I have a 2006 IMac that works perfectly except for one thing. One day last year out of the blue the sound stopped working and I would get the 'not allowed' circle when I tried to adjust the volume. the problem persisted for a week or so, then the sound just came back on. Everything was fine untill a month ago when the same thing happened. I did some research and tried the toothpick trick and everything related but nothing worked, then the next morning the sound was on. Over the next few weeks the sound would go on and off randomly for no apparent reason. It has now been off for two solid weeks and I don't know what to do. Is it possibly a loose connection inside the computer that just needs to be plugged in?
I was listening to music on my macbook with headphones one night and once I unplugged them my sound stopped working. There is no red light coming out of the headphone jack and when I go to the sound settings it says there are no output controls. I don't know what to do because everyone says theirs has a red light but mine doesn't.
So I have an old imac running OSX 10.3.9 and recently it started making a whoosh sound randomly at will. It sounds like a whiffle ball bat missing the ball. Also for no apparent reason it started saying "you have logged in" every time I wake it up. Any clue how to make these annoying sounds go away and or what may have started them?
My mid-2014 15" Macbook Pro randomly "loses" its retina display at the top menu (becomes pixel-y), where the battery, sound, and wifi logos are (on the top right side of the screen). A restart fixes the issue, but I want to know if this is an issue that can be fixed?Â
IMac 20" intel core duo, 2G running leopard 10.5.8. Mac will turn off randomly and won't start again unless its left for a while, it's no getting hot (that I can detect). So far I have reset the SMC, run the AHT which came up with nothing, tried another power lead, tried it in different power outlets.
My iMac randomly freezes and crashes on me. Most of the freezes occur when scrolling with my trackpad on websites with Google Chrome. I get the pinwheel and have to use the power button to turn off and on the iMac. I haven't noticed any particular connection to Flash websites or video related sites. It just seems kind of random. I've also been careful to have absolutely nothing else running and it still does not prevent it. Â
Also, from time to time the iMac will crash and go to a solid color screen. Either Blue-Gray, White or Black. It seems to be random colors. When this happens, I have to use the power button to cycle it off and back on again.Â
Some info about my iMac: Model Identifier: iMac7,1 Processor Name: Intel Core 2 Duo Processor Speed: 2 GHz Mac OSX 10.6.8Â
What could be causing this or how can I diagnose the problem? I can give more info if needed.
my screen is just randomly going dark. its not shuting down - just seems to go to sleep but nothing I do wakes it short of turning the power button off then on. When I do that it quickly comes on again and seems to work fine. Seems to be happening with more and more frequency and is not particular to any software. I've read the boards here - I'm not a gamer ( no games on this computer) I'm a photographer with lots of files and I use photoshop alot. Yesterday I was on you tube and my screen went dark again but the video was still playing - I could still hear it. In fact, I could hit my mouse to stop and start the video but I couldn't see anything.

my screen keeps going black randomly but everything in the background is still playing. When i press the power button twice it will go to standby and then turns on again, but the black screen keeps getting more and more frequent. Ive tried resetting the SMC and the command+option + PR thing but nothing has worked.
My iMac sometimes will just randomly start playing music. This just recently started and I haven't made any hardware/software changes at all, last thing I did was update it for printer drivers and that was it. It usually plays at night when I'm sleeping and it starts with the song that's on the top of the list. I've restarted it and everything and can't figure it out. I always leave iTunes running because I have my iPad and iPhones set up for wireless syncing. So I usually just keep the sound off to prevent any random music playing. Oh and there is no remotes connected to it either....
My Imac---which is less than a year old--randomly goes black but continues to function otherwise. This is happening on a more and more frequent basis.Â
I'm having huge issues with my 20-inch early 2008 iMac running 10.7.3. I upgraded my RAM (to 4Gb) 8 months ago and everything was running nice and easy until I upgraded to Lion. Either one of these things happen:Â My screen goes entirely grey or blue with white faded thin vertical stripes at random timesMac freezes working with any Adobe applications (mouse cursor still works but I can't click anything until I turn off and on)Mac freezes for a while and after a 30-second delay clicking and pressing buttons frantically everything goes back to normalÂ
The strangest thing is that when I play Sims 3 for example (a beast of RAM and video drainer) nothing happens. I tried almost everything from repairing permissions to re-install my memory modules. I couldn't run the hardware test.Â
Note: I live in Brazil so sending my machine to a Genius Bar is completely off the question.

Only a laserprinter is connected. Sometimes I can work for a few weeks without problem, but then the computer freezes. The computer sounds 3 monotone chimes in a row and repeats this, keyboard an mouse become inactive till I do a hard shutdown.Took the computer 2 times to the Apple store, they tested for a week but apparently nothing happened then.
I have had this for the last few days, so I don't really know what's going on...Â

I have a 27" iMac. Just recently, the screen has begun to randomly shut off. I then have to squeeze the power button, followed by a click of the mouse. This will bring me back to my password screen. Sometimes, that would be it, other times, it will do it repeatedly, for no reason, and then settle down.Â
Just for those of you who are bound to ask me about my Energy saving settings: Computer to sleep – Never. Display to sleep – 15 min.Â
It seems to me that this could be a hardware issue, but just incase any of you have had any experience of something similar, I thought I would ask.Â

I recently had to reformat my iMac because it was restarting constantly and it kept freezing too. After a reformat, I installed a few programs. Skype, Microsoft Office 2010, VLC, Plex Home Theatre, Plex Media Server, an uTorrent.Â
My computer restarted randomly again, twice :-( I included the crash report below if it is useful.Â

I am running an imac 24-inch Mid 2007 on 10.7.3. Always do the updates and everything seems ok. I have been having problems with connecting, reconnecting after sleep and just losing my connection in the middle of being on wifi. I have replaced my wireless router, I have deleted all previous wifi networks. I have also renewed my dhcp license. Nothing works. To reconnect, I have to continuously go to network preferences, assist me, diagnostics, then continue with the assist me and choose my network and it then reconnects. This is not just waking from sleep. Sometimes just randomly while working on the computer. I have read some things about equipment plugged in and I have an ATT micro cell plugged into 1 ethernet jack in my wireless router/modem, I also have a bluetooth mouse, a printer plugged in USB and a Lacie HD using Time machine.

I have full Wifi signal and I'm using multiple device on my Wifi which are all stable except the iMAC. We had a power failure a couple of weeks ago and since then the iMac just won't stay on the network. I have to turn wifi of and then back on to get it to join and that mitt lat 10 minutes.
Ever since receiving my iMac back from the genius bar my external hard used by time machine randomly ejects. Apple Care had no answers for me. They told me I would have to research it then I would be able to fix it?
My 2007 iMac keeps shutting off randomly. I'm running Mountain Lion. I have tried unplugging it from the back waiting and plugging it back in. Sometimes when I have turned it back on, the fan will run loudly.
My internet provider says it has a good signal. whether i use wifi or connected straight to the modem its the same, some pages load some dont, always different on what loads and doesnt.  If i connect to a neighbour who has the exact same internet speed and provider it works perfectly fine. Ever since i did a software update 3 or 4 days ago it has been happening.
It just randomly freezes, cutting off all ability to navigate the desktop.Re-booting the system resolves the problem, but leaves me with a lot of lost work.SOMETIMES taking out and putting back in the batteries resolves the problems, but not often.The kayboard continues to work, so it doesn't seem to be a bluetooth issue.Â
