IMac :: Semi Frequent Freezes - Force Manual Power Down
Jan 20, 2010
I have an older iMac, 2006 white version, running leopard. I am one of the many people who experience semi-frequent freezes which forces me to manually power the machine down. After much research it seems everyone has diagnosed the problem has hardware, specifically the graphics card running hot. I installed smcFancontrol and have ran it for four to five months. Since then I have experienced maybe 4 or 5 freezes, but the freeze occurs while doing nothing "heavy", just browsing in safari or chrome. Has there been any updated or new information concerning this problem? I have scanned the web a little and can't really find anything really recent. The most recent article/discussion i have found is roughly a year old.

My macbook pro's HD is in bad shape. S.M.A.R.T status is not ok. Sometimes the OS freezes, but so far this is the main problem I detected so far. Until now. I reinstalled the OS X - clean install - to see if things got better, but no luck. Although I think the system is more stable now, the machine is unable to restart or shut down as before. I have to hold the shut down button for a couple of seconds. With this in mind, is it dangerous for the machine to do frequent force shut-downs, or it just deteriorates the HD even more?

I have the problem that I need to frequently power cycle (shut off and on) my dsl modem to maintain a reasonable speed with my internet connection. It is making the internet experience pretty user unfriendly. Does any one know whether there is a way to optimize my internet connection such that this is not required so frequently (couple times a day)? I am on my second dsl modem, and the same problem has occurred with each of them. ATT simply advises me that my solution is to power cycle the modem to sync the system, whatever that means.

For a few days now, my 13" MBP (purchased in August; painfully clean-install upgraded to Snow Leopard in October) has been freezing into spinning wheel mode randomly every few minutes. It would seem that this happens particularly often in web browsers (but also when no browsers are operating and I'm typing away in Text Edit or chatting in Adium and Skype). When the browsers are on, the FlashPlayer would occasionally crash. No matter what app froze first, whatever else I click on also freezes.
The freezes happen most frequently after the computer has been to sleep and woken up by opening the lid. The wheels go spinning for up to two minutes, and then everything goes back to normal (for up to 3 mins before freezing again). The longer the comp operates after that, the rarer they become, and after a few hours they rarely happen at all (then again, some times they do anyway). On some occasions, everything freezes so badly I need to hard-reset, and then it takes the comp upwards of 15 minutes to reboot - and then everything keeps freezing, of course. Contrary to other reports of similar problems here, no CPU jumps appear to be happening during the freeze. I tried:
- Running Disk Utility after booting from Snow Leopard . Some permissions (which in forums here were referred to as inconsequential / not related to freezes) were repaired; HD in general "seems to be ok."
- Running RAM tests (with Rember, supposedly updated to Snow Leopard). Everything seemed fine
- Getting rid of the ARD agent (which was related to some of the permissions mentioned earlier)
- Stopping Bluetooth (as someone here with a similar problem thought it helped)
- Installing the Beta Adobe Flash Reader (same as above)
Nothing helped. I really don't want to take it to the lab; I live in Israel and the comp was purchased in the States, which means that the only licensed lab here reserves the right to keep the comp for up to 26 working days

Ive been getting this issue on my macbook quite frequently now; dont think its hardware related and occurs randomly at any time up to 3 times a day where the computer will slowly begin to freeze.Â
It (usually) begins by my browser not being able to access a website (just a white screen in browser section), at this point im able to alt tab between apps for some time but eventually everything will hard freeze, same with the cursor which will turn into a rainbow wheel and also eventually freeze. Â
Can only resolve this by power button for 6 secs (good thing it starts up in 5 seconds)Â

I'm using my G5 for both personal use and work so it's on all the time. It has worked flawless with this same hardware config for almost 2 years, but for the past week or so I've had about 4 to 5 kernel panics or complete system freeze a day. This happens when doing web browsing, Final Cut Pro editing, playing a game etc, so basically I can't pinpoint it to a specific application, or to a piece of hardware I've added. I have ran REMBER to test my ram and all seems fine.

Say an app has crashed and I then bring up the force quit dialog. I then select the app I want to kill, and press the force quit button. Now as the little popup that says "Are you sure you want to force quit" is coming down, my machine freezes. This has happened 3 times exactly the same way. Other than that, the machine is smooth as clockwork. I'm kinda thinking there is some sort of GFX card bug or something?

I installed 10.5.2 just about an hour ago, and I've noticed that my Dock is having serious Stacks problems now. If I have the Stacks set to List, there's no problem, but if I try to use fan or grid, the whole Dock freezes and I have to force-quit it from Activity Monitor.Anyone else having this problem? I'm experiencing it on both my Power Mac G5 and on my MBP.

