home page?
It does not reflect the actual stage correctly .

Right now one might call the exposed there FUD or interpret it as "alternative facts".

Best regards

Hubert
