Type the following into your terminal (This will return the location of the php ini file being used, once you have the path you will need to open the file - also note the php version being used, this will be important later):
php --ini
- Find xdebug in the php.ini file and add the following (if the zend_extension line has a semi colon ";" remove it):
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_autostart=true

Once this is done you will return to the preferences dialogue, once here search "debug" in the search box and there should be an option to click Debug under: Languages and Frameworks -> PHP -> Debug

Go to your web browser where your site is being hosted locally (for me this is localhost:8888) and refresh the page, if all steps have worked, an "Incoming connection from xdebug" digalog should open in php storm you simply need to click "Accept" you will be able to use xdebug on your site. If this does not work you may need to restart your MAC and try this step again. When you do ensure the connection is still on before trying again (previous step)
