Macbook Pro Won't Boot After Starting Lion Install

2008 Macbook Pro 17" with Core 2 Dou processor.
Internal Disk has two Partitions
Downloaded Lion from App store and ran installer. Selected 2nd partition which is Mac OS Extended Journaled. (I was intending to do a clean install on this empty partition.)
Installs appears normal, goes to boot and hangs at the gray screen after the chime.
Verbose logging does not show anything obvious, no more info after identifying the network adaptors.
Booting with option key does not give option to boot to Snow Leopard partition.

MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear.

MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear. Computer won't even start in safe mode.

My daughter's MacBook Pro was doing exactly the same thing. I don't know if it had anything to do with the latest update. She called me about a week ago saying that her MacBook began running slower by the day . She then called me Friday and told me that it wouldn't get past the gray screen and the gear just kept on spinning. I did everything I could over the phone including Safe mode which it wouldn't go into and thought maybe it was the hard drive. She took it to the Apple store. Originally, they also thought it was the hard drive. It ended up being a corrupted operating system (Lion). Apple genius simply re-installed Lion and she's back up and running. Good thing she backed up right before it crapped out. She'll be restoring everything tonight. Don't know if re-installing Lion will help your situation, but it did the trick for my daughter.

Macbook Pro won't boot after Mountain lion upgrade

I bought the Mountian Lion upgrade and it installed fine on my MacBook Pro, and the machine worked fine yesterday. I performed a normal shutdown, and today it won't boot up. The Apple logo and the spinning pinwheel is all I get. Is there a known issue?

Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

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, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Macbook Pro won't boot after update

I have a macbook pro3,1 (early 2008) that I received from someone else. When I received it, it had os x 10.8.3 installed. Initially I tried to update it to maverick, but after it rebooted it would not boot, just continued to reboot over and over. I then was able to boot into restore mode and do a repair on the disk. After that I was able to boot into 10.8.3.
I decided to update to 10.8.5, and received the same results as before. This time I was unable to restore with a disk repair.
I also created a bootable usb with Mavericks on it. Again, it will not boot to allow an install.
I was able to boot into safe mode, but that did not fix the installation. I tried repartitioning the hard drive and install mavericks on the new partition, but that failed also.
After looking at the logs, I see that there is a kernel panic that happens. Everytime I boot normally, it seems to get just before the login screen before it reboots. Below is the log.

I received the macbook from someone else without installation disks. Also, when try to do a re-install of 10.8.3 from the internet in restore mode, it tells me that the account does not match the one the purchase was made from. I would rather not run 10.8.3 anyway if I could install mavericks.
Below is the system information for the macbook
Hardware Overview:
Model Name:          MacBook Pro
Model Identifier:          MacBookPro3,1
Processor Name:          Intel Core 2 Duo

I have tried to reset nvram as well as smc with no result.
I have also done a extended apple hardware test which found no errors.
The macbook does have a bad battery, so I have tried booting without the battery. The results did not change.
I have searched the internet for the kernel panic error and can not find a consistent issue for macbook pros. Some say it is a hardware problem. Others say it is an install problem. What does not make sense to me is if it is hardware problem, why was I able to restore it back once and get it to boot consistently. It seems to be directly the result of updating the software.
I also read that 10.8.5 consistently had boot problems upon install, so I tried re-installing the combo update for 10.8.5
I feel like I have exhausted almost all the resources except taking it to the genius bar.
Please let me know if you can help.
Thanks,

bereanmh,
since your MacBook Pro didn’t originally have Mountain Lion installed at the factory, the former owner erred in leaving it on its internal disk when transferring it to you; Mountain Lion is non-transferable when sourced from the Mac App Store. The former owner should rather have provided you with its original pair of grey installation discs, which hold its original version of Mac OS X, its iLife apps, and its model-specific Apple Hardware Test. If you didn’t receive these discs, you can contact Apple directly to purchase a replacement pair. (They’re not available in Apple stores.)
That being stated, regarding the panic report above, the prime suspect is that NullCPUPowerManagement kernel extension — try uninstalling it to see if that makes a difference.

