Create a PowerShell shortcut on MAC

Question

Hi All, Not sure where to go with this one. I created a script to sit on the desktop and allow end users to run stuff like testing port connectivity or nslookup that tech would ask over the phone. Gives a menu. What I'm trying to do now is create a shortcut to the script on Mac as I was able to do in Windows. Click on the dock as you would in taskbar and script launches. Script runs fine on Mac problem is the shortcut, anyone have thoughts on this one? I know cross/os idea. Thanks
