IMac :: Not Freezes - Wifi Related?
Apr 26, 2009
So I've had my iMac about a week now. I started a thread about not having any freezes. Well this weekend I experienced two. Both of which occurred while using iTunes (once while importing my old library into iTunes from an external USB drive, and once just having iTunes open). Not much rhyme or reason to the freezes nothing in the crash logs. This is slightly depressing, since the replacements people are getting seem to freeze as well. I still don't think this is Wi-Fi related. I just think there's a serious conflict between the ATI 4850 chip and the rest of the hardware. This is pretty much unacceptable for a new machine.

Right now I'm saving for the 20" model (2.66). Would The 20" 2.66 iMac Freeze Like The 4850 Issue? Will it freeze like the upper model with wi-fi on? Making sure before I invest in an iMac.

From time to time, as I am composing a message using Gmail in Safari, the email screen "freezes." I cannot continue to type, copy or paste, or do anything else to manipulate the screen; it is as if the page has become an image. I speculate that this is due to some inadvertant "gesture" on my part, as at other times my Safari screen will sometimes zoom in and out unaccountably, presumably because my track pad senses two fingers pinching instead of scrolling. This latter problem is very annoying, but I attribute it to my own clumsiness. The former problem of the screen freeze is more than annoying, as it requires me to completely redo a sometimes lengthy email. Is there a gesture that causes a screen to be captured as an image?

Finally I can reproduce the freezing of my macbook air. If I change from wifi location for example i go to work from home the following happens:Â the MBA will not fall a sleep resulting in a very hot MBA in my bag.the MBA will fall a sleep but it is not possible to wake it up againthe MBA will fall a sleep and is able to wake up again after opening the lid but now it will freeze the entire mac within 5-10 minutes.Â
I have to push the power button for a long time in either cases.Â
I just did a complete restore so i have no extra software installed.Â

I have a newer iMac 24" bought in 11/2007. I have the mini-dvi to vga converter and when I connect it to a external tv capable of 1024x768, the iMac freezes and does nothing. I disconnect and the screen turns blue and the flickers back on and everything works. I have made the connection then booted up, and I have tried every resolution all the way down to 640x480, same thing it just locks up the screen, but again as soon as I unplug the mini-dvi to vga cable from the iMac it flicks to a blue screen and everything comes back. I have reviewed dmesg nothing, and revieiw /var/log/messages. Is there any troubleshooting I can do. I am old school unix/linux guy just converted my family to Apple and would like to use the display on my tv to watch my iTunes movies.

I have a 3.06 Intel Core 2 Duo iMac with Snow Leopard. It is completely up-to-date and has always ran beautifully. I have not installed any new programs lately. Recently, when I go to APPLE > Restart (maybe after an update or just because I like to restart my computer on occasion) the bar at the top disappears, my dock stays up on the screen, and the computer just sits there and freezes up on me. I am forced to hold down the button on the back to get my computer back. Here are the things I have tried:Re-install of the latest update using Combo Update Reset PRAM Repaired Permissions Booted from disk and ran a Repair Disk Complete zero-out of the HD, clean install of Snow Leopard, and reinstallation of everything from a Time Machine backup Nothing has worked...The other problem is that it only happens when my computer is on for several days. If I restart daily, it doesn't happen. So, it makes it hard for me to log-in as a different user for that long to initiate the problem. I think it has something to do with a program that I may open and close throughout the week but I have no way to pinpoint what program it is.

I recently had a hard drive failure in my imac which i replaced with the the samsung drive listed below and a fresh install of snow leopard. Now i am experiencing a problem when waking my mac from sleep. about 50% of the time when it wakes it will immediately freeze which can only be resolved by a reboot. Could this be caused by this new drive being a "green" drive that conserves more energy when asleep by going into a slower state than a typical drive or is this a software issue?

4 g ram

My iMac won't shut down completely any more.It gets to a white screen and then freezes, and I have to hold down the power button to get it to shut down.I have also been getting intermittent kernel panics, maybe one every 3 or 4 days.I went through all of the troubleshooting steps to try and figure out the cause, with no luck. Did a new install of Lion and everything seemed OK for a few days, and then started having problems with programs not responding, not being able to shut down, and now getting kernel panics again.Considering completly formatting the drive and starting fresh with everything, but not sure if that would solve the problem either.

I have an iMac G5 that keeps freezing on me. It occurs more so when I use iTunes. The computer freezes and even the mouse turns off. I have to completely turn off and on the computer to get it working again. Could anyone tell me what it is? Virus?

Having some trouble with my iMac5,1 - Intel Core 2 Duo - 2.16 GHz. It's about 2yrs old. Symptoms include: 1 - freezing when I open, close or move windows too quickly, open too many windows and/or when I multi-task in general. Anything processor intensive is unreliable. 2 - apple mouse cursor shoots off to the side of the screen for no apparent reason and scroll button is unreliable. 3 - lines across the screen that resemble pixel drop-outs - they come and go. I'm still running 10.4. I've wiped out my hard drive twice in the last 2 months and started over from scratch. When I re-install 10.4.0, it seems to run fine. until I run the system updates. That's when my trouble begins again. I've also cleared out my caches and histories repeatedly. I've run the Disk Utility repeatedly. This is getting serious. My PC at work is WAY more reliable than my Mac. I'm considering switching back! I owned a G4 for 7 years and was very happy with it. Was the switch to Intel a bad idea?

