how to transfer wordpress site from mamp on my desktop to mamp on my laptop

I just want to transfer wordpress from my desktop to my laptop so I can contine developing it. I thought it would be as easy as using the export/import tool. I have a fresh Mamp and wordpress all ready to go on the laptop but wordpress is asking me to use a plugin that wants ftp info to import my xml file. I am not importing from an established blog just computer to computer. So how is this done?
