Mackbook pro stucks on a gray window while booting

I have a macbook pro 15", that was working without problems, and when i turned on yesterday, the computer stucks on a white-gray screen, and doesn't make anything else. What could be damaged? May I be able to recover disk info? Thanks.

Use Safe Mode, reboot holding shift key down, as soon as your in, copy your user file folder to a external drive and disconnect before doing anything else.
If you can't command r boot into the recovery partition...see if you can c boot off the 10.6. installer disk and using Disk Utility to repair the drive.
If you don't see the drive, it's likely dead.

I have a mac pro wich will not open windows in boot camp i get to the two options select windows but iyt will not load can you help please

i have a mack pro which will not open in windows from boot camp get to the two options and select windows drive but it will not open can you help Please

Hi there, Well, i thing i might have had the same problem (if you dont mean the selecting part, then try keyboad with usb and without if u dont have a macbook pro or so), i did the same and after selecting windows it said "No bootable disk" or " no boot disk" or something like that and the installer wont start when i was trying to install via CD/DVD.
The sulution is to use 2 usb-drives, one for the support drivers from apple and one for the windows it self after burning the CD/DVD to the usb on a PC using the windows own tools and creating a ISO file.
(there might be problems whit CD/DVD install sometimes)
The ISO file on a own USB is the most importat thing!! (and even apple and windows didnt know that but me and a technikal support guy from the store i bought it managed to fix it after like 4 days )
Hope it work now mate!

Reinstall Lion, Mountain Lion, or Mavericks without erasing 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.
Repair
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Why is my macbook pro stuck on the gray screen?

I turned on my macbook today and tried to turn it on, only to find out that it decided to stay on the gray screen for quite a while. I have tried to re-boot the system quite a few times, but nothing has helped. I then googled my situation to find a solution. I came across a post from someone who recommended holding down command + V and the power button. A black screen then appeared with a bunch of white writing. I haven't touched it because i dont want to mess it up any more that i already have. PLEASEEE HELP ME!!! Thank you!!!!

Just take it to the apple store. Same thing happened to me and they fixed it by going on the black screen but dont mess up with that screen let them fix it.

2010 mackbook pro stuck on start up screen

I bought a used 2010 Macbook Pro and it worked just fine. I tried to do a factory restore with the disk that the old owner provided to me. I did the reset and noticed that she gave me a 2011 disk. It would never get pass the apple startup screen after that. I tried to do a factory restore (command s)thinking that it would bring it back to before I did the restore with the 2011 disk and now it is still stuck on start up apple screen but I can hear the tutorial on how to set up your macbook pro. I will get the 2010 disk but for right now would like to be able to use the laptop. Help

Command s boot enters Single User mode, so all you need to do is hold the power button down and reboot again (without command s) and you should see the welcome video for setup.
2010 MacBook Pro's need the machine specific dark disks (not white) from Apple.
Also try a factory restore again, (hold c or option/alt to boot) this time use Disk Uitltiy (under the Utilites menu) to erase the ENTIRE drive, then quit and install OS X 10.6

MacBook Pro - Sudden performance drop in Windows via boot camp

Hi all!
I am the owner of MBP 2.4 - 8600m gt - 4gb I was using it for around one year with no problem but and from some time I have noticed a big drop of the performance...
On the boot camp I have COD4 which was running smoothly with 80-125fps but now it is barely 30fps with the same configuration... same story with games like TF2 and L4D..
What I have tried after this drop:
* format C: and getting fresh system
* different graphic drivers
* playing with directx settings
* checking the power management
* reset PRAM, SMC
* Apple Hardware Test
* playing without battery
* tuning fun speed
nothing helped...!
I was reading that those MBP have problems with bugged GeForce
( * Distorted or scrambled video on the computer screen
* No video on the computer screen (or external display) even though the computer is on) but mine MBP is not having any of those...
I was also looking online for similar problems and I have found those topic touching same issue with the same model of MBP...:
http://discussions.apple.com/thread.jspa?threadID=1583573&tstart=75
http://discussions.apple.com/thread.jspa?threadID=1792525
some other topics as well but I cannot find them right now.. the problem is that nobody knows why this strange thing occurs...
Please help me?

For starters, using a different graphics driver and playing with DirectX settings may make things worse. In general... for any notebook, you should be using the driver from the manufacturer. Unlike desktop graphics cards, notebook GPUs are generally configured specifically for the machine they are used in.
Playing without the battery will result in SIGNIFICANTLY poorer performance. The system will drop your CPU speed nearly in half when running without the battery. This is by design.
Doing a clean install is the one thing that you did that I would think would resolve the problem if it were related to Windows. After you did the clean install, did you just use the Apple provided drivers?
As you mentioned, the problems with some of the nVidia GPUs have generally not resulted in performance issues... but rather stability issues which you do not seem to be having.
Do you have antivirus software installed? I'm not suggesting a virus, but rather many antivirus programs are set to perform scans automatically in the background which can have a significant impact on performance while the scan is running. Other things such as defragging, etc. can cause performance hits.
You can launch the Task Manager... click on the "Processes" tab... then click on the "CPU" heading. This will sort your active processes with the highest on top. If you click on the CPU heading and the first few are "0"... click on the heading again (it is probably showing in ascending order instead of descending order). What are the first few items taking up the greatest percentage of your CPU? They may fluctuate a little... but the biggest culprits should stay among the top few.

