Recently my pc crashed and I had to have a new profile built. Now when syncing my iphone 4s to the computer the sync gets stuck on step 8 and "syncing artwork" It never finishes syncing...just sits there for hours. Subsequently most of my music and apps are missing from my iphone because it never finishes syncing. How do I fix this?

1) ensure iTunes is authorized for your iTunes store account(s)
2) connect your device and right-click or control-click it in the iTunes Source list, then choose transfer purchases from the shortcut menu that appears.
3) sync the device
iTunes will wipe the iPhone but, since you transferred your purchases in the previous step, your content will be in your library and you can re-populate the iPhone with it.
above works for purchases from the iTunes store. for everything else, check out this post by Zevoneer.

My macbook pro 2011 shows grey screen with apple logo and want start

i was just using my macbook pro and it freezed for a while not responding and i turned it off by pressing the power button. afterwards, i turn it on and it shows a grey screen with apple logo but want start pls somebody help me because am having "my life" on the machine

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 Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. 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 by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. 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.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
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.

Computer won't start, grey screen with Apple logo only. Ideas?

Last night my wife's G5 froze. It is a G5 2.0 running OS X 10.4.11. I shut it down (had to use the power button) and tried to restart. No luck, just made it to the grey screen with Apple logo and spinning wheel. After a few seconds the Apple logo disappeared and a black box took its place, then the wheel stopped spinning. It was late, decided top wait until morning before trying again.
This morning I tried to start up again. This time got a warning(?) in upper left that a Firmtek item had already started. I'm sorry I didn't write this all down at the time, so I don't remember the entire message. Since there is a Firmtek card installed in one of the PCI slots I thought that might be the problem, and I pulled the card, as well as another Adaptec card that was also installed. Tried to start again, got to grey screen with Apple but this time no spinning wheel.
Opened media slot manually and inserted Diskwarrior. Tried to start with Diskwarrior but again only reached grey screen. Let run for ~5 minutes, until fans started to run and were begining to get noisy.
Next I reset the PRAM. No luck, still stuck on grey screen. Tried Diskwarrior again, this time got another message in upper left. Here is most of it -
System Failure : cpu=1; code=60000009 (Invalid pmap)
Lateset crash info for cpu1;
Exception state (sv=0x609bb280)
PC=0x000a4ad0; MSR=0x02003000 followed by more similar strings, then
backtrace terminated - unaligned frame address; 0xfc088891
So what's the diagnosis? I've had various issues with my G5s in the past, but have never had one refuse to boot with Diskwarrior before.
Thanks in advance for any help!

Whew, could be many things, from RAM, (or RAM slots/solder issue), to CPU #1 being bad, (CPU#1 is actually the second one.
Does it boot into any of these modes?

Grey screen with apple logo after new HDD install

I have a mid 2010 iMac A1312, this was given to me recently with the knowledge of its bad HDD, so I bought a new HDD. I followed step by step instructions on how to replace a Hard drive and I did. I switched the computer on and inserted my Snow Leopard 10.6.3 install disk and clicked the icon. It is now at a light grey screen with a dark Apple logo. I have waited about ten minutes and restarted the machine. Ive tried all variances of startup holding down c, option, command r and so forth. Currently I am going to give it a good long wait of 20 minutes or so and see if I was just being impatient and not allowing the install software chance to start up. But in the mean time... any suggestions? I have read I need the original disks that came with the computer from factory to get a new HDD going. Is this true? thank you for your time!

it has now been 30 minutes and no change. I still have the grey screen with apple logo. please help

I am curious as to why you repeated your question twice both in the subject box and in the discussion box?
In answer to your question, have you tried using
Disk Utility?
   1. Insert the Mac OS X Install disc that came with your computer, 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. (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. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Click Repair. Disk Utility checks and repairs the disk.
Then, if you can, reboot to your internal drive and repair permissions.

