Brew says it installed and to look at phpinfo() to confirm.
Neither phpinfo() nor get_loaded_extensions() shows Phalcon to be installed.
Your documentation for Mac OS install still includes PHP5.x Are there current installation instructions available?
i think this is what mac users are using, zephir has some issues on mac i think
it simple i think, just install the php71 phalcon:
brew install php71-phalcon
then run the php71-phalcon as administrator:
sudo brew services php71-phalcon start
then serve website using php builtin server:
php -S localhost:port -t /public .htrouter
