Note that you can’t remove built-in applications by doing this. For example, try to move the Chess app to the trash and you’ll see a message saying, “Chess can’t be modified or deleted because it’s required by OS X.” How to Remove Left Behind Files. The above method doesn’t actually erase an application’s preferences. Select the window or program to close and then select End Task. Repeat these steps for each window or program you want to close. Choose Force Quit from the Apple menu (or simultaneously press the Command + Option + Esc keys). In the Force Quit Applications window, select the program and select Force Quit. Note: I used the Rocket app as an example in my pictures, but only because I was removing an earlier version. I love Rocket and would never delete it (it emojifies your Mac!). How to close an app that you thought was already closed or can't figure out how to close on your Mac. Click on the Finder icon in your app dock.

Mac App Store Won't Open

It may not be often that you find your Mac with many open Finder windows or multiple windows of Safari or any other app. But when you do and you want to close them all at once, you have two options.

The first is the Command + Option + W. The second one involves mouse clicks. If you’re not the three-key-shortcut type, you’ll want to check out how to close all windows of a Mac app (including Finder) with this keystroke + click.

How to Close all Windows in Mac App with Keystroke+Click

Note that this method works for all Finder Windows or multiple instances/windows of other apps (including browsers etc).

#1. With the app/Finder open, click on File from the top menu.

#2. Now, press the Option/Alt key on your Mac keyboard.

#3. You should notice that the Close option changes to Close All.

#4. Click on Close All and all the windows will be quit/closed.

That’s it. Being a keyboard-shortcuts guy, I’ve wondered if this one helps. But I realize, of late, that this tip will be helpful for those working their mice a lot (I’m thinking digital artists).

There is one interesting exception to this though. While in Finder, or Chrome the default option is Close and the Close All (or Close All Windows) option shows only when you press Alt/Option. But in Safari, when you have multiple windows/instances open, you will notice that Close All Windows shows up even without pressing the Alt/Option key.

You should remember that this method will close windows, which means all unsaved work will be lost. For instance, if you’ve got multiple websites open in different windows of Chrome, closing all windows will lose all the open data. By default, browsers only ask you when you try to close multiple tabs so even this feature won’t save data. /preview-app-on-mac.html.

The method didn’t work for apps like Microsoft Word in Yosemite so the implementation seems to be specific to some apps.

When you click the red button at the top left corner of a window on a Mac, you close that window. But sometimes this also quits the app entirely. There is a logic behind this, based on how the app operates. Apps that allow multiple windows for multiple documents usually only use the red button to close a window. But apps that normally operate with a single window and have no other reason to stay open, will quit.

Video Transcript: So every once in awhile I get somebody asking about what actually happens when you click the red close button to close a window in an application on the Mac. The confusion comes from the fact that sometimes this seems to quit the app and sometimes it doesn't quit the app. So, for instance, here I am in Safari and if I click the red button I can see Safari is still the app that's running. I can create a new window in Safari. I'm still looking at Safari menu items here at the top. I'm still in Safari. But then other apps don't act this way.Here's the Contacts app. You can see I'm running Contacts. Here's the Contacts window. If I click the red button here Contacts actually closes. The entire application quits. Why is there a difference between how some apps act when you click the red button and other apps? So there is kind of a logic that apps play by when determining what happens when you click that red button. It has to do with, what I call, single window apps. Whether or not an app really consists of a single window or whether there are multiple windows containing multiple documents used by the app.So, for instance, Contacts is a single window app. There's one window here that shows you your contacts and you can go and click on different ones and it displays the contact to the right. It's a single window. When you click the red button you close that single window so it quits. Other apps have multiple windows usually because you can have multiple Docks open.For instance the easiest way to demonstrate this is an app that undoubtedly shows you one window per document. Here's Pages and we create a window that has this one document in it. If I create a new document it's in a second window. I have two windows right now running in Pages. Now you would imagine that when you click the red button you don't want Pages to quit because you have another document open. You may have three or four documents open. You certainly don't want the entire app to Quit just because you closed one window or one document. So it goes to follow that they should be consistent and even when there's one window left when you close that one window the app stays open. After all you may be closing that document in order to simply go ahead and open another one. So the app doesn't quit. You have to go to the Menu and Quit or use Command Q to actually quit the app.So we can look at other apps and see how they work. For instance, Notes seems to be a single window app. Sure enough if I click the red button there Notes quits. Now if we go to something like TextEdit that has multiple windows. There's a document. There's another document. Of course whichever one of those I close it's not going to quit the app. I close the last one and it still doesn't close the app. I actually have to Quit it by itself.Then there are apps that kind of fall in-between. Sometimes you can rationalize why they don't work this way. So you have iTunes. iTunes seems to be a single window app. After all there is no way for me to open up a second main iTunes window. But if I click the red button it doesn't quit. Well, this kind of makes sense because first of all there are two windows that you can have. That you can switch between. So I could go to Window and open the iTunes window or I can switch to MiniPlayer and bring that up. That's a second window and if I close this first window the MiniPlayer stays open. If I close the MiniPlayer it actually automatically opens the main window. So it's kind of a little bit beyond a single window app. Plus the fact that of course if I'm playing music in iTunes and I want to close the window to get it out of the way I don't want iTunes to quit because the music will stop playing. So it makes sense in that case.There are some definite exceptions though. In Calendar you've got what looks like a single window app but if you click the red button it doesn't quit Calendar. I can go to Window, Calendar. Now you can rationalize this a little bit because there is something called the Availability Panel. You bring that up and that's a kind of useful thing all on its own. So closing the main Calendar window to have your Availability Panel open it does kind of make sense. It might be the reasoning why Calendar doesn't behave like a single window app.Of course Safari is an app where you definitely, very often, have more than one window open. So even though these technically aren't documents, they're webpages, they're like documents. So you close one window, close another window, you're still in Safari. It's very likely when you close a window in Safari that you may decide you want to open another one right away. You don't want to Quit the app and have to go and restart it. Whereas in some of these apps, like in Contacts, you're not going to go and say well I want to go and view another contact. Let me close this window just to go back to the same window. If you think of it in terms of that rule then it actually makes sense. So that's why Contacts quits like that. There are other apps too. News is like that as well. There's a single window for News. If I click to close that then News Quits because it wouldn't make sense to close the News window only to reopen it again to go to another location.So various apps do various different things. For the most part there's some logic behind it. It seems like in all cases when an app can deal with multiple windows and multiple documents clicking the red button will not Quit the app. It seems like in most cases when it looks like it's a one window app clicking the red button will Quit the app. There are a few exceptions and these exceptions kind of can be rationalize a little bit to make sense. So I hope that explains it. It really doesn't change much about how you use your Mac. But it's interesting to look at.
