How to Fix Painc Medic Boot on MacBook Pro, MacBook Air, iMac, etc.?

Hi there. I am a super noob so please have patience with me. I am a songwriter and have my computer for one purpose, writing music. I use a program called Logic X and until today I have had no problems with my Mac mini M1 2020 running Big Sur. For some reason, my computer keeps on restarting, with "Panic Medic Boot" showing up before restarting again. Tried reinstalling Big Sur but it says it doesn't have enough space on Macintosh. I have precious files on this computer that are not backed up. Can somebody please help me? I would appreciate any help. Thanks again.

If you're one of the users who receives this Panic Medic Boot notification saying "A third party kernel extension was preventing the machine from successfully booting. All third party kernel extensions have been disabled. You will be prompted to re-enable them in the Security & Privacy System Preferences pane as they are used.", you have clicked in the very post.

This Panic Medic Boot leads the Mac to restart and boot continuously, preventing the machine from logging into the user interface successfully.

This post walks you through fixing this annoying popup and dealing with the app that triggers such an error notification. Let's get started then!

How to fix Panic Medic Boot on Mac?

Being interrupted by a continuous Mac Painc Medic Boot notification is not a pleasant experience, especially when you're busy with some creative or editing business. Luckily, you can terminate this notification by entering macOS Recovery Mode and executing certain commands in the terminal utility. 

We will guide you through the whole process and you just need to follow this tutorial step by step. Attention should be given when running commands as any slight error may cause trouble to your machine, reducing it to work improperly.

Step 1: Boot your machine to macOS Recovery Mode

Steps to boot into macOS Recovery Mode vary based on the Mac models. So, you ought to check your Mac model via the Apple menu > About This Mac > Overview, then you can tell whether you're running an Intel-based processor Mac or an Apple Silicon chip Mac. 

Follow the steps below to start your Intel-based Mac in macOS Recovery Mode:

Here's how to boot an M1/M2/M3 Mac in macOS Recovery Mode:

Once you're booting into the macOS Recovery Mode, you can launch Termina to run the commands to stop this "A third party kernel extension was preventing the machine from successfully booting. All third party kernel extensions have been disabled. You will be prompted to re-enable them in Security & Privacy System Preferences pane as they are used." message.

This action will delete and disable the loading of third-party kexts to safely boot into the target volume.

If you successfully disable this popping Panic Medic Boot notification with the help of this page, then share your happiness with your families and friends.

How to fix the problematic software on Mac?

If you need to cooperate with this culprit software for further work, you may have to uninstall and download it one more time since its kexts perhaps go wrong after this troubleshooting. Or, if you find this app redundant, you'd better uninstall it from your workstation to prevent it from causing trouble any longer.

A simple drag-to-trash move is less recommended here as manual deletion never removes an app and its associated extensions, packages, and files completely. It's software developers' common behavior to deeply plant some app root files or packages on a Mac hard drive to induce you to install it again. On top of that, these leftovers would conflict with the OS and take up hard drive space without notifying you.

Thus, a professional app uninstall - iBoysoft MagicMenu comes here to help. This professional utility exceeds itself from other uninstallers and workarounds for its one-in-all and amazing uninstall feature.

Specifically, it gathers all associated files of an app before the ultimate uninstall, including user files, caches, preferences, install packages, extensions, root files, junks, etc. Once iBoysoft MagicMenu finishes the file gathering, you can choose what files to delete along with the uninstall once and for all, which greatly saves time and effort in searching for the files scattered in different folders and directories.

Here's how to uninstall the app that results in such a Panic Medic Boot issue on Mac:

Step 1: Click the Free Download button below to install iBoysoft MagicMenu on your Mac.

Step 2: Launch this handy app uninstaller and search the Uninstall extension in its main window to download it. Note that iBoysoft MagicMenu only takes a little space and so does the Uninstall function, which nearly does not influence your Mac.

Step 3: Go to Finder > Applications, locate the unwanted app, then right-click it to select Uninstall from the dropdown menu. (This post takes ZeroTier as an example and the steps to remove the corrupted app are the same.)

Step 4: Wait for this professional app remover to gather all associated files of the will-be-uninstalled app. Once it finishes, check the useless files to let them be removed along with the app.

Step 5: Click Uninstall to confirm your actions and initiate the uninstall progress. This progress may take up to several seconds.

Once the app is removed along with its kext extensions or packages, you can access its website page or developer to download one more time.

Notes after fixing the Panic Medic Boot on Mac

There is no end of sorts of bugs, errors, notifications, or messages triggered by software or hardware, yet the essence of using a Mac or Windows computer is to back up all your files all the time. 

Backup matters most especially when the Mac will not turn on, the Mac gets dead, the Mac shows a black screen, etc., halving your anxiety and ensuring you try kinds of solutions without considering data.

The 3-2-1 backup strategy is highly welcomed and works in this way:

• 3 copies: Keep three copies of your data, including the original, and at least two copies.
• 2 different media: Store the data copies on two different devices or media types.
• 1 copy offsite: Keep one copy offsite to prevent data loss due to a site-specific failure.
