Macbook Pro, Random Freeze on Shutdown/Restarts

I need help diagnosing an intermittent MBP freezing issue. When I go to shutdown or restart my laptop, it will occasional freeze, and I have to force power off using the power button. This is a total pain, because I use my laptop primarily in clamshell mode, and it's kept tucked away, so accessing the power button is non-trivial.
I really have no idea where to begin diagnosing this problem.

I am facing the same problem. Look at this thread and lets start ruling out by deduction: http://discussions.apple.com/thread.jspa?threadID=2513205&tstart=0

My MacBook Pro is freezing and then restarts. Kernal Log showing I/O errors

My MacBook Pro is freezing up and then restarts. It started happening about 2 weeks ago. After several attempts to resolve it, I did a clean install of snow leopard. And then did a SW Update. I have no thrid party devices, ram, or HD. My machine is 2 GHz Intel Core Duo. 2GB 667 MHz DDR2 SDRAM.
My Kernel log is showing a bunch of I/O errors.   I think I have a sick baby. Any thoughts

William, Thank you. I did do the reformat with the DVD SL Disk Utility with the write zeros once option.
I think the way to go is buy a new HD. They are cheap enough. In researching this, I found some discussions that there are some possible issues with using the newer SATA 3.0 GBs drive on my old intel core due macbook pro.
Here are 2 threads - https://discussions.apple.com/thread/2673222?threadID=2673222&tstart=180 and http://www.mac-forums.com/forums/apple-notebooks/206962-will-hard-drive-fit-my-m acbook.html
Do you have an opinion on that?
I found this one http://www.bestbuy.com/site/Western+Digital+-+Scorpio+Blue+250GB+Internal+Serial +ATA+Hard+Drive+for+Laptops/9024147.p?id=1218012522486&skuId=9024147&st=WDBABB25 00ANC-NRSN&cp=1&lp=1
which looks like it is compatible.
Am I better off buying a genuine apple replacement or an OEM?
Thanks

Hi There,
This issue appears to have occured for other people in different forms but there does not appear to have been a conclusive answer to the problem, so here's hoping someone here might be able to provide some further insight into the issue, and with some luck, a solution.
I have an early 2008 MacBook Pro running OS X 10.7.2 (plugged-in to power) that has started to randomly shut down and then restart itself (goes through all the start up screens; Apple logo etc.). It doesn't appear to be just a straight restart of the machine, but it shuts down, and then a couple of seconds later, reboots, as though it is two different actions...
The computer does this pretty randomly, and now quite often. It happens when applications are running, Safari for example, and when nothing is running and i just go to open Finder or use Spotlight.
I haven't had this issue in the past (some 3+ years of full time use now) and as far as i'm aware, nothing changed on the computer immediately prior to the issue occuring (no updates, installs etc.).
I've checked the systen log which, each time the issue occurs, returns the message 'Previous Shutdown Cause: -128'. I've sought reference as to what this refers to, but it would appear to be a mystery to the WWW.
I have tried the following solutions with no success:
- Proper restart and reboot of system;
- Repair permissions;
- Reset SMC;
- Reinstall OS X.
Any thoughts on what the problem is, what the '-128' refers to, or what more i can try to solve the issue?
Your help is much appreciated! Thanks.

I know this is a really old thread, and everyone's probably already bought new computers now. However, I'm still using my 2010 MacBook Pro and have been experiencing this very frustrating issue. However, I think I just found a way to open a finder window that prevents the shut down. In Finder>Preferences>General, under "New Finder windows show", I had "All my files" selected (BAD?), which probably was the cause, because setting that to "Desktop" instead has prevented shut downs, for now. Just thought I should share this tip, in case anyone else suffers from this annoying issue. If anyone has a better tip or a real fix, please post a reply! There are still people, like myself, working on these older machines who would appreciate the info. THANKS!

