Macbook shuts off during time machine backup

Hi all,
I've recently been having problems with my MacBook randomly shutting itself down - usually when I'm importing a CD into iTunes, watching GoPro files on QuickTime, for example. When this happens the fan is usually working so I'm guessing that's an overheating problem. A few other niggles have also appeared, all seemingly after I upgraded to Snow Leopard, which has made me decide to downgrade again (I think maybe its too advanced for my old machine!). So my real problem is this - I need to back up all my data and up until recently have been using an external HD with Time Machine. Now, my mac keeps shutting down when it gets to the actual backup part of the process. The fan never comes on and the mac is well ventilated and doesn't feel warm at all (ive been doing it in the morning when it's been off all night). Any suggestions as to what might be happening here, and how I can actually finish a back up? I've had a quick scout on the web for solutions (I'm not particularly IT savvy so most answers baffle me!) but have read that using 'Safe Mode' might help?
Thanks in advance,
Nina. :)

Thanks for the link to the safe mode start up info - I'll give that a go tonight.
Among other things, that will check the directory structure and fix it if possible. That might be all you need.
I'm on 10.6.8 and my brother upgraded me so I guess he still has the discs, I will check. Is that for a reinstallation?
You need the main one to reinstall OSX (only; that doesn't disturb anything else), or to restore from TM backups. You may not need to do either, but should always have the disc handy.
What did your Mac ship with, and do you have the original discs? One of them has an Apple Hardware Test specific to your Mac. It's not real extensive, but might find any hardware problems.
Only I'm not really wanting to do anything like that til I've backed up - bit of a catch 22!!
If you're sure the backups were completing until recently, eject and disconnect the drive until you need it. No sense risking any damage to them!
If you have or can borrow another external, you might be able to make a copy of the current contents of your HD on it, via the Restore tab in Disk Utility. From your description it sounds doubtful, but might be worth a try.
And/or, if you have some CDs/DVDs or a USB Thumb drive, you might be able to copy some stuff to them.

System "hiccup" during Time Machine Backups

Over the course of the past week or so, I've noiticed that my system will freeze/stall/hiccup (whatever you call it) during Time Machine backups. This will apply to YouTube/Vimeo videos, iTunes (where I noticed it... it's like the song pauses and resumes 2 or 3 times over 10 seconds), task switching, text entry, etc. Again, this is only a recent thing.
Here's a log of what I was doing during this last backup. Didn't check the time when iTunes froze, but it happened at least twice, maybe 3 times.

I restored a Macbook Pro from a Time Machine backup and now none of my passwords are working (and I know they are the correct passwords). What can I do?

I restored a Macbook Pro from a Time Machine backup and now none of my passwords are working (and I know they are the correct passwords). What can I do?

First, make sure caps lock is not on.
Another reason why the password might not be recognized is that the keyboard layout (input source) has been switched without your realizing it. You can select one of the available layouts by choosing from the flag menu in the upper right corner, if it's showing, or cycle through them by pressing the key combination command-space or command-option-space. See also this support article.
If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password. In OS X 10.10 and later, this option also works with FileVault, but only if you enabled it when you activated FileVault. It's not retroactive. Otherwise, see below.
Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions.
Start up in Recovery mode. When the OS X Utilities window appears, select
Utilities ▹ Terminal
from the menu bar at the top of the screen—not from any of the items in the OS X Utilities window.
In the window that opens, type this:
resetp
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
Select the startup volume ("Macintosh HD," unless you gave it a different name) if not already selected. You won't be able to do this if FileVault is active.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
 ▹ Restart
from the menu bar.
You should now be able to log in with the new password, but the Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as the login password), there's no way to recover it.

MacBook shuts off during startup

I have a macbook I got in 08 that is running leopard. Ok so after running Onyx it told me that the volume needed to be repaired. I inserted the install disk and ran disk utility and the volume repair, but it told me it couldn't be fixed. So I quit out of all that and restarted my laptop, but now it won't get past the blue loading screen. The little wheel just goes and goes then my MacBook shuts off. I can still run the Mac os x installer. When i go again to disk utility I can see the Macintosh hd tab and before I couldn't. Is this a good sign?
Can anybody please help? Should i just try to do a restore, if it would let me or?? This is my first time dealing with a problem with a mac and I don't even know where to start.