I purchased the new 13-inch Macbook pro on the day of its launch and since the first 30 minutes of use it has constantly frozen intermidiatly for apperently no reason. I've tried re-installing the OS, taking it to the genius bar(They said everything looks ok and on the repair sheet it said "UNIT IS RFB"), and resetting the SMC. I checked the kernel log and it has a tendency to throw this: 7/4/12 12:02:42.000 AM kernel: Previous Shutdown Cause: 3. Read up on this and apperently it has to do with overheating issues, but this doesn't make sense condsidering it can happen even when just doing textbased web searching(I do not have adobe flash installed). I tried ressetting the SMC, changed nothing. Some days it may only happen once or twice, but sometimes it happens so frequently that the computer is barely usable. Apperently I am not the only one having this problem, some people are reporting the same thing but claiming it to be a problem with the Intel 4000 graphics card. The model is the baseline 13-inch Macbook pro running OSX 10.7.4.

I just bought a Macbook Pro. When using safari, it freezes at least once a day to a point I can't force quit, and had to do a hard shut down. I've figured out that if I am using my computer and safari for more than a couple of hours, Safari just freezes. An apple support representative did mention that laptops were not meant to be constantly on, so I have been shutting it down when not in use. Still, I shouldn't have to shut down after an hour just to keep Safari from freezing. Â
Does this sound normal? Is there an easy fix? Do I need to look at getting this computer replaced? Or should I download a better web browser?Â
I'm also new to Mac, and thought switching from a windows would mean better reliability. So far I have been unimpressed with my computer. I just want it to work without worrying about having to force it to shut down once a day.Â

I am using a MacBook Air. When I attempt to select a file for uploading, Safari freezes and the spinning ball goes on and on. Example: When attempting to select and upload a document from my computer to the google drive, the wheel starts to spin when attempting to choose a file. I am unable to upload anything due to this issue.Â

For the past couple of weeks we have had a problem with itunes causing the computer (an iMac running OS X 10.5.5) to freeze and we can't even do a forced quit, but must turn off the machine manually. This seems to happen specifically when we are in the itunes store, not just working with the playlist. The computer has also frozen when in safari - the last time when we were trying to copy a page into Word. We thought it might be a wireless connectivity problem, but I have switched to an ethernet connection and still have the same problem happening.

The problems:
Yesterday and the day before were particularly warm. I didn't really notice until yesterday that my computer was running particularly hotter than normal, even while sitting on my desk for long periods of time. Later in the day yesterday, it was pretty warm and my MBP was running hotter than normal for just sitting on my desk. Noticeably hotter too. At the time, I was running quite a few programs: Safari, Firefox, Msn, Text Edit, and possibly Photoshop as well.
All of a sudden, when I try to open Photobooth, the computer freezes itself for the first time since I can remember... it takes nearly 5 minutes to unfreeze itself, force quitting Photobooth in the process. I wasn't sure what was going on, so I tried opening Photobooth again after everything was back to normal. Same thing, but this time it was taking even longer to try to unfreeze itself. I got kind of impatient and pissed, so I closed a bunch of programs. Tried to log into msn to tell my friends why I left randomly... and yeah, the computer freezes up again. I tried to click into the Finder to force quit the program, but the Finder freezes up and won't even open the "force quit" panel. At that point, I waited a few minutes and then forced a shut down via holding the power button.
I waited a few minutes again, and tried to turn on my MBP. I log into my account like normal... my desktop image comes up, but it just sat there. No files, no HD, not even the Finder toolbar at the top showed. I let it sit like that for about 15 minutes. Nothing. Fed up, I forced a shut down again. Closed the lid, and went to sleep. The next morning, it was cooled down considerably, so I started up the computer again. Same deal, except after about 15-20 minutes the HD image loads. And then a minute or so later, my files load, along with the Finder toolbar at the top. Hooray! ...not really.
I open up Safari. Things seem alright. I get to my email, then try to open Firefox. Firefox immediately gives me the "Well, this is embarrassing..." message upon loading the window, and about 20 seconds later quits itself without warning. I tried opening it a couple of times, nada. Same thing happens over and over. Same with Photoshop. I haven't really tried any other programs... because eventually my problems got worse.
I went through the day taking notes for my classes on Text Edit, because apparently Text Edit and Safari are okay with my computer at the moment (using this right now, actually). When I get back, I try to restart my computer to hopefully give it a chance to shut off and start up again to fix the application force-quitting problem. Worse. It goes to restart, and then gets itself stuck on the load image of the purple aurora/galaxy default desktop background. Considering the issue that I had that morning, I let it sit for a considerable time. Nothing happened. So I had to force a shut down again. The ONLY way it seems to be able to start up is to force the shut down and then start it up again. The desktop takes several minutes, if not 5 or more, to load my desktop files. If I try to do anything upon it immediately loading my files, icons, etc., it will freeze up for several minutes trying to execute the command. Ex: clicking on my HD to get to the Disk Utilities application. Eventually, I got the Disk Utilities to open and run a disk repair. The repair was quick and suggested only a few issues with things like Quicktime.
^ it was a bit too late at this point to call a mac place about my issue, so I called my parents. I tried to print something out for my mom via Text Edit and the computer froze up again. Couldn't even get the Finder to unfreeze itself. Forced a shut down, and now I'm here. Safari's up. Just about the only thing that is actually still working. And so is the Disk Utility.
I'm unsure of what to do next... I have two external HD's. One is brand new, nothing on it. I'd love to attempt backing up all of my files before taking my computer in to get it checked out. Not really 100% sure how I might attempt that, considering the way my computer has been handling doing much of anything at all lately. Any advice on what to do next before I take this sucker into a mac shop would be really great.
~Admittedly, I don't treat my computer the best that I could... once I left it on my bed for a while and it had to shut itself off because it overheated. It was fine afterward, but a few times I've fallen asleep after leaving my computer on my bed. When I would wake up, I would immediately check it. Sometimes it would wake up from being asleep (checked the temperature; usually not that warm thankfully), other times it seemed to have turned itself off. I attributed this to the battery running low... but I'm actually not sure. Maybe I let it overheat itself again? I'm not entirely sure, sadly. This is my first laptop though, so I'm kind of slowly learning the "no-no's" of how to treat my computer. Thankfully, I read enough around here to invest in the extended warranty.

