5 Ways to Force Quit Apps on Mac | Shortcuts, Activity Monitor, and Terminal Commands

An app freezes. The spinning beach ball appears and just keeps spinning. Clicks do nothing, the window goes white, and macOS offers no obvious escape route. If this sounds familiar, you're not alone — and you don't need to panic. Mac gives you five different ways to force quit a frozen app, ranging from a simple three-key shortcut to Terminal commands that work even when the entire GUI is unresponsive. This guide covers all five methods, plus what to do when the whole Mac — not just one app — refuses to cooperate.

Before you force quit an app on Mac

When force quitting is necessary

Most app hangs on Mac follow a recognizable pattern. You'll know it's time to force quit when you run into any of the following:

The spinning beach ball won't stop: the rainbow-colored cursor (also called the "spinning wheel of death") rotates endlessly and the app ignores all clicks
"Application Not Responding" in the Dock: hovering over the app's Dock icon shows this label in its tooltip
A blank or black window: the app's window stops drawing its contents and becomes completely unresponsive
Sudden full freeze: the app accepts no keyboard or mouse input whatsoever

In any of these states, the normal Quit command (Command + Q) won't work — the app can't process it. Force quitting bypasses the app entirely and tells macOS to terminate the process directly.

Risks of force quitting

Force quitting is a last resort, and there's one risk worth understanding before you pull the trigger.

Any unsaved work in the frozen app will be lost. If you were editing a document that hasn't been saved, those changes are gone once the process is killed. Before force quitting, it's always worth trying Command + S one more time — on rare occasions the save command gets through even when the app appears frozen. Apps with AutoSave support (Pages, Numbers, Keynote, and recent versions of Microsoft Office) can often recover to their last autosave point, but that's not guaranteed.

Comparison of the 5 methods

Method	Speed	Difficulty	Best for
① Command + Option + Esc	Fastest	Easy	First thing to try in any freeze
② Dock → Option + right-click	Fast	Easy	When the Dock is accessible
③ Apple menu → Force Quit	Fast	Easy	When the menu bar is accessible
④ Activity Monitor	Moderate	Intermediate	Identifying CPU/memory hogs
⑤ Terminal kill command	Moderate	Advanced	When the GUI is completely unresponsive

The recommended approach is to start with Method 1 and work down the list only if the previous method doesn't work. The vast majority of freezes are resolved by the keyboard shortcut alone.

Method 1: The Command + Option + Esc shortcut

This is the most reliable and fastest way to force quit a frozen app on Mac. When an app stops responding, this should always be your first move.

Press Command (⌘) + Option (⌥) + Esc simultaneously on your keyboard
The "Force Quit Applications" dialog opens
Select the frozen app from the list — unresponsive apps typically appear in red with "(not responding)" next to their name
Click the Force Quit button in the lower right
If a confirmation dialog appears, click Force Quit again

This dialog is a lightweight system-level panel, which means it can open even while an app is fully frozen. You can also force quit multiple apps in sequence without closing the dialog between each one — just select the next app and click Force Quit again.

A note on Finder: if you select Finder in this dialog, the button label changes from "Force Quit" to "Relaunch." Finder is a special system process that immediately restarts itself after being killed, so you'll see your desktop disappear for a moment before it comes back. This is normal and safe.

Takeaway: Command + Option + Esc opens the Force Quit dialog from virtually any situation. Selecting the frozen app and clicking Force Quit resolves the overwhelming majority of Mac hangs.

Method 2: Option-right-click the Dock icon

If you prefer the mouse over the keyboard, this method lets you force quit an app directly from the Dock without opening any dialog.

Locate the frozen app's icon in the Dock
Hold down the Option (⌥) key on your keyboard
While holding Option, right-click (or Control + click) the app's icon
In the context menu, the usual "Quit" option will have changed to "Force Quit" — click it

Without holding Option, the context menu only shows the standard "Quit" command. The Option key is what unlocks Force Quit in the Dock menu. This works even if the app's icon is bouncing or showing the active indicator dot while the app is unresponsive.

This method is particularly handy for users who are more comfortable with the trackpad or mouse than with keyboard shortcuts, and it skips the confirmation dialog for a faster result.

Takeaway: Hold Option, then right-click the Dock icon — "Quit" becomes "Force Quit." It's the quickest mouse-only approach when the Dock is accessible.

Method 3: Force Quit from the Apple menu

The Apple menu (🍎) in the top-left corner of the screen provides the same Force Quit dialog as Method 1, accessible through a point-and-click menu path.

