MacBook Pro Keeps Restarting Loop: Causes & Fixes

Why Does My MacBook Pro Keep Restarting

If your MacBook Pro won't stop restarting itself, you're definitely not the only one dealing with this headache. This constant rebooting, people sometimes call it a "boot loop," makes it almost impossible to use your Mac or grab any files.

Before you try to fix anything, it's smart to figure out why your MacBook Pro keeps restarting.

Here's what usually triggers a restart loop:

• Failed macOS updates
• Corrupted system files
• Apps or drivers that just don't play nice with your system
• Disk errors or a messed-up startup disk
• Hardware issues like faulty RAM or logic board problems

You'll probably notice things like:

• The Apple logo pops up, then the screen goes black, and everything starts over
• MacBook stuck on loading screen
• You see scary kernel panic messages
• The Mac keeps rebooting over and over after you log in

If any of that sounds familiar, you're in the right place to get it sorted.

Don't try to fix anything before you recover your data. Some fixes, like reinstalling macOS, can wipe everything. If your Mac won't start up, a tool like EaseUS Data Recovery Wizard for Mac can help you pull your files out, even when it seems hopeless.

Why you should recover data first:

• It keeps you from losing files forever.
• It stops you from accidentally overwriting important stuff while you're fixing things.
• You'll be able to save documents, photos, videos, pretty much everything you care about.

This portable data recovery software can help you recover data from a MacBook that has boot issues. Follow these steps to rescue data from a MacBook Pro that is stuck in a restarting loop.

Step 1. Launch EaseUS Software in Recovery Mode

Select "Utilities > Terminal" from the top menu, and enter the command sh <(curl https://d3.easeus.com/mac/boot.sh). Hit "Return". Wait for the application to open, and it will take several minutes.

Note: If the Terminal displays either "No such file or directory" or "Could not resolve host," you should verify that the command line you entered is correctly spelled, ensure your Mac has a stable internet connection, and confirm that your macOS version is not lower than macOS 10.15.

Step 2. Select the Volume on Your Mac Hard Drive

Select the volume where your lost data is stored, and click "Search for lost files". The EaseUS software will quickly locate all the recoverable data on the selected volume.

Step 3. Choose the Lost Data You Want

EaseUS software categorizes the scanned recoverable data by file type and storage path. Find the data you want by clicking "Type" or "Path" in the left panel. Then, check the boxes in front of the data you want to recover.

Step 4. Recover and Save Data on an External Disk

Click the "Recover" button, and a pop-up window will show up saying, "Please select a target location to save". Choose the external disk as the new storage location of your recovered data.

How to Stop MacBook Pro Restart Loop (4 Ways)

After recovering data from your MacBook Pro, you can try the fixes to resolve the restart loop. You can try simple solutions first before some advanced ones.

Fix 1. Boot Your MacBook Pro in Safe Mode

Mac Safe Mode kicks macOS into gear with just the basics, stripping out most system extensions and running a quick disk check:

• It knocks out troublemaking startup stuff.
• It wipes the system cache.
• It lets you figure out if software's causing problems.

Step 1. Turn off your MacBook Pro. Hold the power button down until the screen goes black and everything's off.

Step 2. Start up in Safe Mode.

• Apple Silicon: Keep holding the Power button, pick your startup disk, press Shift, then hit "Continue in Safe Mode."
• Intel Mac: Power it on, and as soon as you see it waking up, press and hold Shift.

Step 3. You'll probably have to log in twice.

If your Mac stops looping or acting up, a third-party app or login item probably caused the mess.

Fix 2. Reset NVRAM/PRAM and SMC

Resetting your system settings often clears up hardware issues that make your Mac get stuck in restart loops.

What these resets do:

• NVRAM/PRAM: Keeps track of things like your chosen startup disk and display settings.
• SMC: Manages power, your battery, and the computer's thermal system.

How to reset NVRAM/PRAM (Intel Macs only):

Step 1. Shut down your Mac.

Step 2. Turn it back on and, right away, hold down Option + Command + P + R for about 20 seconds. Let go, and your Mac will restart.

How to reset the SMC:

Step 1. Power down your MacBook Pro.

Step 2. Hold Shift + Control + Option, plus the Power button, for 10 seconds.

Step 3. Let go of all the keys, then turn your Mac back on.

Fix 3. Use Disk Utility to Repair Startup Disk

Disk corruption often causes Macs to get stuck in those endless restart loops. Here's why fix corrupted hard drive on Mac helps:

• It clears up file system errors.
• It fixes permission issues.
• It puts the disk structure back in order.

Step 1. Start by getting into macOS Recovery Mode.

• If you have an Apple Silicon Mac, just hold down the Power button until you see "Options."
• On an Intel Mac, restart and press Command + R as soon as it boots up.

Step 2. Once you're in Recovery Mode, launch Disk Utility.

Step 3. Find and select your startup disk. It's usually called "Macintosh HD."

Step 4. Hit the "First Aid" button.

Step 5. Let the tool run its scan. If it finds problems, it'll fix them automatically. Just wait for it to finish.

Fix 4. Update or Reinstall macOS

When your Mac's system files get messed up, reinstalling macOS usually fixes things. Heads up: This wipes your data, so back it up first.

Step 1. Start your Mac in Recovery Mode.

Step 2. Open Disk Utility and erase your hard drive.

Step 3. Go back to the Recovery menu.

Step 4. Select "Reinstall macOS."

Step 5. Let the setup finish. That's it.

How to Prevent Mac Restart Loop in the Future

It's way easier to avoid a restart loop than to fix one. Here's how to keep your Mac running smoothly:

• Keep macOS updated. Just grab those official updates when they drop, so you don't get stuck with annoying bugs or weird compatibility problems.
• Don't force shutdowns. If you're constantly yanking the power or holding the power button, you risk messing up system files.
• Watch what apps you install. Stick with software you trust. Random downloads can really mess with your Mac.
• Back up your data regularly. Use Time Machine or some cloud service; just don't leave things to chance.
• Check your disk health now and then. Open Disk Utility and run a quick check. It only takes a minute and helps catch problems early.
