Mac Crashed? Here's How to Check Why Your Mac Shut Down and Fix It

Did your Mac crash out of nowhere? Whether your MacBook shut down, froze, rebooted, or showed a sudden MacBook crash screen, this video explains why it happened and how to prevent it from happening again.

In this guide, we break down the most common reasons a MacBook or iMac might crash, from outdated or conflicting apps to hardware problems, overheating, kernel panics, and even malware. If you’ve been asking “why does my Mac keep crashing?” or trying to figure out how to check why my Mac crashed, this walkthrough will help you understand what’s really going on behind the scenes.

We’ll show you where to find crash reports using macOS Console, how to interpret spin reports and system logs, and what they can tell you about unexpected Mac shut down or MacBook shut down events. You’ll also learn practical troubleshooting steps like booting into Safe Mode, updating macOS and apps, checking Activity Monitor for resource-heavy processes, and knowing when a crash may point to a deeper hardware issue.

While malware isn’t the most common cause, it can contribute to instability — which is why running a full system scan is an important step when diagnosing repeat crashes.
