Macbook pro hangs on blue screen at startup

I've been having intermittent problems with my Macbook Pro starting up, but this is the first time it's completely failed to start up: I get the startup sound, the grey screen with apple logo, and then it just hangs on a blue screen, with a grey startup dial, and nothing happens. It was working fine up until this evening; it's confusing to say this, but it seems to have moods where startup is an issue. But I have taken it in several times for this very problem: the first time, they replaced my hard drive, the second I was told to reinstall OS X, and then add software back one program at a time. All I had on this machine was Adobe Creative Suite 4, nothing which would cause any issues. I don't even have any fonts on this machine!
Desperate to know what might be the problem; I've tried a few of the basic troubleshooting work arounds and none of them are working. Does anyone know what the issue could be?
Help!

If you get a external USB or Firewire drive, you can hold c and boot off the installer disk #1 that comes with your computer, the second screen in is a Utilities Menu and Disk Utility.
Select the EXTERNAL DRIVE and Erase, format HFS+ Journaled GUID partition.
When that's completed quit Disk Utility and your back in the OS X installer, install OS X on the EXTERNAL DRIVE.
When that's complete quit and reboot hold down the OPTION KEY and select the External drive to boot from.
Now GRAB THOSE FILES!!!
After that you can do what you want to the boot drive, if you can't fix it, you can always install OS X again (without formatting) and it should leave your programs and files alone. But if something goes wrong you have a copy on the external drive.
You can choose to Disk Utility format and reinstall everything, OS X, programs and files as well.
If for some reason you can't access your internal drive, either booted from the install disk in Disk Utility or via the external drive, it's possible your hard drive died.

MacBook Pro hanging with blue screen and spinner after installing Software Update

Hi I was wondering if someone could help me with this current issue. Just a few hours ago I finished reinstalling Mac OS X Snow Leopard in my MacBook Pro. I performed a clean installation as part of a yearly spring cleaning that I do on all my systems to keep them optimized. So there was I downloading some software updates which included the combo update of OSX 10.6.8 and others. The updates finished downloading and the system logged out to install the updates, when the updates finished installing my MacBook proceeded by logging out into a blue screen and show a gray spinner similar to the one seen when you start your Mac. Here's the problem after 2 hours the system is showing the spinner and the blue screen, I think that my computer has just hanged in the reboot process.
I was wondering what should I do? Do a force restart? Or leave it overnight?
Also, where can I find any information on what error is causing this issue?
I appreciate your responses and help.
By the way, I installed Mac OS X from a USB stick that has the original image of the disk installer that came bundled with my computer.

Force a shutdown. Do not restart yet, but first do the following:
Repair the Hard Drive
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, 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.
Next, boot into Safe Mode then restart normally.
Hi Kappy,
Checked the hard drive after forcing a shutdown and booting from my Snow Leopard Installer USB Key and the status of the HDD says "Verified". I ran the repair and the volume was repaired successfully. Clicked on "Verify Disk" and it says "Macintosh HD appears to be OK". So I ran a second repair and again no errors were reported.
As suggested I booted back again in Safe Mode and restarted normally. All software appears to have been installed successfully. But I don't understand why my computer hanged and showed the spinner after installing the updates in the blue screen that appears just before rebooting. I am aware that the system shows that spinner after a OS update but the longest it lasts is 30 seconds at the most in my previous cases.

Yosemite - MacBook Pro: Boot loop/Blue screen

Hi, I've been running Yosemite on my MacBook Pro for about a week now, then while using it yesterday the screen randomly went blue with black lines through it.
At the time I was playing a beta version of Football Manager 2015, so I thought that it was an error with the game. I forced a shutdown and left it for a minute or so. I turned it back on and now it continues to reboot itself during the status bar on startup (after about 40%).
I have already tried a couple of solutions:
Command + R: Blue screen
Command + Shift: White screen freeze during status bar startup
Option key: brings up Recovery but after clicking that the screen goes blue.
Command + Option + P + R: Still reboots. No change
Any suggestions/knowledge would be greatly appreciated.
Thanks.

I Have the same problem. Did you find a solution .

MacBook Pro gives a blue screen when I try to start from a bootable usb stick

Since yeasterday my MacBook Pro is refusing to startup. The starup proccess goes like Apple Logo, Spinning wheel, white dispaly and stops - freezes there.
So I made a bootable usb stick and tried to boot from there so to be able to do a format and repair it. Also the recovery HD wont boot...
When I start my Macbook Pro from the bootable usb stick it gives me a blue screen. I have tried to reset PRAM but nothing.
I am attaching 2 images of the blue screen.
Please help...!!!

Guys thank you for your replies. I could boot in any way... I tried several things.
Finally a friend managed to give me an Apple Hardware Test and it came with these results... Any ideas ?