Thanks for responding. Yes, I have used time machine, although I stopped it from backing up data about a year ago (big mistake). I was wondering if it would be best to restore with time machine or do a restore and then connect the external hd to get my data manually. Because have I changed my login name from the last backup and I don't know if that would cause any extra problems. I really don't want to lose anymore data.
I was also wondering how to go about using diskwarrior. Is it a separate disk? Because right now I don't know how I would get the install disk to eject from the laptop.

6th Generation Airport Extreme Freezing During Time Machine Backups using LaCie 1TB Hard Drive

I recently upgraded from a 4th generation Airport Extreme (short, dual band n) to a new 6th generation Airport Extreme (tall, dual-band ac) in the hopes of having quicker backups and better WiFi performance (I also just got a 13" retina MacBook Pro).
The upgrade has gone poorly, to say the least. Initially, I set up the new Airport Extreme as I had for the old one. Then I plugged in the same hard drive I was using (a LaCie 1 TB d2 Quadra USB2 drive that I bought in June of 2009). I decided to setup my wife's Time Machine backup first (she has a 2010 MacBook Air). I removed the "old" disk (the one associated with the old base station) from her Time Machine configuration, and set up her Time Machine configuration to backup to the same disk on the new Airport Extreme. I was pleasantly surprised to find that it picked up her existing Time Machine backup and incrementally synchronized to it (the backup size was about 300 MB). A few days later, she warned me that Time Machine told her that backups were not working. When I went to look, it was indeed failing.
I tried a few things that didn't work, and I suspected that maybe the backup "transfer" hadn't gone so smoothly as it seemed, so I decided to erase the drive using Disk Utility and start the backup over again. To my disappointment, I found that the backup got about 200MB-1.5GB into the backup and "froze." I left it overnight, and it was at exactly the same place the next morning. The light on the disk connected to the Airport Extreme flashed constantly all the time, and I could hear it spinning, but nothing happened at all.
When I tried to stop the backup, it took a very long time. In the logs, I would see a message like this (this log is from my machine, not my wife's, but it looks the same):

Looking at the Airport Extreme in Finder, I saw that it got stuck, either "Connected as" me, or "Connecting...". The Airport Extreme wouldn't respond to the "Disconnect" or "Connect As..." buttons (depending on the context), and the eject button for the Airport Extreme itself in the sidebar was also unresponsive. Eventually, after 2+ minutes, I got a dialog saying "Couldn't connect to [my base station name]" with instructions to "check its IP" and contact my system administrator if the problem persists. During this time, Finder can seem frozen and unstable.
Through all of the above, the hard disk kept spinning and the light flashed constantly. The drive was warm to the touch in the morning.
I also found that when all this happened, I was unable to connect to the Airport device using Airport Utility. I I couldn't administer it, but the Internet continued to work for all connected devices. Unplugging the disk and plugging it back in worked immediately to bring the system back to a working state. I didn;t even have to power-cycle or reset the Airport Extreme.
I tried a number of things to correct this behavior:
Disabled Time Machine, removed disk, restarted machine, reconfigured Time Machine, and retried.
Tried backup on my 13" Retina MacBook Pro and my wife's MacBook Air.
I actually tried with TWO new 6th Generation Airport Extremes. The first one was a refurbished one. I returned it to Apple and purchased a brand new one. Both of them exhibited the behavior I described above.
Workaround:
Finally, I switched the drive out for a spare that I have (an older Western Digital MyBook and used it for a backup. This drive "Just worked."
So, I have switched to that for backup for now, and re-purposed the LaCie as a drive that I use for making periodic images of my hard drive using SuperDuper. The drive seems to work perfectly (and worked perfectly for several years with older Airport Extreme base stations), so I can only assume there's a bug in the USB driver of the current 6th-generation Airport Extreme.
I hope this helps someone else who's as confused as I was. If anyone has had a similar experience, I would very much like to read about it. I will be reporting this problem to apple right after I post this topic. Please do the same if you experience this issue.

