I was thinking of buying a new iMac in October when they have Leopard out, but I'm reading a lot of posts where some of the iMacs are freezing up, and the only way to "unfreeze" them is to use the power button and turn it off. I was just wondering if there are a lot of iMacs users that are still experiencing this, or has this been resolved?

    Hi, there are probably many thousands of the Ali"macs with the big HD being used..I would think that not all are giving issues!!! The forum is like a medical clinic -> sadly mostly sicky's (macs I mean) ..
    I would rather a smaller internal HD and a stack of externals...I don't like all my eggs in one basket..L

    Not to worry about it just being on the 500GB HD ones! I have the 1TB hard drive and it is happening on mine too. If I'm heavy into graphics like a game, Parallels, or video stuff, it sometimes freezes. I'm just hoping a firmware update comes out soon.

    I have also been experiencing a lot of freezes on my new Imac. It seems to occur mostly when iTunes is running. If I go into the ITMS and browse TV shows it almost guaranty a freeze. Whatever was going on at the time continues so if you were listening to music it continues to play. The mouse pointer moves but you cannot select anything. Tabbing through apps doesnt work. Volume keys and brightness are also unresponsive. The cap locks button turns on and off. This also happened while listening to iTunes and playing a game at the same time. It only seems to be happening in iTunes the only fix is to power your machine off and reboot. I feel like I am back on my Windows box. If iTunes is not running it seems to work fine. I wish I had not updated to 7.3 when I first setup my new Mac . I also have a 17 inch core duo that does not seem to have the problem with iTunes. However, since I bought my new iMac I haven't been using it as much.

    I purchased a 24 in. iMac in early March of this year. About every 4-6 weeks I have experienced freezes which required a power button reboot. You will find a comlete thread of my experiences with this iMac posted in this Forum. The problem seems to be with 24 in. iMacs having the Seagate 500 GB HD and an Apple Technician responded in my thread and confirmed that he has seen the problem. How prevalent this issue is with iMacs is not clear and I doubt that you will ever be able to ascertain that information. Perhaps the more important question is how timely does Apple address the issue of freezing iMacs. There are some posts that indicate delays of a week or more in getting their internal HD replaced by Apple. I have not yet taken my iMac into Apple since it is presently working and I do not wish to take it into Apple until it fails again and is not useable without a complete reinstall of OS X and a restoration form my backup.

    Here is one suggestion. If you are able to purchase an iMac from a local Apple Store, talk with the store manager and point out that there are a number of reports of freezing iMacs apparently associated with a flaw in the Seagate 500 GB HD installed in these iMacs and ask how long it would take to get any iMac that you purchased repaired should you experience that problem. Hopefully, the answer you are given will be an honest one.

    A second suggesion would be to purchase an iMac witheither a 250 GB HD or a 750 GB HD. A friend of mine purchased his iMac at almost exaclty the same time I did and the only difference was that he purchased the 750 GB Seagate HD in his imac. He has had no problems at all with his iMac.

    My iMac freezes with any game program it tries. I decided to switch to Mac after seeing the pretty new package and now have buyers remorse. I bought the extended AppleCare product and cannot figure out how the heck to get help with my freezing iMac. Although I mostly want to work on my computer, occasionally I want to plop the kids in front of a game and not have to trouble shoot a freeze and have to use the "Hold the power button 6 seconds" trick that I just junked my old PC for forcing me to do. This *****.

    Last month I moved to Japan. I shipped my 24 inch imac with no problems. I used it for several weeks. Last Friday evening I put it to sleep. On Saturday I went to wake it up and it would not wake up. I turned off the power button and turned it back on to no avail. I have the white light in the front constantly on. I do hear the hard drive spinning and then stopping. The fan doesn't come on then. I have tried to reset the PRAM but I don't know if I did because it stays asleep. I unplugged the computer, plugged it back in with the power button depressed and then let go of the power button. I then pushed the power button, but only get the fan which blows quite loudly. I attached a seperate USB keyboard hoping that would do something but nothing happened. I am really at a loss. It stays in perputual sleep. I am referring to it as my Rip Van Winkle Mac.

    Hi autiger

    I'm on my 14th replacement 24" iMac. Most of them had bad colour uniformity across the screen, 2 of them had 500gb drives that *totally failed* (booting to a '?', all data lost), and my present hard drive (a Seagate 500gb) continues to worry me as lock-ups are still happening despite me thinking I'd fixed it after unplugging my empty iPod dock (which did give some relief to the symptoms for a couple of weeks).

    I wouldn't buy another. Tarting up the case with glass and aluminium doesn't go any way to resolving the critical flaws many are experiencing. Apple R&D has focused on the wrong issues!

    Good luck with your decision either way. If you are smitten with the machines, go with the smallest internal drive and keep your work on externals (plus a clone of your start-up volume) - then should the internal drive start playing up (or even fail), you can be back up & running without any loss of data.

    I can assure autiger that I have the Aluminum Imac. 24" 2.8 Ghz with 2 Gigs of ram with the 500 Gb hard disk. Up to now I haven't had any freezing or overheating issues. It's now 2 weeks old.
    I can't speak for others of course but in my case, no problemo.
    BTW, it's on most of time and I use intensive programs such as Photoshop CS3, Final cut studio 2 (As I work from home) but do not play any games.
