How to Force Quit App on Mac (Even if Frozen or Force Quit Not Working)

If an app on your Mac is frozen or unresponsive—or you just want to flex your Terminal skills—here are two ways to force quit applications on macOS.

1. Use the Apple Menu to Force Quit (GUI)

This is the simplest method and works 90% of the time.

1. Click the Apple logo in the top-left corner of your screen.
2. Select Force Quit.
3. Choose the application you want to close.
4. Click Force Quit, then confirm by clicking Yes.

✅ This is ideal for quickly handling frozen apps without needing any commands.

2. Use Terminal to Force Quit (Advanced / Cool Points Bonus 😎)

If GUI fails or you want to look like a hacker in front of your friends, here's the Terminal method:

Step 1: Open Terminal

Use Spotlight (⌘ + Space) and search for Terminal. It looks like this:

#
# Matrix-style black screen with white text—very hacker-chic.
#
`

Step 2: List Active Processes

Run this command to see what apps are actively using internet connections:

lsof -i

This will display a list of processes. Look for the name of the app you want to force quit.

Step 3: Kill the App

Now that you know the process name, run:

killall -9 <process-name>

Example: If you're trying to quit an app named Claude, you'd run:

killall -9 Claude

Boom 💥 — it's gone.

Summary: Two Ways to Force Quit on Mac

You can use either method depending on your mood, skill level, or desire to impress. If one doesn't work, try the other.

Bonus Rhyme to Remember 🧠

"Go to the Apple, hit Force Quit on it. Or use the Terminal, kill all with it."
