These packages contain Moodle plus all the other software needed to make it run: Apache, MySQL and PHP.

The downloads were built by Ralf Krause using the distributions of XAMPP and MAMP. It is almost trivial to install with a nice little control application. Also, they include a special git update script, so it's very easy to update your Moodle without needing to download the whole package again and without reinstalling all your courses. XAMPP and MAMP work with Mac OS X 10.6, 10.7, and 10.8.

Moodle4Mac is designed for developing and testing locally on an Apple computer. You need to make it more secure if you will open Moodle4Mac for an intranet or for the internet. Please remember this fact! For your better information you should look into the package documentation.

If you're looking for a Mac Server installation then you should read the step by step installation on a Mac OS X Server.
