Mac Is Frozen: What to Do

Although Macs are reliable computers, they aren’t immune from screen hanging or slow processing. That includes freeze-ups, where the system becomes unresponsive, and you’re unable to do anything with your computers. In rare cases, your laptop screen can freeze completely, and you won’t even be able to move your mouse cursor.


More commonly, your mouse cursor might still be moving, but instead of an arrow, you see a spinning ball. None of these situations are great, but what can you do if it happens to you? How can you unfreeze your Mac and get back to what you were doing? In this guide, we’ll look at a few potential solutions to help you fix a frozen Mac.


Before we start:


Viruses and other malware can cause your Mac to constantly freeze. That’s why we recommend running a regular virus detection scanner to notice if your laptop is slowing down. Use MacKeeper’s Anti Virus to check if malware or viruses are the reason why your MacBook freezes.

  1. Download MacKeeper and install it onto your MacBook.
  2. Launch the app and access the Antivirus feature.
  3. Click Start Scan.
  4. If any malware is found, select it from the list, and click Move to quarantine.

Why does your Mac keep freezing

Experiencing a frozen Mac can disrupt your productivity and be incredibly frustrating, especially when you're in the middle of crucial tasks. When your laptop is constantly freezing, identifying the root cause becomes essential.


Here are some potential culprits for why your Mac keeps freezing:

  • Software conflicts or outdated applications
  • Insufficient RAM or storage space
  • Failing or faulty hardware
  • Not updating OS X or computer software regularly

How to unfreeze your Mac

Dealing with a frozen Mac can vary from a quick fix to navigating potential hardware issues. Whether it's a particular app that’s lagging or all-around slowness during tasks, the freezing might be trying to alert you to a deeper problem. Therefore, learning how to stop Mac from freezing is crucial.


Here are some of the most common things you can try to solve your Mac’s freezing:  

Force quit apps

Being able to quickly quit apps that don't respond can help you get back control of your frozen Mac. macOS includes a simple tool you can use to force quit apps that are lagging or slowing down your activities. To force quit on a Mac when it’s frozen, you can use a keyboard shortcut when your laptop is otherwise unresponsive.


Here’s how to use the force quit tool on a Mac:

  1. If you’re able to, save any work you’ve opened.
  2. Press Command + Option + Esc keys to open up the Force Quit Applications tool.
  3. Choose what you want to quit out of, and click the Force Quit button.
  4. In the pop-up, click Force Quit.
 To force quit out of an app to fix a frozen Mac, begin by pressing down on the Command + Option + Esc keys. The action will bring up the Force Quit Application tool.
Step 1. Press Command + Option + Esc to open the Force Quit Application tool
After pressing the relevant keys on your keypad, you can now select the app you want to Force Quit from the pop-up menu. This should help unfreeze your Mac if an app is lagging or making your laptop unresponsive.
Step 2. Press Force Quit on what you want to quit out of

Restart your Mac

In many cases, the easiest solution to speed up your device is to restart the Mac. Although, the success of this action depends on how frozen your Mac display is. If you can’t access any menus or even move your mouse cursor, then you can’t restart your Mac. But if it’s just one or two apps that have frozen, and your laptop still responds to commands, you might still be able to restart.


You can reboot your Mac as you normally would, like this:

  1. Click the Apple icon in the top left of your screen.
  2. Click Restart.
  3. Make sure Reopen windows when logging back in is unticked.
  4. Click Restart.
To restart your Mac, to resolve lagging or hanging applications, you will need to click on the Apple icon and choose Restart.
Step 1. Click the Apple icon and choose Restart
Once you have selected Restart, make sure to untick Reopen windows. This action will ensure unresponsive apps are quit and restarted to help fix frozen display issues or laptop slowness.
Step 2. Untick Reopen Windows when logging back in

If your device keeps shutting down randomly, this might be an indication of deeper issues relating to outdated software, malware threats, or device malfunctions.

Power down your Mac

It’s generally not a good idea to try shutting down your Mac forcefully. However, if you’re trying to fix a frozen Mac that isn’t responding at all, then you may have no choice.


To force your Mac to power down is simple:

  1. Press and hold the Power button, or Touch I.D button on MacBook Air M1 & M2.
  2. Wait until your Mac shuts down.
  3. Give it a few seconds before turning your Mac back on.

Note from our experts: 


We only suggest manually powering down your Mac if your apps and menus aren’t responding or your mouse cursor is completely stuck. Still, see that your Mac won’t turn on? In this case, you may need to boot it into safe mode first to proceed.  

Stop demanding background processes

Macs, whether powered by Intel or Apple Silicon chips, have finite processing capabilities. Overloading these processors with numerous demanding apps or poorly coded software can unexpectedly freeze your Mac. If background apps monopolize processing power, we suggest using Activity Monitor. It can assist in addressing energy-consuming processes causing lagging, ensuring smoother performance.


