How to set up Apache to start automatically on macOS boot

Running a web server on your local machine can be incredibly useful for development, testing, or even hosting personal projects. Apache is a popular web server software that runs on macOS. While macOS comes with a version of Apache pre-installed, it doesn't automatically start upon booting the system.

For developers or administrators who frequently use Apache on their macOS systems, it can be convenient to have Apache start automatically every time the system boots up. This ensures that the web server is always available without manual intervention.

macOS uses the launchd system process as its init system, which initializes other processes. macOS already has a launchd service definition for Apache. To make Apache start automatically, you'll need to load it using launchctl.

Steps to automatically start Apache during macOS startup:

Launch Terminal application.
Check if current Apache configuration is valid.

  501  4473   161   0 Tue07AM ??         0:01.17 /usr/sbin/httpd -D FOREGROUND
  501  4474   161   0 Tue07AM ??         0:01.06 /usr/sbin/httpd -D FOREGROUND

Use launchctl to load Apache's service and ensure it starts on boot.

$ sudo launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist
Password:

Disable Apache from automatically starting up during system boot when no longer necessary.
```
$ sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist 
```
