There’s nothing more disturbing than your Mac restarting time and again. When there's a system-wide crash in your Mac, you get a warning signal to restart your computer. It's like a windows PC' blue screen of death where you cannot run any application unless you restart it. This situation is called kernel panic.

Kernel panic affects your work progress and indicates the underlying software/hardware problems in your system. If you don't deal with them timely, a more prominent issue will soon knock your Mac down.

In this guide, I'll tell you about the ins and outs of kernel panic, its causes, and how you can deal with it at home. So, just keep reading.

What is A Kernel Panic on Mac And What Causes It?

When a Mac system’s underwired circuits do not properly function, it initiates a kernel panic. Most systems face this problem once or twice a month, which is not that horrifying. 

But when your computer cannot function without at least 2-3 restarts, it’s a serious kernel panic in there. You need to solve it soon because delaying it can further damage your software/hardware components. Following are the few main culprits of kernel panic:

  • No space on RAM and hard drive
  • Outdated plugins
  • Incompatible peripherals
  • Broken discs and permissions
  • Conflicting apps and programs 

Although there can be many other reasons for your Mac facing kernel panic, these are the few major ones that need to be sorted out. If your system is slowing down because of this panic or showing abrupt connectivity issues, it’s time for you to take action.  

Here we go! How to Fix Kernel Panic Error on Mac?

No worries if your Mac is affected by kernel panic because it can be pretty much fixed at home. There are several ways to complete this task, each with a separate target component. Let’s start with them: 

Tip 1 Ensure you have enough space on the hard drive

As we can see, having not enough space on RAM and hard drive is one of the main reasons of kernel panic on Mac. Having sufficient space on the hard drive maintains your computer’s speed, along with preventing the kernel panic. Hence, it’s advisable to regularly clean up the cache, history, downloads, and other unimportant files from your macOS. 

How to free up maximized space on your Mac? The easiest and most effective way is to use a Mac cleaner app. And Umate Mac Cleaner is a great choice with 100% work cleanup features for you. It quickly cleans up your system and provides 4x more space than regular cleanups. Also, this pro tool offers a quick scanning feature to determine which apps/files must be deleted from your macOS.

Tip 2 Restart your Mac using safe boot

This is the easiest way to stop kernel panic and complete the task you were previously doing. To smoothly operate your macOS, open it with the safe boot, and prevent kernel panic from messing with your activities. Here’s how you do it:

  • First, shut-off your computer, and let it rest for a few seconds. 
  • Now, start it. But when your macOS is booting, press the “shift” key till it loads. 
  • This will open the safe mode in your Mac where the hardware/software issues aren’t prevalent.  You can log in to your account within seconds and hold this panic for quite some time.

Tip 3 Update all your softwares

When your macOS runs old and outdated software, it often gets slow and causes the kernel panic. To stop that, make sure all your software is updated.

  • Go to the Apple app store, open your apps, and see how many of them need upgrades.
  • If you see a popup saying update these, click it and quickly update your apps. 

This process takes a few seconds and is done by a click-through method to update Mac systems.

Tip 4 Find which apps are corrupted

Several heavy apps hinder your system's speed and need repetitive upgrades to stay functional. If there is a particular app that causes kernel panic on Mac every time you open it, it's easier to overcome it.

Try updating that app and see if it stops corrupting your system. Alternatively, delete and reinstall that app to ensure the smooth operating of your macOS.

If identifying the corrupted app is difficult for your system, emphasize those that came through external peripherals as they often have malware or broken links in them. 

Tip 5 Check kernel panic logs

Since kernel panic is common in Mac systems, you get access to a whole log that determines which kernel is the faulty one. 

There are multiple kernels (operating units) in a system, which must be regulated. When you open these kernel's log, you see which one has an issue and resort it accordingly.

To check your system’s kernel log, click “finder” and open “diagnostic reports."

These diagnostic reports come in the form of a drop-down arrow. Select "kernels" from the list and read through the resulting page. This will pinpoint the faulty kernel so that you can get it fixed.

Tip 6 Run disk utilities

Several computer errors originate from external devices because of the malware associated with them. Luckily, you get a disk utility option in Apple laptops that test your Mac’s drivers beforehand. 

If you want to test disk utility, restart your computer. Press R+Command while it restarts as that’ll launch the first aid window. 

Go to the disk first aid window and see if it points towards any problem. If there is, troubleshoot it, and it'll most likely fix your disk.

Tip 7 Reinstall macOS

An older version of macOS can also result in a kernel panic, which is easily fixable. Once you see the kernel log, you'll know if the panic is because of the macOS or something else.

If the diagnostic report confirms that your software is faulty, open the computer's utilities and click the "Reinstall macOS" option."

This will take a few seconds and start reinstalling a newer version of macOS, eventually stopping kernel panic.

Tip 8 Check peripherals

External devices often contain malware and viruses which affect your system. If you’ve recently changed a printer/USB/SD card and started seeing kernel panic after that, the answer is evident. 

Eject any peripheral associated with your Mac and reboot it. Most probably, you won't see a kernel panic this time.

Tip 9 Disable startup apps

When you start your Mac, there are 10s of apps which open with it. Sometimes, it's hard for the processor to handle these many apps, and it simply quits.  

  1. To uproot this issue, go to your computer’s “user preferences” and open your login option. 
  2. This will lead you to the login startup apps. Click the unnecessary ones and disable them by hitting the “-“ button in front of them. 
  3. This will take some load off your processor and enhance its speed. But, if you want to know which of these apps is causing kernel panic, enable them one by one and see when does your system crash. 

If it crashes upon enabling a particular app, that one is the culprit behind kernel crash on Mac. 

But this process will take a lot of time. If you want to disable these startup apps in a jiffy, try Umate Mac Cleaner. This smart tool will disable the background apps with one click and improve your computer’s speed alongside. The program can automatically detect and show all the startup items on your Mac. You can disable these startup items within 1 click or disable one by one accordingly.

Tip 10 Run Apple’s Hardware Test

Macs have built-in hardware tests that analyze the logistics and pinpoint the flaws. To run a hardware test on your macOS, restart it. 

While it reboots, press D. This will start Apple diagnostics so that you get a clear report about what’s wrong with your computer. 

This report is quite easy-to-understand and will answer most of your questions. If you can't decipher the problems, contact Apple Support, and share the diagnostics with them.

Tip 11 Uninstall applications on your Mac

Unused applications affect your Mac's speed and might initiate a kernel panic too. If you have several applications in your macOS, uninstall them and see if that stops kernel panic.

If it does, install your required apps one-by-one and notice which one disturbs the speed and crashes it. 

However, this can be a hectic process i.e., uninstalling and reinstalling those apps. But don't worry because Umate Mac Cleaner offers a one-step app uninstallation.

You can get rid of many apps at once and save your time. Also, this Umate Mac Cleaner secures your privacy so that you use it confidently.

Tip 12 Format and install macOS

If none of the above-discussed tricks stops your system’s kernel panic, it’s time for you to work on the macOS itself. 

This means removing all data from a computer and replacing its operating system with a new, fresh alternative. Luckily, this doesn't take much time, and you can do it by following the on-screen commands.

Make Sure to Maintain Your Mac Clean and Prevent Kernel Panic Again

A packed Mac can have kernel panic any minute, without any prior indication. To stop this nuisance, optimize your system’s configurations and maintain a sufficient space in it. 

Use Umate Mac cleaner to delete unnecessary files, uninstall those hardly-used apps, and clean the cache from your Mac. This will clear up some space in your Mac’s hard drive and stop kernel panic from disturbing you.
