IMac can't get past grey screen...
This all happened when I was creating an Image of an OS 10.4 dmg file. as soon as it finished different items began disappearing from the top Finder bar. Soon as I restarted I couldn't get past the gray screen with spinning thingy.
Here's what I tried so far-without success:
_Zapped the PRAM (Option, Command, P, R keys held down on start-up); all peripherals had been disconnected.
_Reset the SMC controller by unplugging everything from the iMac for at least 15 seconds, and then powering back up with just the keyboard connected to it.
_Made a full hardware check holding down the "D" key with the MacOSX disc inserted upon start-up; the check turned out fine, no errors. no errors in my RAM chips either
_was able to successfully use Target Disk mode so I was able to back up my Hard Drive.
_Inserted the OS 10.4.7 Disc that came with the iMac, ran Disk Utility, selected my Hard Drive and ran a "Verify Disk" (said it had a error on the hard drive, so I then ran" Repair Disk" and told me it repaired whatever it needed to. (can't remember exactly what it said). booted it back up and still Gray Screen with spinning cycle
few things to note:
_It won't let me boot into safe mode. (when i hold Shift down the Apple comes up but I get a circle with a diagonal line going thru it (like the no-smoking sign) flashing back and forth between that and the Apple logo until I let go of the Shift key.
__booted by holding down option, was able to select my Hard Drive {(apparently it still recognizes my HD (i.e. M. Scorsese icon)} but still won't work
i've run out of ideas other than restoring and erasing everything.
I think you did a pretty thorough job of trouble-shooting.
I think the problem is related to the error you got running +Verify Disk+ in Disk Utility. +Repair Disk+ may have reported it being repaired, but probably not completely. Some critical system file(s) may have been damaged.
Take a look at this article.
http://support.apple.com/kb/TS1417
I think you have done everything listed already, except using fsck, so try that method.
If that does not work and you decide to reinstall everything, you may want to first try the +Archive and Install+ option in Installer. +Archive and Install+ will give you a fresh system while maintaining your user account and settings. Some third-party apps may need to be reinstalled. Since you have a backup already, you could decide to completely erase the drive, reinstall, and restore data, as the last resort.

Can't get past grey screen after update! Losing hope...
I've spent over a week trying to figure this out and about to give up... hoping that someone will reach out and try to help me resolve this. I'm seeing a lot of people with this problem, most go unsolved.
Downloaded and installed Mavericks from Mountain Lion on a Macbook Air 2012. After restart I get a grey screen (goes a little darker after a few seconds) with the Apple logo and nothing else. I can move the mouse though.
I've tried safe mode but the progress bar only goes 3/4 and then disappears and the grey screen and logo are all that remains.
Tried clearing PRAM and downloaded and installed at least 3 times now. Last time it stayed on saying that there was less than 1 minute left for over 10 minutes. Finally restarted... and brought up the grey screen with the logo and here it is 45 min later!
Ran the disk utility on the Mavericks drive... it showed that the Mavericks drive had no repairs needed and all permissions are in order.
I do not have a backup or time capsule, so I'd really like to try to not do a clean install.
Really hope some good hearted Appleton will help me so I can be all happy with my Mac again!Before proceeding further you should secure your data. You are close to losing it and the instructions below will make a copy of it without having to boot the operating system. The good news is it appears your system disk is reasonably healthy so this procedure should work. You will need an external drive which you will erase as part of this procedure.
Boot the recovery partition:
• Press the power button and as you hear the bong,
hold down the Command and R keys.
Once booted, click on Disk Utility.
Format (and erase) the destination recovery disk:
Plug in the drive you are about to erase.
Select the volume that is NOT your system disk.
Click on Partition.
Pull down under Partition Layout to 1 Partition.
Click on Options…
Select GUID Partition Table.
Name: Emergency Backup
Format: Select Mac OS Extended (journaled)
Click Apply.
Click Partition.
Make a copy of your system disk on the recovery disk:
Drag and drop the named system disk to Source (often called Macintosh HD):
Drag an drop Emergency Backup to Destination:
(Do not reverse these.)
Click Restore (the lower Restore button).
Be patient for it to do a full backup of your system disk.
Then try reinstalling Mavericks from the Recovery partition. -
I have a Macbook Pro 17" and i can't seem to make it past the grey screen with the waiting spiral. I have EXTREMELY important information on the hard drive. I need to get this information off of the hard drive. I have tried using a firewire attaching it to a G4 to try and access the information, and that was unsuccessful. I have also tried the archieve and install but it would not recognize the hard drive or any of the information. I have spoken to almost a dozen people and taken it to a computer store. PLEASE HELP ME!! i'm a photographer and it kills me to think of losing all my work.

