After update Mac Pro boots to grey screen with Kernel Panic. Help please.

It would be great if someone can help me out. Yesterday I did a software update of iTunes and osx (it said to ease update to Lion) and now my Mac Pro tower (MacPro3,1) boots to a grey screen, kernel panic, telling me that I need to power down and restart my machine. I can boot into osx via the safe mode but unfortunately I don't have an install disk to repair the system disk. What are my options?
The machine appears to work in safe mode. I have tried resetting the PRAM. Any help is greatly appreciated. Thanks.
In safe mode, I get this error report.

There's no point in reinstalling the same driver. It hasn't changed. It's incompatible with the OS update. Contact the device manufacturer to see if there's a driver update. In the meantime, you should physically remove the device so the driver doesn't load. If you uninstall the driver and leave the device installed, that might also cause a panic.

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.

Macbook Pro won't boot past grey screen with Apple logo and then shuts off

This is a long story...
This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I messed around a little bit in system preferences thinking I could fix it on my own, not really knowing what I was doing (I'm a *******). I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart.
Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. Please help. I already tried the Command-Option-P-R keys trick like five times.

If you have a full retail DVD for 10.6 you can boot from that by holding the C key during startup...but you will then be in install mode if that is what you want to do. At least go ahead and see if it will boot ok from the 10.6 disk and then you can decide what you want to do further.
Apple does not have 10.5 for sale anymore from what some other users have said on here so if you want to go that route you will have to find a copy for sale such as from eBay or one of the Mac resellers.
Before taking the machine to someone, try booting from 10.6 and see if that works...that way you can narrow down problems the machine may be having.

Mac Mini boots to grey screen w/ symbols

This morning my Mac Mini will not boot to Mac OS - it displays a light grey screen with a thunderbolt and some weird symbol that looks like a wheel/hub with 3 arms - 1 arm is solid and the other 2 are made up of lines perpendicular to the hub.
The Mac Mini was recently upgraded to Mountain Lion - running lastest updates - this was a few days ago. The display to VGA through the mini display port. Using magic mouse and usb keyboard, that's about it.
Any idea what has happened? Or what isn't happening?
Thanks for your help!

OK - It looks like I'm stuck in target Disk Mode .... I suspect my kid had something to do with this or a stuck key.
Can someone recommend the best wat to get back to normal boot?

Macbook Pro boots to grey screen but won't start up. How do I fix it?

Today I set my Macbook Pro on the couch but it slipped of and landed on its side (closed) on wood floor. Nothing broke, it all seems pretty normal. I pushed the power button to turn it on, but it only loaded to the grey screen with the apple and the spinning circle. I left it sitting there loading for several minutes, but nothing happened. I tried force shut down several times and restarted it. It still did the exact same thing. How do I fix it?

My Computer Won't Turn On

Boot Camp: Early 2011 MacBook Pro boots to black screen with blinking cursor after windows 7 installation.

I bought and downloaded the windows 7 ultimate edition 64 bit iso, then proceeded to perform a correct burn to a DVD one at the slowest speed and one at the fastest. all went well. so I open Boot Camp assistant and follow the instructions to the letter, downloaded the driver support to the flash drive. partitioned my drive with more than enough room 150 gb. its starts its install. I get through everything seamlessly where I put in my info all with the exception of my activation code. yet it still continues to finalize the install and does another restart. boots back up to either A. black screen saying press any key to boot to my install disk. B. if I take it out just a white curser. also I read it may be because I had the flash drive in while I was trying to boot so I removed it as well, same result. any input would be much appreciated.

G4 mirror can't won't boot past grey screen with dark gray apple

Before this the computer was operating fine.
I just went and downloaded the latest versions of itunes and Safari. It stated that I had a corrupt download of itunes. It went thru the normal downloading/install procedure. When it went to restart from the install, it just hangs up at the light grey screen with the dark gray apple and I get the spinning wheel. It stays here for one/two minutes, then shuts itself down. Any ideas for fixing? Also I do not have any install disks. Thanks.

