Task Manager on Mac: How to Open It (Activity Monitor Shortcut & Force Quit Guide)

If you’re looking for the Task Manager on a Mac, here’s the quick answer:

• Press Command (⌘) + Option (⌥) + Esc to open the Force Quit window
• Or open Activity Monitor (the full Mac Task Manager)

This is the fastest way to do the equivalent of Ctrl + Alt + Delete on a Mac.

The Force Quit window is the fastest way to close frozen apps, while Activity Monitor gives you full control over CPU, memory, disk, and network usage.

Below, we’ll show you exactly how to use both.

Task Manager Mac (Quick Answer)

On a Mac, there isn’t a tool called “Task Manager” like on Windows.

Instead, macOS has two equivalents:

• Force Quit Applications → Quick way to close frozen apps
• Activity Monitor → Full system monitor (like Task Manager)

If an app is frozen, start with Force Quit
If your Mac is slow, use Activity Monitor

How To Force Quit Apps on a Mac (Fastest Method)

The Mac Task Manager keyboard shortcut (⌘ + ⌥ + Esc) is the quickest way to close frozen apps.

This opens the Force Quit window showing all active apps. Those that have frozen or are slow may show “not responding” next to them.

Simply select the app and click “Force Quit” to close it.

If Finder itself is frozen, select it and click Relaunch

When to use this:

• An app is frozen or not responding
• You can’t click anything inside the app

Limitation:

This doesn’t show system processes or resource usage – for that, you need Activity Monitor (see guide below).

Where Is Task Manager on a Mac?

The full version of Task Manager on a Mac is called Activity Monitor.

It shows:

• CPU usage
• Memory (RAM) usage
• Energy impact (important for MacBooks)
• Disk activity
• Network activity

How To Open Activity Monitor (3 Ways)

1. Spotlight Search (Fastest)

Press ⌘ + Space, type Activity Monitor, press Enter

2. Finder

Go to:
Applications > Utilities > Activity Monitor

3. Launchpad

Open Launchpad → Search for “Activity Monitor”

How To Use Activity Monitor (Like Task Manager)

Activity Monitor shows everything running on your Mac. It’s useful if your Mac is slow, overheating, or draining battery.

How To Check CPU Usage (When Your Mac is Slow)

Open Activity Monitor → Click CPU

• Look for apps using a high % of CPU
• Anything consistently above 70–80% can slow your Mac

To close it, double click on the Process and click “Quit”.

Tip: If your browser such as Chrome or Safari is using high CPU, it’s often due to a specific tab – try closing tabs before quitting the whole app.

How To Check Memory Usage (When Apps Crash)

Click the Memory tab

Focus on:

• Memory Pressure (graph)
  • Green = OK
  • Yellow = Strained
  • Red = Problem
• Swap Used
  • High swap = your Mac is running out of RAM

If memory pressure is high (i.e. Yellow or Red), close heavy apps like browsers or editing software.

Tip: High memory usage is normal on Macs – focus on memory pressure, not just RAM numbers.

How To Check Energy Usage (Battery Drain Issues)

Click the Energy tab

Look for apps with high Energy Impact or those that are highlighted in red as “Not Responding”.

This is especially important on Apple Silicon Macs (M1–M5), where some apps can still drain battery quickly if not optimized.

Tip: Apps with high Energy Impact can quickly drain battery even when running in the background.

How To Check Disk Activity

Click the Disk tab

If you click on the “Bytes Written” column and order them in descending order, you can see which apps are accessing your hard drive the most.

This is useful if:

• Your Mac is slow when opening files
• You hear constant disk activity

If you want to keep an eye on disk activity without having to open Activity Monitor all the time, go to the Menu Bar and click on View > Dock Icon > Show Disk Activity

And a mini-graph will sit in your dock showing you disk activity in real time:

How To Check Network Usage

Click on the Network tab

If you click on the “Sent Bytes” column it will show you which apps are sending and receiving the most data over the internet.

This is useful for:

• Slow internet
• Background downloads
• Identifying which apps are frequently sending/receiving data

Force Quit vs Activity Monitor (What’s the Difference?)

As you can see in the comparison table below, the Force Quit window is very limited in what it can provide compared to Activity Monitor which is a far more powerful too.

Feature	Force Quit Window	Activity Monitor
Shortcut	⌘ + ⌥ + Esc	No
Close frozen apps	✅	✅
See CPU usage	❌	✅
See memory usage	❌	✅
View all processes	❌	✅

What To Do If Your Mac Freezes Completely

If you can’t open Task Manager or anything else:

Try this in order:

1. Press ⌘ + ⌥ + Esc → Force Quit
2. Press ⌘ + Control + Power → Restart
3. Hold the Power button until Mac shuts down

Only use force shutdown as a last resort (you may lose unsaved work)

Using Terminal as a Task Manager (Advanced)

You can also monitor processes using Terminal:

1. Open Terminal (Applications > Utilities)
2. Type: top
3. Press Enter

This shows all running processes in real-time.

To force quit an app:

1. Find its PID (Process ID)
2. Type: kill -9 PID

This is more advanced but useful if the interface is unresponsive.

Common Task Manager Problems on Mac (And Fixes)

Try some of these if you have any problems using

Force Quit not working

• Try Activity Monitor
• Restart Mac

Activity Monitor not opening

• Use Spotlight
• Restart Finder

Mac still slow after closing apps

• Restart
• Check login items

Final Tip

If your Mac frequently slows down or freezes, Activity Monitor can help you identify problem apps – especially ones not optimized for newer macOS versions or Apple Silicon Macs.

In many cases, closing just one misbehaving app can instantly speed up your Mac.
