如果您是Mac(Macs)和OS X的新手，您可能已经注意到Dock中的一些应用程序图标下方有一个小黑点。无论如何，黑点通常始终位于Finder图标下方。(Finder)
黑点基本上表示应用程序正在运行。这有点像当您在Windows中启动一个程序时，它会显示在任务栏上，下方有一条灰线。
在Mac上，大多数已安装的应用程序都列在Dock上，因此判断某些东西何时打开的唯一方法是更改图标。在OS X中，只需添加一个小黑点即可完成。
默认情况下，这些指标是打开的，总的来说，我发现它们非常有用。但是，如果您更喜欢简单地使用Mission Control或其他方法来查看您打开的应用程序，那么您可以在System Preferences中禁用黑点指示器。
禁用Dock中应用程序(Apps)的点(Dot) 指示器(Indicators)
为此，请单击左上角的Apple图标，然后单击(Apple)System Preferences。
在第一行，您应该会看到Dock的图标。
当您单击它时，您将能够调整与Dock相关的几个不同设置。我们感兴趣的主要内容在底部：显示打开应用程序的指标(Show indicators for open applications)。
取消选中该选项后，您将不再看到应用程序图标下的黑点。单击已打开应用程序的图标将带您进入该应用程序，就像以前一样。
如果您仍需要查看Mac上当前打开的应用程序，您可以使用Mission Control。只需(Just)使用三个或四个手指向上滑动，它就会向您显示所有打开的窗口，这些窗口在主区域中不是全屏的，并且顶部的任何全屏应用程序都以图标的形式显示。
最后，我有时会在Dock(Dock)设置中更改的另一个选项是Minimize windows into application icon。通常，当您在Windows(Windows)中最小化应用程序时，它只会转到任务栏中的图标，仅此而已。在Mac上，默认情况下它不会转到图标。相反，另一个图标被添加到停靠栏的右侧。
如您所见，如果我同时打开日历(Calendar)和记事本(Notepad)，然后将它们最小化，它会在最右侧创建另外两个图标。我觉得这很烦人，因为我习惯了只有一个像Windows这样的图标。当您在停靠设置中选中该选项时，它会将这些应用程序最小化到应用程序图标中，而不是单独使用。
由于Finder在(Finder)OS X中永远无法关闭，因此Finder图标下方将始终有一个黑点。希望随着您开始了解有关Mac的更多信息，它会变得更易于使用。享受！
What are the Black Dots Under App Icons and How to Remove Them
If you’re new to Macs and OS X, you may have noticed that some of your app icons in the Dock have a small black dot under thеm. The black dоt is normally always under the Finder icon no matter what.
The black dot basically indicates that the application is running. It’s kind of like when you launch a program in Windows and it shows up on the taskbar with a grey line underneath it.
On the Mac, most of the apps installed are listed on the Dock, so the only way to tell when something is open is by changing the icon. In OS X, it’s done by simply adding a small black dot.
By default, these indicators are turned on and overall, I find them pretty useful. However, if you prefer to simply use Mission Control or some other method to see your open apps, then you can disable the black dot indicators in System Preferences.
Disable Dot Indicators for Apps in Dock
To do this, click on the Apple icon at the top left and then click on System Preferences.
In the top row, you should see an icon for Dock.
When you click on that, you’ll be able to adjust several different settings related to the Dock. The main one we are interested in is at the bottom: Show indicators for open applications.
Once you uncheck that option, you will no longer see the black dots under the app icons. Clicking on an icon where the app is already opened will bring you to that app, just like before.
If you still need to view the currently open apps on your Mac, you can use Mission Control. Just swipe up using three or four fingers and it’ll show you all open windows that are not full-screen in the main area and any full-screen apps up at the top as icons.
Lastly, one other option that I sometimes change in Dock settings is Minimize windows into application icon. Normally, when you minimize an app in Windows, it simply goes to the icon in your taskbar and that’s it. On a Mac, it doesn’t go to the icon by default. Instead, another icon is added to the right side of the dock.
As you can see, if I open Calendar and Notepad at the same time and then minimize them, it creates two more icons at the far right. I find this annoying since I’m used to just having one icon like Windows. When you check that option in dock settings, it will minimize those apps into the app icon rather than separately.
Since Finder can never be closed in OS X, the Finder icon will always have a black dot underneath it. Hopefully, as you begin to learn more about your Mac, it’ll become easier to use. Enjoy!
