MBP freezes at startup after several crashes

I have an older MBP, I think it's a 2008 running Snow Leopard. I am backed up. Computer screen started glitching while watching videos online and would freeze (screen would glitch strangely, I could move the mouse but nothing on the screen was responsive). I'd have to manually power down and at first it would restart if I'd insert the installation disk and boot into startup manager and select hard drive. But after a few more crashes it will not boot at all. I've removed the hard drive and used another MBP to repair disk, hard drive appears to be fine but the computer still wont boot. I don't believe it is a hard drive problem. In fact I'm having the same startup issues with 2 hard drives (both with the same version of snow leopard) installed internally. What happens at startup is the apple logo appears, spinning wheel appears but it stops spinning and it doesn't seem to go any further. This happens when I try to boot from install disk or boot into startup manager or into disk utility and even when trying to startup in Apple Hardware Test. Spinning wheel stops then nothing.
I have tried resetting nvpram. I have been able to boot into verbose mode but it appears to freeze up again after a short amount of time. I tried booting into safe mode and the progress bar showed quickly then spinning wheel stops again. My original plan was to do a fresh install of the OS and do a time machine backup but the comp won't start in any mode.
Does anybody have any ideas what I could do to fix this problem?

It unfortunately sounds like it could be what's called an "intermittent generic fault." I use a product called Scannerz (http://scsc-online.com/Scannerz.html) and in some of their documentation they describe this type of fault. Scannerz can actually test and detect this type of problem if it's in the development process, but the system needs to at least be bootable, and it doesn't sound like your's is. I think it's described in their downloadable document about hard drive testing.
An "intermittent generic fault" is essentially a crack or separation in a logic board trace or connection, or intermittent connection in a cable, or even the connection itself. If it's in the logic board, such as in a cracked trace or a marginal solder connection that went bad, it may get worse with more CPU activity because it causes the heat in the unit to go up, cracks in traces or solder joints expand, and a disconnect occurs. This might explain your video glitch. According to them, if this is the problem, it typically gets worse over time until the system becomes unusable. If it's in an I/O cable it can be easily fixed by replacing the I/O cable, but if it's in the logic board, it basically means you need a new logic board. Intermittent connections with something plugged into the logic board may also cause this type of erratic behavior. Sometimes just re-seating connectors can do the job. I've personally seen this type of problem happen when Airport cards on the old PPC based Aluminum PowerBooks worked their way loose - reseat them and the problem goes away.
Another thing you could also try is the PM reset. It might work because I've seen it mess up booting, but that wouldn't explain the erratic lock-ups you got with the video. Some of the MacBook Pro's have a diagnostics connector connected to them and Apple can apparently connect diagnostic equipment to the unit to diagnose a whole host of problems, but I don't know if your system has this feature because it's relatively new.
I hope this helps you in some way, and good luck.

Freeze during startup after SW update from 10.4 - 10.4.8

After updating to 10.4.8, my machine would freeze during startup (at the gray screen with the apple and spinner) and give me the "Please restart your computer" message in a few languages.
I thought it might be a RAM issue, so I removed all third party RAM - same problem.
I replaced all of the RAM with RAM from another G5 that I know worked - same problem
I moved the HD from my G5 to another G5 that was working - same problem (I believe that eliminates the motherboard and any other components from being the problem).
I thought that the HD might be bad, so I replaced it with a brand new SATA drive, installed 10.4 and it worked perfectly, ran all of the SW updates (including the combined 10.4.8 update) and I get the same freezing again when I reboot.
Any suggestions are appriciated!

Hi Joe,
Welcome to the only place where you can get friendly advice.
Ok have you tried starting up from the installer / restore CD that came with the mac and run disk utility??
Try hardware test doing the extended test in a loop to try and find the base of the Kernel panic (thats what the "you need to restart your computer" image indicates)
For info and guidance on Kernel panics see:

Worst case senario it could be the G5 processors, make sure you have applecare; just in case it gets expensive!!

Macbook air 2013 freezing at startup after yosemite update

My 2013 Mb air has started freezing at startup. performing a safe reboot seemed to help, but once I restarted immediately after rebooting it froze again. A second try apears to have done the trick, however, now my volume is completely off and non-responsive, and Safari is not really working. This is one day after updating to Yosemite.

same for my MBA 2013 model...its taking very long to show me the password box after clicking the username.....it happens everytime i restart...once it starts, everything is fine...if i had to force restart it (it froze couple of times), it takes really long to reboot...and again login is a big deal...any ideas/tips ???

