Open Terminal: Open Finder, go to “Applications,” then “Utilities,” and launch “Terminal.”
Type the Command: Type the command killall AppName (replace “AppName” with the name of the app you want to close) and press Enter.

This command sends a signal to all processes with the specified name to terminate immediately.

8.2. Using the `pkill` Command in Terminal

The pkill command in Terminal allows you to terminate processes based on various criteria, such as user, terminal, or command name:

Open Terminal: Open Finder, go to “Applications,” then “Utilities,” and launch “Terminal.”
Type the Command: Type the command pkill -u username AppName (replace “username” with your username and “AppName” with the name of the app you want to close) and press Enter.

This command sends a signal to all processes with the specified name and user to terminate immediately.

8.3. Creating a Custom Force Quit Script

You can create a custom script to automate the process of force quitting apps:

Open TextEdit: Open TextEdit and create a new document.
Type the Script: Type the following script:

#!/bin/bash
APP_NAME="$1"
if [ -z "$APP_NAME" ]; then
  echo "Usage: force_quit_app AppName"
  exit 1
fi
killall "$APP_NAME"
echo "Force quit $APP_NAME"

Save the Script: Save the document as force_quit_app.sh in a directory of your choice.
Make the Script Executable: Open Terminal and type the command chmod +x /path/to/force_quit_app.sh (replace /path/to/ with the actual path to the script) and press Enter.
Run the Script: To force quit an app, type the command /path/to/force_quit_app.sh AppName (replace /path/to/ with the actual path to the script and “AppName” with the name of the app you want to close) and press Enter.