As Bob says, backing-up that way isn't supported.
It's also unreliable. It may work for a while, but this forum, and the Time Machine forums, have many, many posts like this:
*"I've been backing-up via an Airport Extreme for* <some number of days, weeks, or months> *and all of a sudden my backups are corrupted beyond repair."*
In my case, it's happened about 4 times in a year. And that's with a desktop Mac, about 12 feet from the Airport, with the exact same hardware in exactly the same place and no interference.
It is very convenient, especially with laptops. If you want to take the risk, see [Using Time Machine with an Airport Extreme Air Disk|http://web.me.com/pondini/Time_Machine/Airport.html] (or use the link in *User Tips* at the top of this forum).
But do yourself a LARGE favor and take the prominent advice to keep secondary backups, and update them frequently. Sooner or later, you're probably going to need them.

Kernel Panic during Time Machine Backup

Hello everybody, two days ago I was doing a time machine backup, and I got the kernel panic message that suggested me to switch off the computer.
I did it, I restarted the computer and since then I cannot get the time machine backup to end without a kernel panic!
Side information: my HD of 250Gb has only 1gb left, OSX 10.6.6, everything updated,
I was listening itunes music during the backup.
have to be a solution!
Down here one of the latest kernel panic log:

Hi all
my Time Machine backups regularly result in kernel panics. I'm on a MBP 2.4 GHz Intel Core 2 Duo and backing up to a Time Capsule. I removed the entire backup, erased the HDD in Airport Utility, and started from scratch backing up via Ethernet. No other applications are open.
I verified and repaired the internal HDD with Disk Utility (booting from the Mac OS X Install DVD). HDD appears to be ok. Repaired disk permissions. Ran Apple Hardware Test, all ok. Removed the Preference file com.apple.TimeMachine.plist (as per #A4. suggestion). But after all this, I still get kernel panics only after about 2 or 3GB into the backup (of approx. 140GB data total).
The Time Machine widget that I installed reported this after the reboot after the last kernel panic:
+Starting standard backup+
+Attempting to mount network destination using URL: afp://Marcus%[email protected]/Finger%20Lime%20HD+
+Mounted network destination using URL: afp://Marcus%[email protected]/Finger%20Lime%20HD+
+QUICKCHECK ONLY; FILESYSTEM CLEAN+
+Disk image /Volumes/Finger Lime HD/cif-mbp-foth.sparsebundle mounted at: /Volumes/Time Machine Backups+
+Backing up to: /Volumes/Time Machine Backups/Backups.backupdb+
+Error parsing SystemMigration.log to determine source volume of system migration.+
+No pre-backup thinning needed: 146.69 GB requested (including padding), 893.87 GB available+
+Waiting for index to be ready (101)+
These are the kernel panic reports I'm getting. I took out the HEX bits ("snip"). They all report as the possible cause: "unlocking an unlocked mutex or spinlock". Can anyone suggest any solutions to this problem? Thanks heaps!

New Macbook Air transferred by Time Machine Backup USB--fan/temps

Hello,
I just got the last version of the macbook air, with 120HDD and 1.86 cpu. I thought that I would have to try to transfer everything from my Imac 27" through wifi transfer but when I started up the macbook air it asked if I had a time machine backup I would like to use through USB (which I have used many times before to basically transfer all my data, applications, and settings.) It took a while and the macbook air's fans kicked in during the transfer, which is from the Imac with snow leopard. total transfer was around 45gb. I thought this type of transfer wasn't possible. I also did a long software update after the transfer.
MY QUESTION: could any of this account for the macbook air running hot now, fan at about 6200rpm. I am in Paris and it is very hot here now, so maybe this accounts for it. I'll see in the morning. I am just wondering if the machine will run hot now because perhaps because of the type of transfer I executed, which might have included programs or apps not directly related to the macbook air itself. Again, we are in a heat wave here so perhaps this contributes to it. Don't these machines run rather quietly?
any advice would be appreciated. I could always start again, do a reinstall, etc. but except for the fans running, I have everything I need on the machine and would really prefer not buying the external dvd ir starting over again.
Thanks

