My 24"intel Imac Keeps going to sleep -it is hot to touch in the top left corner of the case -is something about to fail .

My IMac works for 30 mins without a glitch then starts putting itself to sleep every five minutes after that - it is getting hot in the top left hand corner - my guess is that something is on its way out - anyone had a similar issue before .

Ran AHT - nothing wrong.
Did a full cleanup and verify as well.
probem persists.
Fan is always going
might have to go to an applestore..

My imac starts with a white screen, then goes black and a small white line just blinks in the top left corner of the screen?

My imac starts with a white screen, then goes to black with a small white line blinking in the top left corner of the screen. Any ideas? Thanks.

Try starting your iMac with the original DVD that came with the machine then launch disk utility to repair your hard drive.

My imac 21.5" 2010 model heats up in the top left corner (backside) when iphoto is on ad trying to generate thumbnails? Can anyone help as to why this is. It has been serviced and passed all heating tests? Thanks in advance

I just had my iMac sent away for repair as it kept heating up to the point where you could not touch the top left corner of the machine. It really only heats up when i open iPhoto and it is generating thumbnails for all the events. (Some reason it has lost all the thumbnails).
The Mac came back yesterday and they replaced the fans and cleaned out the machine and it has passed all heating tests.

As user Seventy one recommended above, the "iStatPro" Free software is very useful in determining just how hot your internal hardware components are getting. You could post some of the temp readings from it here so we can comment on them.

HT4095 What happens if the genre box goes missing on the top left corner on your iPad? How do I get it back?

What happens if the genre box goes missing on the top left corner on your iPad?How do I get it back please help me.

Try quitting iTunes and restart your iPad.
Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
You can also try a reset if quitting the app doesn't work.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

No it's not stealing. They have an allowance that you can share with so many computers/devices. You'll have to authorize her computer to play/use anything bought on your acct. You can do this under the Store menu at top when iTunes is open on her computer.
As far as getting it all on her computer....I think but I am not sure (because I don't use the feature) but I think if you turn on Home Sharing in iTunes it may copy the music to her computer. I don't know maybe it just streams it. If nothing else you can sign into your acct on her computer and download it all to her computer from the cloud. Not sure exactly how to go about that, I haven't had to do that yet. I wonder if once you authorize her computer and then set it up for automatic downloads (under Edit>Preferences>Store) if everything would download. Sorry I'm not much help on that.

I want to know how to get the web addresses to go away that appear in the bottom left corner of the browser every time my mouse goes over a link

Any time that my mouse goes over a link on a web page a little box in the bottom left corner of the browser pops up showing the web address for that link and it is really annoying, especially when i am on facebook because there are so many links on the home page i cant move my mouse anywhere without that box popping up and blocking part of my conversations. I was wondering if there was any way to turn this off. I've checked through the options and to my knowledge there is no way to turn it off. Just wondered if anyone else has had this problem or knew if there was a way to get that box to go away.

Another option would be to use the following extension to push those messages into the status bar. It could be a convenient way to have your messages visible when you want them, but with less distraction.

Trashing the preference file may help, as I've outlined in the topic I've linked to. Otherwise, follow the steps regarding removing 3rd party QuickTime components. Also, see the final post by the OP (EEye87) regarding how his problem was resolved (a combination of trashing the preference file and the 3ivx component).

Since Yosemite, my iMac keeps going to sleep roughly every 10 minutes watching media

Since upgrading to Yosemite my trusty old iMac (mid 2007) keeps going to sleep roughly every 10 minutes whenever i'm watching media (either through a player or streaming online), regardless of power saving preferences. Everything else is working perfectly as it always has, as far as I can tell.
What am I missing? Are there new settings in Yosemite for this?

In addition to resetting the SMC as Link suggests.
You should also check and/or clean-vacuum the dust out of your iMac's air intakes to make sure that it is cooling properly.

My iMac keeps going to sleep

This started happening about a week ago. I have the Energy Saver "Put the computer to sleep when it is inactive for:" set to "Never". Also I keep the computer up 24/7 and it doesn't happen over night. But lately this is happened a few times. Yesterday, my wife called me at work and told me that "the screen was black" I asked if the light was pulsating on the front of the mac, it was. Tonight after work I was ripping a CD. I had dinner and went to the computer and it was asleep. I mentioned it to my wife and she told me it happened twice today.
Is it possible that some key sequence or something is putting it to sleep? Of course, I didn't touch it and it went to sleep. Is this a possible hardware issue? I still have the extended warranty (at home service). Should I have it looked at? Its not a huge deal, but I have it configured to never put it to sleep (I do how the "display" sleep after 2 hours of inactivity though.
Hope someone might have a suggestion.
Thanks.

