I don't think it's exactly an incomplete installation brody, but most likely in-correct permissions somewhere along the line that either happened, or became magnified during the upgrade. Also, it could be corruption as well.
First thing to do, is boot up holding down Shift key to do a safe-boot so we an clean up any corrupted OS caches, after that do another reboot, but go to the Lion recovery, and scan the HD for errors, repair any if you find them, and then try to do a Repair Permissions job.
That should fix the issue, if not, we can start doing a PRAM reset and SMC for good measure.

ActiveX Viewer on IE displaying grey screen

We are running crystal enterprise XI rel2 with FP4.7. When running reports via infoview or the crystal management console, reports display. but when running the reports via a java app through the webcompadapter, the reports only return a grey screen. Reports are failing 100% in dev, 50% in test and never in Prod. I have thoroughly reviewed entrprise setup on our Windows 2003 server, and our AIX Weblogic env for the webcompadapter. the environments are the same across dev, test and prod.
Has anyone come across this before that can lend a hand?
thanks in advance

How to choose which monitor displays "full screen preview"

I have a dual monitor setup and have Bridge configurated so that on the left monitor I have the panes "maps", "filter", "keywords" and "content" and on the right monitor (which is a better and callibrated monitor) I have the pane "preview".
Now if I select one or more tumbnails in the "content" pane on the left monitor, they show up in the "preview" pane on the right monitor.
Until recent, when I selected a single tumbnail in the "content" pane (left monitor) it showed up in the "preview" pane (right monitor) and upon hitting the space bar it was shown full screen on the same right monitor and upon left-click on the full screen immage, I got a 100% preview, again still on the right monitor.
Now the problem is that suddenly, upon hitting the space bar, the full screen preview is no longer shown on the right monitor but is shown on the left monitor. (Same problem for the 100% preview).
I hope I made clear of myself and that anyone knows how I can change this back again?

The window was indeed expanded to both monitors and the monitors were aranged correctly but upon your sugestion I temporarely switched everything back to default "one monitor setup" and then back to "two monitor with extended window". I also did a reset of my workspace as sugested.
The result is that everything is back and working as it shood. Problem is solved.
Thank you very much.

2006 Mac Pro + NEC 3090 - grey screen not displayed during boot

I have a September '06 Mac Pro 1,1 (Woodcrest variant) hooked up to an NEC 3090 30" LCD monitor, running OS X 10.5.7. Previously, I was using an Eizo S2110W 21" LCD; turning the monitor and computer on would cause the following to be displayed (in order):
1. Light grey background with dark grey Apple logo with spinning thing.
2. Solid blue background.
3. Leopard wallpaper.
4. Log-in dialogue.
Since using the NEC, the grey screen is not displayed at all: the display stays blank until the blue screen is displayed, and then the Leopard wallpaper and so on. This is using the 2560x1600 native resolution of the display, and has occurred using both 10.5.6 and 10.5.7.
If I change the resolution to 1280x960 and boot, the grey screen is displayed. If I change it to 1600x1200, I get weird corruption on-screen during the period when the grey screen should be displayed; for some reason, this includes part of the desktop wallpaper I was using before I rebooted.
Resetting the non-volatile RAM using Command-Option-P-R works for the very first time I boot the computer, though the grey screen is displayed at very low resolution. If I reboot from the log-in dialogue immediately afterwards, normal behaviour occurs - i.e. the blank screen.
The upshot of all of the above is that if I want to boot into Windows, or install OS X (e.g. when Snow Leopard comes out), I have to remember to boot into my existing OS X installation, change resolution, reboot whilst remembering also to hold down the ALT/Option key. It would be much easier if I could do away with having to change resolution.
I have tried connecting the monitor to a PPC Mac mini at 1600x1200 (it won't go any higher), using Tiger 10.4.11 (not sure of exact version - the latest). At this resolution, the grey screen is displayed.
Using a '08 MacBook Air (first generation) and the supplied DVI adapter, also at 1600x1200, nothing is displayed on the NEC until I get to the log-in screen. This occurs if the NEC is set to be the primary display or the secondary one - the only difference is where the log-in dialogue is displayed. I am not familiar with dual-screen behaviour, so I can't say whether anything is supposed to be displayed or not (i.e. does the grey appear on both displays?).
I have been in touch with NEC Europe support on this issue, who suggested it might have something to do with the 10.5.7 release. I know this not to be the case, as it was occurring prior to 10.5.7 being released.
Any ideas?