Click the Apple (🍎) icon in the top-left corner of your screen
Select "Force Quit…" from the dropdown menu
The "Force Quit Applications" dialog opens — it's the same window as Method 1
Select the frozen app and click Force Quit

There's also a power-user shortcut worth knowing for this section. Command (⌘) + Option (⌥) + Shift + Esc, held for about one second, instantly force quits whatever app is currently in the foreground — no dialog, no confirmation. This works well when the frozen app has focus and you want to terminate it immediately without switching away.

Use this instant-kill shortcut with care. Because there's no confirmation step, it's easy to accidentally quit the wrong app if another window sneaks into focus. Reserve it for situations where you're certain which app needs to go and the normal dialog is taking too long.

Takeaway: Apple menu → Force Quit gives you the same dialog as the keyboard shortcut. Command + Option + Shift + Esc (held 1 second) is the no-dialog fast track for the frontmost app.

Method 4: Quit via Activity Monitor

Activity Monitor is Mac's built-in task manager. It shows every process running on the system and lets you see exactly how much CPU and memory each one is consuming — making it the right tool when you need to identify which process is causing problems before killing it.

Open Activity Monitor: go to Launchpad → Other → Activity Monitor, or use Spotlight (Command + Space) and type "Activity Monitor"
In the process list, find the app you want to quit — use the search field in the top right to filter by name
Click the process to select it
Click the X (Stop) button in the upper-left area of the toolbar
Choose either "Quit" (sends a normal quit signal, giving the app a chance to clean up) or "Force Quit" (kills the process immediately)

Activity Monitor's real value lies in the diagnostic information it provides alongside the force-quit capability.

Sort by the CPU column to immediately spot any process consuming close to 100% — a common sign of a runaway app or an infinite loop
Sort by the Memory column to find memory leaks or apps that have ballooned in RAM usage over time
Apps labeled "(Not Responding)" in red are confirmed as frozen and safe to force quit

Activity Monitor is also the only GUI method that lets you terminate background helper processes or system agents that don't appear in the Dock or in the standard Force Quit dialog.

Takeaway: Activity Monitor handles diagnosis and termination in one window. If your Mac feels sluggish but no single app seems obviously frozen, start here to find the offender.

Method 5: Kill the process from Terminal

When the GUI is completely unresponsive — no Dock, no menu bar, nothing clicking — Terminal is your last resort. If you can open a Terminal window, you can force quit any process from the command line. This is an advanced method, but it's worth knowing.

Open Terminal via Launchpad → Other → Terminal, or Spotlight (Command + Space, then type "Terminal").

Step 1: Find the process ID (PID)

Use ps aux piped through grep to locate the frozen app's process ID:

ps aux | grep AppName

For example, to find Safari:

ps aux | grep Safari

The output lists one or more lines. The number in the second column is the PID you need.

Step 2: Send a graceful quit signal (kill)

kill <PID>

This sends SIGTERM — a polite termination request that gives the app a chance to save state and clean up before exiting. Try this first if you want to preserve any autosave data.

Step 3: Force kill if needed (kill -9)

kill -9 <PID>

This sends SIGKILL, which immediately terminates the process with no cleanup. The app cannot catch or ignore this signal, so it works even on a fully frozen process. Use this when kill without -9 doesn't work.

Kill by name with killall

If you don't want to look up a PID, killall lets you terminate a process by name:

killall Safari

killall "Google Chrome"

App names that contain spaces must be wrapped in double quotes. To force-kill by name, add the -9 flag:

killall -9 "Google Chrome"

killall terminates all processes matching that name simultaneously, which is useful when an app has spawned multiple helper processes.

Takeaway: kill -9 <PID> or killall -9 AppName are the go-to Terminal commands for force quitting. Keep this method in your back pocket for emergencies when the GUI is completely unworkable.

Force shutting down an entirely frozen Mac

Sometimes it's not a single app that's frozen — it's the entire Mac. Here's how to tell the difference, and what to do when the whole system is unresponsive.

App freeze vs. full system freeze

Before reaching for the power button, take a moment to assess the situation:

Mouse cursor still moves — macOS itself is running fine. One app is frozen, but the system is healthy. Try Methods 1–5 above.
Mouse cursor is frozen / screen is completely locked up — the whole system has hung. Use the hardware shortcuts below.
Screen went black — could just be the display sleeping. Press a key or click the trackpad first to rule out sleep mode before assuming it's a freeze.

Hold the power button (force shutdown)

This is the last-resort option when everything else has failed.

Press and hold the power button for approximately 10 seconds (on MacBooks, this is the Touch ID button)
The screen will go dark and the Mac will shut down forcibly
Wait a few seconds, then press the power button once to start it back up

This works on both Apple Silicon Macs (M1/M2/M3/M4) and Intel Macs. All unsaved data will be lost. Use it only when the system is completely unresponsive to any other input.

