5s stuck in loop of apple screen bright blue screen black screen

My 5s went into a loop of the white screen with apple logo for about 10-15 seconds, followed by a quick bright blue blank screen, then a quick black blank screen, then repeat. I have turned the phone off (holding home and power button for 15 seconds). Tried connecting with iTunes unsuccessfully. Tried connecting USB and turning on. Same loop. I was not turning the phone off or on when this began. Have a genius bar appointment scheduled, but I would love to have some background knowledge of what is going on. I don't know what version of IOS I am running, but I know it was updated to latest version in early July.

leave it alone for sometime and once the status bar is filled up find out what happens next. is the phone giving a display or not and take it from there

Mac stuck on the grey apple screen startup? Follow these steps to re-boot....

So today I had a little scare with my Macbook. It was stuck on the grey apple startup screen with the loading icon. Switching it on and off did nothing and neither did waiting. I did a lot of browsing to try and find a solution but all the forums ended in 'looks like thats the end of my mac' or 'I think i've lost everything' or 're-install Os' blah blah etc. I DID NOT WANT TO LOSE ANYTHING!!! and I'm guessing neither do you! Ok so enough talking, in the end I found a solution which worked perfectly for me and I did not lose anything!!!!!:
Step 1
If the Mac is on switch it off.
Once it is off, switch it on again but this time as soon as you press the power button to switch it on, hold down the Apple cmd key + S.
Hold this down untill the 'safe boot' screen appears.
A black screen with white writing should now come up.
Step 2
Once the screen has loaded, at the bottom type:
/sbin/mount -uw /
[press enter]
then type:
chmod 775 /
[press enter]
then type:
exit
this re-boots the mac. As soon as you have done this the mac should load up again as normal!! Voila!!!
Hope it helps!

Someone suggested this to be risky. worked for me but DON'T DO IT WITHOUT RESEARCHING FIRST and if in doubt CALL APPLE!!!!!

On Startup, Stuck at the Gray Apple Screen & No Bootup

I used my powerbook last night and shut it down. Upon getting to work and turning it on, I haven't been able to get past the Gray Apple logo screen and loading dial.
I've been on several different boards and one gave me the steps to restart w/ the OSX install disk and hold "c". This worked, got me to the disk utility tool and I was successful in running a verification and repair. Here's the list of info it gave me:
Verify and Repair volume "Core HD"
Checking Journaled HFS Plus Volume
Checking Extents Overflow File
Checking Catalog File
Checking Multi-Linked Files
Checking Hierarchy
Checking Extended Attributes File
Checking Volume Bitmap
Checking Volume Information
The volume Core HD appears to be ok (in green letters)
So, from that, it "appears" to be ok, but I tried to do a restart from this area booting from the Core HD that contains my working content and I go right back to the gray loading screen.
_Any other advice before I take it to the Apple Genius Bar?_
_Possible issues to look for or tricks to try out?_
==========================
*Back info:* My battery has been going out lately and I noticed for the past week that I have to have my powersupply plugged into the powerbook in order to run (battery isn't keeping juice). So when I've had to disconnect the power supply to put the powerbook in my computer bag, the system shuts down and I have to restart w/ the power supply in.
_Could this have screwed up my HD or anything else?_
Thanks for any help in advance!

*: SUCCESSFUL UPDATE! :*
So, I tried it all w/o success at home, but was optimistic since I could still see my files when running the disk utility.
I went to the Apple Store near my house and I explained the situation to the Mac Genius guy. Again, he was able to boot from another disk, but still not my internal disk.
Final Determination: Corrupted OS & the need to Archive & Reinstall OSX 10.5
*Result = SUCCESS!*
He said, that the OS must have gotten corrupted by way of an update that didn't fully take or a newly installed program that may have disrupted the system.
So, we reinstalled (took about an hour and some change), I got to play with all the new Apple toys and got access to my desktop again all for free. No charge and of course the customer service was friendly and accommodating.
So, I guess the stuck gray screen w/ apple logo could always mean a couple of things, but if the data is still there and you've run through all other options, you can always try an archive and reinstall. Worked for me and I'm posting this message from my operable Powerbook now.
Thanks for the helpful advice TJK. And thanks for sharing your experience Wim138. Hope this helps anyone experiencing the same issue.

Mac mini stuck at grey apple screen

I was in the process of streaming some music through itunes from a samba share when my mini locked up hard and I was forced to do a hard reboot, upon startup now the mini is always stuck at the grey apple screen.
I hear no startup sounds other then the disk firing up (no welcoming chime) and from what I've tried, the system seems unresponsive to startup options (ie. holding shift, command v etc.).
I tried the obvious and disconnected everything and tried to restart but had no luck. Has anyone else been able to revive a bricked (bricked from what?? ) mini?

