I got tasked with updating a company's website. It's an existing WP install and an update will take a few weeks so I don't want to screw around with the live site. I thought about running WP on my iMac and this morning discovered MAMP. But I am reluctant to install software that might put stuff all over my Mac or add to the overhead. (I don't know if MAMP does this but I'm worried it does!) So I'm wondering if there is a way to install something in a Parallels window and run WP there. That way it's all self contained and plenty fast for my Mac to handle. Any thoughts?
