I try and start my imac and a grey screen appears with the apple logo and shuts down what is wrong?
my i mac just shuts down after apple logo appears what is wrong?
Your post only says iMac. We need to know what version of OSX you are running.
Did your computer come with Installation disks? If so, place the DVD in the DVD drive and reboot the computer while holding down "C" until the comuter boots.
Run Disk Utility on your hard drive and post back any messages you receive.

My mackbook pro suddenly freezed and when I swiched off and on again, a grey screen appeared with an apple logo then a loading circle underneath, and after a few hours, a blue screen appeared. What shall I do with this?
What operating system version, and do you have any backups of your data off the machine? TimeMachine? Option Key bootable clones? Storage? DVD's?
A reinstall of the operating system may be in order as a last resort, so if any of these steps on these links get you into the machine, make sure to backup your personal data (Music, Pictures, Documents, Movies) off the machine to a non-encrypted powered external drive regular storage drive (not TimeMachine as it might be corrupted too) and disconnect as soon as possible.
Good Luck and report back all what you tried.
Also report what change occured before this tragedy happened, was there a Software Update? A EFI firmware update? Etc.

TS3680 i cant start my imac computer... im stuck at the apple logo?
i cant start my imac computer... im stuck at the apple logo?
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.

There is always a blue screen appears after the Apple logo during the booting process. And then everything is back to normal. What is this thing? Is there something wrong with my screen or something?
Nah - that's just the normal boot process.

How old is this Mac? It is also possible that the hard drive has failed. If nothing works, take it to the Retail Store -
On start up of my new iMac it locks on the grey screen with the apple logo and the progress wheel spins. Boot up in safe and this is where it stopped at "BootCacheControl: Unable to open /var/db/bootcache.playlist: 2 no such file or directory. "
Reinstalling MacOS does NOT fix the problem for me. I'm still searching a solution !

On starting up my new iPhone 4s, it freezes on the apple logo. I have tried the reset buttons trick and have tried restoring again too but neither works. Any other ideas? Or is the phone simply corrupt in some way?
Did you try to connect in recovery mode and restore without using the latest backup?
Recovery mode and How to back up your data and set up as a new device
If setting up as new device does not work, you'll have to get it serviced or looked at by visiting an Apple Store.
Did you try to remove the ipsw firmware file and restore, to make iTunes download a new copy from Apple?
Those files are located here:
Rename, move, or delete the iOS software file (.ipsw)
iTunes uses "ipsw" files to restore your iPod or iPhone. If those files are unusable, then try deleting them, renaming them, or moving the file to a different directory. This will cause iTunes to download a new copy of the IPSW. When a restore issue is specific to a user, it is likely due to an unusable .ipsw file. If removing the .ipsw file does not resolve a user-specific restore issue, then the issue is caused by other user-specific security software settings or iTunes preferences. Creating a new user will also cause new .ipsw restore files to be downloaded in the new user. You can find the ".ipsw" files in these locations:
Mac OS X
iPhone
~/Library/iTunes/iPhone Software Updates
iPad
~/Library/iTunes/iPad Software Updates
iPod touch
~/Library/iTunes/iPod Software Updates
Note: The tilde "~" represents your Home directory.
Windows 7 and Vista
iPhone
C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates
iPad
C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPad Software Updates
iPod touch
C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPod Software Updates
Note: If you don't see the AppData folder, you may need to show hidden files.

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

When I started my Mac the screen was white with the Apple logo and power motion icon running. I attempted to turn off Mac then a message stating "Debugger called: <Button SCI>. Also "Waiting for remote debugger connection." What is my next step?
Hi , and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
And sorry to report that OSX is more Widows like than ever, but….
If that doesn't help Reinstall the OS. -
Refurbished iPod touch 3rd gen won't start. Just got it today to replace my broken one. It freezes at the screen with the apple logo, then flashes off and tries to restart again. Help!
I have tried holding the power home button but all that does is turn it off. When I try to start it again it goes into the same loop.

My Ipod touch is acting very annoying. When i press the sleep/wake button to turn it on it just turns on with the apple logo and stays there. The screen will then blink white occasionally and the process will start again. Once when it turned white. i pressed the power and home buttons at the same time and then the above process continued.
Sounds like your iPhones software may be corrupt. Try placing the iPhone into recovery mode. To do this, follow the steps in this article:

How do I fix a initializing problem with my macbook pro? I only get to the blank screen with the apple logo and the "processing something" sign... it just doesn't start the system....
Please help
MarceloIf there is no loading bar, it's usually a problem with a third party kext file in OS X itself.
You can press the power button down to force a hardware shutdown, then reboot holding the shift key down on a wired or built in keyboard, this will disable them and you go around and update your third party software.
Gray, Blue or White screen at boot, w/spinner/progress bar
Also take this time to backup your users files off the machine if possible.
Most commonly used backup methods
Sometime that won't work and you need to do more

I get a gray screen with the apple logo at start up and the trackpad doesn't work
My MacBook Pro has run fine until yesterday. It froze and wouldn't receive commands from the trackpad. I was still able to move the cursor but clicking or tapping the screen did nothing. I tried restarting but got the gray screen with the Apple logo and the spinning wheel. To get pass this I have tried resetting the NVRAM/PRAM and performing the safe boot. I also tried using the Disk Utility at start up but since I can't use the trackpad it was unsuccesful. I got pass the gray screen once performing the safe boot and restarted and everything run fine (including the trackpad) for about 20 minutes before freezing again. Now I'm back at the gray screen again and can't seem to get pass it again.
Any advice what should I do next?I would back up the files and start looking at the HDD. Open DISK UTILITY>FIRSTAID.

My MacBook Pro will not start. When I started it goes to a gray screen with the Apple logo and has the spinning dial. When I started in safe mode it will not start. In safe mode it as an error message that says MacBook Launch_msg(): Socket is not connected
If running 10.7 or later hold down Command-R at Startup.
This should invoke recovery Mode.
Choose Disk Utility.
Select your Hard drive. Inspect the SMART Status in the lower right of the window for "Verified".
Select the Mac OS X Volume (originally Macintosh HD) click (Repair Disk)
If errors, run again until it comes clean or gets stuck.
Report any error messages.
