Macbook Pro (2010) stuck at blue screen on bootup

I recently wiped my hard drive and went to reinstall snow leopard on my macbook. It installed snow leopard, then it restored from my time machine backup I had. It booted up and asked me for a password. I didn't know the password to the account, because I never had one set up. I rebooted into the snow leopard install cd and reset the password. After rebooting, it gets stuck at the blue screen. I've tried to rewipe and reinstall twice so far, and don't feel like doing it a third time. I've repaired the disk, repaired the disk permissions. Anyone know how to make it boot up properly? Does the fact that my time machine backups are from lion screw anything up?

you really need to get the original disks. you can get them from apple for the cost of shipping. If the MBP is <1 year old, it is still under warranty.
You can try to boot it to safe mode: hold down the shift key while booting. If that does not fix it, then I would bring it to the Apple store or call Applecare. If the computer is <1 year old, but getting close, I would seriously consider buying Applecare to get the additional 2 years of warranty. If you are >1 year old, don't have applecare, and it is a logic board, it will cost you some serious $$$.

My macbook pro is stuck on grey screen with apple symbol in center with the progress circle under it continusly spinning. After I had turned it on. Prior to turning it on I had to force close and shut down a few hours prior. Please Help?

Unfortunately this means that there is a problem in the boot sector of your hard drive. It might be indicative of a fundamental corruption in the coding that allows your computer to boot your operating system from your hard drive. I had this problem twice and it resulted in me having to get a new hard drive and restore my data.
In other words, your computer can't talk to your operating system so you can't access your data.
Here is my advice: DON'T CALL APPLE TECH SUPPORT though they are kind and usually helpful it will take you an hour just to explain the situation and they will only tell you to do what I'm gonna say here.
First: Shut down your computer completely
Two: boot up while holding down the following keys: command, option, p, and r. The computer will reboot 3 times. This solution will likely fail so if you're frustrated skip to the next step.
Three: Boot up while holding down the option key. Select recovery drive. Select your default language. Select disk utility, click on Macintosh HD, and select "verify and repair volume." Likely the verification will produce some line like "unused node not erased." Or something like that. If anything using the words "node structure" comes up, you need a new hard drive.
If after verification and repairs you still can't boot I sincerely hope you have apple care because you will need a new hard drive. Set up an appointment to come in to the apple store, they will tell you to go and get data recovery, just ask them to give you the old hard drive. Unless you have an up to date backup in which case you can just restore from that. If you're lucky the only issue is with the boot sector which means that if you ask them to give you the old hard drive, you can buy an enclosure and you have effectively been given a free external hard drive. It still works to store data just not to load an operating system.
If you have a back up drive bring it to the apple store and they'll do the whole thing right there, it should take around an hour and a half but may take longer.
Hope this helps, it's annoying but it's your safest bet.
All the best.

My MacBook pro is stuck on white screen after shut down. Now, neither this is turn on nor turn off. I had to do

My MacBook pro is stuck on white screen after shut down. Now, neither this is turn on nor turn off.

You should be able to turn off your MBP by pressing the power button down continously for about 5-10 sec. When you reboot it you are going to want to enter into a terminal screen. Hopefully the following YouTube video helps: http://www.youtube.com/watch?v=qKOX72xNmbo

trying to update OS on 2011 macbook pro. stuck on purple screen

Ok. Do you remember what you were updating? Like Itunes or a security update. And did you let it complete and install? To install the update, it usually asks for your password and sometime asks you to restart. Here are some options to try. http://support.apple.com/en-us/HT203176

TS2570 after startup, my macbook pro goes to a blue screen and stays. this article says it won't work for the blue screen problem... any ideas?

My Macbook Pro stays on a blue sceen after start up. It won't boot into safe mode (holding down the shift key).
What do I do?

Hi Mindy, it may though, did you try it?
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

PLEASE SOMEONE HELP!!!!! My macbook pro is stuck on apple screen.

Hello,
Ok so heres the story, I have my friends macbook pro model#A1226. He bought the laptop from someone else. After having it a couple weeks (and it worked just fine, no problems whatsoever) we tried to install full tilt poker on it and relized that it had a password which would not allow us to download anything without having it (this is weird to me that we didnt have to have a password to access the whole system but just to install stuff, weird). At that time we did not have access to an operating system disk (we were told that for this computer its 10.5) and were told that we could re-install and that would reset the password. So.... I did something I should not have done. I looked up online how to bypass the password. I found a post, http://theappleblog.com/2008/06/22/reset-os-x-password-without-an-os-x-cd/ that told me to access terminal (on load up after "chime" sound to push apple+s) than type "mount -uw /" and hit enter. Than type "rm /var/db/.AppleSetupDone" and hit enter and than "shutdown -h now" and hit enter to restart. They said that this would create a new admin account and I would be able to delete the previous admin account with the password this way. Well....this may have worked except I typed the code in wrong, instead of "rm /var/db/.AppleSetupDone" I missed a space and typed "rm/var/db/.AppleSetupDone". After I typed it in wrong I still gave it the command to shutdown and when I restarted it loaded up to the grey apple screen with the thinky wheel thingy and was frozen there. It will stay like that for about 5 min and then restart itself and do the exact same thing. I found a friend who had the Mac OS X 10.5 disk and borrowed it from him but putting the disk in does nothing, I have tried pushing and holding the "C" after the chime and "C+ctrl" and no difference. Is there a way I can format everything through the terminal (since this is the only thing I can access) or does someone know a trick of some other code to type in to reset everything or did I fry the Hard Drive or what? And we dont care about saving anything on the computer, we just want it to work. Someone please please help. This is my friends computer and Im an idiot for messing with stuff I dont understand. I feel so bad. Thank you so much for your time, to whoever is so kind as to give me some of there expertise.

