My macbook pro went from startup screen to grey vertical stripes

my macbook pro went from startup screen to grey vertical stripes with a bit of flashing. Force quit twice and it is still doing it. Had a bit of problem last time I started it with flashing screen, but it settled. After leaving it on screen went black (as usual) and on waking had desktop up but continued to flash. Any suggestions?

MacBook Pro frozen on startup screen with progress bar and then it turns off

Hello, I have a MacBook Pro 15" of early 2012 with a i5 Intel, 4GB of RAM and a 500 GB HD.
I was installing the new suit of Adobe, when suddenly my Mac got frozen, vertical coloured lines appeared and the image on screen went distorted. I had to reboot the Mac by holding the power button until the screen turned off and when I turned it on, the lines appeared again and it itself automatically rebooted. Then the screen (now with no vertical lines) got frozen on the startup grey screen with the apple logo and the spinning wheel for hours with no response.
I tried to follow the steps of the official mac forums like verifying the HD with CMD+R and then Disk Utility, it says everything's fine; the same happens with CMD+S, no errors. I reinstalled Mavericks with the same CMD+R. I already reset the PRAM, SMC and performed a Safe Boot staring up in Single user mode and Verbose Mode and nothing, the same startup screen. I made too thins thing of holding shift until the progress bar appeared. Three days later (Today) I repeated the steps again and finally the verbose mode. Now, when I turn it on, the startup screen appears again (Apple Log and spinning wheel) with a progress bar. When it completes, the Mac turn itself off.
if you can help me, please. I don't know what else to do. The last thing is technical service.

Hi again ggt15,

Macbook Pro stuck at startup screen.

I've ran Disk Utility, there were problems that were fixed, but it's fine now (I've ran it again to double check), and I've ran Apple HHardware Test and I received" no trouble found".
But everytime I try to start up it gets stuck on the grey startup screen with the apple and the oration under it. So I'm at a loss at this point.
Thanks for any help you can offer.

System files are missing or damaged so you need to reinstall OS X:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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 Utilities menu. 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.
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.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.
If you have an earlier version of OS X installed then do this instead:
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, 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.
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.

Brand New MacBook Pro stuck on startup screen after Lion os X update

I literally got it an hour ago and when it was updating it got stuck on the startup screen. I've tried turning it off and on but it still wont load. Help

Macbook pro crashes after display is full of vertical stripes.

hello all.
I have a 2.2Ghz intel core duo 15" macbook pro, with mac os 10.4.11, bought in July 2007. never had any issues since.
about a year ago, i upgraded the RAM to 4G, no problems.
and then yesterday, it started happening. Crashes like i'd never seen before, the screen locks, vertical blue stripes on the display.
Have to force a reboot, and the second reboot usually doesn't work, i get the international message telling me that I need to reboot again.
then it boots up again, only for a little while.
the crashes happen at any moment, not using a specific program, can be while browsing with firefox, using VLC, using openoffice, anything.
I tried the disk utilities check up on the hard disk, and it was fine.
I did all the mac osx updates, but it still crashed.
I tried a clean of all caches etc with Onyx, but the problem persisted.
I tried zapping the PRAM, but it still crashed.
I tried removing the extra RAM i'd added a year ago, but it still crashed.
I booted on an external firewire 800 HDD i have with a backup system, but still got the crash...
seems to be the video card...
this couldn't have come at a worst time for me, as I'm currently flat broke AND with work to do.
I really really hope this can be fixed without having to send it to repairs.
here's the crash log :

i think the current kernel panics are related to the logic board changes after the nvdia graphic bug... any clues as to what errors
4MEM/9/40 000 000 : bc13950
error
4MEM/9/40 000 000 : 6b506C4
might be ?

When my macbook pro wakes from sleep the curser is not there, no keys work and the screen is frozen so i have to reboot it

Sometimes when my macbook pro wakes from sleep the curser has disappeared, the screen is frozen and no keys work. I have to reboot.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. 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. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
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. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Hi I wanted to let you know that the hard drive is bad I am meeting with the apple manager tomorrow since my laptop is no longer under warranty but I had previously brought the laptop in for the same black screen when the warranty was good.. Have any pointers on how to approach them ? I'm seriously disheartened by this especially since my 2006 white MacBook is running like a champ with no problems ever which is why I decided to buy another MacBook but one that was capable of running Lion

After updating to Lion my macbook pro does not startup, it is stuck to the grey apple screen

TS1365 My MacBook Pro will not startup. At all. The suggestions from Apple Support are not helping. At all. Someone help?!?

