How do I disable file previews in the Finder?

If the MacBook in your hand is an old-fashioned machine. It always feels like a card. So I'm going to find some way to get this old guy back to life. One of them is mentioned today.

We know that in the Finder's icon view, the display of the video, the picture will be a preview effect. This way your Mac may need to create and load thumbnails of these files from time to time, occupying a "labor force" that is not quite enough. In fact this thumbnail if you do not have to be, we have the opportunity to disable it. Here's how:

Open a new window in the Finder and switch to the icon view (press cmd+1). Then press CMD+J to open the Display Options panel (or right-click in the space and choose View Display Options), as shown in the figure above. Just put the "Show icon Preview" box in front of the boxes do not have a √. Alternatively, you can click the "Use as Default" button below to make this the default option. The display in your system may not be the same as the image above, but just find the same option to keep it out of check.

Just try it, do you feel your old Mac is a little bit faster?