Hello c:
Welcome to Apple discussions.
Your post was hard to follow, but, for openers, very few people should EVER use terminal commands. As you have found out, you can screw a system up badly.
So much for the lecture.
OS X requires a system administrator password when anyone tries to install software that will affect the operating system. This is an Apple security feature that keeps people from, hopefully, doing dumb things to their system.
You cannot use a "friends" disk on a system that differs from your own.
Bottom line, you need to reinstall the operating system (whatever came with the system). If it is OS X 10.5, you could do an archive and install.
There is no way that I know of to undo the damage caused by entering the arcane terminal commands.

New MacBook Pro gets stuck on blue start up screen

Hey all. I just got a new MacBook Pro in the past 2 weeks, it had been working fine, but last night I turned it on, it went to the bluish apple screen and did the loading thing, but wouldn't get past it. I let it do this for about 20 mins while I did other things, nothing happened, it wouldnt get to the login screen. All it did is get pretty warm to the touch on the bottom of the computer.
Any ideas?

pstumba,
Welcome to Apple Discussions.
You can try a SMC reset simultaneously hold down the Left shift, Left Contol and Left Option buttons and Power button for a moment. Then restart the computer.
If that still doesn't work, shut down the computer and wait a moment then restart while holding down the Option and D keys which will force the computer to start from the internal drive.
If that still does not work then try inserting the install disc that came with the computer and restart holding down the Option key, then choose the Startup disc when it asks which startup volume to use. You should then see the language choices, choose your language and then from the Utilities Menu choose Disk Utility. In Disk Utility check the S.M.A.R.T. status of the internal drive it should indicate "Verified" if it is OK. If it does not then choose Repair Disk, you may need to run this several times until the drive appears OK. If it still fails then you know your internal drive failed and you have a valid warranty claim. Simply call AppleCare (look in your manual) or make an appointment at the Apple Store you purchased it from to arrange for a repair.

Roger

Macbook Pro boots to a blue screen. Only boots in safe mode

Hi, I am a long time reader, first time poster.
OK so I just go a new Macbook Pro 13' from my school (my school made it mandatory to get a mac this year) and I was installing some of my applications. Then I got the "You need to restart your computer" message. I restarted, and all i got was a blue screen with my pointer. Then after a while it says the same restart message. Also I have tried booting from the Snow Leopard Disk, but I get the same message before the actual SL installer comes up. I have been able to get the Macbook to boot in safe mode and I repaired permissions and the disk, however that does not seem to help. I have also reset the PRAM and that did nothing. I am running out of ideas... how can I fix this?!? Help!

You should not be having kernel panics on a new Mac. Kernel panic causes is sometimes hardware related. Your computer is still under warranty since it's new. You can either call Apple tech support or try the suggestions mentioned in User Tips: Kernel Panics and this article - http://support.apple.com/kb/HT1392

Hey, I recommend backing up all your files manually via USB hardrive and then format your mac's hardrive, here's a link for instructions on how to format your mac's hdd: http://computers.tutsplus.com/tutorials/how-to-format-your-macs-hard-drive--mac- 53986
Also I recommend downloading the latest Mac OS X via the app store. The reason why I've recommended to back up all your files and programs manually and install a clean and new os is because when you put your data on manually, you significantly reduce the chances of the problem happening again and it looks like you have something inside your os that's slowing everything down. You'll also have the latest updates and support if you download the latest mac os x. You should also back up your Mac via time machine as well so you have a image of your OS. I recommend installing a SSD drive inside your MacBook as they make a huge difference in performance, your computer will preform almost instantly, it only takes 7 seconds for your mac to boot into the os and everything else you do is pretty much instantly. They can be a little expensive but they're coming down in price and they're with it! http://www.amazon.co.uk/Crucial-CT480M500SSD1-2-5-inch-480GB-Internal/dp/B00BQ8R HJ2
I've had the same problem before and I hope that helps.
Good luck

Have you tried using Paragon's Tech Suport? If you install software that renders you computer unusable, you should talk to that vendor, first. Most people helping out here have probably no need for that software and would have no idea how to fix the problems it caused.
Sounds like their installer corrupted your system files. This page discusses a blue screen problem after installing 10.5. If you can find out what Paragon installed, you may be able to use option A or C to remove it.
You also may be able to boot into Safe Mode (hold down shift key while it starts up). It will take a long time to boot as it runs a disk check first. Again, once in safe mode, you may be able to remove the software and make the machine work again.

HT203176 MacBook Pro is stuck on gray screen with spinner & won't proceed to login screen

MacBook Pro is stuck on Grey Screen with "restricted" symbol.

My MacBook Pro fans were loud and unusual, so when I looked up what to do on google most of the results told me to reset the SMC. So I did that, expecting it to work, and now my MacBook Pro won't go past the Reboot screen! The strange thing is, it doesn't stay on the Apple logo like most people say. Instead, the apple logo changes into the "Restricted" Symbol and just stays there.
I assumed it was part of the SMC process so I left it alone. But it's been happening for hours now. I even restarted it several times and it still stays with the Restricted sign. I tried redoing the SMC process and I even tried resetting the PRAM. Nothing has worked. Pressing Command-S or Command-R doesn't do me much good either. I'm worried that something went wrong with the harddrive and I cannot afford a new Mac or the repairs for it.
Can anyone help me?

This is usually the remedy for out of control fans.

Ok, it's not booting up to OS X, which when loaded will control the fans to settle down, but the default if OS X doesn't load is eventually turbo mode.
You have basically what's called a "gray screen issue"
