My iMac Version 10.6.8 has problems starting up. I often get a white screen without the apple icon. Then I must turn the computer off and restart. Restarting will usually bring up the Apple icon and the start screen. What could be causing this? And how can I resolve this issue. My Mac is still under warranty, I've had it just 7 months.

Reset the NVRAM/PRAM and Reset the SMC.

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.

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.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

HT201177 My iMac won't fire up. It shows a white screen and the apple with little dial going around but won't complete start up

I rebooted my iMac this morning and now it won't come back on. It shows a white screen with the apple and a spinning wheel. Do I need to take it in?

More details needed, such as computer and OS. Step one is to restart—hold down the power button until it shuts off, push it again, and hold down the SHIFT key until it starts in Safe Mode. Report back.
As for taking it in, if this doesn't work, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

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).

My Iphoto version 8.1.2 stopped working today. Opens to a blank white screen with the little color wheel spinning indicating something running. I also cannot shut this window once opened without doing a hard shut down of my Mac Book Pro. What is wrong?

Opens to a blank screen with the little color wheel running indicating that something is running everytime I put my mouse on page. I also cannot close the page or do anything concerning this page when the little wheel is running. This has gone on for hours. I can only close the page by doing a hard shutdown of by Mac Book Pro. Never had this happen before.

Your main library is damaged.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

Try starting your computer by holding down the command + R keys, then run disk utility on your hard drive to verify/repair it. Take a look at his link, http://support.apple.com/kb/HT1782

I went away for a week and shut my MacBook Pro down. Since being back it has been super slow so I decided to restart it. Now it gets stuck at the white screen with the apple and spinning circle. HELP!!! I tried restarting over again and it didnt help.

Sometimes it will stay at the apple screen and sometimes it just shuts back off. The battery is fully charged.

I'm pretty sure it's mountain lion. Neither of your links worked tho, but thanks for trying! I'm new to Macs and only really know the basics of how to use it. When I power on and hold the option key I can chose to recover my Mac. What will that do? Will I lose pictures and stuff? I just went to Mexico and all my pics are on there and I'd hate to lose them, also lots of pics of my little boy.
Hmmmm, they are both working for me. What happened when you clicked on the links? Any error messages?

The Gray Apple appears only when it has been loaded from the boot device. Its failure to appear suggests the Boot device may be the problem.

My iMac won't get passed white screen, My iMac won't get passed white screen

Hi I was updating my iMac with mac os lion and it was installing the update when there was a power shortage and the iMac turned off. Now when I turn it on it won't get passed the white screen with the Apple logo and the turning thing, what should I do?
The update I was doing was the Mac OS X Update Combined version 10.7.3

I'll assume you have backups of your data. Boot from your recovery partition (command-R at startup) and reinstall the Mac OS. You don't need to erase the boot volume. If your Mac didn’t ship with Lion, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