My MacBook Pro will not startup. Its not responding at all. Does anyone have any suggestions on how I can correct this?

HI Catherine,
First, make sure it it shut down by holding down the power button for 5-10 seconds. Plug in the power adapter. Press the power button and hold down the shift key to see if you can start in Safe Mode.
If the power adapter and/or battery are known good, the next thing I'd check would be the RAM to make sure it is securely seated. If batt and/or power adapter are questionable, then you'll want to find one or both and try them out; if you don't know someone with a similar MBP, this might be most easily accomplished by making a free appointment at an Apple Store "genius" bar.

My Macbook Pro has a black screen when running in Bootcamp Windows 7. Since I updated the mac side my windows side now starts up with completely black screen - no prompt, nothing, Cap keys still light up as does mouse and DVD drive seems to run.

My Macbook Pro has a black screen when running in Bootcamp Windows 7. Since I updated the mac side my windows side now starts up with completely black screen - no prompt, nothing, Cap keys still light up as does mouse and DVD drive seems to run.
Will not show up in safe mode, will not show when started from Windows 7 DVD.
I suspect the Mac update wiped out my PC video drivers but can not think of a way to re-install?
Can see the PC volume from Mac side with files.
I've looked at all the online solutions so far and have tried most of them without success. Please help!

Specifically, the posts by Dunsany and valkyr did the trick. I booted in safe mode, uninstalled and deleted the Nvidia driver, disabled automatic driver installation, and restarted normally. I then manually downloaded and installed the previous Nvidia driver for my graphics card (which at the time of this writing was 335.23, rather than the latest which was 337.88), and everything is now bueno!
Two hiccoughs along the way: First, when I tried to uninstall the Nvidia driver the first time, when I restarted I got the login screen (which was a good sign), but it quickly went black again. I powered down, restarted in safe mode again, and repeated the uninstallation process, and it worked the second time. Second, when I started the manual install of the 335.23 driver, the computer played a sound similar to the one for disconnecting a USB device, and the screen went black. I'd seen a lot about trying to increase the brightness (though it hadn't worked up to this point; but if you haven't tried it yet, might as well); I tried it, and it worked! So far I'm back up and running. [/fingers crossed]
Hope this helps someone else!

Macbook pro will not boot even to grey screen ??

Macbook Pro retina display gray screen on start up

New Macbook pro 1 week old gets a grey screen on startup
Tried to do a safeboot but it stops after 5 lines.
any ideas???

You have a Retina model MBP. It did not come with installer discs. You would use Internet Recovery:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
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 Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

MacBook Pro update at startup not working properly rendering MacBook unusable.

My MacBook Pro loads an update at the grey screen then shuts off. When it turns back on it attempts to finish loading the update again. Is there a way to stop this update from happening at the startup screen at this time?

tye91,
you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it reach the login screen now?

My 13" MacBook Pro freezes at startup

While using Firefox, my Macbook pro frooze about 2 days ago. The screen was only showing the multi-colour spinning circle.
Pressed [Command + Option + Esc] to force quit. No response
Pressed Power Button for 10 sec.Power OFF
Again Pressed Power Button, the MacBook Pro freezes at startup, the MAC makes the startup music, enters a white Screen and is stuck there. There is a light clicking noise continously heard.
Followed instructions to RESET SMC.
1. Power OFF.
2. Press [Shift + CNT + OPT + Power Key] and release at same time.
3. Power ON.
There was no response.
Attempted multiple times to switch-ON and OFF MAC-Book. No response
Attempted RESET SMC multiple times. No response.
Then suddenly when I gave up, it unfreeze after 15 minutes and enters the login screen.
Did a normal shut-down and power up. It was OK.
Then, ran the Firefox in debug mode and disabled the plug-ins.
It was stable for a 2 hours.
Then again, got the spinning colour circle.
So, took it to the service center last afternoon here at North Point, Hong Kong. The engineer there instructed me to backup the hard-disk and recover the CD.
Brough the machine back to my home.
Since the spinning colour circle would not stop, powered OFF the device.
On POWER ON, the screen freeze. Just like the first time.
Tried RESET SMC, Nor esult. Left the device power-on for an hour. No result.
Then, inserted the recovery CD. Powered OFF the Macbook Pro. Powered ON and pressed "C" immediately. No response. The CD is now stuck inside the MACBook Pro.
Still have the white Screen at Power-On.