If you still have AppleCare or it's covered under onf the G5 iMac extentions, and it turns out to be that... I sure think so.
Try some heavy lifting CPU wise with it, like making a big disk Image or burning one like before.
I don't remember the exact temp figures, but tyours does see high, iirc.
Looks like it is too high...

IMac keeps going to sleep

Hi there.
I bought a second hand Rev. A G5 2 months ago. It has always been noisy - loud fan and a whiny noise. It's a bit annoying but I can live with it.
My major problem is the computer falls asleep by itself. It's unpredictable when it will happen but it does seem worse when it's been turned on for a few hours. It will wake fine once it's gone to sleep but will usually go back to sleep a couple of minutes later. I usually leave it for an hour or so and then it's okay. I have wondered if the noisy fan is linked to this. Is the computer overheating all the time? I tried resetting the SMU but that didn't really work.
Yesterday trying to import into iMovie was near impossible as it would keep sleeping - and the main reason for switching was because I liked the idea of iLife and using it to make DVDs of our old home movies and photos.
I'd like to get this sorted as I love my Mac (my friends say I've become obsessed!) but it's starting to get to me. I've read lots of posts about similar problems but there doesn't seem to be a solution mentioned.
Please help!

Hi
My kid's Rev A falls within these serial numbers but Apple refused to believe there was anything wrong and sent it back to my dealer untouched! The CPU fan constantly sits at a noisy 5600 rpm and the machine goes to sleep frequently during processor-intensive Flash games on the internet.
It's now back with my dealer in the hope he can convince Apple to fix it - although I am convinced the problem only started when I loaded Tiger - it ran quietly on Panther.
Having owned more Macs than I care to remember (and with a beige G3 still running 24/7 as a server in my office) - I really think this is software related rather than hardware. Apple kit has always been pretty reliable!
Hopefully soon I will know one way or another!

Intel imac keeps going funny

Spotlight has been playing up for days now. When i click on the icon nothing happens. If i restart sometimes that fixes it. Any ideas anyone.

Perform Disk Repair. Boot from the grey-labeled install disc 1 that originally came with your iMac. On the second screen find the "Utilities" pull-down at the top and open Disk Utility. Select (highlight) your entire internal hard drive, the "First Aid" panel, and then click the "Repair Disk" button and allow it to run to completion. Re-run until it reports "No repairs necessary." Quit Disk Utility and restart to your usual start up disk. Eject the dvd.

When trying to log back from sleep mode, the screen behaves as a rotating cube, with the mouse pointer in the top left corner. Hangs.

iMac OS X Ver 10.7.3
21.5 Inch, Mid 2011
2.5 FHz intel Core 5
12 GB 1333 MHz DDR3
When the computer in woken from sleep mode we see two login options (bineg used by two users).
But when we try to login, the screen just behaves as a sluggish rotating cube.
Nothing works, we just have to hard boot at this time.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

I have bought a second hand 3gs on O2 which was working fine and since restoring it (which put ios5 on) it now keeps saying no sim and has searching in the top left corner which then says no service once itunes asks for a sim to be inserted to activate?

I bought an iphone 3gs on o2 which was working fine till i restored it (which put ios5 on to it) now it wont activate, it keeps saying on itunes no sim inserted and on the iphone it has searching then says no service! Any ideas what i can do as cant get any further!

Some SIM cards were affected by iOS updates. Either contact O2 to get a replacement SIM or pop into a local phone shop and pick up a replacement SIM.
Once you have your new SIM, O2 have a swap my SIM page on their web site here:
http://swapmysim.o2.co.uk/
Follow the instructions on the O2 page and you should be up and running.
O2 do say it can take up to 24 hrs for SIM to be active, but I found it usually only takes half an hour or so before the new SIM is active.
Hope this helps.

Everytime i type anything or open up the firefox menu in the top left corner firefox goes black or stops working in some way how do i fix this? i have no addons

sometimes when it types if the auto fill address pops up its black and if i backspace the letters stay and if i type something the new letters overlap the old ones. I can open a new tab or get to my home website but i cant type anything without it messing up and i cant open any menus or dropdowns in the actual browser without it going black and reverting to the windows theme i have set.

You can try to disable hardware acceleration in Firefox.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need close and restart Firefox after toggling this setting.

I have notice that the top left corner of my Imac is getting warm/hot on the back

just curious if this is normal?

Yes it's normal, that is where the exhaust port is located. However you can always download and install iStat Pro and then post actual temperatures. Then post the temps and we can tell for if it's OK.
Your question is very common with many new owners and in almost 100% of the cases there is no need to worry.