I learned that the macbook air shipped with Leopard, but after migrating everything over from my Imac 27" with Snow Leopard, my system now on the Macbook Air is exactly what I have on the Imac. After the initial backup from Time Machine I did a software update, which brought the system up to 10.6.4. I suppose on some level part of one system did transfer over to the Macbook Air, or at least it updated the system that was shipped on the Air. I did call Apple and was told that if there were issues during the Time Machine backup the system would have alerted or panics would have occurred. The guy wasn't 100% sure, but felt that the backup went normally.
The Air seems to work fine, but the fans kick up from the base of 2500rpm when I watch a video or download video files for a few minutes as an experiment. I don't want to do a complete re-install with the original DVD discs, with all of the trouble that implies, if the machine is going to run rather hot with fans increasing in any case. I suppose that's why I am looking for confirmation one way or another.
It was suggested that I log out and open another account empty of data and see if that makes a difference.
If the machine will run cooler with a re-install, no problem. But it sounds as if all of that could be for naught.
Any other comments would be appreciated.

Macbook Air Freezes when Time Machine backup starts

My Macbook Air (OS 10.5.5) has started freezing up whenever a Time Machine backup begins. I get the dark shade screen telling me that it has crashed and to hard power off. Everything was working well before, including the Time Machine backups, and the only changes I have made are the Apple updates. At first I thought it was random crashes, but I soon discovered that turning off Time Machine stops the problem (though obviously does not fix it). I've tried restarting and turning Time Machine back on, but it still makes the computer crash within a minute of the start of the backup process. The backup goes to a Time Capsule. I have not seen this problem on any of my other macs on the same network including a Macbook Pro that backs up to the same Time Capsule. Does anyone have any idea what the problem could be and how to fix it?

To be honest,no I don't know why you are having this problem.
It looks like a specific problem with your MBA which could be a hardware problem (RAM most likely here) or a bad sector problem on the hard disk. If you own a copy of TechTool or something similar, run a full hardware systems check. If you don't own TechTool, run the Apple Hardware check from the MBA System install disk.
And, it could be a software problem. I don't know if this sequence will help, but do it anyway because it seems to solve problems on other Leopard systems.
1.) Disable Time Machine back ups
2.) Open Disk Utility and Run Repair Permissions
3.) Run Verify Disk. If it passes go to step 4.
4.) Download the 10.5.5. Combo Updater from http://support.apple.com/downloads/MacOS_X_10_5_5_ComboUpdate
5.) Run the Combo Updater and restart
6.) Run Disk Utility Repair Permissions again
Then enable Time Machine and keep your fingers crossed.
Let me know if any of that helps.

Can't force quit applications problem during Time Machine backups

I've run into a frustrating problem with Time Machine. I'm using an external 750gb USB hard drive as a backup disk with my Mac Mini; the connection is visa the Firewire 400 port.
When I'm doing anything that's CPU-intensive while a Time Machine is backing up, it is a 50-50 chance that one or more applications will crash. It is impossible to Force Quit them, which means that it is impossible to log out or shut down. The user is faced with a choice: Kill the whole system, and risk corrupting the system hard drive, or yank out the Time Machine disk's connector, and risk corrupting the Time Machine backup. Of course the latter is preferred, and that's what I've done. Thus far, I haven't seen any corruption on the Time Machine drive, fortunately, but in order to work with my system, I have had to disable Time Machine backups while I am working. (I reconnect the Time Machine drive overnight.)
I know from some Google searching that others are experiencing this problem. My question is, has anyone figured out why this is happening, or developed a workaround?
Regards,
Bryan

In the process of restoring my MacBookPro from an external TM drive as we speak. I can say with almost 100% certainty that force restarting (holding the power-button down until the book shuts off) will corrupt your start up disk to some extent.
My problem is that I was away from my network when TM tried to do an update. I'm not sure if TM was actually able to connect to my server but none the less I was on a verizon wireless card and so even a minor backup would have been slow.
I needed to shut the computer down and leave. I have had TM hang when trying to shut down and tried to tell it to stop the back-up (which it tries to do for hours on end and have had to force quit before... had to run disk first aid that time) So this time I figured Id leave the computer on (though unplugged) while I drove home.
I did not close the case until the screen went dark. Unfortunately, it had just gone to sleep (a half hour later) instead of shutting off but I did not know that at the time so I shut the case then.
When I plugged it in in the AM it was dark but not black... I could just see the screen and could see it was frozen. Force restart completely screwed my startup disk. Luckily I have a BU from the night before.
Maybe TM should also be linked to the location, and or connection you are using. So, if I am away from my LAN it will automatically turn off. I also wish I could set it to back up every x hours instead of every hour.
Good idea... just needs some work on the routines. (only an hour left on my restore now)

