Part 1. Is It Safe to Force Quit the Frozen Programs?

Many users think it is harmful to force quit the frozen programs or applications on their Mac, for it is stated that an abnormal close will easily cause a system error. That’s true. Forcing Mac to shut down the frozen application does figure out the problem but may have after-effects. When you close a program in a traditional way, it will remind you to save your work before eliminating everything it runs in the background. However, when you forcibly close it on your Mac, you may lose your files and data, even worse, causing a mess related to this program on the drive.

Anyway, you should first know that forcibly shutting down a frozen application is the same as killing the virus in the initial stage when you get sick. You leave no chance for it to develop. We need to see the great picture and find out the reasons why this situation would happen, and then what should we do to repair it and avoid it from happening again. In that way is your Mac being well protected.

One likely reason for the unresponsive program on your Mac is that you don’t have enough storage-RAM. Many applications operate themselves by producing some temporary files or other folders. If your Mac doesn’t have sufficient memory or is fully stuck by a variety of applications, files, or folders, then when you either try to launch one or more programs at the same time or open multiple websites in a browser, the programs and websites are hard to respond. Or we should say, your Mac has insufficient memory for them to operate their containing files. That’s a similar reason for your Mac’s slow running. Thus, always optimize and clean up your Mac, releasing more space by deleting those unwanted apps or unnecessary files. Here recommends a powerful All-in-one tool-iMyMac PowerMyMac for you to regularly optimize and clean up your Mac. Just a few simple clicks to free up your Mac storage space, protect your privacy as well as speed up your MacBook or iMac.

5. Use the Terminal & Kill Command

If a normal force quit does not work, or you prefer to shut down the app by a command line method, you can try to use the Terminal. What you should do is to:

  • Open the Terminal utility. (By default, this is under the Utilities folder, which located in the Applications folder.)
  • Type top and press the Return button. (The top command will lead to the information about those currently running)
  • Locate the program that you want to close under the column titled “COMMAND”. (The COMMAND list may use a short or truncated name for the program. Look for a name that looks similar to the program that you’d like to quit.)
  • Look for the PID (Process ID). Once you find the name of the would-like quit program, look for the number to the immediate left of it under the PID column. And then write down the PID number for the following use.
  • Type kill ###. Replace the ### with the PID number that you just wrote down. (For instance: If you were trying to close Skype, and the PID number you wrote down in the last step was 3562, then you should type kill 3562.)
  • Type sudo kill-9 ###if the program does not respond to the kill
  • Exit the Terminal after the application has been closed successfully.