MacBook Pro Random Freeze

I have a 15" 2.66 GHz Intel Core 2 Duo MacBook Pro with 4 GB RAM and a 320 GB HD.
My MacBook Pro was working fine until several months ago it started freezing randomly. It would freeze during normal use of the computer and would be completely unresponsive for a couple seconds to a couple minutes. Sometimes, I had to force restart. The frequency of the freezes increased, and one day, it just wouldn't boot to OS X. It was really strange, since I had Windows on the laptop using Bootcamp, and that would work. When I tried to restore using my Time Machine, it froze after an hour. I tried it a couple times using different versions and all versions froze. I had to a fresh install, and migrated my data using Migration Assistant. For a couple weeks, the computer ran fine. However, one random day, the original problem started up again. The frequency increased, and this time I took it to the Apple Store. They created a new user account, and it didn't seem to have the problem. I moved all my files from the old user to the new (copy & pasting). The problem disappeared, but reappeared like usual after a few weeks. I took it back to the Apple Store again, and they changed the hard drive. After I had moved my files over, I noticed the computer freezes randomly.
I thought maybe my iTunes Library or iPhoto Library were corrupted, so I moved them to the Desktop. iTunes and iPhoto created new folders in the respective Music and Pictures folder but the problem persisted. I have no idea what's causing the problem, and its EXTREMELY frustrating. Its very difficult to work on this computer.
I tried all the major debugging methods: repairing file permissions, repairing file permissions on the home folder, fsck, etc. Everything seems to be in proper order.
Any help is greatly appreciated.

I am facing the same problem. Look at this thread and lets start ruling out by deduction: http://discussions.apple.com/thread.jspa?threadID=2513205&tstart=0

Mid 2009 13.3" Macbook Pro random freezing issue

Hi all,
I had a 2009 13.3" Unibody Macbook and last week purchased a 13.3" Macbook Pro. I had installed 4GB of RAM in the MB myself, and it had worked fine for the month I owned it.
I backed up my MB with an external USB hard drive using Time machine, restored from this backup on my MBP and moved the 4GB RAM over.
When using the MBP I get random freezes lasting between 1 and 3 seconds, occuring every 5 to 30 minutes.
Could someone please advise a good way to diagnose this problem further? I am guessing it is not the RAM as it worked fine whilst in the MB.

I have an update!
I made an appointment with a local Apple Genius Bar and talked to a technian. He said it was neither the RAM nor the Hard Drive at fault.
His only thoughts were that a software issue was the root cause. I have been doing some serious investigating this morning and figured it out. Viewing system.log in Console shows:
SMS::infiniteIntTimerEventHandler ERROR: we have infinite interrupts, disabling
At exactly 5 minute intervals. These correlate with the freezes (to the second).
SMS refers to the Apple Sudden Motion Sensor. I disabled this by doing "sudo pmset -a sms 0" in Terminal, rebooted and everything is fine.
I have no idea why the SMS thinks the Macbook is falling every 5 minutes, but when it occures the hard drive heads are locked down to prevent damage, which is a perfect reason as to why iTunes would crash but Spotify (streaming internet music) does not.
Problem solved!
Edit:
In reply to some questions posted by other members (thank you by the way).
I did install EFI 1.7 update. I did not use the Migration assistance. At some point I will do a fresh install then pick and choose parts from a backup rather than using a full Time Machine Restore. This could still have been the root cause of the issue, but it is hard to tell.
Thanks guys!

Mid 2010 15" Macbook Pro Random Shut down and Restart

I know this questions have more than likely come up a few times. But I have a mid 2010 15" Macbook pro that, for the last year, has randomly shut-down and restated displaying an error message each time. I have had this computer into three different computer repair shops over the last few months, two of which were apple certified, and have had a range of reasons provided for the issue. Anything from Motherboard to hard drive to virus. I have replaced the hard drive, did a complete reformat three times, and downgraded my OSX. But I still have the same issue. I recently came across some support tickets referring to an issue with this model of Mac, something to do with the graphics card. I downloaded a program that was supposed to be a work around, but am still having shutdown issues. I also heard that apple did a free replacement of the motherboard on these machines within 3 yeas of purchase. Obviously I am past that point, but I was hoping that there would be some other suggestions. I have ran an etrecheck on my machine and have attached it below. Can anyone provided any ideas of how I can fix this without having to buy a new motherboard?
Thanks for the help...
Cheers,

Macbook Pro random freezing

Hi, I am experiencing random freezing of OSX, First I thought it was related to the latest flash, so I deleted it but the freezing keeps happening. Then I thought it was firefox so I switched to safari 5 but still it freezes.
Now the computer freezes randomly, some times while on the internet, some times while using mail.app, some times just sitting in the finder.
It freezes also every time I try to sync photos to my 3GS in itunes.
It also freezes after Steam is open for a while.
It is a unibody Macbook Pro, 17 inch, early 2009, 2.8 GHz Intel core 2 Duo, 4 GB 1067 MHz DDR3.OSX 10.6.4
If anyone has any ideas how to solve this it'll be much appreciated.