Control + Command + Power (force restart)

If you want to restart immediately rather than shut down and manually power back on:

Press Control (^) + Command (⌘) + Power button simultaneously
The Mac restarts immediately, without saving prompts

Note that on some Apple Silicon models, this shortcut may behave differently or not respond. If it doesn't work, fall back to the power button hold.

Control + Option + Command + Power (graceful shutdown)

This is a slightly gentler option that attempts to close open apps before shutting down:

Press Control (^) + Option (⌥) + Command (⌘) + Power button simultaneously
macOS sends a quit signal to open apps — some may show a save dialog
The system shuts down after apps have closed

This shortcut only works if the system is partially responsive. If your Mac is completely frozen, it won't register, and you'll need to hold the power button instead.

SMC and NVRAM resets

If your Mac freezes repeatedly — not just once — a deeper hardware-level reset may be needed. Apple offers two types: SMC reset (System Management Controller, handles power and thermal management) and NVRAM reset (stores certain system settings). The exact steps differ between Apple Silicon and Intel Macs, and Apple publishes up-to-date instructions for each model on its support site. Search "reset SMC Mac" or "reset NVRAM Mac" on Apple's support pages for your specific model.

Common questions

Will I lose data when I force quit?

Yes — any changes that haven't been saved to disk at the moment of force quit are lost. This is the main downside of the method. However, apps that support AutoSave (Pages, Numbers, Keynote, and modern versions of Microsoft Word and Excel) may be able to recover to their last autosave checkpoint when you reopen them.

Before force quitting, always try pressing Command + S once more. In some cases the save command succeeds even when the app looks completely frozen, because the save logic runs on a separate thread from the UI.

What happens if I force quit Finder?

Nothing bad. Finder relaunches itself automatically and immediately after being force quit. You'll see your desktop icons and Dock disappear for a fraction of a second, then everything comes back as if nothing happened. No data is lost. In fact, force-quitting Finder is a common fix for a sluggish or glitching desktop — it's essentially the same as restarting Finder through the menu.

Why does my Mac keep needing force quits?

Occasional freezes are normal, but if a specific app hangs repeatedly, something is wrong. Work through these steps in order:

Update the app — check the App Store or the developer's website for a newer version
Delete the app's preferences file — look in ~/Library/Preferences/ for a .plist file named after the app and move it to the Trash
Reinstall the app — uninstall it completely and do a fresh install
Update macOS — system-level bugs that cause app instability are often fixed in point releases
Check available storage — macOS starts struggling when the boot drive has less than 10 GB free; reclaim space if you're running low
Check memory pressure in Activity Monitor — open the Memory tab and look at the Memory Pressure graph; if it's consistently red, you may need to close more apps or consider adding RAM

Is it different on Apple Silicon (M1/M2/M3) vs. Intel?

For force quitting apps — Methods 1 through 5 — there is no difference between Apple Silicon and Intel Macs. All the same keyboard shortcuts, menus, Activity Monitor steps, and Terminal commands work identically on both architectures.

The only area where chip type matters is system-level operations like SMC resets, which have different procedures on Apple Silicon versus Intel. For everyday app freezes, you don't need to think about which chip you have.

Should I restart after a force quit?

If you force quit a single app and the rest of the system feels normal, a restart is not required. Simply relaunch the app and continue working.

That said, a restart is a good idea in these situations:

You force quit multiple apps in a row
The Mac feels slow or unstable after the force quit
The relaunched app freezes again right away
You had to do a full system force shutdown or force restart

Restarting clears RAM, flushes system caches, and gives macOS a clean slate. It takes only a minute and often resolves lingering instability that a simple app relaunch won't fix.

Summary

Here's a quick recap of all five ways to force quit apps on Mac:

Command + Option + Esc — Opens the Force Quit Applications dialog. The fastest and most universal method; try this first every time.
Dock → Option + right-click → Force Quit — Mouse-only method that skips the dialog entirely. Works whenever the Dock is accessible.
Apple menu (🍎) → Force Quit — Same dialog as Method 1, reached through the menu bar. Command + Option + Shift + Esc (hold 1 second) instantly force quits the frontmost app with no confirmation.
Activity Monitor — Shows all running processes with CPU and memory data. Best when you need to diagnose which process is causing the problem before terminating it.
Terminal: kill -9 <PID> or killall -9 AppName — Works even when the entire GUI is unresponsive. The ultimate fallback for extreme situations.

The recommended escalation path is: Shortcut → Dock → Apple menu → Activity Monitor → Terminal. If the whole Mac is frozen and none of these methods work, hold the power button for 10 seconds to force a shutdown. The next time you see the spinning beach ball, reach for Command + Option + Esc first — it resolves most freezes in under five seconds.
