Sometimes your Mac freezes, and one app just won’t respond. Don’t panic—there’s a simple fix. Learn how to force quit Mac apps safely and quickly with these proven methods.
What Does ‘Force Quit Mac’ Mean?
-(1).jpg?w=1200)
When an application on your Mac stops responding, clicking around won’t help. This is where the ‘force quit mac’ function becomes essential. It allows you to manually close unresponsive programs that are hogging system resources or freezing your workflow. Unlike a normal quit, force quitting interrupts the app immediately, even if it’s stuck in a loop or crashed.
Why Apps Freeze on macOS
Apps can freeze for various reasons, including insufficient memory, software bugs, or conflicts with other running processes. For example, a browser with too many tabs open might consume excessive RAM, causing it to hang. Similarly, outdated software or incompatible plugins can trigger crashes. Understanding these causes helps prevent future issues and makes the ‘force quit mac’ process a temporary but necessary solution.
- High CPU or memory usage
- Software bugs or glitches
- Incompatible third-party plugins
Is Force Quitting Harmful?
Occasional force quitting is safe and won’t damage your Mac. However, doing it frequently may lead to data loss in unsaved documents or corrupt app preferences. Apple designs macOS to handle abrupt closures gracefully, but it’s always best to save your work regularly. If you find yourself force quitting the same app repeatedly, consider reinstalling it or checking for updates.

How to Force Quit Mac Using Keyboard Shortcut
One of the fastest ways to force quit mac apps is using a simple keyboard shortcut. This method works across all modern macOS versions and requires no mouse interaction, making it ideal when your system is partially frozen.
Step-by-Step: Command+Option+Escape
To use this method, press Command (⌘) + Option (⌥) + Escape simultaneously. A small window titled ‘Force Quit Applications’ will appear, listing all currently running apps. Select the unresponsive one and click ‘Force Quit’. Confirm if prompted. The app should close within seconds.
- Works even if the mouse is unresponsive
- Available in all macOS versions
- Instant access without navigating menus
Tips for Using the Shortcut Effectively
If the app doesn’t close immediately, wait 10–15 seconds before trying again. Repeatedly pressing the shortcut won’t speed up the process and might confuse the system. Also, ensure you’re selecting the correct app—closing the wrong one could disrupt your workflow. If the entire system is frozen, this shortcut may not work, and you’ll need to try alternative methods.
Force Quit Mac via Apple Menu
If you prefer using menus over shortcuts, the Apple logo in the top-left corner offers a reliable way to force quit mac applications. This method is especially useful for beginners who aren’t comfortable with keyboard commands.
Navigating the Apple Menu
Click the Apple () icon in the top-left of your screen. From the dropdown menu, select ‘Force Quit…’. This opens the same dialog box as the keyboard shortcut, showing all active apps. Choose the frozen application and click ‘Force Quit’. This method is slightly slower but more intuitive for new users.
- Easy to remember and access
- No need to memorize key combinations
- Great for users with accessibility needs
When the Apple Menu Is Unresponsive
If the Apple menu doesn’t respond, it likely means the entire GUI is frozen. In such cases, neither the shortcut nor the menu will work. You’ll need to resort to a hard reboot by holding the power button. However, this should be a last resort, as it can lead to system file corruption if done too often.

