27" iMac stuck in Grey screen after startup

Hi everyone, I've read nearly all the posts on this subject. According to all the tips and suggestions I've done a SCM restart, I've run applejack and done an sbin/fsck -y rebuild, I've attached it to my Macbook pro via firewire in T mode and run disk utilities, I've also tried to startup from an install disc and got nowhere and I've done a PRAM rebuild. Still nothing. Someone thought it might be a Kernal panic?? Oddly enough I think it's a video card problem. as I have a second 27" Monitor and when I plug it in I normally get both screens go blue and then a second or two later I get both screens showing their respective images. This time I got nothing. not even the blue screen. I'm going nuts here. Does anyone have any ideas what the problems is???? Please help. oh and contrary to my listing, I'm running 10.8.1, not 10.6.8 ( I must fix that)

Mac stuck at grey screen after startup sound. Help

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.

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.

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.

MacBook Pro stuck at grey screen after Yosemite upgrade

upgraded to yosemite yesterday. Reboot and stuck at grey screen(login in page) when i log in there is some codes thing at the left top corner of the screen. and then it reboots again. Which means I can never log onto the computer. what should I do

If you can't start up and log in in the usual way, try in safe mode.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally 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.
Log in as an administrator to carry out these instructions. If you have only one account, you are the administrator.
☞ If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
Safe mode is slower than normal, and some things won’t work at all.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t start in safe mode.
If you're able to log in, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.

Stuck at grey screen after reboot

I seem to be stuck at the grey screen after a reboot of my server. Here are the symptoms and I'm wondering if anyone has experienced them before or has some idea of where to look:
1) Over the last couple of weeks, I've noticed the entire system freezing up for 10-20 seconds. The spinning pinwheel pops up and when my office is really quite, it sounds like either a fan is starting on the system or a hard drive is spinning up. Note that I've turned off all 'spin drives down when possible' in energy savings.
2) After the 10-20 seconds, a bunch of disk activity occurs and everything goes back to normal.
I've tried repairing permissions, checking for errors with the drive, etc. I've got two drives striped in Raid 0 (yes, the system is backed up--so I'm not worried about loosing data).
After a recent software update, I had to reboot it, and that's where it got stuck. Could be something there for some time, but my server usually runs for months at a time, unless an update requires a reboot.
Thanks for any help or suggestions!

Could you be more specific about what disks you used to boot with and exactly what programs you ran...
I cannot seem to get it to boot from the "Admin Tools" disk using the "D" key.
Also, when booting from the "Mac OS X Server" disk I can access Disk Utility, but do not see Raid Utility anywhwere.

Stuck on grey screen after restore

Ok, I thought I was a Mac power user until today with over 20 years using them, but I'm stumped.
I installed Lion and had the now-famous "lost user account" issue. So I "added" my old account and everything seemed ok. But when I tried to use Aperture, it couldn't find my library, which is one of the main things I use the Mac for. Not finding any solutions after quite a bit of Internet research, I reluctantly did a full restore (from 2 days before Lion was launched). The restore took literally all of yesterday. When I woke up, I was greeted with a notice saying that the restore had been successful. Great, right? Not so fast.
Since I hit restart, the machine has been stuck on the grey startup screen. (I'm typing this on my iPad)
I am about ready to break out my trusty copy of Disk Warrior, but before I do I thought I would ask the friendly folks here if you have any helpful suggestions so I don't make things worse. Thanks in advance for your thoughts.

Well, I got off the grey screen by doing a force shutdown and re-installing Snow Leopard, in case anyone else is having the same problem. I'm now in the process of verifying that everything that was on my machine is still functional before I contemplate "upgrading" to Lion again. Needless to say, I recommend regular backups. I've been doing so for a long time and have never needed the backup until now -- I'm glad I have it!

