    sorry to be a little out of the topic, but this sounds exactly the same problem with Macbook Air (1st rev) 1-2 years ago. Everytime flash videos are playing. CPU usages get way over 100% and it's worst then the Imacs situations here as you couldn't do much even moving the cursor around were very slow.

    Apple issued a few firmware fix but it didn't really work. So the solution was to use Coolbook App. It worked like a charm but my MacBook Air gets way over 100 degrees sometimes when Flash video is playing (usually with 2-3 windows playing - loading at the same time). It's really really hot as the normal temp of any apple computers I've been using are only around 50-75 degrees Celsius max.

    Though I have to live with that problem since. Apparently Macbook Air Rev 2 fixed it . But with Rev 1 (like mine) that's basically it.

    I also see very slow & choppy flash performance with my late 2008 15" MacBook Pro.

    I have the stuttering also on my 21,5" iMac with only a 9400m chipset. So it's not a videocard problem. I experience this problem during skyping and less while browsing.

    I use skype a lot so I hope that Apple will fix this problem soon because my skypecalls aren't that comfortable at all right now...

    Good Day All

    I am making an effort to appear upbeat while, in fact, I am quite perplexed; I have a 27" fully tricked-out iMac Quad SAVED to my Online Shopping Cart but I will not proceed until Apple Issues An Official Announcement Regarding The New iMac Performance Issues and the Reviewer/Critics agree that the issues have been resolved.

    I am both disappointed and frustrated because I need to upgrade my current and recently announced 'Officially Obsolete' iMac.

    Trying my best to remain loyal but ambivalent about what I see as a totally avoidable situation.

    I cannot, of course, commend Apple for this regrettable fiasco.

    What do You think ?

    Thanks folks, after disabling AirPort I am no longer able to reproduce this issue.

    I've been having the same problem for the last year on my Imac 20" from 2005....every now and then after a reboot it'd work ok for a few min, than revert to choppy playback - sometimes no video playback, but the sound would be fine.

    Last week I got rid of Flash 10 and reinstalled Flash 9, and it's definitely much improved, but not for all videos. I also just bought a new 27" I7, with 8 gigs, figuring that would easily solve my problem, but now I'm hearing all these stories of problems with the new systems...!

    Btw, I'm not running Snow Leopard (I've got 10.4.11 running), with just 1 gig or RAM...and the problem with video playback occurs in both Safari and Firefox. Crossing my fingers that with all this feedback and the stories of the issues with the new systems, that the delay in shipping them will give them time to fix the problems.

    Hi,

    You'll find the the answer to your question both at Google News and in Apple Discussions.

    I am following the news attentively and I have suspended my iMac purchase...

    I've got an identical set-up to you (2005 20" iMac running Tiger) and don't have a problem at all with flash - I've also upgraded to Flash 10.

    I've got more memory though so maybe that's your problem.

    From what I have seen the following step will fix this issue temporarily - Flash video will play normally if you click on the AirPort menu extra and let it scan for networks.

    This works for about 20 minutes to an hour. Once the issue starts again, repeat the scan for networks.

    Best of luck. Let me hear how this works out for you.

    Went to store before hearing about these issues. In Store tried playing "Matrix- Reloaded" to sample the screen resolution. I used the 21.5" and 27" iMac's as well as the NEW MacBook (Polycarbonate). All quite stunning to view. MacBook was a special surprise in viewing detail compared to last model. BUT, when playing the film on the 21.5' load time seemed normal and visual was stunninng. Switched to the 27" iMAC next to it (one of two 27" on display). Start up to recognize the disk seemed awfully slow and had to close a window someone else had opened when they were looking at the onboard software. When clicking to close the software window it "stuttered" several times before closing which immediately caught my eye. DVD played okay but honestly the 21.5" seemed to be much more detailed. That may have been reflection from lighting in store but not sure. Then decided to check out sound of the new speakers on both. 21.5" was amazing boost from past speakers. Really crisp with good volume even in the large open space of the store. Then tried the 27" and was shocked to turn it all the way up and hear a muffled music at half or one third the volume of the 21.5". I know the base model 21.5" uses Nvidia graphics card but the 27" is ATI Radeon. Research shows NVidia known for issues with their chip production/design issues. But the 27" uses ATI Radeon by AMD. Also a MAC friend mentioned that it is likely software related since there is 140+ known issues with the new Safari which are to be corrected in the next major software fix in December. I also have had the experience of a large number of issues since I originally downloaded the Safari 4 BETA. My iMAC is a dome based 800 mghz G4 system. Once i downloaded the BETA version no video would stream properly (non-HD versions included) where sound and video sync are off by 30 seconds to 1.5 minutes depending on size of stream or download. Hope it is corrected soon!!!!

    there are some signs that the Flash issue is not an Apple issue but an Adobe hasn't actually created a version that plays nice with Snow Leopard and Safari issue. so some of this griping should be CC'd to Adobe to cover all bases

    I think I may have solved the iMac slowdown issues, check out my post here:

    Just like many of you guys, my 27" iMac is suffering from the slowdown. Not only flash video, but system wide. My attempt at quantifying the slowdown consists of:

    1) Running xBench on fresh system: 177 points
    2) Let OS X idle for 3 hours.
    3) Running xBench after waking up: 20.84 points!!!!

    All except one part of the test resulted in a significant loss of performance. The unaffected (within margin of error) test was Disk Tests.

    The biggest looser seems to be Quartz, which went from 246 points to 12.

    Now I'm hunting for a solution that doesn't involve my new workstation being offline for an entire day.

    I also have a 27" iMac - Performance Issues - did have them - but then I took a pragmatic approach to looking at my configuration and I discovered that my configuration was to blame. I feel that for many who are reporting this issue - the same may be true.

    See... most people complaining about this issue are using iStat to report their CPU usage. Like many Mac Users - I had iStat installed too. I would notice incredible system slowdowns when running xCode that occured on the 27" iMac, but not on my Early 2009 Macbook Pro.

    Given that my MacBook Pro still is running Leopard, and the iMac is running Snow Leopard - I started wondering about software incompatibilities. I had noticed that my keyboard buffer would appear to lag way behind my typing, and periodically, the mouse would just pause.

    Looking in iStat - I saw that the finder process was taking ungodly amounts of CPU time - up to 103% at times.... Searching the net - I saw tons of images of people showing incredibly bad CPU performance in iStat.

    So then I said to myself - Whats similar with this and why doesnt everyone have this issue. And then I noticed that most of the pics were people using iStat. Now - before you say anything let me say that I installed the latest version (2.0) which claims to work with snow leopard.

    So... to test, much to my dismay, I removed iStat. Upon doing so, my CPU went from 104% spikes in activity monitor to damned near zero and I have yet to see another performance issue.

    Details are in my blog post here http://www.nedvedtech.com/post/2009/11/03/27-iMac-slow-performance-when-using-Fl ash-BS.aspx - but until someone can prove otherwise, for me, iStat appeared to be the problem.

    I can only assume that many of these other problems people are reporting are also self-inflicted. Look at what you are running in the menu bar and in the background before you report that the world is ending to apple

    Let me prove you otherwise by saying that I had the problems and don't have iStat even installed
