Some time ago I installed Apache 2.2.29 with this manual: https://echo.co/blog/os-x-1010-yosemite-local-development-environment-apache-php-and-mysql-homebrew into this directory: /usr/local/Cellar/httpd22/2.2.29/bin/httpd Yesterday I installed Apache 2.4.17 with this manual: https://www.youtube.com/watch?v=hV52Vs4E1xs into this directory: /usr/local/apache2/bin/httpd Terminal command which httpd shows me this: Server version: Apache/2.2.29 (Unix) is there any way to switch to 2.4.17? (I'm on OS X 10.10.5)
