I made a very simple application using Automator to "Get Specified URLs". I saved it as an application on my desktop, but whenever I click on the icon to open the application, it does not run. No dialogs or errors were returned. I am using High Sierra, which is the OS my computer was shipped with (no recent updates) What might be the reason behind this?
In order to make the URLs open upon launching of the app, you will need to add the "Display Webpages" action to display the webpages you have chosen.
