I'm on a Mac and loaded MAMP and was running a Lynda.com tutoril and when it show where to load templates in the htdocs folder in mine there is nothing in there. My MAMP app loaded in the app's section of my HD so I guess thats the correct place. Maybe I need help just setting up MAMP before I go any further?
I don't have a mac at the moment so I'm unable to help you with this. Perhaps some other members who do can help you with this