*Option 1*: Boot from your bootable backup drive, then erase the internal drive and clone the backup to the internal drive. You can use Disk Utility in the Utilities folder on the backup drive. Don't have a backup? Good time to start planning a backup strategy. Move on to:
*Option 2: Download AppleJack* - VersionTracker or MacUpdate - and read the documentation carefully. Then install the utility and use it to perform repairs and maintenance on your normal startup drive. Note that to use AppleJack you must be able to startup in single-user mode. If the existing system is unable to start properly into single-user mode, then you cannot use AppleJack.
*Option 3:* Purchase a copy of Leopard from an Apple Store or Apple retailer. Use it to reinstall OS X by doing an Archive and Install:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
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.) 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, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Update failed... Now I have grey screen with flashing icons. Please help!

I was installing an update for Leopard and I wasn't connected to a power source. I thought it would be ok because I had a full battery. The screen was half closed over also so it may have switched off during update. Whatever happened, now my MacBook Pro won't boot up. I get a grey screen with a series of flashing icons one at a time (apple logo, circle with line through it and a folder with a question mark).
The other problem is that my system disks are in my friend's house a thousand miles away so I can't boot up from my system disks. Can anyone offer any advice please? I'm desperate!

If you can start up in target disk mode, connect your computer that works to the one that doesn't. (I'm assuming you have another computer since you can't get to the Apple Discussion Forums with a computer that won't start up!)
Use the computer that doesn't work as an external drive to the one that does.
Go to this part of the Apple Downloads website and find the update you were installing. Download it as a standalone installer, and try to install onto the external HD. If it works, problem solved!
If it doesn't work, you'll need to follow Alexandre's advice and go to the Apple Store to get working installation discs. However, you can have access to your important files whenever you want them by simply using Target Disk Mode.

Macbook won't boot past grey screen with Apple logo and spinning wheel.

For some reason, after about 1 year and 10 months of owning my Macbook, it decided this morning not to load past the grey screen with the Apple logo and spinning cog/wheel.
I used it for a couple of hours beforehand, and it was working fine. Software Update prompted me of about about 4 or 5 updates; I can't remember exactly what was downloaded, but I think there was a Security Update and iTunes among them. I restarted, left it to install with no errors, but when I logged in, Safari and iTunes were running incredibly slowly. I also noticed that the volume keys weren't responding, as well as the power key to bring up the "Sleep, Restart, Shutdown, etc" dialog box. I forced shutdown, hoping a restart would solve my problem, and that's when my troubles started. I originally just left it, but after about an hour the wretched thing was still spinning.
So far, I have done a number of troubleshooting tips on a variety of websites. I have tried taking the battery out and holding down power for 5 seconds, resetting the PRAM with option, cmd, p & r, and holding down power until the sleep light flashes rapidly and the computer lets out a large "BOOOP".
I have booted off my Leopard install disk with both option and c, repaired the hard drive a number of times, with there being no errors whatsoever. I have tried repairing permissions, but everything seems to freeze up, except the mouse.
For some reason my computer will not boot into safe mode, either, and holding cmd & s at startup doesn't get me to the stage where I can enter commands with the keyboard.
Unfortunately, because of my puny 60GB hard drive, I only have 1GB of free space left and cannot reinstall Leopard without wiping my hard drive.
I would greatly appreciate it if anyone could assist me with this unfortunate dilemma. It's such a shame that my computer has been fantastic for so long and now decides to play up. (Maybe it's just Apple trying to get me to buy a new 2.4Ghz aluminium Macbook sooner than I was planning...)
Thanks very much.

Hi ds,
Sorry to hear you're having such trouble!
Unfortunately, the best thing you can do at this point is reinstall Leopard (and then attempt to install the combo updater, too). If you don't have a backup of your machine, you could boot it into Target Disk Mode (by holding down T at startup) and then attach it via FireWire to another computer to salvage your files.
I recently had to repair a machine with this exact same problem, and after messing around with that for several hours, I'd have to say that I think that an Erase and Install is the way to go. If you then migrate over your user data and start having troubles, you at least know where the problem lies. I suspect, though, that having a clean machine with all of the new updates applied will be the end of the issue.
Sorry to be the bearer of bad news. There are a few other things you could try first; you could, for example, manually download the relevant combo updater from Apple's website and attempt to install it to your damaged machine while it's in Target Disk Mode. If you have a copy of Disk Warrior, that too is certainly worth a shot (and in some cases may be the saving grace). In my experience, though, a failure of this magnitude isn't easy to resolve.
Hope that helps.

