IMAC motor revving up after I push the on/off button
I turned on my iMac and the sound of a motor going full speed has made me concerned. I have an iMac Processor 3.4 ghz Intel Core 17. I bought it three months ago. What shou.ld I do? OSX version 10.8.2.
Did it only happen when you started the computer? If the answer to that question is yes, you don't have to worry about that

I performed the steps indicated but this morning when I clicked the mouse and hit the space key and clicked the track pad again as before nothing happens.
I hold the power button for a few seconds and the screen fills as if the computer was normally awakened but it is locked up.
Then I have to shut it down with the power button and then power it up as a reboot.
Not good...SMC reset didn't work....Throughout the day yesterday I put the computer to sleep and woke it up normally. It seems to be a overnight problem.
Am I going to have to shut it down everynight?

I am getting a message in the middle of my imac screen instructing me to hold down the on-off button and turn off the computer. The message is in several languages and completely takes over the computer disabling the mouse and all other functions. The only option is to unplug the computer or turn it off. I'm concerned that this is a virus. It does not look like it's related to Apple or the imac OS.
That sounds like a kernel panic. These are generally hardware related, often caused by poorly seated or fauly RAM.

So my iMac crashed - just left normally with safari while I was listening to music on Pandora and suddenly the screen became full of fray lines and nothing could be seen or done. I then had to force it off by turning it off from the on/off button at the back. I then turned the Mac back on and it was working like normal. I turned it off that night.
My mum then turned it on and was playing spider solitaire like she always have. The same thing then happened to (while I was not around). She does not know much about computers and she couldn't turn it off after a while so she decided to then turn it off by unplugging it from the powerpoint/wall socket. It then would not turn back on.
Whenever I try to turn it on I can hear the usual clicking sound of the CD/DVD side, but nothing happens, it's just a blank screen.
What should I do? I've had this iMac for about 2.5 years almost 3 years now and this only happened last night.
Please help??Ok so it turned back on, and after leaving it on for less than 30 minutes and was not running any applications and it suddenly turned to a black screen and when I touched the back of it, it was completely boiling. Could it be that something is wrong with the fanning system? If I have purchased this iMac for almost 3 years already. Would I still be able to bring it out to the apple store and have it looked at?
Would I have to pay anything to have it fixed by the apple store? -
The right click menu pops up after I push the right mouse button, instead of when I release it.
I am using an extension All-In-One Gestures. It works on my other installation of Firefox 4 - particularly, the right-click menu pops up if I click right mouse button and then release it so I can perform gesture or turn the wheel instead of getting a right click menu.
But on this installation (basically the same addons and OS), the right-click menu pops up on pushing down the right mouse button so the right-button+wheel gestures do not work, and the menu stays there while I am performing the gesture which is rather annoying.
So I though maybe there is some obscure configuration option to toggle to make right-click menu pop up after the button release? Or is this entirely the extension's fault? Note that it does work as expected on other installation...You have to enable in Firefox
-> Options -> Content -> Activate JavaScript (yes) -> More
-> Allow scripts the following actions
-> Inactivate or replace context menu (yes)
in order to allow All-in-one-Gesture to block the immediate appearance of the context menu.
If you forbid Firefox JavaScript and/or the manipulation of the context menu by use of JavaScript, All-in-one-Gesture cannot work properly. -

My 6th gen nano ipod stopped working. I figured it was because it was next to my sweaty body, so put it in rice. I sought help from internet and tried all of the troubleshooting steps; i.e pushing down the power button and the volume down button consecutively, plugging it in to a power source, waiting 10 minutes and pushing the buttons while it was plugged in. Nothing has worked thus far. Is there anything else that I can try?

Iphone 5 went black. Tried pushing on/off and circle at the same time. Worked yesterday and then did it again today. Can't get it to work.
You need to hold those button longer until you see the apple logo, then release, then wait for the phone to boot back up.

Hello, I downloaded an ntfs systemfile from tuxera and used it to convert a usb stick so I could put more than the fat32 4gb on, my Imac froze a while after so I turned it off the on and now I have blue vertical lines on boot up and the a white screen with lots of tine blue symbols after, mouse pointer moves but thats about it.
Have used R and cmd to get a menu up but once I choose one of the four options my mouse is rendered useless and I cant get any further, have downloaded, to another usb stick recovery disk assisstant and am trying to use that in conjunction with the lion option on the previously mentioned screen, computer was responding really slowly and has now frozen on the terms of software license agreement (maybe the last hurdle!) can anyone pleeeeeease help!!!!!??????It's likely that the boot drive is failing, or that there's some other hardware fault. Run the Apple Hardware Test.

Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly. -
My MacBook Pro won't go beyond a white screen, after I pushed the restart button. How can I get it to a login? I have routinely backed it up, but don't know how to bring that up, nor if I have a boot file on that external disk. Help!
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -

I like to listen to lectures, etc. and find it very annoying to have to press the on/off button to restart it every 10 minutes. Couldn't find a way to extend playing time in settings. Any suggestions? This is my first iPod and I am ready to take it back if I am unable to extend the playing time. Frustrating!

I can imagine that is frustrating as heck. My daughter has one of these and I know for a fact hers does not turn off after 10 minutes because I have to turn it off for her every night after she has fallen asleep. Below is what Apple has to say about it from a troubleshooting standpoint.
"If music stops when the iPod nano screen turns off m Make sure the earphone port is free of debris. m Make sure the earphone or headphone connector is pushed in all the way. To see an illustration, go to support.apple.com/kb/ts3700."
Are you using aftermarket ear buds or speakers when you listen to these lectures??? If so maybe it has something to due with a compatibility issue. -