2010 15" MBP Freezing at startup

About an hour and a half ago when I activated it from sleep, the screen flickered and logged me off. I logged in and the same thing happened again.
I used Disk Utility to verify the disk and DU said the hard disk needs to be repaired.
So, I put my OSX disk in and had to restart in order to use disk utility on it.
However, when I restarted, my MBP wouldn't get past the startup screen.
After looking the issue up online, I tried booting into safe mode and booting straight off the DVD, to no avail.
Finally, I tried booting in single-user mode, and it doesn't get past
"Loading System\Library\Caches\com.apple.kext.caches\Startup\Extensions.mkext......"
Any help?

I don't know whether your data can be saved. If you have another Mac with a Firewire port, you may be able to copy data off the internal drive by starting up in Firewire target mode. Otherwise, remove the drive and install it in an external enclosure or dock. They may be willing to do that for you at the Apple Store; I'm not sure. The first order of business when you get it back should be to set up a regular backup solution for all your data.

HT4527 How to transfer iPhone content (playlists, notes, calendar, contacts) to a MBP's iTunes library after a crash where I had to reinstall everything?

I have a MBP and the hard drive crashed. I had to reinstall everything from zero. I didn't have a back-up of everything. Now my iTunes library does not recognize my iPhone and ask me to erase it to sync it. How can I transfer content from my iPhone to my MPB and rebuild iTunes library from my iPhone?

I have discovered the solution and it involves an issue I suspected. After the restore of my old Time Machine Lion files to my new MBP running ML, the restore restored my computer back to Lion. After an install of ML, my computer worked perfectly except the fancy Scroll and zoom featured we all love from the trackpad. Ha already installed ML on other partitions and the trackpad worked perfectly on them. Even the guest login's trackpad worked perfectly but not the main admin account.
First thought was to create a new admin account and copy everything from the old admin to the new admin and then delete the old admin account. Hated the idea because all files had to be copied rather than moved.
So what was left to do. I had thought of deleting all the apple preferences from the library and replace them with the contents of the library on another partition in ML. First I deleted old preferences many of which were old Lion preferences. That didn't solve the issue.
I forgot that Lion and ML HIDE the user library so I was working on the wrong library. Discovered the Terminal command "chflags nohidden ~/Library" and I chose to reveal the user library on a ML partition.
Solution:
I booted into another ML partition. I guess that I could have booted into the new admin user account and changed the permissions to access the old admin users Library But I chose to boot
from another ML partition: copy ALL the com.apple. XXXXX.plist files and the folder BY Host. It has special hidden files. Other way is to copy the Preferences folder we'll say into the Desktop.
I then proceeded to delete ALL the com.apple…….plist files and the Host folder into the trash. Then I copied all the apple.com…plist files and the Host folder and then rebooted. And now my wonderful Trackpad works as mountain Lion intended it to work.
I'm leaving this solution because there's someone else in the MacWorld with the same issue.

Freeze at startup after System and Firmware update - Help!

I took the automated system upgrade last Sunday including updates on a bunch of Apple applications, OS X 10.4.6 (it was included if I recall correctly) and a SMC Firmware update. After downloading all files and installing them my iMac restarted. After that the SMC Firmware upgrade started and I followed the instructions ending in another restart.
This is where my problems began. At this startup I got through the grey screen with the Apple logo and got so far as to the blue screen with the Mac symbol saying something like "starting up". The progress bar started moving and froze after reaching about a fifth of its final length.
As this was a firmware update I didn't want to interrupt anything so I left it for the night (no progress in the morning) and for the next day. Still no progress when I came home from work so I shut it down (pulled the power cord).
Efter this I've tried to fall back using the Firmware Restoration CD available at Apple's support page, but this doesn't work. My iMac refuses to start the installation of the old Firmware even though I follow the fallback instructions. (After starting the computer and keeping the power on button pressed I wait for the front light below the screen to first flash rapidly for a while and then do a SOS (three short, three long and three short blinks). The SOS however, never happens, instead the computer proceeds directly to the grey startup screen before it freezes when it reaches the blue screen.
I have no clue to what to do. Any and all help will be greatly appreciated.

