Technical problems are frustrating, and troubleshooting issue is time-consuming. When your MacBook Pro keeps shutting down on Startup, you can't just ignore the problem. You're dead in the water. You need a solution immediately. So, instead of throwing the computer out the window, let's take a look at what could go wrong. Then, we'll go over tips for fixing your computer and making sure it never happens again.

Part 1. Why MacBook Pro Keeps Restarting?

You're wondering: "Why does my MacBook Pro keep restarting?" The answer is that when you install new software solutions on your MacBook Pro, it can lead to "kernel panic" (or KP) which leads to unexpected restarts. A kernel panic is really not as scary as it sounds. When your computer's OS encounters an internal fatal error on bootup, and it can't safely recover or continue, it will display an error message informing you that it needs to reboot.


There can be many reasons why your MacBook keeps rebooting.

  • The most common issue is conflicting applications.
  • Another issue could be incompatible hardware or peripheral devices.
  • It could be an issue of not enough RAM or hard drive space.
  • The plugins or drivers could be out-of-date.

When your MacBook keeps restarting, this is what happens:

  • The system detected a problem and it gives an error message that it must restart to fix the issue.
  • If the system is truly stuck in the reboot cycle, the system will shut down.
  • In general, a message will pop up on your Mac screen showing you "Your Computer restarted because of a problem."

Part 2. How to Fix "Mac Keeps Restarting"?

So, by now, you have an idea of why your MacBook keeps restarting, but how do you fix it? Take a systematic approach to troubleshoot, starting with the hardware. As you test the potential suspects, you can cross them off your list and move on to the next possibility.

Issue 1: Hardware Conflict:

The kernel panic can be caused by hardware conflicts. So, if you've recently installed new RAM, a hard drive, a printer, or other devices, the addition(s) may be contributing to the problem


Solution: Check the devices and hardware hooked up to MacBook Pro

1. Turn off your MacBook Pro.

2. Disconnect all devices including printers (excluding the display, mouse, and keyboard).

3. Restart your MacBook.

4. Use your MacBook for the period of time that would typically have resulted in a restart.


Issue 2: Software Conflict

Problems can pop up when you install new software on your MacBook Pro. There could be a compatibility issue, or it could be that the lack of space on your hard drive is contributing to the problem, and making it appear that your issue is software related.

Solution1: Check the software installed on your MacBook Pro

1. Hold down the Shift-button and boot into Safe mode.


2. Back up your user files to an external hard drive.

3. Update the software on your MacBook Pro.


If the problem persists and is not resolved with the reinstall of your software, it may be a recurring issue with corrupt software. It's not uncommon to be required to reinstall your software, so it's important to make sure you're regularly backing up your system.

Solution 2: Discover corrupt software

1. Update the corrupt software application.

2. Reboot your computer.

3. If you aren't able to reinstall or update the software application...

4. Reinstall the application.

If the "Kernel Panic" error is associated with random software applications, the problem probably has nothing to do with the applications themselves, but more to do with drivers or other conflicts.

Solution 3: Fix disk permissions

The problem of faulty disk permissions is yet another way that your software applications can go wrong and produce the "Kernel" error. The process of fixing permission errors is one of the most frequent troubleshooting tasks that are recommended beyond just when your iMac keeps restarting. (The diagnosis is often incorrect, but it is a safe thing to try.)

For OSX Yosemite or older:

1. Press Command + R to restart your MacBook Pro.

2. Open Disk Utility.


3. Select "First Aid," then "Repair Disk Permission."


For macOS Sierra or OSX El Capitan:

1. Open CleanMyMac X.

2. Select advanced Maintenance module.

3. Repair the disk permissions.

Fix the disk space issue:

We recommend maintaining a 20% margin for storage space, but that's just a safe estimate. Before you get started, consider which application and files you need to keep on your computer. If they are old, if they are duplicated elsewhere, or if they are remnants of previous projects, delete (or back-up and remove) the files from your MacBook Pro.

Solution 4: Launch Disk Utility

You can fix corrupted files with your Disk Utility, which allows you to perform some tasks related to your storage and hard disks.

1. Select the Apple menu.

2. Select Restart

3. Hold down Command + R as your MacBook Pro is restarting.

4. Select Disk Utility.

5. Select First Aid.

Solution 5: Disable Startup Items

When you have too many startup items set to launch at startup, your MacBook Pro's processor can be overloaded and overloaded, which can lead to a Kernel Panic error and an auto restarts. Disable startup items to see if that's the reason for your error issues.

1. Select the Apple menu.

2. Select System Preferences.

3. Select Users & Groups.

4. Select your username from the menu.

5. Select the Login Items tab

6. Select a startup item to disable and then select "–".

7. Restart your MacBook Pro.

Continue this process until all the startup items are disabled. You may be surprised by how many items are being loaded at startup. You can add back one startup at a time and reboot between each addition, so you can determine which item is causing a problem. You can use the CleanMyMac app for maintenance that may resolve your issues more quickly.

Solution 6: Reinstall a clean MacBook Pro operating system

When other fixes do not resolve the reboot issue, you need to reinstall a clean install of the operating system on your MacBook Pro.

1. Restart your Macbook Pro.

2. Hold down Command + R as your MacBook Pro is restarting.

3. Select "Reinstall macOS" or "Reinstall OS X" to initiate a clean install of the OS that came with your MacBook Pro.

Solution 7: Recover Lost Files

Recoverit Data Recovery is the best file recovery software for your MacBook Pro.

3. Be sure to verify that there are no issues with other software you've already installed in the past.

Tip 3: Verify Hardware Compatibility

Just as you can resolve software issues by being proactive about your installs, you can do the same with hardware. Some hardware just does not play nicely together, but you should also check to see if it is compatible with Mac.

1. Read through any hardware install details to find out if there are known issues with compatibility with your MacBook Pro.

3. Be sure to verify that there are no issues with other hardware that you've already installed in the past.