Hard drive died with a kernel panic during time machine backup

after installing a new hard drive into my 13" macbook pro (mid-09), i used the time machine utility on the os x install disk to restore from my last backup. the restore went well and all my data was fine. however, after about 30 minutes of internet browsing, i got a random kernel panic and after rebooting the computer the new hard drive was no longer being recognized.
i have no idea what happened to the drive (it was brand new, just installed earlier today) but a major concern of mine is that time machine was trying to back up the computer when the kernel panic occured, so i had to reboot in the middle of taking a backup. could this possibly corrupt my time machine backups?
im really scared right now so any insight helps.

New MacBook Pro - continue with Time Machine backups or start over?

I'm unsure of how I should proceed here ...
My old (late 2008 aluminium unibody MacBook) died last month and I now have a shiny new MB Pro. I transferred my data from one of two backup drives I have using Migration Assistant but did not transfer the Pictures folder because the new MB Pro only has a 256GB PCIE drive whereas I had upgraded my old MacBook to a 750GB hard drive. The Pictures folder was 175GB - it obviously couldn't be transferred in its entirety so at this stage I haven't transferred anything at all from my Pictures folder.
Both backup drives I use are 1TB Lacie Rugged external hard drives. I have them partitioned as follows -
Time Machine Backup - 475 GB
SuperDuper Backup - 350 GB
Pictures - 175GB (I only have the iPhoto Library on the Pictures backup)
I was thinking that I could simply continue with the existing backups, however, I realise that will be impossible because the existing backups all include the Pictures folder as part of the 'normal' backup process.
So, should I wipe my backup drives and start all over from scratch with the new MB Pro? Obviously, I don't need such a large space for the Time Machine and SuperDuper backups now so I could re-partition the drives and allocate more space to the Pictures folder (which is the one that continues to grow).
Does anyone else have experience of using their iPhoto Library on an external drive with the smaller PCIE drives in the MB Pro?
I would be very grateful for any suggestions as to how I should proceed.
Tricia

Many thanks for your response Ingo2711. It seems as if we faced pretty much the identical situation.
I've never taken much notice of Time Machine - just let it do its own thing. However, when I go to System Preferences - Time Machine - Options - Exclude these items from Backups and then choose the Pictures folder it shows that the space saved is only 1.47GB (my Pictures folder on my old MacBook is about 175GB). I clicked on the Pictures folder in Finder and discovered that it had one folder in it which is the folder I use for Desktop and Screen Saver and that the size of that folder is, in fact, 1.47GB.
So, am I right in thinking that I can just allow Time Machine to do a full backup without excluding anything and it will see that the new system is different from the previous one or am I missing something? I really don't want to lose the previous backups in case I ever need to go back to something.
Cheers
Tricia
BTW, I'm going to download iPhoto Library Manager and see if I can put my photos in chronological order by year and then just keep the current year's photos on my new Mac and keep the rest on the Pictures partition of my backup drive (which is connected via USB 3) - I'm hoping that the access to the external drive won't be so slow over USB 3.

Can I switch users during time machine backup?

I have a laptop with multiple users.
I am trying to do a Time Machine back-up using a fire-wire connected western digital drive.
Either because I had not backed up in a few weeks, or had updated to 10.7.2, I am not sure, but when I connected the drive to do a backup Time Machine started doing a deep scan.
The preparing phase took several (over 5) hours before the backup would start, but it finally did begin backing up.
It is trying to back up 8 GB of files and is taking a very long time. It backed up 1.5 of 8 GB over the course of the entire day.
Then my kids came home from school and switched to their users.
Looking at the logs, it looks like the backup got canceled when we switched users.
After switching back to the admin user, I am back to the preparing phase again.
I thought you could log out, swtich users etc with Time Machine.
Can someone explain this behavior to me?
Thank you

