Running OSX 10.8.5 Mountain Lion. Just updated to Safari 6.1 and the Java update via the App store updates. Since then neither my Mac Pro (2009) or iMac will play YouTube videos in Safari. I get a message that says "An Error Occoured" Strangley, the commercials will sometimes play at the begining of the video, but not the actual video I want to view.

 

In addition, both are seeing very high CPU useage (167%) due to Java. This only happens after launching Safari.

 

I restarted several times, ran permmissions and disk repair, and shut off Safari extensions.

 

YouTube play fine in Chrome!

 

Any ideas are welcome.

    Open System Preferences > Flash Player then select the Advanced tab.

     

    Click Delete All under Browsing Data and Settings

     

     

     

    Quit and relaunch Safari, try a video.

    Appreciate the tip but it didn't make a differnce. Tried it twice.

    Empty Caches and try troubleshooting Safari extensions ...

     

     

    From your Safari menu bar click Safari > Preferences then select the Advanced tab.

     

    Select:  Show Develop menu in menu bar

     

    Now click Develop from the menu bar. From the drop down menu click Empty Caches.

     

     

    Quit and relaunch Safari. If you still have problems, try troubleshooting Safari extensions.

     

    From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test. I

     

    If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.

    Java is irrelevant to YouTube. You should disable it.

     

    From the Safari menu bar, select

            

    Safari Preferences Extensions

         

    Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.

     

    If you wish, you may be able to salvage the errant extension by uninstalling and reinstalling it. Its settings will revert to their defaults. If the extension still causes a problem, remove it permanently or refer to its developer for support.

    I tried shutting off extensions earlier with no luck.

     

    I emptied Safari Chache with no luck. Also deleted Cache.db from Library-Caches-com.apple.safari

     

    Still no luck.

     

    Reinstalled Flash for yucks. Nothing there either.

    Maybe an incompatible Safari 6.1 plug-in ...


     

    Safari > Preferences > Security

     

    Deselect:  Allow all other plug-ins. Quit and relaunch Safari to test.

     

    If that made a difference, instructions for troubleshooting plugins here.

    Please read this whole message before doing anything.

     

    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.

     

    Step 1

     

    The purpose of this step is to determine whether the problem is localized to your user account.

     

    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”

     

    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

     

    Test while logged in as Guest. Same problem?

     

    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

     

    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.

     

    Step 2

     

    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, or by corruption of certain system caches.

     

    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.

     

    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models.  The next normal boot may also be somewhat slow.

     

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

     

    Test while in safe mode. Same problem?

     

    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

    This makes no sense. I have four user accounts including the guest.

     

    YouTube (YT) plays on the guest account and on User account 2 but not on User 3 or my Admin User (1).

     

    The other user accounts are never actaully used, they were stricktly set up for alternate access in case anything ever went wrong.

     

    YouTube will not play in Safe Boot mode, which really surprises me. 

     

    On the accounts where YT will not play, the player within YT has a warning that Acrobat is not installed. I reinstalled over the existing app and that didn't work, so I unistalled, restart, reinstalled, restart and still nothing. I emptied Safari chache every time.

     

    I also tried Carolyn's suggestion, Deselect:  Allow all other plug-ins.

     

    Thanks for your patience.

    Here are two eaxamples. Note that in the player there have been a few occassions when it stated that a acrobat was missing. Unfirtunaely I didn't get a screen shot that time. Other are included.

     

    Note, these are two images on one file. The red banner comes up when loading the page. The black box displays after selecting a video.

    That message refers to Flash, not Acrobat. Are plugins enabled in Safari's preferences?

  • 12. Re: Safari 6.1 won't play YouTube Videos, Java screaming
    Daniel Gould1 Level 1 Level 1 (15 points)

    Brain ****, yes Adobe Flash. (I'm a heavy Acrobat user and it just rolls off the tongue)  Yes, plugins enabled in Safari's preferences.

     

    Pardon my past typos.

    If you're sure you've installed the latest version of Flash, take each of the following steps that you haven't already tried. After each step, relaunch Safari and test. For a "missing plug-in" error, start with Step 5.

    1. If you're only having trouble with YouTube videos, sign in to your YouTube account and load this page. You may see a link with the text "Leave the HTML5 Trial." If so, click that link.

    2. If you're getting a "blocked plug-in" error, then from the menu bar select

     

     ▹ System Preferences… ▹ Flash Player Advanced

    and click Check Now. Quit and relaunch your browser.

     

    3. Triple-click anywhere in the line below on this page to select it:

    /Library/Internet Plug-Ins
      
    Right-click or control-click the highlighted text and select
      
    Services ▹ Open
      
    from the contextual menu.* A folder should open. Delete the following item, or anything with a similar name, if present:
    • Flash Player (failing).plugin  
    You may be prompted for your login password.

    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select

    Go Go to Folder...

    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

      
    4. Re-download and reinstall Flash. Download it from this page:
       
       
    Never download a Flash update from anywhere else.
        
    5. If you get a "missing plug-in" error, select
     
    Safari Preferences... Security
      
    from the Safari menu bar and check the box marked Enable plug-ins.

     

    6. Select

    Safari Preferences... Extensions

    from the Safari menu bar. If any extensions are installed, disable them.

    7. In the Safari preference window, select

    Privacy Remove All Website Data

    Close the window. Then select

     ▹ System Preferences… ▹ Flash Player Advanced

    and click Delete All. Close the preference pane.

    Daniel Gould1 Level 1 Level 1 (15 points)

    Success!

     

    Here is what solved the issue on both machines:

     

    In the Safari preference window, select Privacy ▹ Remove All Website Data. Close the window.

    Then select  ▹ System Preferences… ▹ Flash Player ▹ Advanced and click Delete All. Close the preference pane.

     

    The only item I had yet to attempt was Remove All Website Data. I'm guessing that was the key.

     

    I'd love to know what the actual conflict was.

     

    Now I need to figure out why Java is running so high. I can't even force quit it in Activity Monitor.

     

    Thankls a million.