Stuck on grey screen with apple logo after failed iTunes update

I tried to install an update for iTunes 9.2 on my MacBook. During installation a box appeared telling me the update had failed. I clicked the 'Restart' button. Now it won't go past the grey screen with the apple logo and the rotating wheel; it just loads indefinitely. I have a very important document saved on the Mac which I've added to without backing it up. I'm worried that I will lose (or have already lost) a great deal of writing. Is there a way to get my computer running again without damaging my files? Because this computer was a gift, I don't have the software installation CDs that came with it (or Disk Utility). I'm also not very familiar with computers in general, so if you explain your solutions in a really basic way, I'd appreciate it. Any kind of advice would be extremely welcomed...

Resolve startup issues and perform disk maintenance with Disk Utility and fsck

Symptoms
If your computer won't start up normally, you may need to use a disk repair utility to fix the issue. Mac OS X includes two utilities for this—Disk Utility and fsck (a command-line utility). You can also use these even when your computer starts just fine but you want to check the disk for possible file system issues. For Mac OS X 10.4.3 or later, check out "About live verification in Mac OS X 10.4.3 or later," below.
Important: If you're using Mac OS X 10.4 or later, you should use Disk Utility instead of fsck, whenever possible.
In some situations, file system errors may prevent your computer from starting up. This can occur after an improper shutdown, forced restart, or power interruption. If your computer shows any of the following symptoms on startup, use a disk repair utility:
* Your computer partially starts but then displays a command line in a text-only environment. You may see the message, "file system dirty, run fsck." Below it, you'll see what's called a command-line prompt, indicated by a number sign (#), that allows you to type a command. If you see this, you'll need to run fsck from the command line (see "Use fsck if necessary," below).
* Your computer starts but either it won't reach the login screen, or it may reach the login screen but not load the Desktop after you log in. However, you can start up in single-user mode.
If your computer exhibits either of the above issues, here are some things to try to get your computer back to starting up properly again. If you can't find the system discs that came with your computer, see "Use fsck," below.
Products Affected
Mac OS X 10.4, Mac OS X 10.3, Mac OS X 10.2, Mac OS X 10.1
Resolution
Try a Safe Boot
If you're using Mac OS X 10.2 or later, you can start up your computer in Safe Mode, which includes an automatic disk check and repair. If you're using Mac OS X 10.1.5 or earlier, skip to the next section. A Safe Boot, which starts up your computer into Safe Mode, may allow you to start up your computer successfully using a reduced version of the system software. To do this, follow these steps:
1. Start up in Safe Mode.
2. After the system has fully started up, restart your computer again normally.
If the computer successfully restarts, you do not need to do any more troubleshooting. If the issue persists, try Disk Utility.
Try Disk Utility
1. Start from your Mac OS X Install disc: Insert the installation 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. (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. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Tip: Always start up your computer from an Install or Restore disc when using Disk Utility to verify or repair your startup volume. Otherwise, you might see some disk error messages.
Use fsck if necessary
fsck is a command-line utility that may be able to verify and repair a disk. If you can successfully start up in Safe Mode or use Disk Utility while started up from a disc, you don't need to use fsck. Here are some situations in which fsck may be necessary.
* Your Mac OS X disc isn't available.
* Your optical drive isn't available.
* You can't start with a Safe Boot by holding the Shift key during start up.