I just wanted to update all after my experieces:
Time Machine was not the problem. The problem was a defective WD external firewire drive (WD Green drive) which has since been replaced under warantee. Thank you WD for your comiitment.
Whenever I used this drive, I could hear it chugging and chugging away during mount and whenever I was accessing the drive.
I finally checked the drive (WD My Book) with DISK WARRIOR and the thing was toast. Tons of unrepairable hardware errors.
Thankfully the drive was under warantee and after receiving a replacement from WD (no issues with RMA replacement process, kudos to WD) have had ZERO issues with time machine and the replacement drive.
Initial 1st time- time machine backup was ~ 5 hours. (~120 GB of info). (I added the drive to spotlight 'do not index' prefs prior to setting up time machine.)
-This was a HUGE time difference. My prior initial backup with the defective drive was 3 DAYS, yes, DAYS.
If you are having these kind of problems, check you drive with Disk Warrior (Disk Utitlty does not cut it). If Disk Warrior reports problems, it is a hassle, but replace the drive.
Good luck. Karma +1

Microsoft Word for Mac Freezes During Time Machine Backup

Since upgrading to Lion, I have found that when Time Machine is performing a backup that word for Mac freezes. I have all software updates for both Mac and MS. Running on 17" MacBook Pro.
Any ideas?
This appears to be the same issue:
https://discussions.apple.com/thread/2403912?start=0&tstart=0
Thanks in advance.

The Time Machine backup data on the network device is corrupt. The first thing you should do, if that's your only backup, is to make another complete backup to a locally attached storage device. One backup is never enough to be safe. Network backups are less reliable than local ones.
After that, hold down the option key and select Verify Backups from the Time Machine menu in the menu bar (not the Dock icon.) This operation may take a long time. If the menu-bar icon (a clock that runs backwards) isn't showing, check Show Time Machine in menu bar in the preferences.
If you continue to get panics, erase the backup device. With an AirPort device, you do that from within the AirPort Utility application; see its built-in help for details. All backups will be lost, so don't do this until you've backed up to another device. After erasing, select the device again as a backup destination in the Time Machine preference pane. The first backup should be made over a wired connection, if possible.
If you still have problems after erasing the device, it should be replaced.

MacBook shuts off during start up...

When I turn on my computer it's starts to boot up normal but all I get is (and in this order) the Apple logo, a loading bar, and the spinning wheel. The bar only loads to about 5% then after about a minute my MacBook shuts off. I have two questions:
What could be wrong?
What is the shortcut the guys at the genius bar us to check the hardware status?

You can eject a stuck disc several ways, all during startup:
Hold down the eject key, or the space bar, or the mouse button until it pops out (sometimes it can feel like it isn't working, but be patient and try all three).
If none of those work, there are terminal commands we can try...

External Hard Drive ejects during Time Machine Backup

I've read through all the troubleshooting pages that I thought had anything to do with this problem, but none of my error messages seemed to match. This is my first backup with Time Machine onto my external hard drive, and it never gets past about 60GB before deciding that the drive has improperly ejected itself and aborting the backup. The error message from my Time Machine Buddy is below:

My external drive is a WD 1TB drive. The partition for the Time Machine Backup is formatted as Mac OS Extended (Journaled), as is my Macintosh HD. The Partition Map Scheme on the external drive is GUID Partition Table.
I have tried reformatting the external drive for good measure, but this doesn't seem to solve any problems. I also tried searching for the file that the error message says NO Copying for (/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/g ems/net-ssh-1.1.4/lib/net/ssh/proxy/...) but I'm unable to find the files. I can get as far as /System/Library/Frameworks, but can find no folder in Frameworks titled Ruby.
Please help.

The Ruby folder is probably hidden. That is why you don't see it.
You may want to add System/Library/Frameworks to the exempted sync list until you can figure out which file is causing this. You can do this by opening Time Machine Preferences ( > System Preferences > Time Machine) and clicking on Options…
After that click the small + key and browse to the folder you want to exempt from the sync. In your case: Macintosh HD > System > Library > Frameworks
Next hit the exclude button with the Frameworks folder highlighted.
Try your backup again and see if it fails.
