How to fix Mac that is freezing or unresponsive and requires troubleshooting steps

Summary

This guide helps you troubleshoot and resolve: How to fix Mac that is freezing or unresponsive and requires troubleshooting steps. Follow the steps below to fix the issue.

Common Causes

When your Mac becomes unresponsive, freezes mid-task, or shows the spinning beach ball cursor for extended periods, it usually indicates that a process or the entire system has run out of resources or encountered an error. This guide walks you through diagnosing the cause and resolving the issue, starting with the least invasive fixes and progressing to more thorough solutions. Most freezes can be resolved without losing data, but if your Mac is completely locked up, you may need to force restart it first.

Quick Fix Steps

If your Mac is currently frozen, try these steps in order before moving to the detailed instructions below.

1. Wait 30 to 60 seconds — some operations genuinely take time, especially on older Macs.
2. Click anywhere on the screen or press a key to check whether the system is responsive.
3. Force quit the unresponsive application using Command + Option + Escape.
4. Open Activity Monitor from Applications > Utilities and check CPU and memory usage.
5. Save your work in other open apps and restart your Mac from the Apple menu.
6. If the Mac will not shut down normally, hold the Power button for 10 seconds to force a restart.

Diagnose the Problem

Before applying fixes, it helps to identify whether the freeze is system-wide or limited to a single application.

Is It One App or the Whole System?

• If only one application is frozen, you can usually move other windows and use the Apple menu. This points to an app-specific issue.
• If the entire system is unresponsive — the cursor is a spinning beach ball, the Apple menu does not drop down, and keyboard input has no effect — the issue is system-wide.
• If the issue occurs every time you open a specific app or document, that app or file is likely the cause.

Check Activity Monitor

Activity Monitor shows you exactly what is consuming your Mac's resources.

1. Open Finder and select Go > Utilities from the menu bar.
2. Double-click Activity Monitor.
3. Click the CPU tab and look for any process using a high percentage of CPU consistently.
4. Click the Memory tab and check the Memory Pressure graph at the bottom. If it is red, your Mac is running out of RAM.
5. Click the Energy tab to see which apps are drawing the most power, which can cause freezes on laptops.
6. Select a suspicious process and click the X button in the toolbar, then choose Force Quit.

Force Quit an Unresponsive Application

When a single app stops responding, force quitting it is the fastest solution and will not affect other open applications or documents.

1. Press Command + Option + Escape to open the Force Quit Applications window.
2. Select the frozen application from the list.
3. Click Force Quit.
4. Reopen the application and check whether the issue recurs.

Alternatively, you can right-click (or Control-click) the app's icon in the Dock and hold Option to reveal the Force Quit option.

Restart or Shut Down Your Mac

A restart clears temporary files, resets running processes, and resolves most transient freezes.

Normal Restart

1. Click the Apple menu in the top-left corner.
2. Select Restart...
3. Confirm by clicking Restart in the dialog box.

Force Restart (When the System Is Completely Frozen)

1. Press and hold the Power button for approximately 10 seconds until the Mac turns off completely.
2. Wait a few seconds, then press the Power button again to start the Mac.
3. Log in as usual and check whether the issue is resolved.

Check for macOS Updates

Apple regularly releases updates that fix bugs causing freezes and stability issues. Running an outdated version of macOS is a common cause of recurring problems.

1. Click the Apple menu and select System Settings (or System Preferences on older macOS versions).
2. Click General, then Software Update.
3. If an update is available, click Update Now or Upgrade Now.
4. Allow the update to download and install, then restart when prompted.

Free Up Disk Space

macOS needs free disk space to operate efficiently, particularly for swap memory when RAM is full. A nearly full startup disk can cause severe slowdowns and freezes.

1. Click the Apple menu and select System Settings > General > Storage.
2. Review the recommendations and click Review next to each category.
3. Empty the Trash after deleting files.
4. Aim to keep at least 10 to 15 percent of your startup disk free.

Manage Login Items and Startup Apps

Too many applications launching at login can overwhelm your Mac, especially on startup. Disabling unnecessary login items often resolves freezes that occur shortly after booting.

1. Open System Settings > General > Login Items.
2. Review the list under Open at Login.
3. Select any apps you do not need immediately and click the − button to remove them.
4. Restart your Mac and observe whether performance improves.

Test in Safe Mode

Safe Mode starts macOS with only essential system processes and disables third-party startup items and login items. If your Mac runs smoothly in Safe Mode, a third-party application or extension is likely the cause.

Enter Safe Mode on Apple Silicon Macs

1. Shut down your Mac completely.
2. Press and hold the Power button until you see Loading startup options.
3. Select your startup disk, hold Shift, then click Continue in Safe Mode.
4. Log in — you may need to log in twice.

Enter Safe Mode on Intel Macs

1. Shut down or restart your Mac.
2. Immediately press and hold the Shift key as your Mac starts up.
3. Release the key when you see the login window, then log in.

Test your Mac in Safe Mode for several minutes. If the freezes do not occur, restart normally and begin removing recently installed applications or extensions one at a time to identify the culprit.

Reset NVRAM or PRAM

NVRAM (on Apple Silicon and modern Intel Macs) and PRAM store certain settings including display resolution, startup disk selection, and recent kernel panic information. Resetting it can resolve some freeze-related issues.

1. Shut down your Mac.
2. Press the Power button, then immediately press and hold Option + Command + P + R.
3. Hold the keys for about 20 seconds. On Apple Silicon Macs, release when you see the Apple logo appear and disappear twice. On Intel Macs, release when you hear the startup chime a second time.
4. Release the keys and allow your Mac to start up normally.

Reinstall macOS

If none of the above steps resolve the issue, reinstalling macOS may be necessary. Reinstalling does not erase your personal files but replaces the system files.

1. Back up your Mac using Time Machine or another backup method.
2. Restart your Mac and hold Command + R (Intel) or the Power button (Apple Silicon) to enter Recovery Mode.
3. Select Reinstall macOS from the macOS Utilities window.
4. Follow the on-screen prompts to complete the installation.
