Google Chrome Canary app fails to open I have Google Chrome Canary app installed on a MacBook Air running macOS High Sierra. When I click on the app icon in the Dock, it bounces once and then never opens.

Has anyone else run into this or knows how to resolve it?
I think the icon in the doc is not for the Canary app you just downloaded. The icon in the dock should be an alias to Canary. I would drag Canary from your Applications folder to the dock. This will create a new alias for the version of Canary on your machine. Try this new dock version to ensure it works. If so, delete the older icon from the dock.
