I have started having trouble since i had to upgrade OS the latest in July 12.
http://support.apple.com/kb/TS2570 Follow this article and when it gets to the part where you go into disk utility using your install disc, you'll actually boot up holding down Command and R

nephew had mutliple tabs open and shut down the iMac by hitting the button on the back instead of closing everything corectly. Now the only screen i get is the white with apple logo and the loading circle icon. i have attempted restart and c key with disk in but cant even get a menu to come up. What can I attempt from home before having to haul this into the store?
wireless keyboard and mouse were working prior to safe mode attempt, i was able to eject disk. still waiting on the safe mode restart. I'm not sure what I should be looking for to confirm safe mode and what the screen should look like if successfully processing. it seems to be putting off a lot of heat. BRB

Hi, I am not able to reboot my Mac desktop.
When I switch on the Mac, I get a white screen with the Apple logo and the little rotating circle.
The system refuses to boot.
What can I do?
MarcusWe need to get you moved. This forum is for mini-tower Macs built between 1998 and 2005 and doesn;t get as much traffic ("eyeballs on the problem") as the forums for newer Macs.
Please do "About this Mac" from you Apple menu and tell us what that says for "processor" and Mac OS version. Looks like this:
or this for later Mac OS versions:
With that we can figure out which of the two iMac forums you need and get the Hosts to move your post. -

this usually means the software and hardware can't find each other for whatever reason the following article addresses this issue:
http://support.apple.com/kb/TS1440
can also do apple hardware test, following article on that:
http://support.apple.com/kb/HT1509
if you can't access the apple hardware test in the above article you can also do fsck command to check the hardware as well, following article tells how to do that:

hopefully one of these articles helps w/ resolution!! -
I did the back up as instructed... Installed a larger hard drive and followed the restore instructions... Now I get a white screen with a folder icon and blinking question mark. When trying to set startup with new drive I get a bless tool error... Help!!
If you have installed a new hard drive , you will need to have formatted it in Disk Utility correctly. This may explain your problem.
Boot into your 10.6 Install disk again at the top menubar > Utilities > select Disk utility and in there select your new hard drive, and select the tab Erase and choose to make the format as Mac OS Extended Journaled. When that is finished look in the main window to make sure that the partition map scheme says GUID Partition Table.
Now go to the Restore tab and reinstall from your backup. -
I updated Efi firmware, but force quit twitter to install. Now system won't come on, it just shows grey screen with the spinning wheel loading. I am running lion 10.7.3.
Thank youThe following support article is somewhat outdated. Where it refers to booting from an installation disc, you should boot from your recovery partition (if running 10.7 or later) by holding down the key combination command-R at the chime.
Mac OS X: Gray screen appears during startup -
My MacBook Air will not turn on. I get a white screen with the apple logo and a spinning star (search icon). It will spin for hours and never go away unless I power off.
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. -
What do I do when I start my iMac I get a white screen with an apple and a moving circle?
All I get when my iMac is turned on is a white screen with an apple and a moving circle. What should I do to get the iMac to boot?
Do you have reliable backup you can restore from, as an erase and re-install may be required?
Before you got down that route, it's possible that it might get fixed if you try again. Not sure about that particular error, but I have had errors in the past that Disk Utility wouldn't fix on the first attempt but then subsequently did.
It's also possible that the (around $99, I think) Disk Warrior might resolve it - but not guaranteed.
However, I just found this thread: https://discussions.apple.com/thread/3862376?start=15&tstart=0 have a look at Nirvi's post at the end - there may be hope (I've not tried this, although it seems to have helped a few, although not everybody - so at your own risk and I wouldn't try it if I didn't have backup). -
Can't get my MacBook Pro to start up. Have shut it down several times and tried restarting but all I get is a grey screen with the spinning icon. Apple Support online suggested starting with power button followed immediately with the shift key. Same results. Also tried power button with shift key, command, and V. Black screen appeared instead with lots of data language but still no starting. This final page was suppose to result in an internal system check and restart but nothing happened and the black screen remains.Where do I go from here? Scheduled for the Genius Bar tomorrow but would like to resolve this beforehand.
You may be having a hardware problem that you cannot resolve on your own. Nevertheless...
...hold down the command and R keys whilst booting to try to get to your Recovery partition. If you can, use Disk Utility to try to Verify your boot drive (usually named "Macintosh HD" unless you've renamed it). If the verification fails, try to repair your hard drive. If everything appears to be OK, restart.
If you can't get into your Recovery partition, your problem is likely hardware related. If so, keep your appointment and see what the Apple techs have to say.

Non-booting Mac mini (stuck at gray screen with no Apple logo or others)
We've got a G4 Mac mini whose motherboard was recently replaced. I've put it back together carefully following the instructions on pbfixit.com, but I can't get it to boot.
When powered on, the chime sounds normal, and the screen comes on after a few seconds with a gray background--no Apple log, no spinner, no error, no flashing icons, nothing.
I've already zapped the PRAM 3 times using OptCmd+PR, no go.
I'm able to get into OpenFirmware using OptCmd+OF and have done reset-nvram and reset-all, restarting the machine, but no luck. The system date remains current also, indicating perhaps it's not resetting the PRAM either way somehow.
The disc drive won't accept a boot CD or DVD as if it's unpowered, but it's snugly connected.
I'm unsure what to test next. Suggestions? Thanks.Greetings,
I just had the exact same problem with a Mini. Would only boot to a gray screen no matter what I did. Booting into the OpenFirmware did help, booting into the Startup utility (by holding "T" down at startup showed no hard drive and no CD/DVD drive.
Hold on to your hat . . . .
The issue was the battery. These guys have a Lithium battery that allows them to boot up, a battery that can be purchased anywhere that sells those kinds of thing. I bought 2 for $3.50, it was more time and trouble to get into the case and get at the logic board but once the battery was replaced everything works like a dream.
Here is an excellent step-by-step tutorial about getting into the case http://www.sterpin.net/uk/ddMacMiniuk.htm. Just make sure that doing so doesn't void any warranties.
Good Luck!

my i phone 5 was dropped, didn't break but went completerly black screen and nonresponsive. I pushed both the home button and top button no response. I plugged it to the computer it gave me white screen with black apple. I pushed the home and the top went black then gave the itune and the charging plug picture. I tried to download and update, the message came as couldn't restore due to unknow error. Any help??
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

A few days ago my i mac when into grey screen; there were a few options for starting up, restoring etc i tried all of them to the extent possible but didn't work. Then i decided to unplug my external backup drive in case it may be erased or info lost in this process and now all i get when i turn it on is a white screen with a flashing folder and question mark. Any ideas?
That indicates the computer is having difficulty finding the startup volume. Your internal HD may have failed or the system may have "forgotten" where it is. If you are using Lion or later (10.7.x or later) then restart in the Recovery Partition and choose the startup disk. Before doing anything carefully read and follow Apple's instructions in:
A flashing question mark or globe appears when you start your Mac -
