Use the Activity Monitor to terminate the process: Open the Activity Monitor through focus search, find the corresponding application process, and click the X button to end completely; 3. Restart the Mac: If the problem persists, restart can clear temporary failures and release system resources; 4. Check for updates or reinstall the application: Go to the App Store to update the system or application.

A frozen app on a Mac can be frustrating, but it's usually easy to fix. Here's what you can do to get things running again.

1. Force Quit the App

The quickest way to deal with a frozen app is to force quit it.

• Click the Apple logo in the top-left corner.
• Select Force Quit…
• Choose the unresponsive app from the list (it may say “Not Responding”).
• Click Force Quit .

Alternatively, use the keyboard shortcut:
Command (?) Option Esc , then select the app and click Force Quit .

If the app closes, try reopening it. Often, this resolves the issue.

2. Use Activity Monitor to End the Process

If the app doesn't respond to the standard force quit, it might still be running in the background.

• Open Activity Monitor (you can find it via Spotlight with Command Space , then type "Activity Monitor").
• Look for the app in the list—check under the Process Name column.
• Select it, then click the X button in the top-left corner.
• Confirm with Force Quit .

This kills the process completely and frees up system resources.

3. Restart Your Mac

If the app keeps freezing or your whole system feels sluggish:

• Save any open work in other apps.
• Click the Apple logo and choose Restart .

A restart clears temporary glitches, resets system memory, and often resolves underlying issues causing apps to freeze.

4. Check for Updates and Reinstall if Needed

Frequent freezing might be due to software issues.

• Go to the App Store > Updates tab to check for app or macOS updates.
• If the app continues to freeze, consider deleting and reinstalling it:
  • Drag the app from the Applications folder to the Trash.
  • Download a fresh copy from the official source or App Store.

Outdated or corrupted app files are common causes of instability.

Keep an eye on apps that freeze repeatedly—they might not be optimized for your macOS version. Also, make sure your Mac isn't running out of memory or storage, as that can cause apps to hang.
