MacBook won't start up it shows the apple logo and just keeps the "wheel" spinning

MacBook won't start up it shows the apple logo and just keeps the "wheel" spinning

Usually means that critical system files are corrupted. Start by:
Boot into Safe Mode if possible. If it boots into safe mode, then restart the computer to see if it will boot normally. Otherwise, reinstall OS X. Unfortunately, you've not provided any information in your profile about what version of OS X you have installed.

I Have iPhone 4S and Ipad mini w/ retina and updated both with the latest firmware of ios 7.1.2 during the 4th of July.

Early 2008 iMac won't start up. Goes to apple logo and freezes

Early 2008 iMac won't start up. Goes to the apple logo but it has a couple of yellowish stripes on it. Then the whole screen gets the stripes and it freezes. Does the same thing using another start up drive or a recovery drive. Running Maverics. Help!

I work at an Authorized Apple Reseller and we are having the same problem with one of our showfloor models.
Model: iMac 21.5" (Brand New Core i3, etc)
Problem Description: When you press the power button, you hear the Apple chime and the screen turns on. Instead of booting normally, the screen shows the Apple logo, a spinning 'loading' circle (I call it a ferris wheel), and a loading bar below that. Typically the loading bar is for an EFI Firmware update, but I don't remember updating the iMac recently. Anyways, the loading bar moves once, starts over, and then the iMac shuts down.
Possibly Related Issue: Several days leading up to this issue, the computer was very noisy. It sounded like the hard drive was working overtime on indexing or something, but it ran fine and spotlight wasn't even indexing at all. I walked by it yesterday and noticed it wasn't on. I pushed the power button, and the problem it has now started.
I will keep searching the forum for a solution, but I have a feeling this is a hardware issue that will need to be serviced by Apple.
Sidenote: If anyone has any experience contacting apple as an Apple Reseller about repairing a computer before the warranty starts, any advice would be greatly appreciated

My MacBook Air won't start it's grey with apple logo Howe do I fix this?

I have 2008 MacBook Air today I can't start up. When I press the power button it shows gray screen with apple logo and that thing spinning . How do I fix this?

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.

HELP please... iPhone won't start or turn off. Apple logo only

I try to reboot the phone w/by pressing the button on top and the button on the bottom of the face of the phone. The phone will go dark then come back w/just the apple logo... it goes no where else.
HELP

Known issue (better to say known quirk, not issue, however Apple should document it.) When you force boot the phone while it is loaded and running you corrupt some database and next boot will take a long time to rebuild this information. My 32GB 3Gs can take up to 7-8 minutes to boot as I have it full of music and I think it's rebuilding the music database during this long boot startup. The situation you are in now is that you have to wait for it to finish booting. The best way I have found if you phone is not stuck is to push top button until you get Red slider to turn off, slide it and allow phone to power off itself. Once off, Hold Top button and Home buttons, Keep holding them, you will see Apple logo pop up, KEEP HOLDING BUTTONS, do not release them until Apple logo goes away. If when you release both buttons the phone starts up and you see the Apple logo you have not held the buttons long enough as it sometimes will need to cycle down twice. When you have it right, when you release both buttons the screen will stay black and phone will not auto-power up. In this state the phone is fully off, not in standby. If you have previously powered the phone off gracefully with the top-button+swipe then hit top button for a couple of seconds and Apple logo should appear and phone should boot within a minute and be ready for use. If you cycled the phone without first gracefully shutting down, the bootup process can take much longer, give it at least 10 minutes before giving up. I have not found this documented by Apple anywhere, I found it from trial and error. My wife has 16GB 3Gs and while playing with both I found this out. Hope it helps you.

5S won't start up. Restarting after apple logo (infinite loop)

Hi,
My 5S had hardware problem and Apple renewd it. I would install my last backup to new 5S. After itunes copied +/- 50 apps the phone goes off. Now if i press the power button i see apple logo but the phone restart immediately again ang again until i press power button or battery goes empty.
Before restart itunes catch the phone but because it's restart itunes gives error message like ", can't recognize the iphone please plug in again".
What can i do not?
Thank you,

Hello
Usually this happens because of operating system file corruption from an improper shutdown. Your Macbook probably didn't enter safe-sleep when it ran out of battery.
You can probably fix your corrupt files by loading your OSX installation disk, and running disk utility.
Put your OSX disc into your macbook. If it doesn't boot into the disc, press down "Option" as you boot up.
Once the OSX installation process starts, keep clicking next/ok until you can see a menu bar on the top of the screen. Once you see the menu bar, click on it and select Disk Utility.
From there, you can check for errors and repair them.
When you're done, just select "shutdown" or "restart" from the menu. Don't proceed to re-install the OS!!
Good luck!

FYI Ipod Touch and Stuck on Apple Logo

I have found an issue where removing an application from the Ipod Touch which uses the Apple Ipod Settings GUI (The Icon with the picture of the gears) could cause your ipod to stick at the Apple Logo and force you to do a restore.
I had an application which I removed and noticed that I could no longer get fully into the Apple Settings GUI. It would freeze (it would never completely draw all the entries for the settings interface) for about 30 seconds and then take me back to the main interface. I thought I should restart the Ipod Touch and maybe that would clear up the issue. WRONG! I had to do a full restore in order to get back where I was. That took 6 hours.
Once I was back this time I tried to remove that application again and noticed the same issue. I opened the App Store on the Ipod Touch and searched for the application. I re-downloaded it and it installed. I was able to get back into settings and also restart with no issues.
In short, if you remove an application that has hooks into the Apple Settings interface. Always go into the settings after to verify you can still access it. If not reinstall the application and verify it works. Then report it to the developer.
I did contact the developer of the software and he said he would submit a bug report to Apple on this. I do not need to specify the dev at this time. I will just say be careful before you restart.

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 another cable
- 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.

Old iMac won't start up and stuck in grey screen with spinning wheel

Hi, I have a very old imac which I purchased back in 2005, and has been working fine. I have left it in storage about 1 and 1/2 years ago.
Just now I try to restart it, the screen is forever stuck in the grey screen with the spinning wheel.
I tried many times off-on, hold down the apple function key but none worked.
I no longer have the rebooting CD with me. I wonder whether the computer can still be saved?
I have already backed up the contents so it doesn't matter if fixing the computer requires me to delete all my old files.
Thanks
If I am not wrong, I think it's tiger or earlier that it's using.

Do you have the Install Disc to try to boot from?
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

Won't start up and has pattern on screen

Mac Pro running 10.6.8 won't start up and stalls out with just a funky pattern on a white screen. I have been able to do a Safe Boot and have run permissions tests/fixes but it still won't restart properly afterwards... arrggggh

Clone it to another drive, in part to NOT use the old system for now, and weed out any and all 3rd party background drivers extensions and processes. Or do a clean install, install as much as possible from original master copies/installers.
And move all the data and media to another drive. All but your home folder library so your boot drive is only the system and apps and that small 3GB user data.