Tip: If you use a Mac OS X Extended (Journaled) formatted volume, such as with Mac OS X 10.3 or later, you probably won't need to use fsck. If you do use it for any reason, please be aware that benign error messages can appear.
If you're not sure how your volume is formatted and you can't start up from your Mac OS X volume to find out, type the following command in a command-line interface and then press Return: diskutil info /
If you see "File System: Journaled HFS+" returned, you have a Journaled volume.
To use fsck, you must run it from the command line. Unlike using your mouse pointer to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line.
Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt type:
/sbin/fsck -fy
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
** The volume (nameofvolume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
*** FILE SYSTEM WAS MODIFIED ***
Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
Your computer should start up normally and allow you to log in.
Additional Information
About live verification in Mac OS X 10.4.3 or later
In Mac OS X 10.4.3 or later, you can verify your Mac OS X volume while started from it. This is known as live verification, and can be used in three different ways.
Option 1: Verify your disk using Disk Utility while started from the startup disk. To find out how to do this, see this article. Please note that live verification does not involve any disk repair, so if verification finds something that should be repaired, start up from your Mac OS X Install disc and use Disk Utility as described above in "Try Disk Utility."
Option 2 (advanced): Use the command line and the command-line utility, diskutil.
1. Start up your computer and log in as an administrator.
2. Open Terminal (/Applications/Utilities).
3. At the prompt, type the following command and then press Return:
diskutil verify /
Note: Don't use this method to check non-startup volumes.
You should see messages such as the following during the disk check:
Could not unmount disk for verification, attempting live verify
Started verify/repair on volume disk0s3 Macintosh HD
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
The volume Macintosh HD appears to be OK.
Mounting Disk
Verify/repair finished on volume disk0s3 Macintosh HD
Option 3 (advanced): Use the command line and the fsck_hfs -l command.
1. Start up your computer and log in as an administrator.
2. Open Terminal (/Applications/Utilities).
3. At the prompt, type the following command and then press Return to determine your filesytem ID:
df -hl
4. Look for some lines of text that look like this:
Filesystem Size Used Avail Capacity Mounted on
/dev/disk0s3 37G 20G 17G 55% /
/dev/disk0s5 37G 37G 641M 98% /Volumes/Storage
5. Make a note of the first "disk" name that appears after /dev/, such as "disk0s3." This is your filesystem ID for your startup volume.
6. At the prompt, type the following command and then press Return:
df -hl
7. Then type the following command, where "disk0s3" is your filesystem ID you noted in step 4, then press Return:
sudo fsck_hfs -l /dev/disk0s3
8. When prompted, enter your admin password, then press Return to begin the verification.
9. You should see messages like these during the disk check:
** /dev/rdisk0s3 (NO WRITE)
** Root file system
** Checking HFS Plus volume.
** Checking Extents Overflow file.
** Checking Catalog file.
** Checking multi-linked files.
** Checking Catalog hierarchy.
** Checking Extended Attributes file.
** Checking volume bitmap.
** Checking volume information.
** The volume Macintosh HD appears to be OK.
Advanced information
If you're interested in UNIX-style command-line syntax, here's a look at how a couple of flags used above can influence fsck:
* The -y flag: Tells fsck that you want to answer "yes" to all questions about fixing, repairing, or salvaging information. This is the optimal approach, as answering "no" to any question causes fsck to stop. You cannot determine that all necessary repairs have been made until fsck completes and gives its final report.
* The -f flag: Forces fsck to check "clean" filesystems when preening.