Put more of your hardware listed in your profile.
I looked and don't see you list your graphics card anywhere.
Graphic card it came with was either X1900 (watch for heat and dust bunnies and clogged vent);
OEM 7300GT (seems unlikely).
You could have replaced either with 8800GT or ATI 3870.
Require 10.5.2+ ideally 10.5.6+.
Some problems cropped up with 10.5.7. 10.5.7 doesn't work on some (many) 3rd party displays and stay with 10.5.6 if necessary until it is fixed or resolved.
But you say it happens with 10.5.6 also, and was doing so before 10.5.7? which makes your problem somewhat different or unique.
Zapping PRAM or NVRAM reset obviously shouldn't be needed repeatedly. And your graphics card probably needs to be replaced, or test with another card to rule it out.

Hi, I downloaded Yosemite this evening. I downloaded o.k., it installed o.k. and then it restarted the Macbook and now it seems frozen. There is nothing but a grey screen, the apple logo and a bar that is half black

Hi, I downloaded Yosemite this evening. It downloaded fine, it installed fine and then it restarted the Macbook. Now it seems to be frozen. I have nothing but a grey screen with the apple logo and a bar that is half black and half grey. It's been like this for over an hour. Should I worry or is it still working at something? How do I fix this if it's not still working at installing something. Thank goodness for this poor old pc as backup.

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.

My MacBook Pro won't start - it just displays a grey screen with flashing icon of a folder with a question mark in the middle. Help.

It started while I was using Adobe InDesign, and that program froze, then crashed. When I tried to reopen the program, the error message I received was simply "Error: 16".
I tried to take a screen shot of the error message for reference, and it gave me a message saying I couldn't because I didn't have access to the files where it would normally store the shot.
Attached to my computer at the time was my Seagate Free Agent Go-Flex for Mac backup drive.
So, I closed any open applications, and restarted my computer. But it wouldn't restart. It only displays a grey screen with a flashing icon in the middle of a folder with a question mark on it.
I have no idea what happened - I wasn't using the machine any differently than usual, and it only had a few basic applicaitons open in addition to InDesign (like Preview, Text Edit, Microsoft Word, iCal).
I have MacKeeper on my MacBook, and I keep it clean.
Does anyone out there know what this flashing icon indicates, and if there is anything I can try on my own to fix it?
Thanks.

May or may not be a contributing factor, may have kicked in at a wrong time or running root code.

Well that explains it, MacKeeper is almost malware.
http://applehelpwriter.com/2011/09/21/how-to-uninstall-mackeeper-malware/
Search the forums here for "MacKeeper" they will tell the whole story, crapware.
Disconnect all drives, follow the "Grey Screen" instructions and hold Shift key down while booting, if you get into OS X , immediatly backup your files to another drive and disconnect.
In my opinion you should first check to make sure you have a backup of your data, then just erase the entire internal drive (hold c boot off the 10.6 disk, use Disk Utility), reinstall OS X, same user name, update to 10.6.8, c boot off the 10.6 and Repair Disk (to fix a update error) install your programs and finally return files from backup into the same main user folders like before (Music, Docs, Pictures etc.)
A pain it is, but you've hosed your system and in the process you might as well rebuild everything and have a fast machine again. So happens to clear MacKrapper, uninstall CS5 and any other junk in your system at the same time. Fresh, clean, lean and mean.
Learn to Carbon Copy Cloner to a external drive that new pristine boot drive, you can hold the option key and boot from it (even update it), which is a real bacon saver when something like this happens. Also it's free to use, donations accepted.

