    Also the memory usage in Lion seems to be extremley high. Is this the same for everyone else?

  • prajnaji Level 1 (20 points)

    Mine has too.


    Sometimes my processor just goes off the charts as well.


    I have also found that the finder preview feature on h264 quicktimes won't run in real time. Stutters really bad. Ugh. Huge issue for me currently.

  • *nickMcC* Level 1 (0 points)

    I think I have found a work around. With two ways or both


    1. Go to System Preferences-> Energy Saver -> Switch it from Battery Life to High performance.


    This turns off the GPU switching which for me is a NVIDIA 9400m to 9600m gt . So basically now the battery will drain tons faster but it is stable. I got through three episodes of Breaking Bad lastnight wih Zero crashes.


    2. Get GfxStatus program @

              This allows you to set which GPU is running and to allow it to switch or not. So a good test is to leave the Battery Life on and see if the switch and crash happen at the same or close times.


    FYI this does not help with the memory consumption, that is a LION problem that may never be fixed. Maybe it is efficent maybe its not. I do know Virtualbox ***** on this compared to SL.


    Good luck!

    Leonardo, something else is wrong with your setup. it could be your internet service provider. have you tried clearing your cache?

  • leonardo87 Level 1 (0 points)

    yes man, i've tried everything... =/ nothing with the three browsers.. my mac ox is 10.7.2.

  • TheSmokeMonster Level 4 (3,230 points)

    can you give me more information of what is happening and what you are seeing and what you've already done?

  • BaronIstefan Level 1 (5 points)

    Hi, I have the exact same issue.  I was watching Netflix and it asked me to upgrade from v4 to v5 of Silverlight.  Now nothing works in Silverlight and each browser just shows that the plugin has crashed.  I have deleted the files for Silverlight on several occassions, deleted caches, restarted the computer several times and it still will not work.  Reinstalling v4 Works fine, but Netflix will not let me watch using the older version of the plugin.


    I have a Mac Pro (Server) 2009 with 1 Quad Core 2.66 GHz Xeon, 8 GB 1033 DDR3 RAM, 2 Monitors, 2 NVidia GT 120 graphic cards running OSX 10.7.2.

    Hey Baron! please file this with apple

  • claas kuhnen Level 1 (0 points)

    Hi there


    I also had the issue that Netflix loaded the Silverlight plug-in showed the image but did simply not play the movie.


    I followed MS advice to uninstall SL manually by removing it from Library/Internet Plug-ins

    and then reinstalling.


    However the error never went away.


    I tried to install SL 3 and it told me a newer version was present which gave me the impression SL 5 was not 100% removed. Searching the web a but I found this thread:



    Remove all those files and it will propably work now.

    I installed SL3 which worked after a restart then Netflix wanted to update to SL5 which I did and all runs smooth again.


    MS great job - what a garbage.

  • claas kuhnen Level 1 (0 points)

    OMG MS or Apple must be kidding me.


    I just realized that when under OS X Lion I switch from speaker to USB headphone Netflix/Silverlight stops playing the movie. The moment I switch back to speakers it runs.


    This is pathetic and I start getting the feeling this might be an issue with Apple as their USB AUdio drivers also do not work with Skype anymore.

  • claas kuhnen Level 1 (0 points)



    To make Skype run via USB Audio on Lion you could use the MIDI input and change the frequency to 16 KHz.

    However this produces an issue with Silverlight.


    I switched back to 32 KHz and SL runs fine again.



  • jmpsfs Level 1 (10 points)

    Thanks for this. I spent an hour on the phone with Apple Customer Care discussing the Silverlight problem, and the tech finally gave up and told me to contact Microsoft.


    I switched the audio output from my Logitech USB headset to the internal speakers and Netflix came back to life.


    Now I guess I'll get back on the phone with Apple to see how to reconfigure the headset so it will work with video. Another PITA problem, but at least the video is moving again.

    This has been tested and confirmed solution on 10.7.3


    If you are having problems with Silverlight staying in full screen on your secondary display then something bad has happened to your preference files. Anyway long story short the fastest and easiest way is to remove Silverlight and ALL the preference files and reinstall it. If everything has gone as it should, at that point you will be prompted if you want to permit Silverlight to stay in full screen mode. You should do so and after that your problems will be solved. As to the high RAM usage and CPU load while playing Netflix in high def there really isn't anything you can do. Silverlight does suport hardware acceleration, however that is only in Windows 7 SP1 + and only in IE9. As to the amount of RAM, Silverlight on OS X is 32 bit (even version 5) and unfortunatelly that means loading additional libraries in Safari and RAM usage does go up. That said, on a MBP mid 2010 with a 2.4 Ghz Core i5 CPU, it runs without a hitch and does not really affect the performance of the other Applications. Silverlight does however use about 50% of one of the cores so on an older machine, that would be a serious.


    Ok here's what you need to delete


    • /Library/Internet Plug-Ins/Silverlight.plugin
    • /Library/Receipts/Silverlight.pkg
    • /Library/Receipts/Silverlight_W2_MIX.pkg
    • /Library/Internet Plug-Ins/WPFe.plugin
    • /Library/Receipts/WPFe.pkg
    • "/Applications/Microsoft"


    You can do this by using sudo rm -rf <one of the above> but you probably shouldn't since you can easily delete something by mistake and the OS will not even give you a warning, or you can use Finder to navigate to the locations and delete the files by moving to Trash. You will be asked for a password (your own) and also, since it's Lion, you will have to use Cmd+Shift+G and then paste the location.


    One last thing, some of the above might not exist which is alright. Some were removed in latter versions of Silverlight so don't worry.


    Oh and Microsoft suggests that Silverlight does not work in Chrome on OS X ... that is false! You might however, have flaky performance in the beta or developer versions so stick with stable.

  • Unknown Citizen Level 1 (15 points)

    I haven't had any issues running Silverlight, it's just frustrating that all the fans turn on once I try to run Netflix using the silverlight plugin.  The same is true with flash of course.  I'm just waiting for web developers to adopt HTML5 already and ditch these plugins that tax the system so heavily.
