Downloading a movie from YouTube is easier than operating a microwave. You don’t even need a YouTube account! With just a internet browser (Safari in this case) and a few clicks you can watch your favorite, legal clips from your hard drive.
However, before you start downloading, please review U.S. fair use laws to make sure that you do not break the law.
Now let’s get started!
Step 1: After opening Safari, go to the window tab and select activity.
This should bring up an activity box with a list of every task that the browser has loaded.
Step 2: Go to YouTube and open the page for the video you wish to download. As it is loading, browse the activity box for the specific video task. It will most likely be the largest file.
Now simply double-click on the file and it will automatically download to your desktop in a flash video format (.flv).
Good luck and remember to stay legal!
