I am guessing you are using safari as your default web browser. If so then you need to change settings in safari to show developer settings.
Safari>Settings>Advanced>Show Features for Web Developers
Once you have that selected then you should see options for inspecting the webpage when you right click in the browser.
If you don’t want to do all that then you can change your default browser to chrome. Live server will use your default web browser to open your html.
You are a genius. Thank you! I just changed my default browser to Chrome and it worked right away.
