It is best to quit applications that you are not working with. Having several applications running can slow down your computer and make things messy. In this video, learn a few ways to quit applications properly. Also, see how to force an application to quit if it does not shut down normally.
- [Instructor] I'm starting this video with lots of applications running, because I want to talk about how to quit applications. You should quit applications that you're not currently using. Now, remember you know an application is running because it has the little block dot underneath the icon in the dock. Usually there will also be a window on the screen for that application, but you can't depend on that. Finder, for example, can run even though it does not have a window open on the screen. Also, it's important to note that only one application can be active at a time.
That's the application that has its menus up at the top of the screen. I know Dictionary is active, because this first menu is labeled Dictionary, and also the Dictionary window is on top of all of the others. Let's click on the Safari window, which I can see here. When I click on that, we'll see that it makes Safari active. That window comes to the top of the stack and I can see its menus up at the top of the screen. So when an application is active, you can go into the menu with the application's name and one of the options in this menu is Quit.
And there's also a keyboard shortcut listed here, Command + Q. So if I want to quit Safari, I can just hit this item on the list. That application is quit, the window is gone, and the little black dot is gone from the icon on the dock. Next, I want to quit Calculator. So I'm gonna click on that to make it active, this time I'll just use the keyboard shortcut, Command + Q, so I'll hold the Command key, tap the letter Q, and that quits that application. So I just quit the Calculator app, but I want you to notice something pretty important.
The icon for Calculator was not in the dock before I launched the application. Now that we've quit it, it is still visible in the dock over here, but only temporarily. This section of the dock to the right of this dividing line, is going to show recently used applications. So even after you quit them, the three most recent icons, as long as they are not icons that have been stored permanently in the dock, those are going to stay here in this recent section.
As you use other applications, these will cycle through, because it only shows the three most recent icons. All right, now let's quit the Dictionary. Another way to quit an application is to just right click on the icon for it in the dock, and if it's currently running, you'll see an option to quit it. So I'll click on that, and now Dictionary has quit. The icon is still here in the recent section, though. All right, so we've seen a few normal ways to quit an application, but sometimes you will try to quit an application and it simply won't quit.
This is rare, but it is a glitch that happens sometimes. Usually you should just give the computer a minute, but if the application still does not quit, you can force it to quit. For that we'll go into the System menu, that's the menu with the little Apple logo. Then we'll go to Force Quit. And this brings up a list of all of the applications that are currently running. And if one of these will not quit, you can select it here. So I'll select Chess, and then I can force it to quit. Hit this button, Confirm, and now it has forced that application to quit.
So now we have quit everything except for Finder. But Finder is always running. You cannot quit it, so you're not able to Force Quit it, either. But there is an option to restart it. So you could select it here and hit Relaunch if you're having some problem with Finder and you just need it to restart. And for now, I'll just close this window. Please keep in mind these different methods for quitting applications. It's best to quit applications if you're not using them.
