    Did not work for me. Hitting image with spacebar opens Photoshop or Acrobat, original source program. Not QuickLook. HELP!!!!!!!

  • I’ve been struggling, and struggling, and struggling with the tiny icons in the QL preview, for months, – and then I found your method, and the issue was solved in under 45 seconds. THANK YOU!!

    Simpler fix: relaunch the Finder. Cmd-opt-esc, select Finder, click relaunch. 100% success rate for me, and much less scary for most than messing around in the Activity Monitor.

    If that doesn’t work, sure, do this.
