Reset Preview Icons

How to reset Macintosh Preview Icons

Every so often I find that my preview thumbnails through my Mac finder disappear. They don't disappear entirely, they just stop displaying the preview of the file and show only the generic jpeg icon. It's a fairly cumbersome problem, especially when the icon previews help determine which files I may want to use.

Fortunately, there's an easy fix for this and it's basically nondestructive.

  • Open to the Preferences folder of your home directory
  • (your home > library > preferences)
  • Delete com.apple.finder.plist
  • Right click on Finder icon in the dock and select Relaunch.

Note: This may not fix all icons. I find that it works best with EPS files and AI files.
