Upgrading MAMP Pro can be a little complicated. Here's the procedure I used to upgrade from 2.0.5 to 2.1.1:
php.ini, etc. make sure to make a backup copy. Easiest way to do this is to go to
Edit Template…and copy the contents of each file. Depending on which version you're upgrading from/to, MAMP may or may not preserve your custom edits.
my.cnf, etc. It will ask you to save your existing ones somewhere else; do that and then use
diff(or FileMerge) to migrate any changes. If it doesn't, you may want to check the new versions against the backup copies you made earlier just to make sure everything is there.
/usr/local/binto the mamp directory; e.g.
sudo ln -s /Applications/MAMP/bin/php/php5.3.14/bin/php /usr/local/bin/php sudo ln -s /Applications/MAMP/bin/php/php5.3.14/bin/phpize /usr/local/bin/phpize sudo ln -s /Applications/MAMP/bin/php/php5.3.14/bin/php-config /usr/local/bin/php-config sudo ln -s /Applications/MAMP/bin/php/php5.3.14/bin/pear /usr/local/bin/pear
Depending on which version you've upgraded to, you may need to relink this.
sudo ln -s "/Library/Application Support/appsolute/MAMP PRO/conf/php.ini" "/Applications/MAMP/bin/php/php5.3.14/conf/php.ini"
sudo ln -s /Applications/MAMP/Library/bin/mysql /usr/local/bin/mysql
