How can I Find and Terminate the Process that is Locking Port 3000 on a Mac?

To identify and terminate the process using port 3000 on a Mac, open the Terminal and check which process is occupying the port. This will provide you with the process name and its unique identifier (PID). Once you have the PID, use a command to stop that process. Finally, verify that the port is no longer in use by checking it again. Be cautious when forcefully stopping processes, as it can lead to data loss or other issues if the process was performing critical tasks.