My Imac freezes up a lot, usually after 10 to 15 minutes of being on. I suspect it has something to do with overheating. I have to get my data off of the drive before I take it into the Apple store for fear that they will will just replace the drive and all will be lost. I have a fan blowing on it now in the back and am copying data onto an external drive little by little until it freezes up.
I bought it last fall and have a 3 year warranty on it and this will be my second time bringing it in for repair. The first time it was a problem right out of the box when I brought it home and it was replaced. It's a 3.06 processor, 24 inch screen. I am not impressed by the hardware reliability and the all in one system. I am regretting buying the imac after being a PC user for so long and I am using my Windows PC to write this. I suspect the cooling system could be better on my IMAC given the compressed footprint.

I was working with logic pro 8 on a project when the APP crashed. Then, the whole computer became real slow. I couldn't open anything without getting the spiraling rainbow circle for at least 3+min and even then the app wouldn't launch. So I shut down normally, which took a while.
After I left it off for about a min or so, I tried to boot again just to get stuck on the gray screen with the apple logo. I did some research on my phone (since I currently don't have internet because I'm moving this week) and found out how to reset the pram. I tried it, and this time it got all the way to the blue screen where it got stuck. I tried resetting the pram a second time to finally get to the log in screen but everything was going very very slow. Unusable type of slow. Opening a new finder window took at least 2 mins and everytime I ran my mouse across the idock, it would freeze.

I've got a G5 iMac which is 5 years old now, it's got 2Gb RAM and 75Gb HD In the past couple of weeks it really slowed down and then it started having panic attacks and random freezes. It also crashed with a what appeared to be a wierd zig-zag pattern [see attached jpeg - this happens even when the log-inscreen is on] I hadn't installed any new applications or anything and it had been fine upto then. I've ran the hardware test a few times, which has said everything is fine: video, memory, logic board all passed. So I backed everything up, scrubbed the HD, installed a fresh system 10.4, which Software Upgrade then took upto 10.4.11; Installed some of the apps and put some data back on - but leaving about half of the HD empty The random crashes are happening more and more frequently, crashing, panic attacks and i am forced to do a hard restart every time Is there anyway out of this or is it a case of old machine, on its last legs and needing a new one?

My iMac has recently begun freezing momentarily. First it will freeze for a few seconds (while still allowing the mouse to move). It will resume, and then a minute or so later it will freeze again for a slightly longer duration. During this time, I can move the mouse, click on things, but nothing responds. Music and videos pause and then resume, websites stop loading, not able to type, etc. In fact, it just happened while typing that last sentence.Â

I don't have access to the marketplace forum here (not enough posts), I don't want to support ebay/paypal if I can avoid it, and I live in a smaller market area so craigslist is a bit iffy� does anyone have any suggestions on avenues where I might be able to easily sell a Mac Pro-related item?
If it were an iMac or MacBook related item, no problem� but the Mac Pro isn't as popular a product, so finding someone interested seems like it might be more difficult.

I've had ongoing problems with my iMac freezing, especially during iTunes playback, but otherwise random. No console errors or crash report to go on. I tried a fresh install several times, but the problem was still there. Also tried disk repair etc. I happened to try a defrag tool and it completely screwed my filesystem. As a result I had to do a proper format (zero the disk) before reinstalling. The freezing has now stopped! So if you're getting random freezes for no apparent reason, try zeroing the disk before reinstalling. Perhaps some disks weren't formatted properly before shipping in new Macs? The iMac is a Core 2 Duo 3.06 24-Inch (Early 2008)

This is my first Mac user problem posting going back to my original SE! Power PC based imac running leopard 10.5.8 starts up but then mouse freezes after a few mins. Managed to change sleep mode to 15mins - same problem. Can't boot from Disk as same problem, also command+option and shift all still have mouse unmoved! Obvious change of keyboard and mouse have no effect. Could this be related to offspring's addition of ipad plugged into usb a few weeks back? He tends to unplug the device without ejecting!

Has anyone had a problem with their Intel iMac mouse freezing after it wakes up from being asleep. Check my sig for specs. In particular, we have a wireless mighty mouse and everytime you wake the computer from sleep, the mouse won't work. That includes taking out the batteries and putting them back in. Keyboard still works. Is the bluetooth going bad? Could it be the mouse? We're going to schedule an appointment with the Geniuses here in Memphis so maybe they can figure something out.

I recently got the 2.4 20" iMac. Since a lot of people recommended Crucial for the memory upgrade. I went ahead and ordered 4GB from Crucial. I had my iMac for about 1 week before I put in the new memory. I never noticed it freezes on me at all before I put in the memory. After I put in the memory, it intermittently freezes and there's nothing I can do except hold down the I/O button to turn it off. It would freeze for no reason, but I noticed it freezes often when I used Handbrake to rip a DVD or even when I'm in Numbers doing just usual stuff. Finally today I put back the 1GB that the iMac came with, and so far, Handbrake is going OK. Could the new Crucial memory be bad? Should I call them up and ask for a replacement or return? Has anyone had this problem?
