localhost

Is the webserver running?

Do you get an error? If so what is it?

Did you start up the apache server?

What is the output of the OS X Terminal command

netstat -an | grep LISTEN

Here is an example....

netstat -an | grep LISTEN

tcp4 0 0 127.0.0.1.50989 *.* LISTEN

tcp4 0 0 127.0.0.1.50986 *.* LISTEN

tcp4 0 0 127.0.0.1.60012 *.* LISTEN

tcp4 0 0 127.0.0.1.60010 *.* LISTEN

tcp6 0 0 ::1.5001 *.* LISTEN

tcp4 0 0 127.0.0.1.5001 *.* LISTEN

tcp4 0 0 127.0.0.1.5003 *.* LISTEN

tcp4 0 0 127.0.0.1.60014 *.* LISTEN

tcp4 0 0 127.0.0.1.29754 *.* LISTEN

tcp4 0 0 127.0.0.1.1023 *.* LISTEN

tcp4 0 0 *.88 *.* LISTEN

What port are you using? MAMP does not use port 80 so you need to read the manual (or check MAMP's settings) & check you have the correct port.

Stuff that into Safari…

http://127.0.0.1:8080 or whatever.

You may prefer to use localhost or your 'computer name' instead of 127.0.0.1.

Have you reviewed MAMP's logs? It normally records failures if you dig into it. Also check you have the latest version.

Can you use the settings as described in the documentation and Drew Reece 's suggestion?

It is still not clear if you are specifying a port - do you understand what this means?

Please examine the MAMP settings & confirm exactly what the Apache port is - please post that information here.