MacBook Pro Won't Boot after Firmware Update

So I just upgraded to a MacBook Pro which came in the mail yesterday. I removed the Apple-installed HD and swapped it out for a bigger, faster HD. I installed OS X from scratch, imported everything from my Time Machine backup during the Setup Assistant, and then started installing updates. Everything was running swimmingly until the last updates.
What happened is when I rebooted my MacBook Pro and logged in after a series of updates, I got presented with both a Bluetooth update and a Firmware update at the same time. Both required a restart so I thought I would kill two birds with one stone. I installed the Bluetooth update, and then when it asked to reset I installed the Firmware update instead. However, the firmware update didn't behave as advertised because instead of shutting the MacBook Pro completely down, it restarted and then started installing the firmware update.
Ever since the firmware update (which I think installed correctly but don't know how to verify), I cannot boot my MacBook Pro. Using the OS X install DVD I can view my firmware version using System Profiler, and the number it is reporting is MBP53.00A.B03.
I have tried booting in verbose mode to try and get a feel for the problem, and it eventually hangs on an infinite loop saying something about not being able to find something on disk0s2.
I also thought I would fix the problem by doing an Archive and Install, but it quit at the very beginning of installing with the error "unknown error".
Also I thought I would format the disk with Disk Utility and then try installing again, but Disk Utility reports that it in unable to unmount the volume.
Any help you can provide would be greatly appreciated. Thanks!
-- Update --
Remember how I'm unable to unmount the drive? I force unmounted it and then used Disk Utility to repair the volume, but still no luck.
I think the key to the problem is this new HD I put in runs at 3 Gbps. I think I read somewhere that the new MacBook Pro's don't support that.
I think next I should try swapping out the new HD in my MacBook Pro with the one it originally came with. What do you think?

I, too, have a brand new MBP 15" that I put an Intel X25 in. At the 1.5 (Prior to Firmware Update) setting, it worked fine. I rant the Firmware Update, all looked fine, but the drive is no longer able to be seen.
Flash the PRAM, per other suggestions to no avail. Boot off of the DVD and disk utility nor Profiler sees the drive.
Replace the drive with the stock that came with the MBP (which I had never even used) and it works.
Put the Intel X25 into a Windows machine and it works fine. Reformatted it (in windows) and put it back into my MBP. Still not able to see it (from the Disk utility after booting off the DVD).
Intel's firmware for the drive says its up-to-date (new drive) and if I attempt to "re-run" the Mac Firmware Update, it says that the machine is already up-to-date.
Seems odd that it worked before an now it doesn't. Also seems odd that the X25 works in other machines. And that my MBP works just fine with the stock Hitachi 7200 320GB drive.
Ideas? Intel says to call Apple Support. Not sure what I can say to them.

MacBook Pro won't boot after 10.6.8 update.

I completely erased my hard drive, reinstalled Snow Leopard and updated to 10.6.7. I then performed an Apple Hardware Test and verified the disk using disk utility. Both tests were successful. I then updated to 10.6.8 using the combo update and restarted my MacBook Pro. The boot process ran fine until the system locked up on the bright blue screen. No peripherals were connected to the laptop during this process. I powered the laptop down using the power button and turned it on again. This time, I entered verbose mode. The last line of text that I see before the screen turns black is "[ PCI configuration begin ]". Can anyone assist me with this issue?
My System Profile is as follows.

Might be time to replace the PRAM battery. That's not the normally accessible battery, but it is one that often fails after 4 years.

Early 2008 MacBook Pro won't boot after Lion 10.7.1 update

My 2.4 GHz 4GB RAM Early 2008 MacBook Pro wont boot after downloaded the Lion 10.7.1 upate. Upon restarting the screen went dead and now the system does not boot, as if the bootloader has been wiped out. Screen appears dead but was known to be working before hand. The hard drive spins up but doesn't sound like it is searching for data.
Can anyone help me?

Okay, I tried everything I can think of last night. I removed every startup process and every tool or programm that goes deeper into the system (GlimmerBlocker, LittleSnitch, Parallels). Cleaned Up every Cache I could find and refreshed every necessary Cache or Database possible. Took me a couple of hours. But still no luck - the machine doesn't boot, just in safe mode. Right now I copy all my personal stuff to a new external harddrive because TimeMachine doesn't work, after this I will do a clean install of Lion.
It's not hardware related, it's the 10.7.1 update that doesn't work properly. By the way, the only errors remaining are:
WindowServer - kCGErrorFailure
ManagedClient - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
SecurityAgent - kCGErrorFailure: CGSPackageGetWorkspaceType: couldn't get workspace type
and a lot of:
com.Apple.SecurityAgent.00000000-0000-0000-0000-0000000186A7: CoreAnimation: rendering error 506
that's also the last one I get before the system hangs…

Macbook pro won't boot after update to 10.6.8

Hi everyone,
Yesterday I bought an used macbook pro (15 inch early 2008). When looking at it, it was in good shape and the previous owner just did a fresh install of snow leopard. I took it home and whas happy with it. In the first two hours of using it, everything was fine. After installing the update to 10.6.8 my macbook needed to be shut down.. After shutting down it started up again but the screen stayed black. I had no idea why. So I rebooted it by pressing the power button. The same problem remained, it seemed to start up (I could hear the harddrive and fan) but it didn't boot into Mac Os. After a couple of attempts, it now shutsdown immediatly after pressing the powerbutton (3 seconds after). No chime or nothing.
At first I thought this would only be a software problem, because the problem started immediatly after updating. So I put in my snow leopard dvd to boot into that, but I can't even get it to boot into the install dvd. Because it shuts down immediatly after pressing the power button. Then I started suspecting an hardware failure, which would be a very big coincidence to show up immediatly after booting up. These are the things I have tried so far, to no avail:
- Plugging of the power cord and removing the battery, then pressing and holding the powerbutton for at least 5 sec
- Holding the option, command, P and R keys during boot.
- Replacing the memory
- Replacing the hard drive
- Unplugging the super drive
- Starting up holding the d key
At a certain point I was hoping that It would be an harddrive or memory problem. I replaced both with examples I know for sure they are working. But still the same problem; macbook shuts down almostimmedialty after pressing the power button.
There is no warrany anymore, and technical support would cost me 49 euros per incident.. to probably hear that the macbook is beyond repair. I feel i have just thrown away 300 euro's for an nightmare experience. Does anybody now anything to try, i'm really desperate here

