Why Macs Sometimes Freeze or Crash

Although Macs are generally very stable, freezes can still happen for several reasons.

Software Bugs

Some apps may contain bugs or conflicts that cause macOS to hang. This is especially common with outdated apps that haven’t been updated for the latest macOS version.

Tip: If your Mac frequently freezes when using a specific app, check whether the app has an update available. Many freezing issues are caused by apps that haven’t been updated for the latest version of macOS (currently Tahoe).

Too Many System Resources Being Used

If your Mac runs too many apps, browser tabs, or background processes at once, it can run out of available memory or CPU power, causing the system to freeze.

Hardware Issues

Problems such as overheating, faulty RAM, or failing storage drives can occasionally cause a Mac to crash or freeze unexpectedly.

Corrupted System Files

Sometimes macOS system files, preferences, or caches become corrupted, which can cause apps or the entire system to lock up.

Peripheral Devices

External devices like USB hubs, printers, or external drives can sometimes cause freezes if they have faulty drivers or firmware.

Understanding these causes can make it easier to prevent your Mac from freezing in the future.

When Macs Most Commonly Freeze

From our testing and reader feedback, Macs usually freeze in a few common situations:

• When too many browser tabs are open
• When an app stops responding or crashes
• After waking from sleep
• When external devices or USB hubs cause driver conflicts
• When macOS hasn’t been restarted for a long time

If your Mac freezes in one of these situations, the troubleshooting steps below should resolve the issue.

Tested on Intel and Apple Silicon Macs

The fixes in this guide were tested on multiple Macs running recent versions of macOS, including:

• MacBook Air (M1-M5)
• MacBook Pro (Intel and Apple Silicon)
• iMac
• Mac mini

If your Mac or MacBook is frozen, not responding, or stuck with the spinning beach ball, the steps below will help you quickly get it working again.

1. Force Quit Unresponsive Apps

If only one application is frozen, you may be able to fix the problem without restarting your Mac simply by Force Quitting an application (the same as Ctrl-Alt-Delete on a PC).

Keyboard Shortcut

Press: Option + Command + Escape

This opens the Force Quit Applications window.

1. Click on the frozen application
2. Click Force Quit

Dock Method

You can also force quit an app directly from the Dock.

1. Right-click (or Control-click) the app icon
2. Hold the Option key
3. Click Force Quit

2. Use Activity Monitor

If your Mac is running extremely slow but hasn’t completely frozen, Activity Monitor (similar to Task Manager on a PC) can help identify the problem.

1. Open Applications > Utilities > Activity Monitor
2. Click the CPU tab
3. Look for apps using large amounts of CPU or memory, often highlighted in red if they have frozen or crashed.
4. Select the process
5. Click the X button to force quit it

This often fixes freezing caused by runaway processes or memory leaks.

If you find the application is causing persistent problems with your Mac, then you may also want to uninstall it.

3. Restart Your Mac

If the entire system is frozen, restarting may be necessary.

Normal Restart

Click the Apple logo > Restart

Force Restart

If the Mac is completely unresponsive:

1. Press and hold the power button for about seven seconds or keep holding until the Mac switches off
2. Wait a few seconds
3. Press the power button again to restart

Note: This should only be used when necessary because unsaved data may be lost.

4. Disconnect External Devices

External hardware can sometimes cause macOS to freeze.

1. Shut down your Mac
2. Disconnect all external devices such as:
   • USB drives
   • printers
   • hubs
   • external monitors
3. Restart your Mac

If the Mac works normally afterwards, reconnect devices one at a time to find the culprit.

5. Reset NVRAM / PRAM (Intel Macs)

NVRAM stores system settings like speaker volume, display resolution, and startup disk information.

1. Shut down your Mac
2. Turn it on and immediately press:

Command + Option + P + R

3. Hold the keys for about 20 seconds
4. Release them when the Mac restarts.

Apple Silicon Macs automatically reset NVRAM when needed, so this step mainly applies to Intel Macs.

6. Boot Your Mac in Safe Mode

Safe Mode starts macOS with only essential components and performs system checks.

To start Safe Mode

1. Shut down your Mac
2. Turn it on while holding the Shift key
3. Release the key when the login window appears

Safe Mode can help identify problematic apps or login items.

7. Free Up System Resources

Your Mac may freeze if it runs out of available memory or CPU power.

Try:

• Closing unused applications
• Reducing the number of browser tabs
• Removing unnecessary login items
• Restarting occasionally to clear memory

You can also check system usage using Activity Monitor.

8. Update macOS

macOS updates often include fixes for system bugs that can cause freezing. Updating to the latest version of macOS can fix this instantly.

How to check for updates:

1. Click the Apple menu
2. Open System Settings
3. Select General > Software Update

Installing updates can resolve many stability issues. For more help, check our guide on how to update a Mac.

9. Run Disk Utility First Aid

Disk errors can cause apps or the entire system to freeze.

1. Open Applications > Utilities > Disk Utility
2. Select your startup disk
3. Click First Aid
4. Run the scan and repair process

10. Reset the System Management Controller (Intel Macs)

The System Management Controller (SMC) controls hardware features like power management, fans, and battery behavior.

Resetting the SMC can fix freezes related to hardware functions.

The reset process varies depending on your Mac model, so it’s best to follow Apple’s official instructions for your device.

Apple Silicon Macs automatically manage these functions and do not require manual SMC resets.

11. Mac Frozen but Mouse Still Moves

Sometimes your Mac appears frozen but the mouse cursor still moves. This usually means a specific app has stopped responding rather than the entire system.

Try the following:

1. Press Command + Option + Escape to open the Force Quit window.
2. Select the app that says “Not Responding.”
3. Click Force Quit.

If the app doesn’t appear in the list:

1. Open Activity Monitor
2. Find the app using the most CPU
3. Select it and click Force Quit

Once the app closes, your Mac should return to normal.

12. Mac Frozen With Spinning Beach Ball

If you see the spinning rainbow wheel (often called the “beach ball of death”), it means macOS is waiting for an app to respond.

This usually happens when:

• An app is overloaded
• Your Mac runs out of memory
• A process is stuck

How to fix it

1. Wait about 30 seconds in case the app recovers.
2. Press Command + Option + Escape.
3. Force quit the app showing Not Responding.

If the beach ball appears frequently, try:

• closing unused browser tabs
• restarting your Mac
• checking Activity Monitor for heavy CPU usage.

When a Frozen Mac Might Indicate a Hardware Problem

If your Mac freezes frequently even after trying all the steps above, it may indicate:

• failing SSD
• overheating
• faulty RAM
• internal hardware damage

In these cases, it’s best to contact Apple Support or visiting your nearest authorized service provider is recommended for further assistance.

How to Prevent Your Mac Freezing Again

While occasional freezes can happen on any computer, there are several things you can do to reduce the chances of your Mac freezing in the future.

Keep macOS Updated

Apple regularly releases updates that fix bugs and performance issues.
Go to Apple menu > System Settings > General > Software Update to install the latest updates.

Limit Login Items

Too many apps starting when your Mac boots can slow it down.

Go to:
System Settings > General > Login Items

Remove apps you don’t need starting automatically by using the “-” symbol at the bottom of the list.

Avoid Running Too Many Apps

Opening too many browser tabs or heavy applications at once can consume system resources and cause your Mac to freeze.

Restart Your Mac Occasionally

Unlike iPhones or iPads, Macs benefit from occasional restarts to clear memory and background processes.

Keep Enough Free Storage

macOS needs free storage space to run efficiently. Try to keep at least 10–20% of your disk space free. For help, check our guide on how to check storage on a Mac.