I upgraded my MBP 2009 Unibody from the original 250GB HD to a 500GB 7200rpm HD, only to experience the dreaded freezing. Freezes randomly and shows the Beachball for about 30-60 seconds. So, I put my old drive in for a while. Then later, (about3 months), I got another 500GB 7200rpm drive. Installed it, and same problem. So I put it back like it was after having to delete a bunch of stuff to get it below 250GB so I could continue to use it. Later got a 3rd 500GB 7200RPM Drive and SAME PROBLEM! So, I put a 320GB 7200RPM drive and it ALSO has the same problem.
However, each time I did this, I used Disk Utility to copy the data using the Restore command to the new drive. While connected via USB, the drives all worked great. Put them INSIDE the MBP and they give this problem randomly.
I'm really getting sick of it.
Then on August 19, a "fix" was released as a firmware update. I just found this tonight and when I ran it, I was told "This computer does not need this update." So, I guess it's only for APPLE BRANDED Drives, not my other drives. I've tried Fujitsu, Western Digital, and Hitachi drives and they all give the same problems.
Anyone know what I can do to fix this?

Macbook Pro randomly freezes time to time

My Macbook Pro, end '11, randomly freezes from time to time. Especially when I'm on iTunes/Spotify/VLC/Skype. I ran the Etrecheck program and got this output. Could someone tell me how to fix this? It isn't exactly really ****** but it does get frustrating to have to wait 5-30 seconds.

Nurul N,
you can find out what resetting the SMC would do by following the link and reading what’s there.
Which tech guy did that? Did it come from the factory with 8 GB of RAM installed, or was it upgraded to have 8 GB of RAM after you purchased it? If the latter was the case, then the possibility exists that the freezing up is due to a fault in the currently installed RAM.

MacBook Pro randomly freezes

I just bought the new 13" MacBook Pro less than a month ago, and randomly it will freeze. By freeze, I mean nothing will respond. The trackpad, keyboard, display, music, mouse will ALL lock and the only thing to do is shut down using the power button. There is never a warning when it will happen, as it has happened when several applications were running, as well as none. I do not know what to do. Apple support suggests an erase and install.
Help?

If this were just a normal repair job, I'd suggest just sending it in for repair would be fair. However, knowing how sinister this problem is, I suggest firmly but politely requesting a replacement. Some people have blamed this problem on the RAM. RAM can indeed cause this kind of problem. But there are just too many people having this problem (even with RAM that shipped with their machine straight from Apple) that the problem seems to lie elsewhere. In a laptop, there isn't much inside the case except for the logicboard. Well people have reported on these forums that they have had their logicboard replaced only to have the problem happen again. This would suggest that another piece of hardware (though not much is left except the display, optical drive, and RAM) or even software issue could be the problem. Well everybody who calls in about this issue to Apple gets the "Archive and Install" speech, which we do, only to have the problem remain.
You shouldn't have to deal with any repair this soon into your purchase. Mistakes happen. If a key fell off the keyboard, you'd deserve a repair, not a replacement. You have already pretty much ruled out a corrupt OS install of being the problem. So it's either faulty hardware or a really obscure bug in software that has yet to be fixed.
I'd still suggest asking for a replacement. This is against their policy, so what I would do is phone up Customer Relations first, explain the situation and see if they'll authorize a replacement. Then head to the store with your case number. If they won't authorize a replacement, and you're fine with trying a repair, tell them that if the repair does not fix the matter that you would like a replacement as the next step because the problem fundamentally makes your computer unreliable. I have had it freeze during presentations. I have had it freeze and corrupt data. This is totally unacceptable of any computing product today let alone one made by Apple.
Good luck.

My MacBook Pro randomly freezing ever since new logic board?

My mid 2012 MacBook Pro 13" keeps ok randomly freezing ever since I've had a new logic board fitted after my macbook needed a new one (it was fixed through stormfront which is an official apple retailer). It will just freeze, won't be able to move the mouse or anything, and sometimes when I turn it off by holding down the power button, I can most of the time hear a click, but not everytime. Sometimes it freezes when starting up, sometimes it lasts a while before freezing, but recently it's been more like every 5-10 minutes. Can anyone help me as to why this is happening and what the problem may be? I'm running OS X Mavericks. Thankyou.