Help I can't get past grey screen or reinstall osX
Hi I have an imac g5 without isight (non intel) and I tried to install the new osx update (this is thursday night). A pop up said the install failed and i tried to open a program, but it only bounced once on the dock and didn't open. When I tried to restart it, it froze on an empty backround so I manually turned it off. Now when I turn it on, I only get to the grey loading screen, then after a minute or two the fan turns on. I will not go past that no matter how long I let it sit.
I talked to the techguy at my school and he told me to archive reinstall it from the disc. When I try to do that, after installing the first disc of OSx (archive with preferences saved)It says the install was unsuccessful and to try again. I ran the hardware diognostic and it says there is nothing wrong with hardware. I dont know what to do. I'm going to try it again without preferences, but I absolutely cannot delete my hard drive. I am a film student and only a quarter of my stuff is backed up.
Please help, I could not afford the mac insurance renewall, I deffinately can't afford repairs or $49/hr apple help phonecalls. thank you."Disc repair was unsuccessful."
If it reported problems it could not repair then you may have directory damange/problems. Archive and Install is not going to solve this. The more you use your computer, the more damage you will cause your system if your directory is damaged.
You will need to purchased a stronger 3rd party utililty. The favorite around here is DiskWarrior followed by TechTool Pro. There are others.
You need to make your own decision on which to purchase. Read up on them on their websites because each does something a little different. -
Can't get past grey screen at start up (Late 2008 MBP)
Hi all, I have a late 2008, 15inch MacBook Pro. 2.4 GHz, with 4 GB DDR3 RAM, running Mavericks 10.9.2
Symptoms
my problems started after finally upgrading to Mavericks 2-3 months ago. Upon restarting after the install I could only get to the grey/white screen, then it would either freeze, or restart (with a 'your computer was started because of an error' screen). This would go in a cycle half a dozen or so times before eventually starting up, and everything would then work as usual. Now however, it will not start up. It will boot up in Safe Mode every time.
What I have tried
SMC Reset
NVRAM/PRAM reset
Have taken out additionally purchased RAM and tried booting without it
Tried booting without any peripherals plugged in
Repaired Disk with Disk Utility
Run Cleaning and Maintenance software with Onyx
Erased disk (after backing up of course) and tried clean install of OS X from USB (the DVD drive failed some time ago and as such I cannot boot from disc, nor can I conduct a Hardware Test.
I haven taken my machine to an Apple Certified retailer/repair outlet (there is no Apple Store near me anymore), at first they said they couldn't find the problem, then told me the hard drive had failed, which I'm pretty sure is not the case. The error message screen implies my problems may be due to kernel panics, which I don't really understand quite honestly.
I have spent a lot of time researching these issues on the internet and have come across many cases that are similar and have tried all the suggested fixes. The solutions in the cases that have been resolved have not worked for me either unfortunately.
I think that's everything. If anyone can help or has any suggestions for things I may not have tried, I'd be very grateful. I can provide a recent Crash Report if necessary.
Many thanksHey, thanks for taking the time to reply.
Here is the most recent panic report, minus the header.

Imac can't get past login screen ...New user problem..
Hi,

I must have done something while installing my Adobe CS2 suite software. The install hung on disk disk2. The entire machine locked up. I restarted and I now I get up the to Apple login screen but when I click on my user icon with the mouse nothing happens. The keyboard does not seem to respond either. I tried clicking on sleep, restart and shut down, but no reponse. I've powered down, unplugged and restarted ut still no luck. Can anyone tell me what I'm doing wrong? I like this PC but its so different from my Windows machine.
Thanks

My old iMac and OS 10.4 will not accept the New iTunes Version 10 application and I can't get past the screen offering to download iTunes 10. This is wrong and I need help getting past this situation. Help!
Sure, you can get around it if you don't need the newest version of iTunes. I still use version 7.5 because the newer versions didn't strike me as offering anything I needed.
If you do need a version 10-something then you will have to upgrade your operating system to Leopard (fi your computer will support it) at least. If you need 10.5 for some reason then there's no getting around it, you will have to buy a new computer. -

My iMac won't boot past grey screen and it didn't come with a os x disk
My iMac won't boot past grey screen with apple. I've tried booting in safemode but that didn't help and my iMac didn't come with a os x disk.
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. -
I recently installed iTunes on my new HP laptop computer, authorized it according to the instructions, but now can't get past a screen that tells me that I need to authorize the computer. I purchased an album and it's in the library, but it won't sync.

Macbook keeps restarting, can't get past icon screen
I had to correct my permissions because I couldn't edit my address book and ical. Everything was working fine last night after I did the permission fixes. But when I booted up my Mac tonight, the farthest I could get was the white screen with the Apple icon and the animated circle. After a few minutes, the laptop will reboot itself and continued to do that for 30 minutes. I can't get past that screen. What is going on? How do I fix this? I finally turned off the Mac and am using my Dell.
The question mark on the file tells you that your MacBook wants to start up but can't find a viable OS to start from. Can you start up from the DVD that came with your Mac? If so, go to Disk Utility and see if you can repair the internal hard drive. If you can't see the hard drive from within DU, your drive may have failed, and you may need to replace it. Good luck.