Using Activity Monitor to Force Quit Mac Processes
Activity Monitor is macOS’s built-in task manager, offering granular control over system processes. It’s the most powerful tool for force quitting mac apps, especially when dealing with background processes or hidden services that don’t appear in the standard Force Quit window.
Opening and Navigating Activity Monitor
You can open Activity Monitor by searching for it in Spotlight (Command + Space, then type ‘Activity Monitor’). Once open, you’ll see tabs for CPU, Memory, Energy, Disk, and Network. Switch to the ‘CPU’ tab to identify which processes are using the most resources. Look for apps with high ‘% CPU’ usage or status labeled ‘Not Responding’.
- Spotlight search: Fastest way to launch
- CPU tab: Best for detecting frozen apps
- Memory tab: Useful for spotting memory leaks
How to Terminate a Process
Select the problematic process, then click the ‘X’ button in the top-left corner of the window. A confirmation dialog will appear—click ‘Force Quit’. Unlike the standard method, Activity Monitor lets you kill system-level processes, though caution is advised. Terminating critical system processes can cause instability or require a restart.
Advanced Tips for Power Users
You can sort processes by CPU, memory, or energy impact to quickly identify resource hogs. Right-click (or Control-click) on a process to view its hierarchy or sample its behavior. This is useful for diagnosing recurring freezes. Additionally, Activity Monitor can help you spot malware—unknown processes consuming high CPU should be investigated.
Terminal Commands to Force Quit Mac Apps
For advanced users, the Terminal offers precise control over app termination. Using command-line tools like kill and killall, you can force quit mac applications with specific parameters, making it ideal for automation or scripting.
Using the ‘kill’ Command
First, find the Process ID (PID) of the app. Open Terminal and type ps aux | grep [app-name], replacing [app-name] with the app you’re targeting (e.g., ‘Safari’). Note the PID number. Then, type kill [PID] to send a termination signal. If the app doesn’t respond, use kill -9 [PID] to force it.
kill: Sends a polite termination signal (SIGTERM)kill -9: Forces immediate termination (SIGKILL)ps aux: Lists all running processes
Using ‘killall’ for Simplicity
The killall command is easier for beginners. Simply type killall [app-name], like killall Safari. This kills all instances of the app by name. It’s faster than finding the PID but less precise if multiple apps have similar names.
Example:
killall Google Chromewill close all Chrome windows instantly.
What to Do After Force Quitting an App
Force quitting is just the first step. To maintain system stability and prevent future crashes, follow up with a few essential actions.
Restart the App and Check for Updates
After force quitting, relaunch the app. If it crashes again immediately, there may be a deeper issue. Check for software updates via the App Store or the app’s built-in updater. Developers often release patches for known bugs that cause freezing.
- Go to App Store > Updates
- Check the app’s ‘About’ section for updates
- Visit the developer’s website for beta versions
Clear App Cache and Preferences
Corrupted preference files or bloated caches can cause repeated crashes. Navigate to ~/Library/Preferences/ and delete the app’s .plist file (e.g., com.apple.Safari.plist). Also, clear cache in ~/Library/Caches/. Be cautious—deleting the wrong file can reset app settings.

Monitor System Health
Use Activity Monitor regularly to track CPU and memory usage. If your Mac consistently runs out of memory, consider upgrading RAM or closing background apps. Tools like ForkLift or iStat Menus offer enhanced system monitoring.
Preventing the Need to Force Quit Mac Apps
While knowing how to force quit mac is crucial, preventing freezes is even better. Proactive maintenance keeps your system running smoothly and reduces reliance on emergency measures.
Keep macOS and Apps Updated
Apple regularly releases security patches and performance improvements. Enable automatic updates in System Settings > General > Software Update. Similarly, keep third-party apps updated to avoid compatibility issues.
- Enable automatic macOS updates
- Use app updaters like Setapp or MacUpdate
- Remove unused or outdated software
Manage Startup Items
Too many apps launching at startup can slow down your Mac and increase the chance of conflicts. Go to System Settings > General > Login Items to disable unnecessary programs. This reduces boot time and frees up memory.
Use Safe Mode for Diagnostics
If your Mac frequently freezes, boot into Safe Mode by holding Shift during startup. This disables non-essential extensions and clears system caches. If the problem disappears in Safe Mode, a third-party extension is likely the culprit.
Apple recommends using Safe Mode for troubleshooting: Learn more on Apple’s guide.
When Force Quitting Isn’t Enough: System-Level Solutions
Sometimes, no matter how many times you force quit mac apps, the problem persists. This indicates deeper system issues that require more advanced intervention.
Reset NVRAM/PRAM
NVRAM (Non-Volatile Random-Access Memory) stores settings like volume, display resolution, and startup disk. Corruption here can cause instability. Reset it by shutting down, then turning on your Mac and immediately pressing Option + Command + P + R for about 20 seconds.
- Fixes audio, display, and boot issues
- Safe to perform regularly
- May reset some system preferences
Run First Aid in Disk Utility
File system errors can cause apps to freeze. Open Disk Utility (via Recovery Mode if needed), select your startup disk, and click ‘First Aid’. This scans and repairs disk permissions and directory issues.
Reinstall macOS as a Last Resort
If all else fails, reinstalling macOS can resolve deep-seated software problems. Boot into Recovery Mode (Command + R), select ‘Reinstall macOS’, and follow the prompts. Your files remain intact, but it’s wise to back up first using Time Machine.