Why is my macbook pro randomly shutting down and restarting?

My macbook pro is randomly shutting down and restarting. It started a couple days ago and seems to happen completely randomly. I did a extended hardware test and no problems were found. I reset the SMC and that didn’t work. Battery is charged and I don’t think its overheating. Im using Mavericks 10.9.1. Someone please help because I can’t even use my mac for anything lately and its really annoying.

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful.

Brand new 2011 MacBook Pro Randomly freezing

Hi,
Im a bit concerned I have just got a BRAND NEW MacBook Pro 2011 and already I have had 4-5 random freezes where i have had to hold down the power button to bring it back to life!!
These have happend as i said just randomly, for example i lifted the lid to wake it from sleep mode and it just frooze on me, became totally unresponsive??
Another example was when i went to paste a url using cmd-v and it frooze on me??
I'm a bit dissapointed as I have just switched from windows PC's because I had had enough of that sort of thing and believed these where solid machines with very little issues comapred to a windows system!! and for 2k I don't exect it to freeze especially within a week!!
I'm hoping its down to software issues to which a software or OSx update will solve.
Any Ideas?

Hello, I have had very similar problems but with the MBP not even registering that a charger is plugged in (no light coming on and no change to the battery symbol).
I had a mid 2010 model that was sent in 4 times to be fixed, with no change, followed by the unit being replaced altogether with the latest 2011 model, only to find the issue persists (the charger was replaced early on as well).
The only retaining factor is the Lion software which forums have highlighted has effected charging when individuals have upgraded.
It is appalling that a company like Apple have not taken steps to address these issues and will go as far as to replace all components TWICE in one Laptop, as well as give out a new Laptop, without tackling the real problem.
Appalled and ultimately very disappointed.

MacBook Pro randomly shuts off and restarts a few seconds later

I brought my computer to the Apple store a couple months ago because the USB port was broken and my computer would randomly shut off. Long story short, they fixed the USB port, deleted all my files, and reinstalled Leopard. The random shut off problem still persists. I have a feeling it has something to do with the graphics card as it seems to happen more frequently when I'm using graphics intensive applications (photoshop, illustrator, autocad through vmware fusion, watching videos on a second screen, etc).
Has anyone had a similar problem? Should I just bring it to the Genius Bar again?

I know this is a really old thread, and everyone's probably already bought new computers now. However, I'm still using my 2010 MacBook Pro and have been experiencing this very frustrating issue. However, I think I just found a way to open a finder window that prevents the shut down. In Finder>Preferences>General, under "New Finder windows show", I had "All my files" selected (BAD?), which probably was the cause, because setting that to "Desktop" instead has prevented shut downs, for now. Just thought I should share this tip, in case anyone else suffers from this annoying issue. If anyone has a better tip or a real fix, please post a reply! There are still people, like myself, working on these older machines who would appreciate the info. THANKS!

Macbook Pro 2011 - Freeze/Ask for Restart

I just purchased the new Macbook Pro 15 inch from the apple store. Seriously a beast compared to my Late 2006 Macbook. Surprised at how much of a difference it truly makes. I sold my old Macbook to help pay for the MBP and haven't looked back. Now i'll stop gushing.
The one and only issue i have with the Macbook Pro is that twice it has frozen, and greyed out the desktop and popped a message up asking me to RESTART the MBP in about 3-4 different languages. I was wondering why I might be having this issue? I mean this is about a week old and this message is cropping up. Just wondering if anyone has encountered this and their solution.
My only solution which i haven't tried yet would be a boot from CD and disk utility repair of the HD, but is that necessary?

Ho Lee,
Thank you for your quick response, I came across that as well when I was searching for answers as well. I'm not new to troubleshooting macs but just was wondering if anyone else was encountering the issue as well.
But that was a good reminder to dig deeper into which programs are active when the Kernal panic occurs and make sure they are updated to the newest realease.

Macbook Pro retina freezes and then restarts

I have a 15 inch Macbook Pro Retina (Mid 2012) and it was working fine till I installed Yosemite. I would like to know is there any way to solve this problem? It is hard to work on computer which restarts about 2 times a day.

Hi EditorBob,
That doesn't sound good. Have you run the Hardware Test (Using instructions described here - http://docs.info.apple.com/article.html?artnum=303605 ) ?
The problem may be related to bad RAM, but if the hardware test doesn't find anything, you should probably take it into an Apple service center or store.
