Task Manager on Mac: How to Open It and What to Quit

There is no app called Task Manager on a Mac. The Mac task manager is really two built-in tools: Force Quit Applications for a frozen app, and Activity Monitor for every process with its CPU, memory and energy use. Here is how to open both in a couple of seconds, which shortcuts matter, and how to tell what is safe to quit.

Quick answer

To open Task Manager on a Mac, press ⌘ Command + ⌥ Option + Esc. That opens Force Quit Applications, the Mac’s answer to Ctrl+Alt+Delete. For the full list of running processes with CPU and memory use, press ⌘ Command + Space, type Activity Monitor and press Return. Those two built-in tools do everything Windows Task Manager does.

Does a Mac have a Task Manager?

Not under that name. Windows puts everything in one app called Task Manager. macOS splits the same job between two tools that ship with every Mac, and has done since Mac OS X 10.3 in 2003, when Activity Monitor replaced the older Process Viewer (Wikipedia’s list of built-in macOS apps tracks that history):

Force Quit Applications: a small window that lists your open apps and closes a frozen one in two clicks. This is the fast path, and the one Windows switchers mean when they search “Ctrl+Alt+Delete on Mac”.
Activity Monitor: the full task manager. It lists every process, not just apps, with live CPU, memory, energy, disk and network numbers, and it can quit any of them.

Here is how each Windows Task Manager job maps onto the Mac:

What you did in Windows Task Manager	Mac tool	How to get there
End a frozen app (End task)	Force Quit Applications	`⌘ Command` + `⌥ Option` + `Esc`
See every process (Processes / Details tab)	Activity Monitor	`⌘ Command` + `Space`, type “Activity”
CPU and memory graphs (Performance tab)	Activity Monitor, bottom panel, or Window > CPU History	`⌘ Command` + `3` inside Activity Monitor
Battery drain per app (Power usage column)	Activity Monitor, Energy tab	Click Energy
Startup apps (Startup tab)	System Settings > General > Login Items & Extensions	Apple menu > System Settings
Services	Activity Monitor, View > System Processes	View menu

Force Quit Applications (left) is the fast list for a stuck app. Activity Monitor (right) is the full picture of every process, its CPU and memory use.

How to open Task Manager on Mac: 5 ways

The quickest way to open Task Manager on a Mac is Spotlight: press ⌘ Command + Space, type Activity and press Return. We ran every method below on a 16 GB M1 Pro MacBook Pro running macOS 27. The two keyboard routes are the quickest; the Finder route is the one to remember when Spotlight is misbehaving.

Use Spotlight. Press ⌘ Command + Space, type Activity, and press Return when Activity Monitor is highlighted. This is the fastest route to the full task manager.
Use the Force Quit shortcut. Press ⌘ Command + ⌥ Option + Esc for the quick Force Quit Applications window when all you need is to close a stuck app.
Use the Apple menu. Click the Apple menu in the top-left corner and choose Force Quit…. It opens the same window as the shortcut and works when the keyboard does not.
Use Finder. Open Finder, choose Go > Utilities (or press ⇧ Shift + ⌘ Command + U), then double-click Activity Monitor.
Keep it in the Dock. With Activity Monitor open, Control-click its Dock icon and choose Options > Keep in Dock. Next time it is one click away.

Activity Monitor on macOS 27 showing the CPU tab with kernel_task at 42.7% and WindowServer at 37.5% CPU, with numbered callouts on the stop button, tabs, % CPU column, CPU load panel and search field — Activity Monitor on our test Mac. (1) Stop button to quit the selected process, (2) the five tabs, (3) click % CPU to sort, (4) System, User and Idle load, (5) search by name. At capture time 1,015 processes and 5,509 threads were running.

What is the Task Manager shortcut on Mac?

The Task Manager shortcut on Mac is ⌘ Command + ⌥ Option + Esc. We confirmed every shortcut below in the live menus on macOS 27, and the core ones are also listed on Apple’s keyboard shortcuts page.

Shortcut	What it does	Where it works
`⌘ Command` + `⌥ Option` + `Esc`	Open Force Quit Applications	Anywhere
`⌘ Command` + `⌥ Option` + `⇧ Shift` + `Esc`	Force quit the frontmost app at once, no window, no confirmation	Anywhere (hold briefly)
`⌘ Command` + `Q`	Quit the current app normally, so it can ask to save	Any app
`⌘ Command` + `Space`, “Activity”	Open Activity Monitor	Anywhere
`⌥ Option` + `⌘ Command` + `Q`	Quit the selected process	Inside Activity Monitor
`⌥ Option` + `⌘ Command` + `F`	Jump to the search field to filter processes	Inside Activity Monitor
`⌘ Command` + `I`	Inspect the selected process (memory, open files, ports)	Inside Activity Monitor
`⌘ Command` + `2` / `3`	Floating CPU Usage / CPU History window	Inside Activity Monitor
`⌃ Control` + `⌘ Command` + Power	Force restart, without saving	Keyboards without Touch ID

The second row is the hidden one. Open the Apple menu and hold ⇧ Shift: Force Quit… turns into Force Quit [app name], and the menu shows its shortcut, ⌥ Option + ⇧ Shift + ⌘ Command + Esc. It skips the window entirely, so make sure the frozen app is the one in front before you press it.

Can you make Ctrl+Alt+Delete itself work? Not with a built-in setting. We tried the usual trick on macOS 27, an App Shortcuts override for the Apple menu’s Force Quit… item, and the Apple menu kept ⌘ Command + ⌥ Option + Esc. Your fingers adapt fast: the Mac keeps the same three-key habit, just on different keys. More in Ctrl+Alt+Delete on Mac.