IMac stuck on blue screen on startup

I recently purchased an iMac 21.5". It is running Mac OSX 10.6.2 (Snow leopard). When I turn it on it passes the screen with the gear and the apple logo, but gets stuck on the blue screen, with only the cursor showing.
I have already tried:
1. Booting into safe mode and deleting all startup items.
2. Resetting PRAM and NVRAM
3. Running Disk Utility and repairing the disk.
Anyone have any suggestions on hwo to fix it?

Try this:
You will need to type some Unix commands. If you are not comfortable with this, I don't know of anything other than a re-install. But if you are careful, you should be OK. I recommend you print this out in a largish mono-spaced font so you don't miss any spaces (or add extra ones). Note that case is important.
Be careful. Some of these commands are dangerous, since you are going to be root.
Start up in Single-User mode by restarting the computer. After the chime press and hold down the COMMAND-S keys until you see white text on a black background. When this has finished you will see a prompt ending in '#', although there may be other messages. Enter the following commands after the prompt:
/sbin/fsck -fy
Press RETURN. Wait a few seconds for 8-10 lines of output. If the last line says repairs were carried out, repeat this command until you get a message 'The volume <yourdiskname> appears to be OK'. Then continue with:
/sbin/mount -uw /
cd /Library/Preferences
rm com.apple.loginwindow.plist
rm com.apple.windowserver.plist
cd /Library/Caches
rm -r *
cd /System/Library
cd /System/Library/Caches
rm -r *
reboot
Press RETURN after each command.
This should now take you to a proper login screen after the normal boot sequence. You should then Repair Permissions by using Disk Utility (in your /Applications/Utilities folder).

MacBook Air stuck in grey screen after ML installation

Hi everybody,
I have downloaded and installed Mountain Lion on my MacBook Air (2011). After the installation the computer restarted and stuck in the grey loading screen, showing the apple logo and the turning wheel. I've left it alone for hours but nothing happens. This is still the case and I cannot find a way out.
Here is what I have tried so far:
- Reload and reinstall ML via recovery mode (twice). Recovery mode shows me that 10.8 is installed, by the way
- Restart without peripherals connected
- Reset PRAM and NVRAM
- Disconnect all cables and let the computer rest
- Diagnose and repair hard drive (showed me a message that a Java-related group has a value of 80 but should be 0. Repair was "successful")
- Safe boot (A bar appears in loading screen but disappears after it is about halfway full and I'm back in grey screen)
Unfortunately none of this worked. I have a Time Machine backup but it is located at the other end of the country (long story) and I can't access it easily.
Do you guys have any more ideas what else I could try? I'd really appreciate it.
Thanks!

I'm having the same issue. My MacBook air is stuck on the grey screen with the apple logo. I've waited for hours. Has anyone found a resolution to this issue?

Stuck on grey screen after update

Hi,
I had my MacBook formatted about 2 weeks ago because of some software malfunction. I got the Snow Leopard installed and it was working perfectly fine until I had to update it.
I've updated the software from the Software Update pop-up and it would work fine but the latest update (October 9th) messed up my laptop.
It was an update for the SL software, two security updates, Java update and some other update I can't remember. All of them required a restart and I clicked to proceed.
The computer closes everything to go into restart and starts installing the software before it shuts down. Once it starts up, I get the start up chime but it stays stuck on the grey screen with the logo and the spinning wheel at the bottom. Its been stuck like this for a good 45 mins.
I shut it down by holding the power button and restarted it but it's stuck on the same screen as before.
What's wrong with it?

Start by trying this:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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 installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
If you are still unable to start then reinstall Snow Leopard. This will not erase your hard drive or disturb your data.

MBP stuck on Grey Screen after Mavericks Install

I have a MBP 5,5 and every time I try installing Mavericks my computer restarts and after the grey spinning wheel my screen flashes black and then stops at a grey screen. I have tried running in Verbose mode and I notice it said I have a SMC error and that it tries to use an old SMC. If I try installing mavericks to an external drive everything is fine. Could it be something configured in one of my programs?

