Even MacRumors has confirmed that users are facing problems with watching YouTube on Mac's Safari browser. However, it has also stated that it is a problem only with a few of the users. Many users on the support forum of Apple actually tried different methods to resolve problems of watching YouTube videos on Safari. The types of troubleshooting that people have tried include resetting the PRAM, clearing caches and cookies, and rebooting the system. However, there is only one temporary fix that has been found for the issue. It is:

  • Go to Develop. Click on User Agent and check Google Chrome option there

However, this is a temporary solution and once the browser is closed, the fix is gone! So, the next time you open the browser, the issue is again there. In case you are facing problems in watching YouTube videos in Safari, if you have Chrome and Firefor or any other Internet browser in your device, you can use that until you deal with the issue permanently.

Given below is a list of possible solutions that you can try to ensure that YouTube is running fine in Safari:

  • Turn off the YouTube5 extensions if you have downloaded the same. However, if you have extensions like YouTube Video downloader 1.1.4 and YouTube5 2.2.1 installed, just turning off the YouTube5 extension should do the trick. After switching it off, you can play the videos normally. It should work.
  • For some users downloading and installing the 32-bit OS works. So, if possible, install the 32-bit OS for once until Apple comes out with a possible solution.
  • Another quick fix for the problem of YouTube not playing in Safari is that if you enable the "Develop" menu and change the user agent (change it to something other than the Safari 5.0.3 Mac). By doing this you can ensure that the YouTube would work fine. This should work permanently and the videos should play until there is any solution from the developers.

You can also compare your Mac's settings with that of the MacBook and make sure that the Mac's settings are same as that of the MacBook. Remove all unnecessary plugins from the system. You should be confident of the plugins that are unnecessarily there and need to be removed. Check the Installed Plug-ins list and find out information regarding the descriptions of the plug-ins. You should only remove the unwanted plugins. It is advised that you remove Flash and Shockwave plug-ins. In the description of the Flash Player, you should look for Shockwave Flash entry. Once you know the file name and find it out, you should remove that plug-in. Doing this will uninstall the plug in from the Safari browser.
