Xdebug not stopping on breakpoint on MacOS High Sierra although is correctly installed

My development environment is: - MacOs High Sierra - PhpStorm - PHP 5.6 - Apache 2.4 - Xdebug 2.5.5

php config file for xdebug:

[xdebug]
zend_extension="/usr/local/opt/php56-xdebug/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_mode=jit
xdebug.remote_autostart=1
xdebug.remote_handler = dbgp
xdebug.force_display_errors=1
xdebug.idekey="PHPSTORM"
xdebug.remote_enable=1
xdebug.show_error_trace=1
xdebug.remote_log="/Users/user/www/xdebug_remote.log"
xdebug.profiler_enable=0
xdebug.profiler_output_dir="/Users/user/www/xdebug_profiler"

In PHPStorm debug validate tool it seems everything is up and running:

The xdebug debug log is

To run in debug mode I follow those steps.

I can't figured out why the breakpoints aren't hit. Anyone can give me some hints?

It's not PhpStorm that is listening for port 9000, most probably it's php-fpm. Change the debugging port to 9001 in PhpStorm and the .ini file.