PB G4 stuck on grey screen at startup

I've got a PB G4 running 10.5. Everything was going fine until a couple of weeks ago when startup started stalling at the grey screen, sometimes with the apple logo and spinny thing sometimes just blank grey. After reading up on this, I popped in the original discs and ran disk utility. It ran for a while (there were lots of red errors flying by, most of them said the same thing, something about reserved file does not have data...?), and at the end it said one volume was repaired and one volume could not be repaired. I tried the repair permissions button, but that wouldn't work.
Last night, I had to yank out the HDD so I could get files off of it for work. Assuming that my HDD is working (picking up an enclosure tonight; fingers crossed) and that I can cram everything back in and close up the PB, is there anything to be done? I understand that this laptop is quite mature, but was hoping to get some more time out of it.
Thanks!
Brian

When you get a volume cannot be repaired message from Disk Utility, you have a few options. If the error is a soft error, that is, where pointers or index are scrambled, a program like Disk Warrior or TechTool Pro can usually straighten things out. If those programs can't fix it, then it's usually a hardware problem. You could erase the hard drive writing zero's to it to see if that fixes it, although that may be temporary. If that doesn't work, buy a new hard drive, which may cost less than Disk Warrior and TechTool Pro. A program like SmartUtility can show you the SMART sensor indicators, which can sometimes help you with making a decision on buying a new drive.

MacBook Pro mid 2012 stuck on grey screen on startup

Hey guys.!
I need an advice from you guys.
I updated my Mbp few hours ago... It asked for a restart , I did after sometime but now while starting up I can't get passed through the grey screen with an apple logo and circle loading sign. Before this showed a loading bar also with it.
I can't figure out is there a problem with it or just takes time to finalise the updating or something .
Would love to get replies ASAP
Thanks,
A fellow MBP user

Did you try Repair Disk instead of Verify Disk? The latter does nothing.
It is possible the drive has failed. It's also possible the drive just needs to be reformatted which you would do were you to try my second suggestion:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Power Mac G5 stuck on grey screen after swapping machine

Greetings Friends,
I have changed my two HD out of one casing to another casing. Both HD worked fine, Both machines worked fine.
I have booted up the computer and now the computer sits on the Grey apple logo, with no loading wheel. After 2 mins, the fans kick into overdrive.
It does not boot.
I have tried alt + command + P + R, but it does not work
I have tried holding ALT down on start up of the machine, which directs me to a menu where I can select either one of my HD or the start up disc that is in the optical drive. I have tried selecting all of these with no success.
I then tried to swap all the internals back to the original machine to see if it still works, and now the same problem exists. Grey screen with APPLE logo, no boot.
Could any body give me any help or direction. I love these machines and would like to continue working with one of them as soon as possible.
They are a G5, 4 GB ram, OSX 10.5.8 & the other drive is 10.5.1.
Both have been working well until today.
Thanks.

Hello, first thing that comes to mind is a BAD HDD, does the other one boot with only the one original drive? Maybe I'm misunderstanding if it was added in the second slot or not!?

OSX Lion, stuck on grey screen at startup w/ spinning gear.

i believe i have tried everything i could find, so any info is good.
about a week ago my 2009 macbook pro 15 inch stopped starting up, always going to a grey screen with the apple logo and spinning gear.
what i have done so far.
reset nvram
repair disk and disk permissions.
try startup with various combinations of periferials
i am obviously able to start into lion recovery, but my time machine backups are on the other side of the world.
when i do a safe boot if stops with two entrys of nstat_lookup_entry failed: 2
any help is much appreciated

You can do two things
1: Install Lion over itself via the Recovery, won't touch your files or most programs.
Any program has a kernel extension file in System/Library/Extensions folder, that will get kicked out. Thus those few programs won't work and require a reinstall of their software
2: Install Lion on a blank powered external Disk Utility > Erase with Zero + GUID OS X Extended Journaled formatted hard drive, hold the option key and boot from it, same named user, and then access your internal drive to recovery files, disconnect then do #1
