I just happened to find your post as I was going thru my own hell of trying to get WordPress to work on my MacBook Pro. I found this video tutorial: http://css-tricks.com/video-screencasts/86-mamp/ which led me to try just typing in: http://localhost:80 (since that is the port I chose to set up my MAMP in) and all of a sudden it loaded the WordPress home page saying that it installed!! Try it and see what happens. If that doesn’t work, try watching the video – it seems pretty helpful!