Mid 2010 MacBook Pro: Will randomly blue-screen and Safari repeatedly crashes.

I bought my MacBook Pro in June/July of last year, and it has worked perfectly fine up to this point. However, for the past 2 months or so, my computer will randomly go to a blue screen and log me out. Also, Safari will crash several times (it had never crashed on me until the blue-screen problem started. Both of these issues surfaced at the same time). For the most part, the blue-screening problem only happens when I'm using the internet, but sometimes it will happen when I am offline as well. This is an infrequent/inconsistent problem, though. It will blue-screen and Safari will crash one week, but then it will be perfectly fine for the next three or four weeks. What's wrong/how do I fix it?

Hi JRC8.8,
It sounds like you have been on the right track in trying to troubleshoot this issue. You may want to see if your MacBook Pro will boot directly to the Apple Hardware Test, as outlined in the following article:

OSX Server Hangs on Blue screen at startup

We have an Xserve Running 10.5.8. We have been having strange issues for some weeks with client's logging in and their desktops being missing. Last Friday I noticed that the backup was not running correctly and I had a student who had lost her work mysteriously too. I decided to restart the server to see what would happen. On restart I cannot log in to the server either remotely or locally because after the white apple with spinner screen the machine goes to a blue screen with no login window. Services are up and running, I can view and use Server Admin and Workgroup Manager, and I can ssh into the server. I have trawled the internet in search of answers but all to no avail. There are some errors in the log but I am not familiar enough with these things to know which are significant to this problem. To further complicate matters the OSX server disk is nowhere to be found, hasn't been seen since well before I arrived on campus. I have ordered Snow Leopard for this machine but would like to get to the bottom of the issues.
I have booted into safe mode from ssh but this has made no change to the situation. I am relatively new to comand line management of macs so please don't assume I know how to use it like an old pro. I am learning rapidly.
Thanks

Macbook Pro stuck at white screen on startup. HELP!

Right when i turn on my macbook pro, it plays the startup sound and gets stuck on the white screen. I can hear it running my cd right when the computer starts up. no matter what i do, i cannot get out of the white screen. it just stays there. same thing every reboot. Whats going on???
HELP ME!

Hi, I had this exact same problem with my 15in mbp just before Christmas. I shut it down one afternoon, and then later in the day switched it back on. It wouldn't boot past the white/grey screen. It wouldn't even get as far as the apple symbol. I tried to start it up several times, but to no avail.
I called up apple support, and they had me run through various keyboard combinations at start up. Nothing worked. According to my observations and the apple telephone operator's knowledge, it was as if the keyboard wasn't booting up at all during the startup sequence, hence it was not responding to the key combinations. There was no fix available over the phone and the advice given to me was to take it to an Apple Store to have the keyboard replaced. Living in Prague Czech Rep, as I am, there is no apple store, only one reseller, which I resolved to take my mbp to the next day.
However, before the night was up, I decided to to do one more thing. According to my (less-than-Vulcan) logic, since I was taking it to be opened up, and knowing that since the dawn of time, hitting machines has seemed to give them a new lease of life, I decided to see what a sharp thump to the side of the computer might do. It wasn't overly forceful, just enough to make me feel satisfied. Would you believe it, the **** thing started up the next second I pushed the power button!
Well, I had many weeks of uninterrupted, blissful computer use until a few days ago. If you haven't heard, quite a few mbp users have been reporting cases of unresponsive keyboards and trackpads whilst running leopard, leading to kernel panics and I have now unwillingly joined their ranks. I am in no way an authority on computers (I think that's rather obvious from my repair technique mentioned above) but I have a suspicion that my little episode last Christmas is related to the current issue of the internal keyboard and trackpad becoming unresponsive, so I'd watch out for that in the future once you're able to get your laptop up and running again. There doesn't seem to be much information as to why this is happening, but for my part, I've found that it's more frequent if pressure is placed underneath the battery, and less frequent under Tiger than Leopard.
I really hope, you're able to get your mbp up and running again. I know how utterly frustrating it is when it's not working and you have no idea why.

