Grey screen appearing intermittently
Hello,
since several weeks I'm experiencing problems with my screen: once I boot and everything is running it gets suddenly grey. The system continues working normally (I usually work with an external monitor as well and can continue without problems). The way to bring the screen back to life is to put the system in standby and coming back. At the beginning it wasn't a serious problem, since it happened once every 2-3 days, but now it's getting worse and doing it almost continuously. I think it should be a hardware problem, because I have a bootcamp windows system in the same machine and it happens there as well. It usually happens more when the computer isn't exactly horizontal and when I extend back to the end; although now it's almost constant.
I would appreciate any tips or comments before I send it to the apple store (it doesn't have a guarantee anymore...)
Thanks,
Alberto
Can you confirm if the problem has been coming to users re-attempting/relaunching the course again?
Can you check if the scenario is similar to what is explained in the article, if yes try the steps recommended to replace the DLL--

If not, then please share some more details if there any pattern in users/workflow that causes it.
Thanks,

your 13-inch Mid 2009 MacBook Pro requires 1066 MHz RAM, but you have 1333 MHz RAM installed. Try replacing the 1333 MHz RAM with 1066 MHz RAM — Macs can be picky about the RAM which they find acceptable. -
When I restart my Mac, the grey screen appears like usual. But it takes more than 40 minutes (or more) for it to load to finish restarting the Mac. What should I do to fix it?!
Disconnect all devices from your computer if you have not already done so. Restart again. If the problem has been resolved, you had a peripheral conflict. You will then have to reconnect the devices one at time, restart, to locate the culprit.
Login Items is another culprit. Check your login items.

My mackbook pro suddenly freezed and when I swiched off and on again, a grey screen appeared with an apple logo then a loading circle underneath, and after a few hours, a blue screen appeared. What shall I do with this?
What operating system version, and do you have any backups of your data off the machine? TimeMachine? Option Key bootable clones? Storage? DVD's?
A reinstall of the operating system may be in order as a last resort, so if any of these steps on these links get you into the machine, make sure to backup your personal data (Music, Pictures, Documents, Movies) off the machine to a non-encrypted powered external drive regular storage drive (not TimeMachine as it might be corrupted too) and disconnect as soon as possible.
Good Luck and report back all what you tried.
Also report what change occured before this tragedy happened, was there a Software Update? A EFI firmware update? Etc.

MacBook Pro won't boot. Grey Screen appears, apple logo then nothing
I'm very frustrated. I was using my laptop and suddenly the rainbow wheel appears and it freezes. I tried to hard reboot it and when it restarted a grey screen appears and the apple logo shows up. I bought it used from a Micro Center and I believe it's out of warranty. What is going on and what are my options?
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
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
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 4
Boot in safe mode. Note: If FileVault is enabled on some models, 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 corrupt 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 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
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.
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 Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
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. If you can't get to an Apple Store, go to another authorized service provider. -
Help me please just a grey screen with the apple logo appears and it looks like its going to start up but doesnt
See if you can boot into safe mode by holding down the shift key immediately after pressing the start button. Keep holding the shift key till a loading progress bar appears on the lower part of the screen. It will take a lot longer than normal to start this way. If you have Lion 10.7 installed you can try holding command-R keys to get intto recovery mode and run disk utility.

Imac reboots & grey screen appears with no further activity
I have a 2011 late edition iMac with 12 GB RAM, running os 10.6.8. I press the power button. The iMac chimes. Grey screen pops up and just sits there. No apple logo. Don't hear any hard drive activity from the iMac. Any suggestions? I have tried to boot up from the DVD drive, but nothing happens. Thanks in Advance!!
Hi Dr.Yoda69,
Thanks for visiting Apple Support Communities.
If your Mac only starts up to a gray screen, I recommend trying these steps next:
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Perform a Safe Boot
Simply performing a Safe Boot may resolve this issue.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
If your Mac starts up as expected, immediately try restarting.
If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
Reset the NVRAM / PRAM
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Reset the NVRAM / PRAM.
If the gray screen issue persists, go to the next section.