minxlj,
It is not my intention to be rude, however, it is my intention to be direct. Do you have a G5 or do you have an Intel Core Duo, or perhaps even both? Because right now your signature says you have a G5, which has PPC chips in it made by IBM, not Core Duo chips made by Intel.
The reason I ask is because, just as in another Discussion here in the Intel forum, you are responding to information that appears to not apply to the computer you say you have and you are giving information that, if you have a G5, does not apply to the computers of the folks here in the Intel forum.
Could you please clear that up by correcting your signature so everyone here knows you are comparing oranges with oranges and not mangos with oranges?
Staffan,
As far as the SMC Firmware update and the Firmware Restoration CD, the two items are not related. The Firmware Restoration CD is only for the Firmware Update that came out in mid-April. It is intended for someone whose computer messed up in the application of the Firmware Update and is intended to bring their computer back to its Firmware state prior to the botched Firmware Update. It will not assist you if you had problems applying the SMC Firmware Update from early May.
If I am understanding your description of your Mac's problem it sounds if if you have successfully installed the SMC firmware update, but now have a possible 3rd party satrtupitem that is not allowing your Mac's OS X to fully boot. You can check to see if both the Firmware Update and SMC Firmware Update have been successfully installed by booting your Mac into safe Mode by pressing the "Shift" key during startup. This boot will take longer than normal because it is verifying and repairing your directory. After the desktop appears, go to Apps/Utilities/System Profiler. In the Contents section, highlight Hardware and Hardware Overview should show; Boot ROM Version: IM41.0055.B03 for the Firmware update and SMC Version: 1.1f5 for the SMC Firmware Update.

Muse freezes on startup after last update...

I did the latest update (as of April 19th 2012) and now when I try to open it freezes at the splash screen. I am not sure of a work around - I am pretty much locked out. Anyone else have this issue or any thoughts on how to resolve it?
Syste: iMac 2010 - OSX Lion

Problem solved - at least for time being. Sorry to bother others but maybe somebody else had similar problems.
So, after reinstalling Firefox several times unsuccessfully I checked the computer with Malwarebytes. And surprise, surprise, there was seven warnings about "PUP:Software.Updater". I removed them with Malwarebytes and after rebooting tried both Firefox and I Explorer and they started up nicely.
So, it was malware although I was not willing to believe it. Surprising coincidence (?) was that I discovered it after updating operating system with security fixes, Java and Flash. Has it been already on my disk waiting for that or what ? Gurus, tell me if you can !
Finally I also found similar case here which also convinced me to try that approach also if I hadn't been there yet. So, if I had been more patient going through these notes etc I wouldn't have bothered others. Sorry about that.

System 10.3.9 freezes at startup after installing Security Update 2006-007

I installed the security update 2006-007 this morning and upon restart everything froze once the words "login window starting" appeared.
I tried a bunch of troubleshooting suggestions from the support pages ("Your Mac won't startup in OS X - 10.3.9 or earlier") including starting in safe mode, single user mode and dumping login preferences, network prefs, reset certain priveleges. None of these solved the problem.
Is the only work around for this to re-install the system?
PowerMac g4 dual proc. Mac OS X (10.3.9)

Ed,
I admit to being somewhat perplexed by your experience. But let me ramble a bit here anyway.
My opinion is that problems of the sort that you are experiencing (freeze after a software update) are almost always due to some software problem. (I base this opinion to a large extent on the experiences of other people in these forums.) The fact that your system works okay with Tiger is consistent with this idea.
But, if it is a software problem, why did it not go way when you re-installed Panther? I am wondering how you did the re-install. Was it an Archive and Install? That is the easiest approach and the first one to try, but there are some things it cannot fix. For one, if user settings and preferences are maintained during the A&I and the problem is related to these settings or preferences, then the problem will remain. In that case, an Erase and Install would be needed to clear out everything. Of course, this also deletes all of your data, so it is something you do not want to do unless you have a backup (which you said that you have).
Another thing that an A&I cannot solve is corruption of the filesystem (computer loses track of where some files start and stop on the hard drive). This problem can usually be detected and often repaired by booting off your install CD and using Disk Utility to repair the disk. You said that you used Disk Utility but gave no other details. I take that to imply that you detected no problems. If there are problems and Disk Utility is unable to fix them, a more powerful utility can sometimes do the job, and sometimes there is no solution except to reformat the hard drive and re-install the operating system. This of course destroys all data on the drive.
If there were a hardware problem behind this, the most likely thing in my view would be some bad blocks on the hard drive. I am pretty sure that Disk Utility, as used above, will look for bad blocks and mask them out if any are found. You mentioned something about 1 Gig of RAM. I think that RAM is unlikely to be the culprit. Problems with RAM usually are manifested as more erratic behavior that what you are experiencing.
You have already exhausted many of usual tricks, so what are your options? It sounds like you do not want to buy a copy of Tiger just to fix this and I can understand that. So, you could go to more and more extreme versions of re-installing your software. By this I mean using your Panther install disks to do an Archive and Install, then to do an Erase and Install if the first did not work, then to reformat and do an install if the Erase and Install did not work. Before doing either of these last two step,s you want to be sure that you have backup that you know works. You have said that "re-installing Panther does not fix the problem" and also that you "haven't done a system restore". It is not really clear to me what you mean by re-installing Panther. Was this from a backup or from your install CD?
If you want to avoid a re-install from your install CD as long as possible, then my suggestion is to attempt to troubleshoot the problem further by booting into Single User mode (which I think you have done). Once you get the disk mounted, I would suggest looking in the system.log file for an error message. Once you have mounted the disk, you can look at the end of the system.log file with the command
tail /var/log/system.log
Look to see if any of the messages look like they might be indicative of a problem. If you see nothing, you can print out more lines by doing this:
tail -40 /var/log/system.log
which will cause the last 40 lines to be printed. If you see any message that might be hinting at a problem, post it back here and perhaps someone will get a clue. I should say at the outset that this way of doing things takes a lot of patience and is not guaranteed to provide a solution.
I hope this ramble helps a bit. I know your are frustrated and I hope you get a solution soon.

