How to Check the Event Log on PC or Mac?

Event logs are invaluable tools for diagnosing and resolving system issues on both PCs and Macs. They record a variety of events ranging from system errors to security breaches, helping users and administrators keep track of what is happening on their computers. In this guide, we will walk you through the steps of checking the event log on both PC (Windows) and Mac (macOS).

Why Check Event Logs?

Before diving into the steps, it’s essential to understand why checking event logs is important:

  • Diagnosing Issues: Event logs help identify the root cause of system errors and crashes.
  • Security Monitoring: Detect suspicious activities and possible security breaches.
  • Performance Monitoring: Keep track of system performance and optimize it effectively.