MacBook Pro has a grey screen with circle and slash and will not start up or start into safe mode.

MacBook Pro has started to get a grey screen with circle and slash and will not start up or start into safe mode. This happened once previously, however, it allowed a safe mode reboot and then worked for a week or so. While utilzing the machine, it started with the spinning beach ball for about 5 minutes, went into a shut down mode and then rebooted and came back up with the grey screen with a circle and slash after a few minutes. For the past three days it has been stuck and will not allow it to boot into safe mode. Any idea or suggestions?

Try starting the MBP with the OPTION key down. If you see two HDD icons, select the recovery Icon. From the 4 option menu, select Disk Utility. Select Disk Utility>First Aid and run Verify and Repair.
If you cannot get into the recovery partition, make an appointment at an Apple store genius bar.
Ciao.

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.

Macbook Pro stuck on grey screen with Apple logo

Macbook Pro was purchased in mid-late 2009 and is running on OS X 10.6. Today is suddenly stopped responding and so I turned it off. When I turned it back on it opend to the grey screen with the Apple logo and the loading icon and that is where it stayed. I have been searching for the answer on different forums but have yet to find a solution. My hard drive is appearing in the Disk Utility but not in the box when I try to reinstall OS X. Any suggestions on what to do?

Create a data recovery, undelete boot drive

Will that erase all of the files on my hard drive? Or will it just erase and reinstall the operating system? I do not have my files backed up.

Macbook Pro boot shows black screen with white text cursor

Hello,
I have a MacBook Pro 7,1 MC374xx/A running Mavericks. My box has two internal hard drives in it. One had the Mac OS installed to it, and the other has absolutely nothing on it. I decided to give Boot Camp Assistant a try and chose the hard drive with nothing on it to install Windows on. I also had an external USB DVD drive attached with the Windows 7 installation disc on it.
So, next thing ya know, my Mac reboots and loads a black screen that says "Memory Overload." I take out the external USB drive and restart. Then it said, "No boot devices found." Now for whatever reason, it's just a black screen with a white text cursor.
What the heck happened?
I selected command R and confirmed that I installed Boot Camp on the right hard drive (the drive that did not contain my Mac OS). Then, I completely erased everything from the drive with Boot Camp on it. But still..black screen with white text cursor.
I have no Time Machine backups available so I'm forced to reinstall the OS. Any idea why this happened? It seems I must have attempted to install Boot Camp improperly. Any ideas or instructions on what to do now or how to install Boot Camp successfully on the Macbook Pro I own?
Earnestly,
Speck

Booting problem (grey screen with spinning wheel) PLEASE HELP!!

I have and ibook G4, i shut it down the other day and whent to school, when i got home, i tried booting it up, but its just goes to the grey screen with the apple logo and the spinning wheel, and doesnt go any further. i can hear the computer thinking, it that helps at all, but the weel just keeps spinning and it never gets to the login screen. Whats the problem? What can i do to fix it? somebody please help!!!

Hi,
Try starting in Safe Mode by holding the shift key as you start. Release it when you see the logo and spinning progress indicator. If successful restart normally.
If that doesn't work please post the version of OS X you are using (Panther,Tiger,Leopard) for more trouble shooting suggestions.

Grey Screen with Apple Logo - HELP

First of all: I know there is another topic for this, but this is a different problem (i think?)
I was installing snow leopard... it came up with that green tick with restart below it. It shut down and when it booted up it went to the grey screen with apple logo and it hung there for 6 hours until I turned it off. The disc is still stuck in there (tried holding in the mouse button) and it won't come out. I also held in the C button which made the disc drive make a lot of noise.
Any help would be appreciated.

Here there is a lot of topic about that subject.
By any change, have you completed all upgrade that your mac asked you before installing 10.6?
If yes, you're in this situation: http://support.apple.com/kb/TS2990 , you can try to install it again. Some people said that it took them 3 times to make it works.

After update Mac Pro boots to grey screen with Kernel Panic. Help please.
