You’re right in the middle of something. Maybe you’re rendering a 4K video in Final Cut Pro, or perhaps you just have eighty-seven Chrome tabs open because you’re researching a vacation you can't actually afford yet. Suddenly, the spinning beach ball of death appears. It just sits there, mocking you. Your cursor moves, but the app is ghosting you. It’s frozen.
Knowing how to force quit a program on Mac is basically a survival skill at this point. macOS is generally stable, but software is written by humans, and humans make mistakes. Memory leaks happen. Code loops. Processes hang. When an app stops responding, you don't need to hard-reboot your entire machine and risk losing unsaved data in other apps. You just need to kill the one offender.

Honestly, most people only know one way to do this. They usually go for the Apple menu. But what if the Apple menu is frozen too? What if your mouse isn't tracking? There are actually about five different ways to handle a stubborn app, ranging from the "gentle nudge" to the "nuclear option" involving the Terminal.
The Command-Option-Escape Shortcut (The Gold Standard)
This is the one you should memorize. It’s the Mac equivalent of Ctrl+Alt+Delete, but it’s arguably more efficient because it brings up a dedicated "Force Quit Applications" window immediately.
Press Command + Option + Escape all at once.
A small window pops up listing every active application. If an app is truly struggling, macOS will usually helpfully highlight it with a red "Not Responding" label next to the name. You just click the name of the app and hit the blue Force Quit button. A second confirmation box will appear—standard Apple safety stuff—asking if you’re sure. Click it again.
Boom. The app vanishes.
I’ve seen people panic when this window doesn't appear instantly. If your RAM is completely maxed out, it might take five or ten seconds for the system to register the interrupt command. Wait for it. Don't just mash the keys repeatedly like you're playing a fighting game. Give the OS a second to breathe and prioritize the request.
Using the Dock When the App is Just Being "Difficult"
Sometimes an app hasn't completely crashed the system, but it's just spinning. Maybe it's stuck on a save dialogue or a weird network request. In these cases, you might still be able to use your mouse.
Find the icon of the unresponsive app in your Dock. If you right-click it (or Control-click), you'll see the standard menu with "Quit" at the bottom. But "Quit" sends a polite request to the app. The app is currently ignoring polite requests.

Hold down the Option key while that menu is open.
You’ll see "Quit" magically transform into "Force Quit." Select that. This bypasses the app's internal "Do you want to save?" checks and just cuts the power. It's fast. It's effective. It works about 90% of the time.
The Apple Menu Method
If you’re a mouse-heavy user and shortcuts feel like a chore, just click the Apple logo in the top-left corner of your screen. About halfway down the dropdown menu, you’ll see Force Quit... clicking this opens the exact same window we talked about earlier.
It's a solid backup, but it's the first thing to break if the Finder or the WindowServer process is the thing that's actually crashing. If your top menu bar is missing or won't click, move on to the more aggressive methods.
Activity Monitor: The Nuclear Option for Techies
Most Mac users treat Activity Monitor like a scary "under the hood" engine component they shouldn't touch. That’s a mistake. It is the most powerful tool you have for managing a system that feels sluggish.
- Open Spotlight (Command + Space).
- Type "Activity Monitor" and hit Enter.
- Look at the % CPU column.
If an app is freezing your Mac, it’s often because it’s "runaway"—meaning it's trying to use 100% or more of your processor power. In Activity Monitor, you’ll see the process name. Sometimes it’s not even the app itself, but a sub-process like "Google Chrome Helper" or a specific plugin.
To kill it, highlight the process and click the X icon at the very top of the window.
You’ll get two choices: "Quit" or "Force Quit." If you’re here, you want Force Quit. This is particularly useful for killing background processes that don't have a Dock icon, like a stuck print job or a cloud syncing tool that’s gone rogue.
What if the Keyboard and Mouse Stop Working?
This is the nightmare scenario. You're staring at a frozen screen, the clock isn't ticking, and how to force quit a program on Mac doesn't matter because the computer won't listen to you.
Before you pull the plug, try the "Force Restart" shortcut.
Press Control + Command + Power Button (or Touch ID button).
This forces the Mac to restart without asking you to save anything. It's a hard reset. It’s better than pulling the power cable because it still allows the hardware to cycle down somewhat gracefully, though you will definitely lose any unsaved work in any open app.
If even that fails, you have to hold the Power/Touch ID button down for about 10 seconds until the screen goes black. Only do this as a last resort. Modern SSDs (Solid State Drives) are resilient, but interrupting a write process at the wrong microsecond can occasionally lead to file system errors.
The Terminal Approach (For the Brave)
If you want to feel like a hacker—or if the graphical interface is so lagged that you can't click anything—the Terminal is your friend.
Open Terminal and type top. This shows you a live list of everything running. Look for the PID (Process ID) of the frozen app. It’ll be a number like 482.
Press q to exit the list view, then type:kill -9 482
The -9 flag is the "non-catchable, non-ignorable kill." It tells the kernel to stop the process immediately. No cleanup, no questions. It’s the digital equivalent of a guillotine.
Why Do Apps Freeze Anyway?
It’s rarely just "bad luck."
- Disk Space: If your SSD has less than 10-15% free space, macOS can't create "swap files" effectively. This leads to massive slowdowns and frequent app freezes.
- RAM Pressure: If you're running 16GB of RAM but your workflow needs 32GB, the system starts compressing memory. If it can't compress enough, things hang.
- Incompatible Plugins: This is huge in creative apps like Photoshop or Premiere. One bad third-party plugin can take down the whole ship.
- Outdated Software: If you just updated macOS but haven't updated your apps, you’re asking for trouble.
Immediate Next Steps to Take Now
Once you’ve successfully forced a quit, don't just jump right back into the app and hope for the best.
First, relaunch the app while holding the Shift key. In many applications, this prevents the app from trying to "restore" the windows and state it had when it crashed. If the crash was caused by a specific corrupted file you were opening, this prevents a crash loop.
Second, check your Updates in the App Store or the app’s own internal menu. Developers push "stability fixes" constantly. If you're three versions behind, you're essentially volunteering to be a crash-test dummy.
Finally, if a specific app keeps freezing, go to ~/Library/Preferences and try moving the .plist file associated with that app to the Trash. This resets the app's settings to factory defaults without deleting your actual work files. It’s a classic "old school" Mac fix that still works wonders in 2026.

If the freezing is system-wide and happens across different apps, it's time to run Disk Utility. Open it, select your "Macintosh HD," and click First Aid. It’ll check for directory errors and permission issues that might be causing the hang-ups. Keep your drive lean, keep your apps updated, and remember Command-Option-Escape. It’ll save your sanity.
