I want to install VAPOR on my Mac computer but I had this error message " **“vapor” cannot be opened because the developer cannot be verified.**

Is there any idea to solve this problem?

Yes, this is bothersome.

If you right-click on the Vapor icon, then click Open, the dialog will have an option for you to open it anyways.

After you do this once, you shouldn’t need to do it again.

There is no such an option!

Make sure you are **right-clicking** the vapor icon, and then clicking open. Not left-clicking. Left-clicking the icon will block the application without giving you a bypass option.