Hi All, I am sharing the same problem.
I have a Intel Mini, last night woke it up and clicked on itunes, the arrow swithced to the pinwheel.
Clicked on itunes and it said the "application was not responding" tried to force quit and nothing happened except for the pin wheel, I was able to get the computer to restart, well that process froze up too.
I did a hard reboot and the gray screen came on with no dark grey apple. Shut it down from behind the mini, went on with other thing, came back turned it on from behind again, this time I got the grey apple and grey pin wheel but it didnt go any further.
I checked out this post, restarted the computer while holding down the "C" key with the leapord disk.
Went in to disk utility clicked repair disk, message said the disk couldnt be verified/repaired. I then went to the sartup menu and shut down.
Any idea someone could tell me what to do next?

MacBook stuck at grey apple screen with spinning logo

I have a 2010 White MacBook that is stuck at the grey apple screen with a spinning logo. This seems to have happened after I installed the newest version of iTunes. The system slowed down a lot and when I ran the system monitor It said all of the memory was being used up. I had to force shut down by holding the power key. Upon reboot, I got the grey apple logo screen, a spinning wheel, and a progress bar. The progress bar gets about a quarter of the way and disappears. The spinning wheel remains. Initially, I let it run for awhile. Nothing different happened. I took off the Mac jack adaptor, and replaced the battery. Nothing happened. I kept trying to start it up and one time it worked. I backed up my files to two external hds via time machine.
Upon the next boot, i have been stuck at the grey apple logo screen, spinning wheel, and progress bar. Each time the progress bar remains and then disappears after going about a quarter of the way. I have tried cmd-D, cmd-s,cmd-opt-p-r, cmd-v but I don't think any of those work (I don't know of i'm doing them right) . It just stays on the grey apple logo screen. I tried using the option button at the startup and it goes to a lock screen. I typed in the administrator name. That didn't work. I tried the apple password. That didn't work. I tried every password that I know. None work.
What can I do to fix this?
Thank you.

See if this Apple note will help. When it gets to Disk Utility, boot holding the command and r keys down so you get into recovery mode, and run Disk Utility from there. Assume you have OS X 10.7 or later. If you're still on OS X 10.6, then follow directions to boot off the OS X DVD sent with your system or a retail OS X 10.6 DVD.

Airport Extreme card installed, eMac stuck on gray Apple screen at start-up

I just installed an Airport Extreme card on my eMac (USB 2.0). When I try to boot, it gets stuck on the gray Apple screen, with the spinning gray "spokes." The card is pushed as far as it will go into the slot, and the antenna is all the way in as well. When I take the card out, the computer boots up fine. I tried installing the software first, but it doesn't appear to be installed after it does the required restart for new software. I'm not sure if I have the software already...
At any rate, the biggest issue is that it won't boot past the gray screen. Any thoughts? (I have a version of Tiger, though I'm not sure exactly which because I'm sick of the un/install process at the moment, and am staring at the gray screen.)

Hi, I have a 1GHz eMac ATI and had a problem installing my Airport Extreme card as well. It would boot fine, but the card would not connect. It turned out that the card was not seated properly and maybe this is something for you to look at.
If you look at the Airport slot with the card and cover removed you will see the end of a black plastic guide bar on the right of the slot when viewed from the front of the machine. (Assuming the ATI eMac and USB 2.0 are the same in this regard) When the card and the aerial are fully seated home, the silver top of the aerial plug should be just about level with the front end of the black plastic bar, just a whisker or 2 sticking out. If it is more than this (more than say 1-2mm - 1/16th inch) then your card is not far enough in to be connected properly. Believe me I found this out through trial and error and there is not much difference between the right position and not.
It is not just a matter of pushing harder, you need to wiggle it slightly up and down and push firmly with 2 fingers, one on each side so that the force is evenly distributed. Mine needed just a smidgeon more force than what it took to slide the machine back - try it a little bit at a time. Put it up against a wall so it doesn't slide back, but don't apply excessive force. Part of the problem is that is hard to get your fingers in there to do the job.
Hope this helps.

MacBook Pro (late 2011) stuck at white Apple screen.

Hi all. My MacBook Pro 13 inch (late 2011) is giving me the same problem over and over again.
Few months ago, I had sent it to Apple for repair due to faulty HDD. Now the same problem happened again. The MacBook will stuck at the white Apple screen with the circle turning when attempting to switch on.
However, Apple had just replace a new HDD and why it's still happening again?
Can anybody here please assist to advice me what is making my Mac unable to start up, stuck at the white Apple screen, even after replacing a new HDD?
Thank you!

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 boot failure is to secure your 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 your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into 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, boot 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
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.
When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your 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 reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Screen stuck on grey apple screen with a loading sign

I thought i had lost my charger and i wasnt willing to fork out the money to buy one for awhile. During a recent move i found it. I charged it up but when i got to my login screen i kept trying to type my password and it wouldnt except it. After looking online i found several posts about click buttons i dont remember what exactly i clicked but it was along the lines of " option and the R key" Another screen popped up and it had several options one of which was to try to do a back up/ restore it through timemachine. I treid that and it wasnt working. I went back to the screen and saw an option that said install the lion thing. i tried that and it didnt work. I was frustrated so i decided it would be best to just shut down my computer and try again when i was less riled up. Well now it has been stuck on the grey apple screen with a loading sign under it for atleast a day now if not longer. I have no idea what to do. I'm not sure if i have apple care or not. Oh and not really sure what operating system i was using.

