How do I do a complete uninstall and re-install of MAMP PRO?

Sometimes it is necessary to completely uninstall and reinstall MAMP PRO.

To completely uninstall MAMP PRO use the following steps:

  1. Write down your Apache, MySQL, and DynDNS port numbers. They are located on the "General" Tab. Some Content Management Systems are port-dependent.
  2. Back up any host files that are located in the "/Applications/MAMP" folder. It is best not to keep host files in your "/Applications/MAMP" folder, a better location would be "/Users/MyUserName/Sites".
  3. Back up your databases. They are located in "/Library/Application Support/appsolute/MAMP PRO/db". These files, if not backed up in a safe location, will be erased by the MAMP Uninstaller.
  4. Use the Uninstaller located in MAMP PRO, with MAMP PRO open, go to the menu, MAMP PRO > Uninstall. This will completely uninstall MAMP and MAMP PRO.
  5. Throw your "/Applications/MAMP" folder in the trash.
  6. Download a new version of MAMP PRO and install it.
  7. Set your port numbers back to your previous port numbers.
  8. Copy back your database and host files to their original locations if needed. You will need to remake your hosts.
