Where would you look for configuration files on an Apple computer?

• A. /etc
• B. /var
• C. /usr
• D. /opt

Answer: (A)

On Unix-like systems, configuration files that affect the whole system live in /etc. On macOS, /etc is the standard spot for many global settings (for example, hosts, ssh_config, and other service configurations), and it’s actually a link to /private/etc, so either path points to the same place. The other directories have different roles: /var holds variable data like logs, /usr stores programs and libraries, and /opt is for optional software. So the place you would look for configuration files on an Apple computer is /etc.