Freeze on startup after adding additional admin login

In addition to my original admin account, I added a root admin account (in case I ever wanted to use terminal mode). Then I added another standard user account. That worked fine but suddenly I could not log in with my original admin account. So I decided to give the standard user account admin status. Now, I can't login to anything. When I start the computer, it freezes once the "Mac OSX - Starting Mac OS" screen fills the blue progress thermometer. Of course, this is a disaster and I cannot use my PowerBook at all. I do not have a startup disk for this computer. I have tried starting in Safe Mode as well as preventing automatic login and resetting Parameter RAM with no success. Any help would be sincerely appreciated!

Hi, and a warm welcome to the forums!
Tough without the Tiger Disk problems, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: 
o The volume (nameofvolume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: *** FILE SYSTEM WAS MODIFIED ***   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

[SOLVED] Laptop freezes at startup after kernel upgrade to 3.13.6

Some days ago I got a new Dell Sputnik 3 Laptop and installed Arch Linux with UEFI Boot and gummiboot as bootloader. The installation was successful.
However two days ago there was an upgrade for the Linux Kernel from 3.13.5 to 3.13.6. When I restarted the Laptop after the upgrade of the kernel the Laptop freezed directly after pushing the power button (never got ahead of the initial DELL logo).
I ran the DELL hardware diagnostics to identify a possible damage of the SSD but everything was ok. Than I booted into a live system ad mounted the root partition and there was no problem work on it. Additionally I change the value of timeout in gummiboots loader.conf (it was commented out before). Since than I got the gummiboot boot menu at least. So narrowing down, I think something happened during the kernel upgrade. Unfortunately I have no clue what could it be since I am convinced that at the installation process some days before I did everything like it was described at the beginners guide so automatic gummiboot update had to be possible.
The drive is partitioned in the live system looks like this (look at sda):
├─sda1 8:1 0 512M 0 part /boot
└─sda2 8:2 0 235G 0 part /
fstab like this:
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/sda2
UUID=3f216fdb-f4c6-459a-856f-6f246d7a5bff / ext4 rw,relatime,data=ordered 0 1
# /dev/sda1
UUID=0F8F-2A3B /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2
# swap
/swapfile none swap defaults 0 0
I have and arch.conf in gummiboot looking like this:
title Arch Linux
linux /vmlinuz-linux
initrd /initramfs-linux.img
options root=/dev/sda2 rw
and the loader.conf of gumiboot looking like this:
timeout 5
default 56cccedc29f1418ab2d8f1762ea09471-*
Now, I don't know anymore how to proceed to identify the problem and hopefully solve it

looks like this issue might be the same:
https://bbs.archlinux.org/viewtopic.php?id=172961&p=1
If I find time I might try using an alternative to gummiboot to see if this works.
Update: There also seems to be a reopened bug report on this https://bugs.archlinux.org/task/33745

