Do you still use screen savers on your personal computer? Screen savers aren’t as as necessary as they once were, but if you like the look–or use them for useful things like a “word of the day”–macOS still has quite a few you can set up and configure.

您还在个人计算机上使用屏幕保护程序吗？ 屏幕保护程序不再像以前那样需要，但如果您喜欢它的外观，或者将它们用于诸如“每日一词”之类的有用事情，那么macOS仍然可以设置和配置很多。

Screen savers were originally designed to prevent burn-in of images on older CRT and plasma displays. By animating your screen, a screen saver ensures that static images don’t burn patterns into your display.

屏幕保护程序最初旨在防止旧的CRT和等离子显示器上出现图像残留。 通过对屏幕进行动画处理，屏幕保护程序可确保静态图像不会在您的显示器中烧入图案。

Nowadays, this burn-in problem isn’t a problem for LCD displays, so screen savers have kind of fallen by the wayside. Still, they can be pretty cool and are a nice distraction, which is why they still come on your computer, be it a Mac, a Linux machine, or a Windows PC.

如今，这种老化问题对于LCD显示器而言已不是问题，因此屏幕保护程序已经被淘汰了。 尽管如此，它们仍然可以很酷，而且很吸引人，这就是为什么它们仍然出现在您的计算机上的原因，无论是Mac，Linux机器还是Windows PC 。

在macOS上**和配置屏幕保护程序 (Activating and Configuring Screen Savers on macOS)

Setting up a screen saver on your Mac is pretty easy, whether it’s one of the many that are included with the system, or one you downloaded and installed. To get started, first open the System Preferences and then click “Desktop & Screen Saver”.

在Mac上设置屏幕保护程序非常容易，无论它是系统附带的众多屏幕保护程序之一，还是您下载并安装的屏幕保护程序之一。 首先，请先打开“系统偏好设置”，然后单击“桌面和屏幕保护程序”。

On the Screen Saver panel, there’s a left pane where you can choose your screen saver and a right pane where you can see a small preview.

在“屏幕保护程序”面板上，有一个左窗格，您可以在其中选择您的屏幕保护程序，在右窗格中，您可以看到一个小的预览。

The top portion of the left pane is heavy with photo album screen savers, while the bottom is where you will find more traditional graphical and text-based types of screen savers.

左窗格的顶部是相册屏幕保护程序的沉重部分，而底部是您可以在其中找到更多传统图形和基于文本类型的屏幕保护程序的地方。

For the photo album variety, you can choose a source such as predefined collections, recent photo events, or you can choose a custom folder or photo library.

对于相册种类，您可以选择来源，例如预定义的收藏集，最近的照片事件，或者可以选择自定义文件夹或照片库。

Below the screen saver choices are durations you can choose for when your screen saver activates. You can set anywhere from “Never” (off) up to one hour. Also available is the option to display the clock over the top of your screen saver so that you can keep track of the time even while your desktop is hidden.

屏幕保护程序选项下方是您可以选择**屏幕保护程序的持续时间。 您可以在“从不”(关闭)到一小时之间进行设置。 还可以选择在屏幕保护程序的顶部显示时钟，以便即使隐藏桌面也可以跟踪时间。

Next, check out the hot corners options. Here, each menu is a corner you can set up to perform a specific action when you drag the mouse into it. So, you can set it up to start (or disable) the screen saver, launch Mission Control, the Notification Center, and so on.

接下来，查看热点选项。 在这里，每个菜单都是一个角，您可以将其设置为在将鼠标拖动到其中时执行特定操作。 因此，您可以将其设置为启动(或禁用)屏幕保护程序，启动任务控制，通知中心等。

Don’t forget to check out a screen saver’s options. Not all will have options, but many will, whether it’s the ability to change the text output, colors, speed, and so on.

不要忘记签出屏幕保护程序的选项。 并非所有人都有选项，但无论是更改文本输出，颜色，速度等的功能，还是都有很多选项。

You’re not limited to the screen savers that only come on your Mac however, there are still plenty of options out there on the Internet.

您不仅限于Mac上仅提供的屏幕保护程序，但是Internet上仍然有很多选择。

在Mac上安装新的屏幕保护程序 (Installing New Screen Savers on Your Mac)

You might be tired of the ones that come with your computer, so set your destination for Google and search for some new ones. You can also check out Screensavers Planet or this curated list at GitHub for some awesome ones. To install a screen saver on your Mac, first download it, then open the DMG (or whatever container file it comes in) and then drag it to one of two folders.

您可能已经厌倦了计算机随附的计算机，因此请为Google设置目的地并搜索一些新计算机。 您也可以在GitHub上查看Screensavers Planet或此精选列表，以获得一些很棒的列表。 要在Mac上安装屏幕保护程序，请先下载它，然后打开DMG(或其附带的任何容器文件)，然后将其拖动到两个文件夹之一。

To install the screen saver on your profile only (doesn’t require administrator privileges), drag the file to the Screen Savers folder in your Home folder.

要在只有你的个人资料设置屏幕保护程序(不需要管理员权限)，拖动文件到屏幕保护程序中的个人文件夹文件夹。

If you want to install the screen saver for your entire system, meaning that other users can set it on their profiles, then you will need administrator rights.

如果要为整个系统安装屏幕保护程序，这意味着其他用户可以在其配置文件上进行设置，那么您将需要管理员权限。

Drag the screen saver file to /Library/Screen Savers.

将屏幕保护程序文件拖到/ Library / Screen Savers 。

Then click “Authenticate” and enter your credentials (usually just your password).

然后单击“身份验证”并输入您的凭据(通常只是您的密码)。

Now, either way, you can select your new screen saver and it will appear on your computer after the set duration, or you move the mouse to a hot corner.

现在，无论哪种方式，您都可以选择新的屏幕保护程序，它会在设置的持续时间后显示在您的计算机上，或者将鼠标移到某个热角。

Don’t forget, you can also set your Mac screen saver to run as your desktop background with a cool little command line hack.

别忘了，您还可以通过一个很酷的命令行小技巧，将Mac屏幕保护程序设置为作为桌面背景运行。

That about covers it. Screen savers are a pretty easy part of your Mac to grasp, but it’s still nice to know all the features and options that come with them.

到此为止。 屏幕保护程序是Mac上非常容易掌握的一部分，但是很高兴知道它们附带的所有功能和选项。
