    This is my first iMac, so I'm not sure if the last issue of iMacs were plagued with problems at the beginning. if so, were these problems smoothed out with updates?

    some people say that we should chill out, but i argue on the contrary- this is a pathetic problem for a system to have, and i am considering returning this imac while i still can. i hope this isn't a sign of things to come. nobody is for sure rather it is hardware, software, SL or Adobe.

    the way i see it is if i bought a brand new Lexus and the cruise control didn't work, I wouldn't feel secure about what else in the car didn't work. what if the airbags don't deploy when i CRASH?

    Ok, after finding another retail copy of snow leopard #10b504 and installing it on the 27" iMac last night so far no slowdowns or spiking on the one cpu core. I ran Hulu videos as well as youtube content and all is well. I also notice that my xbench scores went from 184 to 199. I'm still using my wireless network with no hiccups so far. Again, this is for the last 12 hours or so. Your mileage may vary...

    This is a software problem - it happens - it always will - to EVERY company. I guarantee there are perfectly good Lexus cars out there with faulty cruise controls - it doesn't mean the car is a lemon!

    Yes there were issues with the first Intel iMacs - yes they were ironed out - no they weren't bad computers.

    Return a computer because Flash playback is choppy? For the people who find this unacceptable go a head and return the machines. I can wait a week for it to be fixed.

    Don't read too much into this....do you have any idea how complex the whole process of R&D is for something like this? Why are software companies releasing updates YEARS after initial release? These things are ALWAYS a work in progress and they always will be.

    BTW - I just spent 60 mins on the phone with MS because my Windows 7 Home Upgrade, that hey claim can be used to upgrade WinXP if you do a clean install, refused to recognize my product key. I had to essentially hack my registry to get this to install as intended. It's new, it happens, no big deal.

    fair enough, doc. so, what kind of time are we looking at for a fix based on your past experiences? i have mono right now, so i just want to sit on my couch and catch up on the office via hulu, but can't without restarting every 30 minutes.

    "

    I don't understand. Have you tried Frederico's solution (see his post above)? We have at least one confirmation that the problem can be easily fixed in this way.

    new problem. when i'm using my mac for an extended period of time (1 hour+), it is tending to slow down on me. everything from scrolling in my browser (both firefox and safari), to pause/play on itunes, to typing being displayed on delay (watching the letters show up on the screen a second after i typed them). call me impatient, but this is absolutely unacceptable.

    I'm not saying this isn't a BIG inconvenience for you - especially because you have mono and you're probably bored out of your mind. Apple is selling a lot of these machines, they're all under warrantee and so it's in Apples best interest to get on this fast.

    The last thing they want is to lose sales to something silly like lash playback. Give them a little time. The last thing you want is for them to rush something out and have it either not address the issue or cause more issues.

    P.S. - You're right in that this is annoying but it will be addressed. Apple is in tough spots ATM.....the economy *****, companies are going under left and right, and it's stock price is at an all time high. Always tough to stay on top...especially in these times.

    Or it's all a symptoms of the same problem

    If it makes you feel better I'm using my 27" under Windows 7 without any problems.

    These problems are always much more easily fixed when they're just software and not hardware.

    Hey Folks! I just ordered a new 27" "standard" iMac, though C2D, no extra options. Now I searched the web and found a lot of blogs discussing these strange graphic problems, while playing falsh-videos like on YT. As I am still waiting for my new iMac to arrive, I tried to reproduce these problems on my 15" MBP (late 2007) - recently updated to SnowLeo (two days ago).

    What I found out: CPU usage of up to 140% playing this YT video:

    http://www.youtube.com/watch?v=GnSbJIDOicM&feature=related

    I instantly tried to figure out more about the problem. I am not an IT pro (and that's why I bought a Mac in 2007 and it felt like heaven^^) But what I can say is that the effect of CPU usage that high is the same whilst playing this video on Safari as it is on Firefox. I have got both browsers installed, as I loved Firefox on my XP-notebook - before I found out about Safari.

