macos mojave_如何修复macOS Mojave上的模糊字体（使用亚像素抗锯齿）

macos mojave

Apple’s macOS Mojave disables subpixel antialiasing, also known as font smoothing, by default. On a MacBook Air or a desktop Mac hooked up to a non-Retina display, upgrading will make your fonts look worse.

苹果的macOS Mojave默认情况下禁用子像素抗锯齿，也称为字体平滑。在连接到非Retina显示器的MacBook Air或台式Mac上，升级将使字体看起来更糟。

Update: We’ve found a better method that will actually re-enable subpixel antialiasing rather than just relying on font smoothing. Open a Terminal and run the following command:

更新：我们发现了一种更好的方法，该方法实际上将重新启用亚像素抗锯齿功能，而不仅仅是依靠字体平滑。打开终端并运行以下命令：

defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO

这是区别 (Here’s the Difference)

Subpixel antialiasing is a trick designed to make fonts look better on lower-resolution displays. Without this feature enabled by default, macOS Mojave makes text look thinner and more blurry on non-Retina displays.

亚像素抗锯齿是一种技巧，旨在使字体在较低分辨率的显示器上看起来更好。如果没有默认启用此功能，则macOS Mojave会使非Retina显示屏上的文本看起来更细，更模糊。

(As some eagle-eyed readers have noticed, the below trick doesn’t technically enable subpixel antialiasing. However, this does increase font weight, which makes fonts look less jagged and all-around better on the MacBook Air and other low-resolution displays.)

(正如一些老鹰眼的读者所注意到的那样，以下技巧从技术上讲并未启用亚像素抗锯齿。但是，这确实增加了字体粗细，这使得字体在MacBook Air和其他低分辨率显示器上看起来不那么锯齿，并且全方位更好。 )

While subpixel font smoothing is disabled by default, you can re-enable it with a terminal command. There are four possible settings: 0 (disabled), 1 (light smoothing), 2 (medium smoothing), and 3 (heavy smoothing).

默认情况下，禁用子像素字体平滑功能时，可以使用终端命令重新启用它。共有四种可能的设置：0(禁用)，1(轻度平滑)，2(中度平滑)和3(重度平滑)。

Here’s what they look like:

它们是这样的：

We don’t recommend enabling subpixel antialiasing if you have Mac with a Retina display. Fonts should look nice and readable on a Retina display even without subpixel antialiasing. But, if you have a non-Retina display, we recommend re-enabling this feature.

如果您的Mac配备Retina显示器，我们不建议启用亚像素抗锯齿功能。即使没有亚像素抗锯齿，字体也应该在Retina显示屏上看起来不错并且可读。但是，如果您使用的不是Retina显示屏，建议您重新启用此功能。

如何启用亚像素抗锯齿 (How to Enable Subpixel Antialiasing)

You must run a terminal command to change your subpixel antialiasing settings. To open a Terminal window, press Command+Space to open Spotlight search, type “Terminal,” and press Enter. You can also open a Finder window and head to Applications > Utilities > Terminal.

您必须运行终端命令来更改子像素抗锯齿设置。要打开终端窗口，请按Command + Space打开Spotlight搜索，键入“ Terminal”，然后按Enter。您也可以打开Finder窗口并转到“应用程序”>“实用程序”>“终端”。

Copy and paste one of the following commands into the Terminal window and press Enter.

将以下命令之一复制并粘贴到“终端”窗口中，然后按Enter。

Light font smoothing (1):

轻字体平滑(1)：

defaults -currentHost write -globalDomain AppleFontSmoothing -int 1

Medium font smoothing (2):

中字体平滑处理(2)：

defaults -currentHost write -globalDomain AppleFontSmoothing -int 2

Heavy font smoothing (3):

重字体平滑处理(3)：

defaults -currentHost write -globalDomain AppleFontSmoothing -int 3

No font smoothing (0):

没有字体平滑处理(0)：

defaults -currentHost write -globalDomain AppleFontSmoothing -int 0