New iMac freezing on startup after NTFS install

I have a new iMac with OS 10.7.4 that freezes for 5 minutes upon startup, then starts working normally. During this time there is no response to the keyboard or the mouse. Force Quit has no effect. I have it set to start without a password so it goes straight to the desktop. This behavior started when I installed a Paragon NTFS interpreter from my Seagate external hard drive. This is done during the setup install from the hard drive to allow both Mac and Windows to use the drive. I have tried this three times, reinstalling the OS each time to get the Mac working again. The drive came with a USB 3 base which is bad news for an iMac. Seagate sent me a firewire base and I hoped that would solve the problem, but no luck. The NTFS interpreter has been uninstalled and the Seagate external drive reformatted as a Mac drive. Everything now works, but the freezing behavior still persists, and I suspect that some startup files for the Mac are corrupted by the NTFS software. I ran the bootlog in the Console for one of the startups with freezing. The following is the only thing I see that seems unusual:

Here are the specs for your HP Pavilion p6720f Desktop Computer. According to the specs your system came with integrated graphics using ATI HD Radeon 4200 and a 250 watt power supply. You indicate that your computer now has an ATI Radeon™ HD 5670 Graphics card installed and you are having issues. According to AMD the reference ATI HD 5670 graphics card requires a minimum of a 400 watt power supply. If this is a retail card, you will need to upgrade your power supply to accomodate this graphics card. The Corsair CX500 and CX600 power supplies are good choices and are known to fit many HP cases.
Please provide the make (not AMD or ATI, but Asus, EVGA, etc.) and full model number (not 5670, but HD-567X-ZNF3, etc.) of the graphics card in question for more assistance.

Firefox4 freezes on startup after about 10 seconds. A second parallel instance of firefox works normally as long as the first instance is left alone frozen. What causes this and how can it be prevented?

I am running firefox4 on win XP. When I start firefox, it says it is trying to restore a previous session which has only the blank tab. After about 10 seconds the whole instance of firefox freezes - none of the buttons work and the only way to close firefox is to use the Ctrl+Alt+Del and task manager. If I open a second parallel sessionof firefox, it works normally, as long as the first session is left alone (frozen). What could be causing the freeze up of the first firefox instance, and how can it be prevented?

I've done some research on the SQLite database. Whenever Aperture hangs up (like during auto-stack or opening the filter hud) there are thousands of SQLite queries happening. These SQLite queries cause massive file I/O because the database is stored on the disk as 1kb pages. However, the OS is caching the database file; mine's only 12MB. I'm trying to track down some performance numbers for SQLite on osx but having trouble.
It's starting to look like most of the speed problems are in the libraries that Aperture uses instead of the actual Aperture code. Of course, that doesn't completely let the developers off the hook since they choose to use them in the first place.
Oh, and if anyone is curious, the database is completely open to queries using the command line sqlite3 tool. Here's the language reference http://www.sqlite.org/lang.html
Hmm, just found this. Looks like someone else has been playing around in the db http://www.majid.info/mylos/stories/2005/12/01/apertureInternals.html

Windows 7, 32 bit freezes at startup after installation with bootcamp

Hey.
I really hope anyone can help. I have just recieved my new Macbook Pro and I would like to install windows 7 on it. Using the guide to Bootcamp everything went well and I got in to windows. But after installation of the needed drivers from the Leopard CD I needed to restart and now I cant do anything (it freezes after typing my password or sometimes even before) - I have to shut it down.
Everything is fully updated (Mac OS X 10.6.3).
I have tried to remove Windows again and installed it once again, this time i got into Windows, but I then had the same error after updating windows - even without using the Leopard update files.
Anyone know what to do?

have one more question for you...
In another environment, where everything went fine, i see green diagnostic report.
while starting admin server it gives me
\Java\jre6\lib\ext\QTJava.zip was unexpected at this time.
C:\Oracle\Middleware\user_projects\domains\EPMSystem>so still it is not installed completely!!

Mbp freezing at startup, please help!

Hey, a couple days ago i shut down my mbp and turned it on the next day. It came on, made its noise, went to the grey apple start up screen, little gear was spinning and then nothing. It stayed on this screen for a full 30 min. I haven't downloaded any new software or anything. I just got it to boot up in safe mode but, I don't know what to do with it otherwise, please help!

Try this
Boot holding down Apple/S and don't let go until you see scrolling text.
When that stops and you see a root#: prompt enter
fsck -fy
Let it run through all the checks and repairs.
If it fails first time, at any time, or finds and fixes a fault - run the command again and keep doing so (some fixes can take several passes) until it says "Appears to be OK" then enter
reboot

Make a "Genius" appointment at an Apple Store to have the machine tested. Back up all data before you go.
