I\'ve spent some time trying to figure out why the autostart, remote , and connect_back settings wont turn on. I\'ve typed in:
xdebug.remote_enable=1 xdebug.
This is super late, but, you need to edit the correct php.ini file. MAMP comes with 2 or more!
From the MAMP control/app launch the PHP_INFO() page, or make your own. Check the path value for the Loaded Configuration File
Loaded Configuration File
That is the php.ini to edit.
