I was setting up an ATG development environment and had installed a version of MySQL that was known not to work with ATG..(oops..I’ll cover this in another posting). I uninstalled MySQL using the following steps :

  1. cd /usr/local
  2. sudo rm mysql
  3. sudo rm -rf mysql-<some version number here>

With this done I downloaded a different version of MySQL and tried to install it, however I received the following error.

“You cannot install MySQL blah-version-blah for Mac OS X on this volume. A newer version of this software already exists on this volume”

After digging around about this for a while I was finally able to come up with the problem. You need to go into the /Library/Receipts directory and delete the Mysql related items in there was well. An example :

  • cd /Library/Receipts/
  • rm -rf Mysql<blah blah blah>

With this done. I was able to continue installing the new version and get back to stuff. Hopefully this helps someone else.
