    Overheating makes sense. I've found the 2 finger swipe gesture doesn't get recognised if your fingers are too close together. If you keep them in a slight V shape its generally fine in my experience. (no middle click is killing me though, 2 steps forward, one step backward)

    I cant believe the slowdown problem is so widespread. Surely their QA team ran builds for more than 30 mins?

    I just got 27" iMac and have experienced the same slow choppy flash video everyone is talking about. I was in shock because I can't play a YouTube video without it sounding terrible. I returned it and exchanged it for a new one and have SAME experience. It feels awful... and I tried a new browser (firefox) and nothing. I have perfect connection. It doesn't do it every time but when slows down like that its just painful and awful.

    Is flash consuming CPU on video playback only?

    If so, can you try to disable Hardware Acceleration in flash player?

    1. Open any page with Flash object
    2. Ctrl + Click on it
    3. In first tab uncheck "Enable Hardware Acceleration"

    Another suggest, to see how changes CPU load on H.264/FLV video playback in flash. Youtube use H.264 for HD/HQ videos and FLV for SD.

    Has anyone run Windows under bootcamp to see if it's a hardware issue?

    no Apple does not monitor these boards. which is why folks need to contact them via AppleCare, the genius bar etc. have details of what is happening, what you tried. be specific.

    also Adobe has admitted to problems with Flash 10 and at least some of the ATI cards. perhaps this is another one for their list. has anyone actually tried downgrading Flash

    folks might want to do some googling on the upcoming 10.6.2 update. because graphics is one of the issue, if appleinsider can be believed, is being addressed.

    6-7 hours later on 2nd 27" iMac and still no problems... Maybe it really is just "some" machines.

    Just a quick note. I too have had all the problems everybody has mentioned but I noticed after I installed windows 7 through bootcamp the computer works fine! Absolutely no slow downs or sluggishness whatsoever. This tells me in my case anyway that it's not a hardware issue but a software/driver issue in snow leopard.

    Hey has anyone tried installing good ol' Leopard on the new machine...
    10.5.6 perhaps?


    I know its not a valid solution but it might help to see if problem is with the Snow Leopard package in general. Some hardware incompatibility issues or such.

    Just to clarify things, are all of you with the new iMacs having ATI Radeon HD 4670 or it happens also with 4850???.
  • EBFoxbat Level 1 Level 1 (0 points)
    I thought no one had a 4850... isn't that what's causing the "November" Ship dates?

    My 27" iMac is having major performance issues. It's not just Flash. iPhoto slideshow transitions are choppy, Pandora streaming music skips and cracks up, game performance is slow, iMovie videos are choppy (audio and video lags) - it's a mess. I've worked with Apple Care for hours - cleaned up libraries, zapped the PRAM, reinstalled the OS; but it's still not fixed. The Last step they had me do was to run a diagnostic program and send the results. Their engineers will look at it and get back to me.

    However, I think I've run out of patience. I have a perfectly working iMac 24" sitting next to this one, and after getting off the phone with Apple Care, I looked at it and thought, why am I going through all of this? I've looked at the return policy and it states, "Except where prohibited, a 10% restocking fee will apply to any non-defective item that requires Apple to perform rework prior to resale; please ask a Mac Specialist for details." As this is clearly a defective item, I plan to take the 27" back today, and buy at a later date when all the bugs are worked out.

    The problem is with Air Port. Disable the wireless connection and plug your computer directly into the router. It will fix the issue. My 27inch works great now.
  • jared.mcneill Level 1 Level 1 (0 points)
    I am seeing the same symptoms not only with Flash but with other applications as well -- Call of Duty 4 for example. A reboot seems to fix it temporarily.

    It's unlikely that networking has anything to do with Core Animation effects being crappy.

    It's almost certainly a OS issue. Since reports suggest that Windows 7 runs fine, that rules our both hardware and firmware.

    Since the software is newer than Leopard, users can't put Leopard on the new hardware. I'd surely hope that 10.6.2 fixes all the problems.

    I see some people have reinstalled Snow Leopard. If it's a corrupt or somehow out-of-date Snow Leopard build and it's also what's stamped on the OS Disc that comes with the iMac, reinstalling might just reinstall the same problems.

    I doubt it would work (since I suspect driver issues not OS issues), but has anyone tried installing a 10.6.0 retail disc and then updating to 10.6.1 to see if it reappears?
