I have been working with sites for many years on windows, just now switching to the Mac OSX platform. Right now I am looking at setting up my local development environment. I looked through a few threads and I am downloading MAMP now. It seems the Mac comes with PHP installed, but it sounded like this keeps it all in a container and deployment was easy. Are there any tricks to getting that up an running? How do you handle developing multiple sites at once, or do you just copy them into a folder and work on them one at a time? What other tools might be of interest? I usually work with WordPress / LAMP based hosts these days.