* Handling "overlapped extent allocation" errors reported by Disk Utility or fsck
* Disk Utility reports "Underlying task reported failure" when repairing a volume

On start up: Grey Screen- No Apple Logos/Anything at all.

Hey there guys, looks like last night on my MacBook(Late 2007 Model) had a kernel panic, so I powered down due to the freeze. I had not done any software installs recently either. Turned the little guy back on to a grey screen with no logos, signs of life- just grey.
I've done a bit of reading online; tried doing shift on boot = no go.
Apple button on boot = no go
Option on boot = Brings up cursor but nothing else.
I don't have my discs on hand but I can if an OS fix is in need. I've also seen things online saying it's logic board related or HDD.
Any ideas?

Yea I had a similar issue with my macbook. I was using front row one night and when I woke up in the morning the screen would not brighten but I could see the background very dimly lit. So I restarted and then I got a grey screen... I called applecare and they did the normal t-shooting. When that didn't work I sent it to get fixed. I believe they replaced the logic board...

MacBook Pro failing to start up after fairly recent 10.8.4 update. Just grey screen with Apple logo displayed and then hangs.

After having to do a forced shut down (holding down power button) due to freezing I cannot again progress past the grey screen with the apple logo. The spinning cog comes on at first then disappears leaving just the apple logo (in case that is sognificant).
I have tried to find a solution through the support pages but have unfortunately been unsuccessful in my endeavours so do apologise I have overlooked the obvious and would really appreciate some help. I've just started the second year of my Uni and the timing couldn't be worse.
I have tried the following:
1) held down option and started in "recovery 10.8.4" from which I used disk utility to "repair disk", which at first needed some repairs and then I ran it again for the second time to confirm it had a clean bill of health.
2) I then ran "repair disk permissions" and repeated a second time to confirm it was all working well (however one error remained "warning: SUID file "system/library/CoreS... has been modified and will not be repaired" but have read that this should not be a big problem) After which I tried to start up again and it hung with the apple logo on the grey screen.
3) tried resetting the PRAM by holding down cmd+option+P+R before powering up, but it only chimes once and then restarts the mac, then chimes once and repeats the process again in and endless cycle.
4) I then tried 1 and 2 again and then tried to reinstall OSX 10.8.4 from the recovery mode, but this came up with the message "could not find installation information for this machine".
5) I tried starting up in safe mode by holding down shift after the chime at startup but safe mode did not start after leaving it 3 hours.
6) I tried starting in verbose mode with cmd+V but after running the script it reverts back to the grey screen.
I hope I have explained it in enough detail and appreciate any direction or thoughts as to it being salvageable and what to try next.
Many thanks

Eric
Thank you for taking the time to post those links to informative articles.
In relation to the first article entitled "Resolve startup issues and perform disk maintenance with Disk Utility and fsck"
I can confirm that i was not able to start in safe mode but was able to boot up in recovery mode and run disk utility. The only one i hadn't tried is fsck. Please correct me if I am wrong, but if from what I understand by the article, this is to be used if I could not run disk utility, with which I have been able to do and to repair both the disk and permissions. But again, if I've missed the obvious from that article please correct me.
Te second article entitled "Troubleshooting Startup and Login Items" identifies troubleshooting that should be carried out in safe mode. However I am unfortunately unable to start in safe mode and have not been able to progress past the apple logo since this problem started.
Thank you for both links and for taking the time to share. If though I have missed something more significant in this regard I would appreciate your feedback.
Many thanks

Powerbook won;t go past grey screen with apple logo on start up

Hi
I am getting very stressed, my powerbook g4 won;t go past the grey screen with the apple logo when switched on. I need to sort it ideally without another computer to go through but if that is necessary then I will do it. I have tried the RAM reboot but nothing, there is not even the spinning loading symbol just a grey screen - which it will stay on until I turn it off. Someone please help!!!!!!!!!!!!! Not sure of my OS as I can't turn my comp on, but I am running leopard on it

Welcome!
First, see if you can boot in Safe Mode, holding the Shift key during startup until you see a message about safe mode. Getting a desktop can take longer because Safe Mode forced some disk checking.s
...I am running leopard on it
Then you should have the install disks. They can be used to boot the computer for repair. Insert the DVD and press and hold the "c" key during startup. That will launch the installer BUT you don't want to reinstall yet. Find the install's Utilities menu and launch Disk Utility. From there you can check the hard drive and make some repairs.
I need to sort it ideally without another computer to go through but if that is necessary then I will do it
That would require that your compute work enough to start in FireWire Target Disk Mode. FWTDM lets your hard drive show up on another Mac as if it were an external drive. You can test by starting the computer and holding the "t" key until you get a blue screen with a big yellow FireWire symbol. Looks like this:

I believe FWTDM's code is in firmware and not on the hard drive , so may let yo uaccess the disk form another computer.

TS1367 My MacBook Pro will not go past the grey screen with apple logo in the middle

How do I fix this issue is there anything I can do

Hey there Gonzoeg850,
It sounds like you are unable to boot your computer to your desktop or log in screen. I do not know if you have tried these steps from the article you have up there, but that is exactly where I would start:
Troubleshooting: My computer won't turn on
http://support.apple.com/kb/TS1367
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).
Thank you for using Apple Support Communities.
All the very best,
Sterling

Re: My powerbook g4 15inch went lame after a long session of nonstop use.The mac osx froze up and I had to push the power button to restart.Now when I push power it makes the start up chime then goes to a grey screen (no apple logo).