Mac OS X: Gray screen appears during startup - Apple Support

Mac OS X Lion displays grey (No background) login screen before Apple boot screen

Macbook Pro 13" (2011) Upon startup, displays a grey screen, then after a few seconds, the logon screen, I would logon, then it would show the Apple White boot screen, then it would ask me to log on again (sometimes)
Anyone else have this problem? any solotion would be greatly appreciated...

Try reinstalling Lion:
Reinstalling Lion Without the Installer
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. Alterhatively, 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

Grey screen display even though "aqua" theme selected

Hi, I was wondering if anyone could help me as this is really annoying me! Recently, instead of my theme being blue, it is grey. My computer starts up with a grey screen and apple logo (instead of blue like before), and even though I have selected "aqua" it is still grey or graphite. I haven't changed any settings. When I go to system preferences and display, if I select the default profile, the colour LCD one, it is a weird brown/yellowy color. All the other ones are various shades of grey rather than blue (which I have selected because it is preferable to the brown). I have no idea why my computer is doing this as it seemed to be working fine before. Any ideas/help would be greatly appreciated!

Hi, thanks for the reply but no that is not it. The background has colour, it is just the setting... like the dock is grey when I swear it used to be bluish, as well as bootup, and toolbars etc... and when I click the default Colour LCD setting it goes a weird brown colour. It is not a huge deal, just weird!

Hello Tony from New Zealand (great place, I visited once):
Welcome to Apple discussions.
Take a look at this article to see if it helps you fix the problem:
http://support.apple.com/kb/TS2570
If it does not, I think I would reinstall OS X 10.6 (upgrade from your software install DVD) over your existing system. Then I would run software update to bring everything to current levels.
A good backup before any software change is always a very good idea (I use both Time Machine and SuperDuper).

My ibook G4 display greys out after a few seconds, clicking on the screen returns it to normal.

My ibook G4 display greys out after a few seconds, clicking on the screen returns it to normal functioning. I have adjusted the delay times before the computer goes to sleep to no avail, so I'm thinking this issue stems from something else.

Have you tried resetting the PMU? The PMU (Power Management Unit) has control over the sleep function, so resetting it may help if the iBook is sleeping unexpectedly.

My G4 Apple PowerBook will not boot further than pale blue/grey screen displaying "flashing file symbol / flashing ?"

My G4 Apple PowerBook will not boot further than pale blue/grey screen displaying "flashing file symbol / flashing ?"
Last previous action: Used Firewire cable and "Target Mode" to copy files from G4 eMac to the PowerBook.
I worked from the eMac to the PowerBook, making the PowerBook the "Target". Files seemed to transfer OK. Won't boot from InstallDisc. Holding down T on startup results in Target mode screen. I have a G4 iMac and a G4 eMac. Can I use either of these with Firewire cable to boot-up my PowerBook ?
I'm new to using this Communities & Forums Help. Can someone please help me to get going again ! ! Thanks for your time. Graflood

Hello,
It sounds to me like the PowerBook is stuck in target disk mode.
It's expecting the iMac/eMac to be there when booting. Seeming it's not attached, it will show a flashing folder.
If your PowerBook internal drive is bootable, then simply hold down the option key when booting and select it's internal hard drive. That should boot your PowerBook into Mac OS X.

Why won't my Intel iMac boot up, either from the internal hard drive or the DVD drive? It just displays a light grey screen, without any other icons, etc. The fact that it won't boot from the original system DVD is what baffles me the most. Any ideas?

It uses the latest version of Mavericks. Thanks!

If the C key for Install Disc or R Command for OS X Recovery startup commands are not working, try holding the Option key for the Startup Manager.
see > Startup Manager: How to select a startup volume
If that does not work and you using a wireless keyboard, it may have become unpaired and you need to dig up a USB keyboard to invoke the startup commands.
