How to Check Which Process Owns a Port on Mac

You can check the port that a process owns on a Mac by following these steps:

1. Open the Terminal app on your Mac.

2. Type the command 'lsof -i :port_number' (replace 'port_number' with the actual port number you want to check) and hit Enter.

3. The command will display a list of processes that are using the specified port. Look for the process that you are interested in and note down its PID (process ID) number.

4. Type the command 'ps -p PID' (replace 'PID' with the actual PID number you noted down) and hit Enter.

5. The command will display information about the process, including its name and other details.

6. You can also use the 'netstat' command to check the status of all open ports on your Mac. Type 'netstat -an | grep LISTEN' and hit Enter to display a list of all open ports and the processes that are using them.