This is how you can close background processes on your Mac:

  1. Go to Applications > Utilities, and start Activity Monitor.
  2. Look for apps using a high CPU percentage. If you see anything, double-click it.
  3. Click the Quit button.
  4. Click Quit. If it doesn’t work, repeat these steps but choose Force Quit.
The Utilities window, opened from Mac’s Applications, shows Activity Monitor found and selected as the tool to help you close background processes
Step 1. Go to Applications > Activity Monitor
The Activity Monitor window displays the list of all processes happening on your Apple device, with the CPU column indicating their energy consumption in percent
Step 2. Open the CPU tab in Activity Monitor
While the most consuming app is chosen by a double-click, you can confirm to stop it with the Quit button
Step 3. Quit the process
Step 4. Confirm the process removal

Remove recently installed apps

If you’re constantly dealing with Mac keep freezing, it may be because of a badly made app. If that’s the case, the easiest thing would be to remove the offending app. The most likely offenders will be the apps you were installing most recently. Therefore, those are the ones you should uninstall. If you can’t get into macOS normally because your Mac freezes at startup, you may need to boot into safe mode first.


Here’s how to find and remove recently installed Mac apps:

  1. Open the Applications folder on your Mac, and click the button to view the items as a list.
  2. Now right-click anywhere in the bar running along the top, where it has the Name, Size, and so on. Select Date Added.
  3. This adds a new Date Added column. Click it to sort the items by the date they were added to your Mac.
  4. Right-click apps you don’t want to leave on your Mac, and select Move to Trash (or Move to Bin).
To bring some sorting out among your apps on Mac, deleting the unnecessary software and leaving only the actively used ones, go to the Applications folder
Step 1. Open the Application folder
In the Applications folder, right-click anywhere to open the new window. Here, find and select the Date Added option
Step 2. Add the sorting filter by Date
In the Applications folder, right-click anywhere to open the new window. Here, find and select the Date Added option
Step 3. Sort the apps by Date Added
At the top of the Date Added column, in the Apps folder, you’ll see the most recently downloaded apps. Choose the one you don’t need, right-click on it, and Move to Trash
Step 4. Remove the app by moving it to Bin (Trash)

Check your disk health

Unfortunately, laptop hardware doesn’t last forever. If your Mac keeps freezing, it could simply be because your hard disk or SSD is failing. It could also be caused by a less catastrophic form of data corruption, which can be fixed more easily. In either case, the macOS Disk Utility is a good place to start.


Here’s how to check your Mac’s disk health:

  1. Open Finder, go to Applications > Utilities, and start Disk Utility.
  2. Click the First Aid button.
  3. Click Run and follow by Continue.
  4. Wait while Disk Utility scans your disk. If it finds any problems, it’ll let you know.
If you’re eager to inspect your Macbook’s disc health, do it easily with the Disc Utility, found among Utilities
Step 1. Go to Applications > Utilities > Disk Utility
In the Disc Utility functionality opened, you’ll find the First Aid button, located at the right top of the screen. Click on it
Step 2. Click on First Aid
The Disc Utility app will ask you whether you’d to run the First Aid on the chosen program. React with the Run button
Step 3. Run the First Aid
Finally, you’ll be shown the warning message that the computer will stop responding for a while. Worry not and click Continue
Step 4. Confirm the start of the First Aid

Run a virus scan

Viruses and malware can slow down your device and lead to constant MacBook freezes. That’s why it’s a good idea to run a virus scan to prevent your Mac from freezing. If you’re unable to get into macOS normally due to your desktop or trackpad not responding, then try running your antivirus software in safe mode.


Here’s how to run an antivirus scan using MacKeeper:

  1. Start MacKeeper, and select Antivirus from the side menu.
  2. Click Start Scan.
  3. Wait for the scan to complete.
  4. Select anything MacKeeper finds, and click Move to quarantine.
  5. Restart your Mac.
In the MacKeeper app, our Antivirus tool can be selected from the side menu. It can be used as a possible method to remedy a slow or lagging Mac that keeps freezing.
Step 1. Open Antivirus in MacKeeper
In MacKeeeper’s Antivirus window, you'll see an option to get your laptop checked for viruses and malware. For this, you just need to click on Start Scan.
Step 2. Start the Antivirus scan
MacKeeeper’s Antivirus window shows the progress of scanning on Mac. Wait until the app finishes its scan
Step 3. Wait until the end of the scan
If the virus is a living matter on your computer, now it’s time to end its life. Click on Move to Quarantine to clear up your system
Step 4. Check the scan results

Reset your Mac’s NVRAM

The NVRAM of your Mac refers to its non-volatile random access memory. Sometimes, you can fix MacBook freezes and lagging by resetting the NVRAM. However, our experts should warn you that it works differently with newer Mac models that don't use Apple’s M1 chip. Therefore, resetting your NVRAM is only a suitable option for Intel Macs with a different chip, like the M2.


