If you, like me, like to define your own VirtualHosts, and don’t like re-defining them every time you upgrade MAMP, there’s a solution. Store your virtual hosts in a separate place, and then just include them in the MAMP httpd.conf. Since Macs have Apache built in, I store all my custom VirtualHosts in:
/private/etc/apache2/extra/httpd-vhosts.conf
Edit MAMP’s apache configuration file located at:
/Applications/MAMP/conf/apache/httpd.conf
..And append the following line at the end:
Include /private/etc/apache2/extra/httpd-vhosts.conf
Then restart MAMP, and you’re done!