After installing the update to 10.6.8
What update was that?
So I put in my snow leopard dvd to boot into that, but I can't even get it to boot into the install dvd.
Did the previous owner also give you the discs that originally came with the computer? Those are what you need to troubleshoot with. You also need disc 1 to run the Apple Hardware Test.

Apple Store and AASP diagnostic testings are free. Suggest that you take full advantage of it. This way you can find out exactly what is wrong with your computer. Post back here with the diagnosis and someone will post DIY repair sites.

MacBook Pro won't boot after ram upgrade...

Hey everybody! Hope everyone is having a great Christmas! I got a 16gb ram upgrade for my 2012 MacBook Pro 15 today and I am having some trouble with the upgrade. Its an odd problem. I installed the two 8gb sticks no problem, but when I try and boot into OS X the machine shows the apple logo with the spinning wheel underneath, and then it just shuts itself off. I don't know what the problem is. The machine boots fine into my Windows 7 partition, and registers both sticks of ram. OS X restore also boots no problem and lets me reinstall OS X, which is what I am doing currently. IDK if this is just because of a hardare change or what. The ram I installed is Adata pc3 12800 1600mhz ram, so it should be supported.

Replace the Ram, buy from OWC or Crucial, buy the Ram Apple recommend, don't rely on "it should work"

Macbook Pro won't boot after TM restore

Hi.
My MacBook Pro was running snow leopard with all the latest updates, when the hard drive crashed. I booted from the dvd that came with the macbook, osx 10.5.4, restored the latest Time Machine backup. Everything seemed fine until I try to reboot. I get the grey screen and the message:"You need to press the powerbutton for several seconds". I've reset the pram, powermanager and ran a hardware check that turned out ok. Does anyone have any clues as to what's wrong?
Any help would be greatly appreciated,
Regards, Espen Noreger

Yes. You need to use your +Snow Leopard+ Install disc, not the Leopard one.

MacBook Pro won't boot after update to 10.10.1

I have just updated to 10.10.1 and my MacBook Pro refuses to come back to life.
All I get is a white screen and no sign of activity.
Any clue?

MacBook Pro won't boot from HD or Install CD

I have a 15" MacBook Pro running Lion. It won't boot from the HD or Install CD.
1. When I try to boot it from the HD, it makes the boot sound and displays the Apple logo. The small "working" wheel spins for about 20 seconds, and then gets stuck mid-spin.
2. When I try to boot from the Install CD, I eventually get a gray screen with a large power button image and the text "You need to restart your computer. Hold down the power button for several seconds or press the restart button."
I have tried resetting the PRAM and SMC per another post, but nothing changed. I have also tried to boot it from an Ubuntu 11.10 CD, which also got stuck.
Any idea what the problem could be and next steps I should take?

My Mac started freezing (colored pinwheel) every time I tried using any application (i.e. Safari, iPhoto). After restarting for the 2nd time, it would no longer boot - makes start up sound but gets stuck on gray screen w/ apple icon. I tried resetting PRAM also - did nothing. I decided to reinstall OS; problem now is my HD is nowhere to be found! I am a tech dummy so this is way beyond my comprehension...I'm not seeing my HD from the Disk Utility either???
Side question...I backed up my files (mostly pics JPEG and videos) on DVD (had to compress to save). Why can't I open files on PC?

Macbook pro won't restart after time machine install on new hard drive

I installed a new 500 GB HD on my 13-inch mid 2010 Macbook Pro (since the original crashed). I successfully connected to the Disk Utility via the internet connection and started recovery from a recent Time Machine backup....but, the computer will not restart. It's been stuck in the grey screen with the Apple logo and rotating status bar all night. I shut it down and restarted, but it won't go past the grey screen state. I can't find any answers on the Support Page. Help. Any one else have this issue? Should I have first installed the Lion OS X first and then restored from the Time Machine backup?
Also, wondering if all my programs (2011 ILife & IWork and Microsoft Office) will be reinstalled with the back up? (I can't find my installation disks for ILife and IWork :-()

Time machine is easy to set up and theoreticaly recover from. There have been reports of problems when a different disk or computer is used.

For future reference you may wish to learn about and use cloning of the HDD. I use both CCC and SD to do this and consider it to be the most reliable way to back up and recover.
