What are system log files?
System logs capture the activity of system applications and services. These system log files can be sent to developers for debugging purposes if an application crashes. But sometimes these logs, which are typically smaller files, can end up with a lot of information and start taking up tons of space. Luckily, if you're not one to send app crash reports, you can clean up these system logs to help with app performance and save your Mac some space.
