MAMP is installed in the typical Mac fashion: very easily. MAMP will not compromise any existing Apache installation already running with your OS X. You can install Apache, PHP and MySQL without starting a script or having to change any configuration files!
Ensure that you have downloaded the latest version of MAMP before following the steps outlined below.
- Locate and double-click the downloaded MAMP ZIP file to extract it's contents.

- Once the contents have been extracted, locate and double-click the MAMP DMG file.

- The mounted MAMP Disk Image will display, click and drag the MAMP folder into your Applications folder.
MAMP will only work if the MAMP folder is located in the Applications folder.
- From Finder, unmount the MAMP Disk Image by clicking the Unmount button.