Eagerly awaiting my ship date for a new iMac (having been burned by two models with screen problems at the end of last year... another story). But I face three choices when it arrives to replace my trusty MB.
1. Use Migration Assistant to bring over apps, files, my library or everything.
2. Restore from my most recent Time Machine backup.
3. Manually re-install my apps and simply move across my files and folders.
Does anyone know whether there's any benefit to the "cleaner" option 3? Is there any difference between 1 and 2? I feel instinctively that my prinstine Snow Leopard-powered iMac would be better off for the minimalist option, but if there are no concrete advantages, I'll let Time Machine take the strain.

Since installing Lion I lose my wireless internet connection frequently - only from the IMAC, not from the IPAD or Dell. I called support and after quite a lengthy "try this" session, I was told that this was a known problem. I can always get it back but sometimes have to unplug the router.

I have an old "vintage" Macbook with Tiger as my OS. I have all sorts of sleep issues with it, and recently after accidentally hitting the sleep button, I had to force quit the machine by holding down the power button because it was just (beachball) spinning when I tried to start it up again.Â
I went to start it up and I get the gray screen with the apple on it and the spinning "clock hands" this goes on until I get a darker screen without apple and more spinning. It stays there. We've tried a host of solutions including the resetting through battery removal, we've tried to "archive and reinstall", etc.

A few weeks back I spilled a glass of wine on my non-unibody, but new, MacBook pro while it was turned on (I know; no good). i let it dry for a few days but still, no life. i decided to open the sucker up to investigate and had successfully taken out the battery and one of the fans before the trouble began. i was using a #000 philips head screwdriver, and most of the screws in the logic board came right out, but some (the same size as the others) wouldn't budge. now i'm not sure if i should just put the thing back together and send it to apple or try to find a different size screwdriver and forge ahead. i know the problem in terms of moisture is on the other side of that logic board (and hard drive, which won't budge either)

I'm relatively new to OS X and love it. I've found counterparts to all of my old windows software I rely on except an image editor. I use to love paint.net on windows - I do lots of image editing where I need something more powerful than paint on windows (or paintbrush on os x), but don't want the learning curve and extra features of Photoshop or GIMP. Also, I'd like it to be free if at all possible.

I have just bought aluminium keyboard from Apple and sadly, I have the same problem described here, in this post: http://discussions.apple.com/thread.jspa?messageID=5593479
Every 5 minutes the keyboard freezes for about 15 seconds. My Mighty Mouse and tablet connected to the keyboard won't work as well. I have tried to connect it to other usb ports but there's no difference at all. Please help, as this issue is really frustrating..

Over the last few months I've noticed a trend with my dual 2GHz G5 at home, it often locks up and the fans go full-throttle. It sometimes happens when I'm using it and often when I leave it idling for a while. I've noticed that the CPU A and CPU B temperatures start around 120 degrees F when the machine is first powered up and steadily climbs to around 150. Is that normal? The dual 1.8GHz G5 I have at the office doesn't run hotter than 110 degrees. The fans haven't failed. Is there a coolant link? Is there anything I can do to diagnose this, or do I simply need to call AppleCare?

Given the Air's current mothball status, I'd buy an antiglare 13" MBP in a heartbeat. But black slab of highly reflective glass = no sale. They do it on the leviathan 17", and now on the top spec 15" (or lower spec if you BTO) albeit at a cost of 120 notes. But no 13". Can anyone provide even a semi-rational (i.e. practical) explanation as to why not, or is just the worst side of Apple we're seeing here?