Mac won't start grey screen appearing
My power mac g5 that is running leopard wont boot up.
Everytime I try to start it, shows a grey screen telling me to restart the computer (appearing in english, french, spanish, and chineese i think). I accidentaly deleted a folder on the root menu of the HDD entitled "usr". How can i fix this.I tried this but it didn't work. I think it is my keyboard because even when I turn the computer on the green led on the caps lock button doesn't light up. I even tried a regular USB keyboard and I had the same result.
I guess I will have to find my leopard CD.
Is it possible to just restore system settings from the leopard cd so that I don't lose all my data? -
Can't open PDF on iPhone - blank grey screen appears
Hi. I have downloaded the latest reader on my new iPhone 6. I cannot view PDF douments. If I try to open a file, Safari opens to a blank grey screen. I can see the "open in" prompt but cannot click on it. Any suggestions?
Thanks.Yes, that is a well-known problem: http://support.microsoft.com/kb/2716529
The Fixit on that article only works on Windows 8, but I can give you a script that makes the registry modification on Windows 7. Download, unzip, then run the attached registry script. -
Grey screen appears during normal use
I have never seen this before and the other discussions seemed to be more about restart.
Normal startup, normal login and possible to use the iMac normally for a random but short period then all of the sudden grey screen. Blank grey screen.
Reset PRAM and smc, Verified Disk (OK), checked and fixed one permission and there is a lot of free space.
Does anyone have any other ideas that I could check.
Much appreciatedHello,
Open console in Applications>Utilities, check the system log for the date/time of the last problem & the Startup right after that for clues.
Have you blown the dust out lately?
Get Temperature Monitor to see if it's heat related...
http://www.macupdate.com/info.php/id/12381/temperature-monitor
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Macbook won't start up, white/grey screen appears folder and question mark.
My macbook was freezing up, so i pressed the power button to shut it down and it won't restart. It just goes to the blank white/grey screen and a picture of a folder with a question mark on it shows up. What should I do?
I am going to try and explain this.
When you purchase a Mac, that machine comes with a license to run the current Mac OS at the time of purchase. The license resides with the computer, not with the installation media. Therefore, if I purchased 3 iMacs, at the exact same time, and they were the same model, I could use the install media from one on any of the other machines (and don't tell me it won't work, because I have done it before). This does not violate the EULA. Do you really think that a company that purchases hundreds or even thousands of computers would keep the install media for each one? The media is not tied to the computer; it's the license for OS X that is bound to the computer. Consider when you purchase a family pack of Mac OS X, you don't get 5 discs, you get 5 licenses, and one disc.
What the EULA is stating, is that you cannot have one license running or installed on two computers. It does not say that you cannot use the same install media on different computers (assuming you have the proper number of licenses). You are also wrong in saying that you can uninstall Mac OS X from one Mac, and then use its restore discs on another computer legally. That is only legal for "Retail" copies of OS X. I believe the restore discs are the equivalent to an OEM (Original Equipment Manufacturer in the PC world of computing) version of OS X. I am almost positive they are non transferable. -
What do I do when only the grey screen appears on my Mac desktop?
When turning on computer it will only get to grey screen after the chime.

How to install OS X on a new or faulty HD without Internet recovery
Corrupt and new disks might not have a working Recovery partition, but there are still ways to access one and reinstall OS X, if needed.

Macbook pro acting as if it was on but only grey screen appears.
Hi All,
I am having some rather strange issue with my MBP which is driving me mad.
A couple of days ago I was watching a video and all the sudden the screen started sort of vibrating and then the whole system just froze, had to shut it down by holding the power button.
I then switched it back on, it started booting up but it got stuck at the grey screen with the apple logo and that little wheel spinning, which then stopped spinning and it just stayed like that. Initially I thought it was just the grey screen issue people sometimes get, but I actually noticed that the system is on, or at least is behaving as if it was on (I can change the volume, the buttons are also active, but screen is still the same grey with the logo and wheel).
What I have tried so far:
Safe mode- did not help
Verbose mode with command fsck -fy - found no issue
Booting up from installation disc - it asks me to shut down the computer
Resetting the NVRAM - did not help
Single user mode - did not help
Has anyone got any idea what the problem might be?
Thanks,
RobHi there,
Thanks for your reply.
It says "You need to restart your computer. Hold down the power button until it turns off..."
Below this is the same message in other languages such as French, German etc...a black box in the middle of the screen with I/O sign in the background.
Thanks,

I try and start my imac and a grey screen appears with the apple logo and shuts down what is wrong?
my i mac just shuts down after apple logo appears what is wrong?
Your post only says iMac. We need to know what version of OSX you are running.
Did your computer come with Installation disks? If so, place the DVD in the DVD drive and reboot the computer while holding down "C" until the comuter boots.
Run Disk Utility on your hard drive and post back any messages you receive.