MacBook Pro Stuck In Sleep Mode - Won't Boot

LAPTOP
2008 17" aluminum Macbook Pro running Snow Leopard
SCENARIO
I was using my laptop, closed the lid and took it to the office. Removed it from the laptop bag and it would not come out of sleep mode using mouse / keys. I hit the power button once (this has happened before and hitting the power button once has woken it from sleep mode). This did not help. I held down the power button for a hard reboot. The laptop shut off. Now I can't get it to turn back on.
ISSUE
When I hit the power button to turn it on:
The SIL blinks twice slowly like it's in Computer Sleep state and then the laptop turns off.
When I hold the power button to turn it on:
The SIL blinks slowly once like it's in sleep mode, then stays solid and dim for 4 seconds, then blinks very fast for 2 seconds, then goes dark for a second, then blinks slowly once more like it's in sleep mode, then the laptop turns off.
In both instances, I can hear the dvd drive begin to spin immediately after hitting the power button. Also, when I put my ear to the laptop, I can hear the hard drive start up before the laptop shuts off.
TROUBLESHOOTING
I've tried the following. All resulted in no change.
- Reset PRAM / NVRAM
- Reset SMC
- Checked RAM was installed correctly, wasn't jiggled loose for some reason
- Boot laptop with power cable, no battery
- Boot laptop with battery, no power cable
- Boot laptop with power cable and battery
- The above 3 boot scenarios with PRAM / NVRAM reset and SMC reset

I just purchased my second fresh battery for this machine and cannot afford an entirely new laptop right now. Any help is greatly appreciated. Thank you so much in advance.

Did you figured something out ? Mine, of similar age, started behaving the same yesterday. Since I replaced most of the original devices, I suspect the onboard clock battery being depleted by now... ? I'm not even sure there such a battery in there.

Forzen gray screen at boot

I'm using an iMac that was new in Dec '12. 27-inch I think it's still the current model.
Lately I've been getting long if not terminal hang-ups at boot on the plain gray screen.
The only system maintenance I have with this Mac is to confirm and correct my preferences on the main drive, through Disk Utility. I know there is much more to clean up in the system.
What program should I be using to do this with?
I used to use Onyx, but that is now only a pay program now. If I must use a pay program I want to get the best value for the program.
So my question is two questions.....
1. Are there free programs that will clean up the caches and whatever else needs attending to?
2. What is the best pay program for maintaing a Mac?
Thanks

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. Note: If FileVault is enabled, 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 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.

I need sound & wireless drivers for mackBook Pro after insalling windows 7

Hi
I just bought a Macbook pro 2.56 and installed windows 7. I haven't been able to install driver for Audio, Ethernet controller ( wireless as well) I searched on the web and followed a a few suggestions which was trying to install it from DVD OSX install came with the MBP and as well as installing the driver from HP that some people tried and fixed the problem . I am running Parallel Desktop 4.0 and it seems I can't get to install these driver that shows are missing in device manager. Please advise .
Thanks

Hi matchmate,
by installing the Parallels Tools while running Windows inside Parallels usually installs all needed drivers, including sound, ethernet etc.
Parallels currently does not list 64-bit Windows 7 in their list of supported guest OS (operating systems), so it seems that you are, for the moment, out of luck.
http://www.parallels.com/products/desktop/sr/
Future updates/upgrades of Parallels might include 64-bit WIndows 7 support.
Regards
Stefan

Mack Book Pro Stuck on Gray Screen

My Mac Book Pro is stuck on the gray screen. I have done the following
-Start computer using shift- nothing happens
-Started computer with option + R, when asked where I want to instal the Mac OS Lion it gives me two options Mac HD and Recovery HD but I cant click
on either because they say they are "locked"
-Started my computer by pressing option- attached a recovery disk I created- clicked recovery disk- clicked reinstall- clicked disk where I want it installed and it says- this disk does not use GUID Partition Table Scheme. Use disk utitlity to change the partition scheme. I CANT ACCESS DISK UTILITY!!!!!!
FYI I did create the utility disk using my MAC that has mountain lion on it.
HELP!!!!!

Safe Mode is not working, thus it's not a thrid party kernel extension file problem.

You mean command option r and that's Internet Recovery and it installs the OS X version that came on the machine, in your case it's 10.7, not 10.8, this is why you get the "Locked"
Obviously you can't install a older OS X version over a newer one or it's RecoveryHD partition without first erasing the ENTIRE drive (and losing all your programs and files)
this disk does not use GUID Partition Table Scheme. Use disk utitlity to change the partition scheme.
FYI I did create the utility disk using my MAC that has mountain lion on it.
You didn't correctly format the drive to be bootable first.
OS X can only be hold option/alt key bootable from GUID and OS X Extended Journaled formatted drives, then if OS X is installed by a OS X installer or cloned there to "bless it" to make it bootable.

Macbook Pro Stuck at Gray Screen When Entering Boot Options

Hello apple community,
I have a 15 inch MacBook Pro 2008, and I decided recently to replace the 250 Gb hard drive with a new WD Black 500 Gb hard drive. I backed up all the data onto my external hard drive and replaced the hard drive. Now I am trying to enter the disk utility to boot from the disk utility by holding the option key. When I turn on the computer and hold the option key it gets stuck on the gray screen. Does anybody have any idea why this is happening? Thanks.

OK. When you say it doesn't work does that mean you cannot see the drive in Disk Utility? Of course that means you need to boot from another drive such as your external backup. If you happen to have a Snow Leopard DVD to boot your computer then you could try with that. But there isn't much you can do if you don't have another bootable drive in an external enclosure or other form of hookup like a universal drive adaptor.
Your model is not new enough to use Internet Recovery. I don't know what more to offer. You cannot even verify that the new HDD is OK by putting it in an external enclosure.
