MAMP Pro and Drush mem exhaustion
n.b. The error message says that your memory limit is 32MB, not 128MB.  The 128MB setting must be for your web server.  Check the php.ini for PHP CLI; it's quoted in the output of Drush status, above:  /Applications/MAMP/bin/php/php5.4.10/conf/php.ini.  You should find that memory_limit is 32M, or perhaps unset.  Set it to 128M, or perhaps even 256M or more, and you should be fine.
