Which of the following log files in a Mac system contains information related to network interface history?

The correct answer is that network interface history on a Mac system is primarily recorded in the log file located at /var/log/system.log. This log file contains various system messages, including those related to network events like connections and disconnections, which provide a historical account of the network interface activity.

While /var/log/messages is not typically a standard log file on macOS but may exist in some Unix-like systems, it generally serves a similar purpose but is not the specific log for macOS. /var/log/daily.out typically contains output from maintenance scripts that run daily, such as system maintenance tasks but does not specifically log network interface history. /var/log/network.log is also not a standard log file in macOS systems; while it may seem logical, this file does not exist as a primary source for network logs on macOS.

Understanding the specific role of /var/log/system.log in macOS ensures that you can locate pertinent information regarding network changes and issues, which is vital for troubleshooting and forensic purposes.
