What is Kernel Panic on a Mac and How to Fix It? [Updated for 2024]

There are two major system errors that users fear the most; one is System Failure, and the other is Kernel Panic. When using a Mac, there is a possibility that you might encounter a Kernel Panic error. Kernel Panic on Mac is a system malfunction where a critical system issue compels the system to restart. If the issue persists after the reboot, your Mac will continually restart.

This article delves into the topic of Kernel Panic on a Mac, exploring its causes and potential solutions in depth. Read through to the end to effectively address this issue on your Mac.

What is a Kernel Panic on a Mac?

Kernel Panic is a safety mechanism implemented within an operating system's kernel, activated when a critical error is detected that the system cannot recover from. This typically happens when the kernel identifies a situation where proceeding with normal operation would potentially cause severe damage to the system or lead to substantial data loss. Upon a Kernel Panic, the system is forcibly restarted.

During a Kernel Panic on a Mac, the user's screen will turn black, displaying a warning message in various languages. Typically, it begins with the phrase, "You need to restart your computer." The system will then either await the user to initiate a restart or automatically reboot itself. If the underlying issue remains unresolved, this rebooting process may persist in a loop, which can be a significant problem.

Causes of Kernel Panic on Mac

If you're seeking the reasons that can lead to a Kernel Panic, the answer is that there are numerous factors at play. A wide range of reasons can cause a Kernel Panic, with over 90% of instances typically attributed to software issues on your Mac. Here's a list of some common causes behind Kernel Panic on a Mac:

1. macOS Issues: The operating system of your Mac might trigger Kernel Panic if it hasn't been updated in a while. Alternatively, an improper update could also lead to this issue. To fix this, you'll need to update your macOS or reinstall it.

2. Outdated Apps: If the Kernel Panic occurs specifically while using certain applications, they might be outdated and require an update. It's advisable to update these apps or reinstall them if the problem continues.

3. External Devices: Kernel Panic can also occur if the external devices connected to your Mac are incompatible. A corrupted or damaged external device can also trigger a Kernel Panic on your Mac.
