开启成功，重启生效
首次重启开机logo会变得巨大，之后就不会了

开启 1080p，模拟使用 2560x1440 分辨率

原因如下：

你要先搞懂 HIDPI 是什么，它使用横纵 2 个物理像素也就是 4 个物理像素来显示 1 个像素区域，结果就是图像的细节得到翻倍、更清晰、边缘更平滑。

拿 13 寸的 MacBook Pro 举例，它的屏幕物理分辨率是 2560 x 1600，所以原生的 HIDPI 分辨率就是 1280x800。更高的一档 1440x900 hidpi 缩放分辨率，则是虚拟出一个 2880x1800 的分辨率，再进行软缩放输入。所以你能发现苹果的电脑总是有很高的分辨率。

好了，既然你的屏幕是 1080p，本身就没有那么多像素去合成 HIDPI，如果以原生的显示计算，你这屏幕的 1080p 分辨率应该是 960x540，这么低的分辨率你是没法用的，所以就有了这个脚本。

这个脚本的功能是虚拟出比你的屏幕物理分辨率更高的假分辨率，也就是你看到的 3360 x 1888，这样你就可以使用 1680 x 944 hidpi 这个缩放分辨率了。

如果你要开启 1080p 的 HIDPI 分辨率，就虚拟一个 3840 x 2160 的假分辨率，然后 MacOS 会使用 4 个像素来显示 1 个像素区域，也就是和你物理分辨率一样的 1080p 分辨率，开不开启看起来没任何区别，最大的效果就是显卡压力增大系统变卡、截图可以得到高分辨率图像。

所以说，试图开启和物理分辨率一样的 HIDPI 分辨率，是愚蠢的行为。

因为有很多人问过这个问题，所以我详细的回复一下。