    I must admit, I do not know whether my MBP acted like this prior to the update from Leo to SnowLeo. But I honestly think it got worse with SnowLeo. As soon as I start the video linked above, iStat states that both fans run up to 6'000 rpm and CPU temp flashes up to 75 degrees Celsius. GPU acts the same. The MBP fans really fight to cool down the PUs.

    Honestly, I am now afraid to watch YT videos of more than just a view minutes - I don't want to fry my CPU/GPU.

    Are there any known bugs about this problem and is there a fix already in process? Please let me know a.s.a.p. I am a HUGE Apple fan! I don't want to loose that faith in their products due to this problem. And: I am really concerned about that my soon-to-be-delivered 27" iMac could act up like the ones I read about in these blogs.

    Kind regards from Germany!

    One more information: my MBP connects to the internet via an Aiport Extreme base station. I mention this because some of the owners of affected 27" iMacs concluded that it might be a general problem of Airport. I wonder, as my logic (no IT geek here...^^) refuses to see any parallels between Airport and fully loaded flash videos. But anyways...

    This could be an important word AGAINST general problems with the new iMacs, but could proof a general non-compliance between Snow Leopard and flash videos. Strange enough: my MBP fans are still not down to their normal 2'000 rpm on idle - ten minutes after I watched the last flash video on YT! This cannot be healthy to my notebook, can it?!

    Rgds,
    Guido

    I mentioned in a previous post that Frederico has found an easy solution, who fixed (at least) two iMacs. Did you try it ? (read his post on this forum). The solution consists in just reseting the SMC and the PRAM:

    Good News?

    There is another thread on Apple-Support -Discussions, which is called 'iMac 27'' (Late 2009) Poor Performance and Flash Issues":

    http://discussions.apple.com/message.jspa?messageID=10495161#10495161

    This thread is displayed now with a green star, and the mention "This question is answered".

    I think some folks in this thread are mixing up Flash issues. The issue at hand here is the one that endgadget highlighted where on the 27 inch iMac a single you tube video playback would begin to shutter, skip and there was a corresponding CPU spike. If your Flash issue has different symptoms, then you have a different issue with Flash than this one.

    Using Flash with no issue will make the CPU work harder, so an increase in CPU usage is not completely unexpected and therefore, by itself, should not be seen as an issue.

    I think I have found the easiest workaround for this issue. When you start to get the single video play back shutter, skip and CPU spike. Just pull down the iMac AirPort menu and let it scan for networks. You will see the little spinning gear in the menu when this happens. No need to select any of the networks, just let it scan until the spinning gear goes away. Then click off the AirPort menu to close it. This seems to have the same "flushing" effect of the issue as the powering down and then on the iMac AirPort workaround, without the hassle of having to turn off your iMacs AirPort. There is also no need to close Safari or reload the video. Repeat this workaround when ever you encounter this issue.

    Please keep in mind the kind of Flash problem this workaround will help. It will not address all Flash issues. Just this one. I hope this help.

    If you feel you have the Flash issue I am speaking of and this workaround was not effective, please let the forum know. Thanks.

    Just for fun I unplugged my ethernet cable and switched to airport. Guess what.... started experiencing all kinds of strange behavior, mostly a lot of pinwheels and process hangs. Had to force quit a lot of them. Strangely YT videos still were playing fine, at least in Firefox. Forgot to look at CPU usage but now that I've gone back to hardwired ethernet and disabled airport again everything is back to normal.

    Hi all,

    Bill Maxwell helped me switch my Airport Extreme setting from 2.4 GHz to 5 GHz this morning. Where I have usually experienced 7 or 8 spikes per day if I had loaded anything with Flash player AT ALL, now today after the switch I have had ZERO spikes. None. Nada. I have had Flash loaded and was playing my game on and off all day.

    Maybe this will solve the issue for those that can switch to 5 GHz on their Airport. The switch is done using Airport Utility.