How do I end a task on a Mac?

“End task” on a Mac is called Quit or Force Quit. Try them in this order, because each step is more forceful than the last:

Quit normally with ⌘ Command + Q. The app saves and closes itself.
Force Quit with ⌘ Command + ⌥ Option + Esc, select the app, click Force Quit. Unsaved work in that app is lost.
Quit a background process from Activity Monitor: select it, click the stop button, then Quit or Force Quit.
Use Terminal when the windows themselves will not respond:

Terminal

$ killall Safari

Ends every process named Safari. Names are case-sensitive; see the killall reference.

When an app quits normally, it can do what it needs to do before quitting, such as to save changes. So before you decide to force an app to quit, try to quit the app normally.

What is safe to quit in Activity Monitor?

It is safe to quit any app you opened yourself and anything marked (Not Responding). Never quit kernel_task, WindowServer or other macOS processes. This is the part most guides skip. Activity Monitor shows every process, not just apps. When we checked, 1,079 processes were running (1,015 in the screenshot taken a few minutes earlier) while only 12 apps had a Dock icon. The rest are parts of macOS or helpers of those apps, and quitting the wrong one can log you out or restart the Mac.

Usually safe to quit

Anything marked (Not Responding) in red
Apps you opened yourself, like a browser, Slack or a game
Helper processes named after those apps, such as Google Chrome Helper (Renderer), one per tab
A single app holding far more CPU than the rest for more than a few minutes

Leave alone

kernel_task: the core of macOS. High CPU here is often macOS cooling the Mac on purpose
WindowServer: draws everything on screen. Quitting it logs you out
launchd, loginwindow, mds_stores (Spotlight) and anything owned by root or _ users
Time Machine (backupd) mid-backup

In our screenshot above, kernel_task sat at 42.7% CPU and WindowServer at 37.5%, yet the Mac was 57.75% idle. Neither needed quitting. For any other name you do not recognise, our Mac processes list explains 369 macOS background processes in plain English and says whether to quit each one. A high number is only a problem when it stays high and the Mac feels hot, loud or slow.

How do I check memory and CPU usage?

Open Activity Monitor and click the Memory tab. Ignore how much RAM is “used”: macOS deliberately fills spare memory with cache. Look at the Memory Pressure graph at the bottom instead. Green is fine, yellow means the Mac is compressing and swapping, red means it needs more memory than it has. Our test Mac showed 13.65 GB used of 16 GB with green pressure, which is healthy. Full guide: How to check RAM usage on Mac.

You can use Activity Monitor to quit a process, even if it’s in a loop or not responding.

For CPU, click the CPU tab and then the % CPU column header. Remember that the figure is per core: on an 8-core Mac the ceiling is 800%, so one app at 120% is using just over one core. Full guide: How to check CPU usage on Mac.

Activity Monitor memory panel reading Physical Memory 16.00 GB, Memory Used 13.65 GB, Cached Files 2.20 GB, Swap Used 6.95 GB, App Memory 3.96 GB, Wired 3.09 GB, Compressed 6.00 GB, with a green memory pressure graph — The Memory tab’s bottom panel on our 16 GB test Mac. The pressure graph, not the used figure, tells you whether you are short of RAM.

Is there a better Task Manager app for Mac?

For most people the two built-in tools are enough, and they are free. Third-party options fall into three groups:

Type	Good for	Trade-off
Built-in (Force Quit + Activity Monitor)	Everything Windows Task Manager does	You have to know what the numbers mean
Menu bar monitors (such as iStat Menus or Stats)	Always-visible CPU, memory and temperature graphs	More numbers, not fewer
Plain-English watchers (such as Safe to Quit)	People who never want to open Activity Monitor	Answers “which app?”, not every metric

Avoid “Mac cleaner” apps that promise to free RAM. macOS manages memory itself, and forcing it empty just makes apps reload from disk.

Frequently asked questions

Is there a Task Manager on a Mac?

Not by that name. The Mac equivalents are Force Quit Applications (Command + Option + Esc) for closing a frozen app and Activity Monitor for the full list of processes with CPU, memory, energy, disk and network use.

What is the Ctrl+Alt+Delete for Mac?

Command + Option + Esc. It opens the Force Quit Applications window, where you select a frozen app and click Force Quit. See our Ctrl+Alt+Delete on Mac guide for remote desktop and virtual machine cases.

How do I open Task Manager on a MacBook?

Press Command + Space, type Activity Monitor and press Return. For just the quick force quit list, press Command + Option + Esc. Both work the same on every MacBook Air and MacBook Pro.

How do I end a task on Mac?

Press Command + Q to quit normally. If the app is frozen, press Command + Option + Esc, select it and click Force Quit. Background processes can be ended from Activity Monitor with the stop button.

What is Command+K on Mac?

It depends on the app. In Finder, Command + K opens Connect to Server; in many editors and chat apps it inserts a link or opens a quick switcher. Inside Activity Monitor, Command + K clears the CPU history graph.

Is Activity Monitor the same as Task Manager?

It is the closest match. Activity Monitor covers the Processes, Performance and App history parts of Windows Task Manager. Startup apps live separately in System Settings > General > Login Items & Extensions.

Is it safe to use Activity Monitor?

Yes. Looking changes nothing. The only risk is quitting system processes such as kernel_task or WindowServer, which can log you out or restart the Mac. Quitting apps you opened yourself is safe.
