如何在Mac上禁用屏幕快照预览缩略图
When you take a screenshot on a Mac, macOS usually displays a tiny thumbnail of the screenshot in the lower-right corner of the screen for a few moments before saving the image. If you find this annoying, it’s easy to turn off. Here’s how.
在Mac上拍摄屏幕快照时 ，macOS通常会在屏幕右下角显示屏幕快照的缩略图一会儿，然后再保存图像。 如果您觉得这很烦，很容易将其关闭。 这是如何做。
为什么还要有缩略图？ (Why Even Have a Thumbnail?)
You might be wondering: why show the thumbnail at all? As far as we can tell, Apple decided this would be the best way to trigger macOS’s built-in screenshot editing feature, which has been present since Mac OS X 10.14 Mojave.
您可能想知道：为什么不显示缩略图？ 据我们所知，Apple认为这将是触发macOS内置屏幕截图编辑功能的最佳方法，该功能自Mac OS X 10.14 Mojave开始出现。
If you click on the screenshot thumbnail that appears, the screenshot opens in a special editor that allows you to crop the image or annotate it with drawings, shapes, or text before it gets saved to disk. You also have a chance to discard the image if you don’t like it.
如果单击出现的屏幕快照缩略图，则屏幕快照将在特殊的编辑器中打开，该编辑器允许您在将图像保存到磁盘之前裁剪图像或使用绘图，形状或文本对其进行注释。 如果您不喜欢它，也可以将其丢弃。
But that’s a lot of extra capability for people who just want to quickly take a screenshot. Luckily, Apple makes it easy to disable this feature.
但这对于只想快速截图的人来说是很多额外的功能。 幸运的是，Apple可以轻松禁用此功能。
