Brought my iMac to store because it kept shutting down and rebooting on its own. Been 12 days and still haven't heard back from them and when I call I get the run around of the computer repair being "in progress". What to do next?

View 6 Replies View RelatedYesterday my wife's iMac froze and she tried powering off manually by holding the power button down on the back of the machine. Then she tried to boot it back up and got the welcome screen but she couldn't select an account to login to. Tries restarting again and gets a blank blue screen.Â
Call me out to take a look.Â
Not knowing much, I googled some help sites and performed the following:Â
SMC reset
PRAM reset
Verified disk permissions and repaired disk permissions
Boot from install disk (repaired permissions and verify disk)Â
Restarted and everything seemed to be working fine. Until this afternoon. She was in the middle of an upload and the computer restarted itself. She's in the middle of the upload again (almost finished). But when it's finished, I'd like to troubleshoot this some more.Â

I have a late 2010 27in iMac and it has shut down randomly by itself 4 times in the last month or so, including twice in the last couple of days. I have 16G of RAM and am only using up to 8G ever. Just to be clear, it shuts down and does not restart automatically. I never have the screen brightness higher than half so I don't believe I am overheating it? I really want to know why this keeps happening.

I have an i mac (quad core) running on Mac os x 10.7.3. I am finding increasingly that despite me closing all programmes properly the mac doesnt shut down. I find it goes to the grey screen and the mac spiral appears, I have to push the power button to shut the machine down.

A message will pop up saying something along the lines of - Safari unexpectedly closed - and will have the options to report, reopen or close. I know it would be useful for me to tell you exactly what it said, but by the time I opened up a new Safari and logged in, I've forgotten what it said, it did however mention "Steinberg" something.

My iMac is shutting down whenever I try to open an app. Everything was going fine, then I tried to open Skype and was forced to shut down the computer using the power button (there was no error message, just this message to shut down using the power button). I restarted it and deleted Skype thinking there was something wrong with the app. Then I tried opening Firefox and it asked me to shut down again. And it does it whenever I try to oPen any app.

How do reload the iMac,,,it has a bad volume and keeps shutting my iMac
Info:iMac
For the past two nights, my iMac has randomly completely shut down. I set it to sleep before going to bed. When I woke up, it was shut down. And the weird thing is that it was shut down, and when it started up, no applications or anything were open. Generally, I'll shut down and it keeps everything open and running, then when I turn it back on, everything is where it was. I don't know if I lost documents or anything... or everything. I've never seen this before since getting Lion.Â
I checked my energy saver schedule... I had it set to SLEEP at midnight. But it is never set to shut down or start up. And even if it was, why are all the apps closing when it shuts down?Â

I have a MacBook which has recently been shutting down when it feels like :/ this all started a week or two ago (well not the shut downs but other issues that I'll get too), basically the fan I think has been knocked as it is bumping the top or something as the whirring is getting loud and it sounds like every now and again it hits something
Also CPU usage seems to be averaging out at 20% for Safari and 100% for HD Video where as it used to be very small amount for Safari and 30 - 40% for HD.
Just want to know if I can shutdown my imac without having to write everytime my admin name and password?

Lately my iMac monitor keeps shutting off every couple of minutes. It seems like its in sleep mode but if i move the mouse or press a button on the key board it doesn't go back on. I have to press the power button 2 times to get it to turn back on. When the monitor turns on everything is still there right before it shut off.

As of yesterday my battery no longer holds a charge. Was running fine on the power cord. Now this morning when I boot up the computer. It goes on the apple loading screen, gives me the apple sound but instead of loading into the desktop. It goes back to the gray screen with the apple in the middle loading. It does this repeatedly and won't load onto the desktop. Need some advise on what I need to do. I'm also not sure if I have any of the original boot disks.

After a few seconds the mac will reboot. This happens almost always, and it makes the mac unusable to work on. When i do not start any applications on the mac after boot it will keep on running, but as soon as i start an application it will do the same. Â

I've had my Macbook (10.5.8) for over two years and have had no problems until recently. It's crashed twice in the past month, and before that (for a few months) it has been extremely slow. I've cleaned out everything I didn't need and placed most of my documents onto a external hard drive in hopes that this would speed things up - it has not. When the thing crashes it basically reboots itself with out any warning, losing my data. Both times this has happened I had photoshop and Acrobat 6.0 Professional open (I've been editing photos of texts of my research and turning them into pdf - some of these files are quite large (400 colored pages) ie. 600mb). The system usually crashes and reboots while I am editing an unsaved pdf in Acrobat.

But I'd rather have it automatically log in to OS X, since that's the OS i use 99% of the time.

I am currently using OSX 10.5.8 Leopard and have run into a problem. When ever I attempt to mount a .DMG file, Finder goes unresponsive and will not re launch. The .DMG is downloaded from a verified clean source and the default program to open is the Disk Image Mounter Utility. I try going to /System/Library/Core Services, and I see the Disk Image Mounter Utility listed, yet when I attempt to open it, nothing happens and it is not even listed in the activity monitor. I have tried mounting several .DMG files and each time the same problem occurs and can only be solved by rebooting the system. I have just recently tried updating my software to the latest version and still no fix.
