Hi,
I don't have a Mac here to test, but the steps in the wiki are not exactly windows-specific, it works the same on Linux or Mac. Just that paths look different, you start a terminal differently and you run `php` instead of `php.exe`.
"I already have php". Great. Have you found and adjusted the php.ini file? On linux it would be somewhere like /etc/php/php.ini , probably the path is similar on a Mac.
Have you started php with the webserver option? Like
php -S localhost:8000
On Mac and Linux, executables don't have the '.exe' extension, so you run 'php' instead of 'php.exe' .
Maybe I will do a Linux version of the wiki page.
Greetings,
Christopher