Here’s how to reset your Mac’s NVRAM:

  1. Restart your Mac.
  2. Press and hold Cmd + Opt + P + R keys at the same time, until the grey screen appears.
  3. Hold down these keys until your Mac restarts, and you hear the startup chime for the second time.
  4. Release all the keys.
To reset your Mac’s NVRAM, to help fix Mac freezing or lagging issues, you'll need to start by restarting your device. To do this, click on the Apple icon and select Restart.
Step 1. Restart your Mac
Once you have selected Restar, press and hold down all four keys on your keyboard until a grey screen appears. Hold them down until your Mac chime sounds indicating your laptop is back on.
Step 2.  Press Command + Option + R + P Keys at the same time

Reset your Mac’s SMC

Similar to NVRAM, you can potentially fix an Apple computer frozen by simply resetting the SMC (System Management Controller). Again, M1 Macs don’t have this feature, so this only applies to Intel Macs that are slowing down, causing apps to not respond or lag.


Resetting your Mac’s SMC is simple:

  1. Begin by Shutting down your Mac.
  2. Disconnect everything other than the power.
  3. Press the left side Shift + Ctrl + Opt keys and power button at the same time. Hold all four keys for 10 seconds.
  4. Release all the keys and the power button at the same time.
  5. Turn your Mac back on.
To reset your Mac’s SMC, you'll first need to power down your Mac. You can do this by clicking the Apple icon and selecting Shut Down from the menu.
Step 1. Shut down your Mac
Step 2. Press Shift + Ctrl + Opt keys and the power button for 10 seconds

Boot Mac in safe mode

Another solution to resolving Mac keep freezing issues is to boot your Mac in safe mode. This is known to frequently work to troubleshoot issues by isolating potential software conflicts. Safe mode allows you to identify and address software-related concerns, but it’s only suitable for Intel-based and Apple Silicon Macs.

Intel-based Mac:

  1. Here’s how to boot an Intel Mac into safe mode:
  2. Power off your Mac completely.
  3. Turn your Mac back on and immediately press and hold Shift.
  4. Release the Shift key only when you see the Apple logo and progress bar. Safe mode will display Safe Boot on the login window.
To boot your Mac into safe mode to help fix lagging or freezing issues, you'll first need to power off your device by clicking on the Apple icon and selecting Shut Down.
Step 1. Power off Mac
Now you can turn back on your Mac device, but make sure you press and hold down the Shift key right away, to enter your Mac into safe mode.
Step 2. Turn your Mac back on and hold down Shift
Only release the shift key when the Apple logo and process bar appear. When your device is ready to log back into, you should see Safe Boot on the login window.
Step 3. Release Shift when the Apple log and progress bar appear

Mac with Apple Silicon:

Here’s how to boot Macs with Apple Silicon into safe mode:

  1. Power off your Mac completely.
  2. Turn on your Mac and immediately press and hold the Power button.
  3. Release the Power button when you see the startup options. Select Options and then click Continue.
  4. Choose your startup disk, then hold down the Shift key and click Continue in Safe Mode.
To enter safe mode on a Mac with Apple silicon, begin by powering off your device by clicking on the Apple icon and selecting shut Down.
Step 1. Power off your Mac

Step 2. Hold the Power button down until you see the startup options
Now, whilst holding down the shift key, you will be able to choose your startup disk and click continue to enter safe mode on your Apple Mac device. Now you can you identify and address software-related concerns that could be slowing down your Mac.
Step 3. Choose your startup disk, hold the Shift key and click Continue

Run Apple Diagnostics

For users plagued with constant MacBook freezes, or issues with apps that don’t respond, your laptop may need an in-depth check. That’s why you should always identify the cause of any lagging with the help of Apple Diagnostics.  


Here’s how to run Apple Diagnostics to assess potential hardware concerns and fix a frozen Mac:

  1. Shut down your Mac completely.
  2. Turn on your Mac and immediately press and hold the D key.
  3. Select your preferred language and click Next.
  4. Apple Diagnostics will automatically begin running to detect any hardware issues.

To be able to run diagnostics on your Apple device, you'll need to first Shut Down your Mac.
Step 1. Shut Down your Mac
Once you've turned off your Mac, it can then be switched back on, but be sure to hold the D key to be able to open diagnostics to help find out if your Mac leggings or slowness is due to hardware issues.
Step 2. Turn Mac back on and hold the D key
Now you need to allow your Mac to run a full diagnostics assessment of your drive to find out if any hardware issues are contributing to the slowness of your Mac.
Step 3. Let your Mac check for any hardware issues