Hangs on Blue Screen on Startup

Hi all. I know there are similar posts to mine, but my questions can not be found so far in my searches.
I have a 2009-ish refurbished Apple Store MacBook Air with a SSD.
Today I restarted my computer, it seemed to be running a bit hot and slow. After rebooting I could only get it to get to a blue screen and no desktop. Computer boots normally with grey screen, apple logo and gear icon... following which I get a blue screen, sometimes with a gear other times with no gear or an alternating with/with out gear on blue screen. Screen never goes to desktop screen but momentarily there appears to be a single pixel square (or possibly a 4 pixel square) of white near the upper left corner that appears momentarily over the blue, then gone.
After searching I have tried the following things...
Tried booting in safe mode (holding down shift) with same results.
Tried doing a PRAM reset with same results.
Tried booting in verbose mode with same results.
Tried booting in single user mode and did the following:
ran fsck -fy and disk verified with no errors, however it did indicate that something had updated. rebooted with same results.
again ran fsck -fy multitple times with no errors, rebooted with same results.
ran mount -uw, disk reported it was HFS read only journaled... changed drive mount to -o for read write sucessfuly, then ran fsck again and rebooted with same results.
So according to fsck the drive is fine, but if I reboot and then try mount -uw again, it again shows as read only. I am not sure if this is normal or indicates there is in fact a hard drive problem. Or perhaps there is a bigger issue.
I do not have a usb CD Rom drive to attempt to boot from OSX Snow Leopard disk in order to test further, I am stuck at the moment. I do have another laptop and a MacMini which I could potentially use to share a CD over WiFi, but I am unsure if I can boot from a shared CDROM via wifi and if so how to boot into that mode.
Does this sound like a drive issue or potentially something else like a virus or motherboard or graphics card failure? Thanks in advance for your time and efforts to answer this question.
bk

Update: Using Remote Install I was able to remotely boot my mac from another laptop's CDROM drive and run Disk Utility from the installer which again passed with out errors like the fsck command. I also repaired disk permissions. Upon reboot to the internal SSD, I am again getting the same blue screen.
So, since I can boot remotely and my disk seems to check out ok I am guessing now that there is something wrong with my OS, some kind of corruption has occurred, but that is just a guess. It is possible I guess for there still to be an actual hard drive or hard ware failure of some kind.
Any help is still appreciated.

New macbook pro 17, gets blue screen after sleeping

Had it for 1 or two months and haven't had any problems. Was just using it and closed it to sleep, and reopened it and it was stuck on the blue screen.
Safe mode won't work. Resetting the PRAM won't work.
What the heck?

Hi,
A flashing question mark appears when you start your Mac
Hopefully something will get your Mac running again.

MacBook Pro hangs in gray screen after security update

I just allowed software update to download and install the latest Safari update and Security update 2009-6. During the restart my macbook just hung on the gray screen with the spinning gear.
I've tried starting in target disc mode but the iMac doesn't register the MacBook's HD.
I started from the install disc (10.4.5) and launched disk utility but it won't read the HD either.
I tried Safe Start-up, resetting PRAM but still the hang.
HELP

If not for the coincidence of a restart after those software updates, I'd say
you need to get a correct version of Disk Warrior and see if it can repair
or rebuilt the hard disk drive's Directory; since that is a likely item to have
been corrupted somehow. And corruption of data, including the System,
is a serious matter. A near-capacity or over-full hard disk drive can cause
odd issues including corruption; so there may be more going on in the Mac.
Other third party disk utilities may be able to help get into the failed computer
and the problem is likely the hard disk drive. Sometimes, a software issue in
a drive can related to a hardware failure; so to consider a strategy that may
include a new drive for the computer and an external enclosure for the drive
that is now in the failed computer, to then maybe further your recovery of data
if it comes to that.
Good luck & happy computing!

MacBook Pro freezes at blue screen after the grey start-up screen.

I was installing the latest updates including the os x. But my mac froze while it was doing so. And now when I try to start my baby up, she freezes after that first grey screen with the logo on it. (Sometimes the power-button won't even take any effect at all, no matter how long I hold it down or whatever)
Please help.

hi there--
the first thing you need to do is to try a safe boot. do this by holding the shift key during startup until you see the spinning cog under the apple. keep in mind it can take up to 10 minutes or more to go into safe boot. if you get into safe boot the first thing i would do is open disk utility and repair permissions. then i would try for a normal restart. if it still doesn't work, do another safe boot and remove items from /library/startupitems folder and from system preferences > accounts > login items. and then restart the computer. if that doesn't work or there is nothing for startup items or login items, try removing the com.apple.loginwindow.plist and restarting the computer. also, try booting to the install disk and running disk utility. http://docs.info.apple.com/article.html?artnum=106214. if none of these things work, then try a pmu reset. http://docs.info.apple.com/article.html?artnum=303319. hope one of those things works for you.

Reinstall OS X:
Reinstall Snow Leopard 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/.
OR:
Reinstalling Lion Without Erasing the 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 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.

My MacBook Pro has been having difficulties at startup. It sometimes locks and doesn't get past the white screen. It has also locked up several times and gotten a green stripes across the entire screen. What is causing this and how do I fix it?

You don't, take it to Apple for repair.
This might interest you if it's too old to fix.
My computer is not working, is my personal data lost?
