    Launch Google Chrome. This method involves using Google's browser, which requires you to run Mac OSX 10.6 or later. This method involves copy and pasting the video from the cache that Chrome automatically keeps track of, so it won't work in Safari, Firefox, Internet Explorer, or other browsers.

    Find the video file. This is the tricky part. The information isn't named in a convenient way, because it's the raw data, so start by scrolling from the bottom of the list and looking closely for a file of the appropriate size. A video file will be sizable, somewhere between 20-40MB for an HD video, depending on the length and quality. When you've located your video file, right click, copy the file and paste it onto your desktop.
    • Check the size of the video in YouTube under the gear icon in the lower right corner of the video to give you some indication of the size. A 20 minute video in HD720p, for example, will be sizable. As you're scrolling, you can eliminate everything under 10MB very quickly until you find the file.

    Rename the extension. To open the file in Quicktime or other video players, you'll need to rename the extension by clicking on the file name and adding .mp4 to the end. A window will pop up, asking if you want to add the extension. Click yes and rename the video something convenient so you'll recognize it. Then double-click on the file to play it.
