My iphone 5 suddenly wont fully boot...it stuck on the apple logo and goes of after 20 -25 secs and comes on by itself after a minute or two but still stuck on apple logo..also i am able to see a bit of lighting on the dark screen whenever it goes of

my iphone 5 on the ios 7.1.2 suddenly wont fully turn on...it gets stuck on the apple logo and stays like that for approximately to 90 secs then goes blank but I can see a bit of lighting behind the dark screen....it goes off by itself and comes on by itself trying to boot but still gets stuck on the apple logo after the dim light shows....when I connect to iTunes my phone can only be recognised only in recovery mode thus if I force it into recovery mode. My main worry is I don't have a back up of any of my data...on icloud I have just less than 2GB of my data which is as a result of incomplete back up...HOW CAN I GET THIS PHONE WORKING AGAIN WITHOUT LOSING MY DATA...if I can only just recover my data I would really appreciate it as I really need almost everything on it back...if I can only get retrieve my data and lose the phone I wouldn't mind at all....Anybody know how to resolve this??Kind Regards

Anyone have any suggestions? or is everyone else just as clueless as me !

TS2570 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 !

Imac will not boot up, chimes with apple logo and beach ball spin??

imac will not boot up, chimes with apple logo and beach ball spin?? after installing adobe flash and up graded apple softeware

If your iMac came with or is running Lion, startup holding either the Command-R keys or the Option key and select the recovery partition and then use Disk Utility to repair the Macintosh HD.
see > OS X Lion: About Lion Recovery
If your running Snow Leopard or earlier OS X, pop in your Install DVD and startup holding either the Option or C key, then open and use Disk Utility to repair the Macintosh HD.

Got a iMac upon start up it has white screen with apple logo and loading wheel spinning forever under it, does anybody know how to fix this?

PLEASE HELP!!!!!! EMERGENCY Upon start up normal start up noise occurs, then after white screen with Grey Apple logo, and a spinning loading wheel under it (thee repetitive lines NOT rainbow one) ?!? then thats as far as it goes it stays on that screen forever will not boot up. Any info on how to possibly fix? I've tried several of the Start up shortcuts , it wont even start up in Safe Mode . My fiance' is crushed she is a writer and EVERYTHING SHE HAS WORKED ON is somewhere on that hard drive. Any thoughts, i'm open to any and all LOGICAL responses, thank you very much for ya'lls time ........Its just heartbreaking to see my iMac in this vegistated coma,The whole reason i bought a mac was cause I love them I have Apple EVERYTHING, so once again please help.

Try this: Switch off your iMac wait 10-15 seconds hold down the Option Key (alt) key then press the power botton but keep the option key down. This should show all the available options to boot from. I trust you have a full backup, Good luck.

I get a white screen with apple logo and progress bar on my imac mavericks

I get a white screen with apple logo and progress bar ,then computer shuts down
when I turn my imac back on same thing happens,every time same thing
pprogress bar only goes half way then computer shut down
is there a solution ?
if not is there a way to at least salvage some files and docs?
i Have the latest imac 27

Thanks I tried it but after I repaired my disk via disk utility at start up, it told me that
my disk can't be repaired and to try to back up my files so I can format it
but is there to back up my files?
also what I get is white screen with the progress bar not grey

IMac starts with sound but remains with Apple logo and the clock running indefinetely

After software upgrade ( from mavericks to new mavericks ) iMac doesn't start anymore. It remains always in the same mode: after the sound of start the Apple logo and the clock that runs indefinitely without the start of the software. Someone knows what to do?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
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.”
b. 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.
c. 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 either of the techniques in Steps 1b and 1c 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 you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
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, or if a firmware password is set, or if the startup volume is a Fusion Drive or 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 10. 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
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 10
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 11
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 12
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.

Just wondering what Apple's stand is on the issue with a flickering and a dark area appearing on imac 27"screen - forums seem to indicate this is not uncommon - and happens through normal use - so should be subject to repair (Sale of Goods Act - 6 years)

Just wondering what Apple's stand is on the issue with a flickering and a dark area appearing on imac 27"screen - forums seem to indicate this is not uncommon - and happens through normal use - so should be subject to repair (Sale of Goods Act - ie 6 year warranty)

We are just users like yourself. If Apple has stated publicly about the problems you mentioned, it will be listed on their website and/or in one of their Knowledge Base Articles.
I have a 27" & do not suffer from such a problem. You should keep in mind that these are technical support forums. Generally, the only people posting here are those with problems. The thousands/millions without problems don't ever come here.
Think of these forums as a hospital emergency room.

My aunt just bought her phone ( iphone 5c ) but then when i tried entering the serial number on apple's site it shows as iphone 5s. I asked my aunt what's the color of her phone and she said it was green and it was iphone 5c. Could this be a fake iphone?

My aunt just bought her iphone (5c) for half of its original price here in Phils. So to check it was a
Egit one, i asked for the serial number by checking the settings of her phone. After geting the serial nu,ber, i entered it in apple's site to verify. I was kinda surprised since the phone that appeared was 5s instead of 5c. I asked my aunt what's the color of her phone and she said it's green. So could this be a fake iphone phone?

If the warranty is showing less than 12 months ,the iPhone has already been activated ,so yes most likely secondhand

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.
