视网膜屏幕
Straining to see stuff on your MacBook’s screen? If you’ve got a high-resolution Retina display (like the MacBook Pro or the 12″ MacBook have) it’s easy to adjust everything—text, icons, buttons, etc—on the display to be bigger.
想要在MacBook的屏幕上看东西吗？ 如果您有高分辨率的Retina显示屏(例如MacBook Pro或12英寸MacBook)，则可以轻松调整显示屏上的所有内容(文本，图标，按钮等)，使其更大。
For decades, people with vision problems have adjusted their system resolution to make things like text and interface elements bigger. This is a terrible idea, because it distorts basically everything on your screen. If your Mac offers a Retina display, the System Preferences offers a better way.
几十年来，有视力障碍的人们已经调整了系统分辨率，以使诸如文本和界面元素之类的东西变大。 这是一个糟糕的主意 ，因为它基本上扭曲了屏幕上的所有内容。 如果您的Mac提供Retina显示屏，则系统偏好设置提供了更好的方法。
Instead of changing the system’s resolution, macOS can scale things like interface elements and text, allowing photos and other graphics to still take full advantage of the display’s native resolution. It’s somewhat akin to the DPI scaling on Windows 10, but a lot less confusing.
macOS无需更改系统的分辨率，而是可以缩放界面元素和文本等内容，从而使照片和其他图形仍可以充分利用显示器的原始分辨率。 它在某种程度上类似于Windows 10上的DPI缩放 ，但不那么令人困惑。
如何调整Mac的显示比例 (How to Adjust Your Mac’s Display Scaling)
To explore these settings, head to System Preferences > Display.
要浏览这些设置，请转到系统偏好设置>显示。
Under “Resolution,” check the “Scaled” option. You’ll be presented with four to five choices, depending on the size of your screen.
在“分辨率”下，选中“缩放”选项。 根据屏幕的大小，您会看到四到五个选择。
I’m using a 13-inch MacBook Pro with a resolution of 2560 by 1600 pixels. I’m presented with four options, all of which “look like” a hypothetical resolution on a previous-generation Mac. The default, for example, “looks like” 1440 by 900 pixels, which you can see by hovering your mouse pointer over the option.
我正在使用分辨率为2560 x 1600像素的13英寸MacBook Pro。 为我提供了四个选项，所有这些选项都“看起来”像上一代Mac上的假设分辨率。 例如，默认值“看起来像” 1440 x 900像素，您可以通过将鼠标指针悬停在该选项上来查看。
The two options below the default “look like” 1280 by 800 and 1024 by 640, as I work my way down. The option above the default “looks like” 1680 by 1050.
当我向下工作时，默认“看起来像” 1280 x 800和1024 x 640下面的两个选项。 默认值上方的选项“看起来像”是1680 x 1050。
These numbers are somewhat arbitrary, in that they are related to how previous-generation Macs looked at particular resolutions. The precise choices offered will vary depending on your specific Mac model. And to be clear, your system resolution doesn’t actually change if you choose a different setting: just the scaling of things like text and interface elements will change. The result is similar to changing resolution on older Macs, but without the visual distortions.
这些数字多少有些随意，因为它们与上一代Mac电脑如何看待特定分辨率有关。 提供的精确选择将根据您的特定Mac型号而有所不同。 需要明确的是，如果您选择其他设置，您的系统分辨率实际上不会改变：只有文本和界面元素之类的缩放比例会改变。 结果类似于在较旧的Mac上更改分辨率，但没有视觉失真。
Are you wondering what this looks like? Well, here’s my desktop set to the default setting, which “looks like” 1440 by 900 pixels.
您想知道这是什么样吗？ 好吧，这是我的桌面设置为默认设置，“看起来”是1440 x 900像素。
And here it is when I choose the “More Space” option, which “looks like” 1680 by 1050 pixels:
这是当我选择“更多空间”选项时，它“看起来像” 1680 x 1050像素：
As you can see, the browser window takes up a lot less space on my desktop now, and the menu bar looks quite a bit smaller. If you have good eyesight, this setting can make your Mac’s display feel quite a bit bigger, allowing you to have more things on the screen at once.
如您所见，浏览器窗口现在占用的桌面空间要少得多，菜单栏看起来要小得多。 如果您的视力良好，则此设置可使Mac的显示感觉更大，从而使您可以一次在屏幕上显示更多内容。
Going the other way, here’s one size smaller than the default, which “looks like” 1280 by 800:
换种方式，这比默认尺寸小一个，“默认尺寸”为1280 x 800：
Everything is a little bit bigger, and the browser window (which I haven’t resized) now takes up most of the screen. Let’s go one step further, making the display “look like” 1024 by 640 pixels:
一切都变大了，浏览器窗口(我尚未调整大小)现在占据了大部分屏幕。 让我们更进一步，使显示“看起来”为1024 x 640像素：
The browser now takes up the entire screen, and the menu bar is now freaking huge. I could never work like this, but someone with much worse eyes than me could benefit from it.