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Stuck on Apple screen at startup, details inside...

So here's what I did before the problem started... I changed the permissions of my HD to give my user "Read & Write", my system "Read & Write", my admin "Read & Write", and everyone "Read". I then applied these changes to everything enclosed in the HD. After this process I restarted my computer and it was stuck on the gray Apple screen.

The first thing you might want to try is to boot into single-user mode. At the startup chime, hold down the "command" and "s" keys. This will bring you into a command line interface.
If you get that far, follow the on-screen instructions for disk repair.
If that succeeds, try this command:
/usr/sbin/diskutil repairPermissions /
If you are really lucky, that'll fix it.
If it wouldn't get into single-user mode, try booting from the installation DVD, and then go to Utilities -> Terminal. At that command prompt, do a "df" command to find your internal HD. Then run the diskutil command above, but replace the "/" with the internal HD designation. That may save you from an Archive and Install.
Good luck.

Stuck on apple screen

Hello
I am having a problem with my iphone after I updated to ios7, my phone is stuck on the white apple screen when it powers up. I tried holding the power button, nothing happens.
Please help
-4s user

So, the ipod seemed to update.
I had it plugged in to my pc before I realized that it was mac formatted and the pc saw the ipod as a drive that wasn't formatted and the ipod just sat on the do not disconnect page.
I had no choice but to disconnect it and uninstall itunes then reconnect it and reinstall itunes.
At that point I was prompted to restore the ipod and I did, and I got the ipod to show some progress on its screen but then it just put the apple up and has stayed there ever since.
It (ipod) has been disconnected for hours, still the apple logo.
Any ideas?

Iphone 6 is stuck on apple screen with loading bar. It has been like for 12 hours.

My Iphone 6 is stuck on the opening apple screen with loading bar. It has been like this for 12 hours. I've tried resetting it by pressing the home and power button together but it keeps coming back to the same screen. What should I do?

I've had the same problem but it's tuck on like the very last little bit and hasn't gone anywhere in 10-15 hours.

Stuck on grey Apple screen, how can I erase and restore back to original?

I've been trying to restore my imac G4 flat panel back to its factory settings, as I have recently backed up my necessary files on an external hard drive. It came with Panther and I upgraded to Tiger, but now I don't have any of the disks. I don't care if it restores back to Panther, I just want to erase and restore it. I tried to download and mount the restore disc and do it from there, but now its stuck on the grey apple screen. Any help would be appreciated.

Hi Jared, and a warm welcome to the forums!
I tried to download and mount the restore disc and do it from there, but now its stuck on the grey apple screen.
Can you explain what that is, I've never heard of it being downloadable!>

Stuck on grey apple screen at boot up

Mac Mini Intel Core 2 Duo 1.83GHz, no hardware changes since purhcased, a year and 4 months ago. OS 10.5.6. Today it decided to croak. When I tried to restart, it got stuck on the grey apple screen. I did the following:
• Reset PRAM
• Reset SMU (I even tried the PMU reset, which results in the fan spinning at max speed)
• Tried booting up from DVD
• Tried booting up from external firewire drive
• Set it in target mode and verified via firewire that the internal drive is working fine (I checked it with Disk Utility with no errors found and even booted up from it). In this mode even the DVD in the Mini's drive showed up on the other computer's desktop.
• Reseated the RAM
• Replaced the RAM
Is it the motherboard? In which case, this will be an excellent door stopper... Thanks for any help.

I'm concerned, with you creating and using all the discs. Only the right one is supposed to be used, refer to http://support.apple.com/kb/HT1237
Boot ROM Version: MM11.0055.B08
SMC Version (system): 1.3f4
Based on your computer description, the Correct RESTORE CD appears to be V1.3 or 1.7. the applicability is at the bottom of the page.
http://support.apple.com/downloads/FirmwareRestoration_CD_17
Follow instructions
http://support.apple.com/kb/HT2213
You might want to try 1.7 again. If you don't get a complete code, your computer could already be at the correct firmware status. I'm am not familiar with any other reasons for why it would provide an incomplete installation. My guess is the software checks the Boot Rom and SMC version and stops, if it sees the right version. My computer reacted similarly when I upgraded recently. Now that is working, I can see the Boot Rom and SMC version are correct. At the time I never got to a choice of where to startup. refer to previous posts.
Which means this firmware update doesn't solve the problem.
So back to basics:
After completing the Firmware update, did you try that trick with the remote to chose your startup device? Does it let you boot from CD? or HD?
Selecting start-up CD = grey screen
Selecting hard disc = greay screen
You reseated the RAM, Did you perform the hardware test? http://support.apple.com/kb/HT2341
Verify the RAM is available.
I know that my disk utilities CD said my HD was good, but when I ran it with my new Snow Leopard utility it said there was a problem that required reformatting. If you were considering upgrading, I would do it now.
My solution was the remote trick, but that doesn't appear to be working for you.