现在，浏览器占据了整个屏幕，菜单栏也变得异常庞大。 我永远不能这样工作，但是比我眼睛差很多的人可以从中受益。
Again, none of these settings actually changes the resolution of the display: all they do is change the relative sizes of things.
同样，这些设置实际上都不会更改显示的分辨率：它们所做的只是更改事物的相对大小。
外接显示器的注意事项 (A Note on External Monitors)
I use an external monitor at my desk—one I’ve had for years. When I head to the Displays panel in System Preferences with that display connected, macOS opens two windows: one for my built-in display, and another for my external display. In my case the external display is not high-density, so I can control the resolution.
我在办公桌上使用一台外接显示器-我已经使用了多年。 当我在连接该显示器的情况下进入“系统偏好设置”中的“显示器”面板时，macOS将打开两个窗口：一个窗口用于内置显示器，另一个窗口用于外部显示器。 就我而言，外部显示器不是高密度的，因此我可以控制分辨率。
So what happens when I drag a window from a high-density display to a low-density one? The window moves, seamlessly, making the adjustment in scaling as you drag it over. This is true regardless of which scaling option you’ve chosen for your high-density display. It seems like a small thing, but trust me: this is a marvel of engineering.
那么，当我将一个窗口从高密度显示器拖动到低密度显示器时会发生什么？ 窗口无缝移动，在拖动时缩放比例进行调整。 无论您为高密度显示器选择了哪种缩放选项，这都是正确的。 这似乎是一件小事，但请相信我：这是工程学的奇迹。
It’s also worth noting that your Mac will “remember” what kind of scaling you want on your Retina display while a particular external display is connected, and when no external display is connected. It’s a subtle thing, but can be very helpful.
还值得注意的是，当连接了特定的外接显示器时，以及未连接外接显示器时，Mac会“记住”您想要在Retina显示器上缩放的比例。 这是一个微妙的事情，但可能会很有帮助。
For example, I like the scaling on my MacBook Pro’s display to be set to “More Space” when it’s not connected to any external display, so that I have as much room to work with as possible. When I’m at my desk, however, I stand a little further back from the display. This, combined with the lower resolution of my external, means I’d like the the Retina display scaled up a little when the external is connected.
例如，当不连接任何外接显示器时，我喜欢将MacBook Pro显示器上的缩放比例设置为“更多空间”，以便我有尽可能多的空间来使用。 但是，当我坐在办公桌前时，我离显示器稍远。 再加上外部设备的较低分辨率，这意味着我希望在连接外部设备时将Retina显示屏放大一点。
To achieve this, I set the scaling to “More space” while the display was not connected. Then, I connected the display and set the scaling on my built-in display to “Default.” Now the scaling switches automatically when I connect or disconnect the external display.
为此，我在未连接显示器时将缩放比例设置为“更多空间”。 然后，我连接了显示器，并将内置显示器的缩放比例设置为“默认”。 现在，当我连接或断开外接显示器时，缩放比例会自动切换。
需要更多选择吗？ 检出视网膜显示菜单 (Want More Choices? Check Out Retina Display Menu)
Five scaling choices isn’t very many, though in my opinion the range offered will probably cover most use cases. If you want to set things more precisely, however, you should download Retina Display Menu, a free menu bar application that lets you set the relative resolution to whatever you want on your Retina display. To install, you’ll have to work around Gatekeeper by right-clicking, then clicking “Open.” Once it’s up and running you’ll see a menu bar icon.
虽然我认为提供的范围可能涵盖大多数用例，但五个缩放选择不是很多。 但是，如果您想更精确地进行设置，则应下载Retina Display Menu ，这是一个免费的菜单栏应用程序，可让您将相对分辨率设置为Retina显示屏上所需的任何分辨率。 要安装，您必须通过右键单击然后单击“打开”来解决Gatekeeper 。 一旦启动并运行，您将看到一个菜单栏图标。
Click this and you can choose any resolution—the best matches for your display are marked with a lightning bolt. You can get some truly ridiculous settings doing this—for example, here’s how my MacBook Pro looks at full resolution with no scaling:
单击此按钮，您可以选择任何分辨率-显示屏上最匹配的部分用闪电标记。 您可以进行一些真正荒谬的设置，例如，这是我的MacBook Pro在不缩放的情况下以全分辨率显示的样子：
The browser window here is the same size as before, for reference, and the menu bar can hardly be seen. This isn’t practical at all—text is barely readable—but if nothing else it’s a good object lesson as to why Retina displays need scaling in the first place.
仅供参考，此处的浏览器窗口大小与以前相同，几乎看不到菜单栏。 这根本不切实际-文本几乎不可读-但是如果没有其他选择，那么这是一个很好的对象课程，说明了为什么视网膜显示器首先需要缩放。
For most people, the default scaling options will work. But that doesn’t mean playing with an application like this isn’t fun, so give it a shot.
对于大多数人来说，默认缩放比例选项将起作用。 但这并不意味着使用这种应用程序并不有趣，因此请尝试一下。
