Snowleopard 10.6.8 update freeze at start up

I downloaded 10.6.8 on my imac and it will not boot. It freezes and it will not start up from cd. I've unplug all devices and it is completely locked out. Help!

@jamesofcheney: Do you have Hands Off! installed on your machine? This was the problem on my side. I had Hands Off! 1.2.4 and I fixed my problem by upgrading to 1.3.1. I had the chance to have an old copy of my hard drive though and I could boot my machine from that drive. Here is a trace of what happened on my side:
After upgrading to OS X 10.6.8 through Software Update, my Macbook Pro froze while rebooting. The little spinning wheel under the Apple logo at boot time stopped spinning and nothing was happening anymore.
I then booted from an external drive and I downloaded the update again from here: http://support.apple.com/kb/DL1400 and re-installed it;
At this point, things got worse. I got a kernal panic when my machine rebooted. There was something about com.metakine.handsoff.driver in the dump on the screen. So this gave me a hint on what the culprit could be.
I was fortunate enough to be able to boot in Safe Mode (by holding down the Shift key while booting);
After booting in Safe Mode, I started Hands Off! which warned me that there was a new version, and I installed it.
I was then able to reboot normally (not in sae mode) without kernel panic;
I started Hands Off! and completed the installation (There is an extra installation step that occurs when starting a new version for the first time).
Now, things seem to be working fine, and I am crossing my fingers that I won't discover any other problem due to the 10.6.8 upgrade;
@A Brody: My point in my previous post was to let jamesofcheney know that he was not the only one with this problem, and that it was therefore most probably not a hardware problem.

My mac is freezing on start up. its brand new just opened for the first time. installed the updates and it froze. can anyone help?

My new mac is freezing on start up. after the initial start up, i did software updates and now its frozen. can anyone help?

If this is really a NEW Macbook Pro and this happened the first time you turned it on and did Software Updated then you need to take it back to where you bought it and RETURN IT FOR A FULL REFUND. Then decide whether to buy another NEW unit or move on to something else.
Apple has a No Questions Asked 14 day return policy. Take advantage of that and return this unit. This type of thing should NOT happen on a Brand new notebook.

My macbook keeps turning off and freezing on start up

So like my macbook keeps either freezing on start up or it will just shut off or restart itself
When it restarts itself it will bring up the main screen then this box comes up telling me to hold down the power button and restart it
A friend said it might have something to do with the fan not working or it overheating
But I can have it off all night then turn it on in the morning and it will mess up
It will do it sometimes between 2-4 times
I don't know what is making it does this
I ran the check up things and it said that nothing was wrong?

This sounds like the same thing that has been happening to both my Macbook and Macbook Pro. Some others sound like they have similar problems. This is what I posted in the Macbook Pro area regarding the same symptoms. This is discouraging. These computers are expensive and they should have the bugs worked out better than this.

I wonder if I have similar problems. I have both a Macbook Pro 15" and a Macbook 13"
1st my macbook started shutting itself off unexpectedly. It got more and more frequent. I have done several fixes including: archive and install, sending it in to have a logic board replaced, downloading an updated disc utility repair, and sending it in to have a power component replaced. Now I will be sending it in for a third time and I think they will replace the Macbook machine if this repair doesn't work.
Now my Macbook Pro is doing the same thing. I have had it for about 6 months and it was running fine until now. I ran the exact same software on my 12 G-4 powerbook without any problems. One of the computer people at work said it sounds like a power problem. It happens whether it is running AC or on battery power and doesnt seem to matter what I am doing.
I am waiting for the macbook to be fixed before I address the Macbook Pro because I dont want to have both of my computers in the shop at the same time.
Any suggestions? This seems totally unacceptable for two new expensive computers.

Updater freezes. Shuffle corrupted. Please help.

Before I get started I'll try to be clear on a few things.
UPDATER VERSION IS IRRELEVANT. I've tried with three different versions.
ITUNES VERSION IS IRRELEVANT. This is unrelated to itunes.
Short story: Program problem disallowed safe shuffle removal. It was corrupted as a result. I can't restore the ipod because the updater freezes up.
Longer story: Because of program I tried to run off my shuffle and my schools computer setup, things got messed up and when I tried to eject it it wouldn't let me. So I removed it manually. The shuffle got corrupted and was unreadable.
Seemed like a minor problem since I could easily restore the Ipod. I knew I had lost my files but that wasn't too bad. However the updaters all freeze when the ipod is plugged in or if they start while it's plugged in.
Now instead of just getting an error message when I try to do anything with my ipod the computer seems to be treating it as though it were an empty cd drive or something.
I doubt I can fix things. If I can't can anyone direct me to a replacement form and tell me if I've somehow voided the warranty?

I fixed it myself. The restorer was freezing up but apprently there is a third party one.

It works great. it may help those of you who can't get the updater to recognize your ipod.

Ipod update freeze, firewire problem, possible fix for many.

Hello all,
I've been having a problem with my ipod 3rd gen updating in much the same way as many in this forum have throughout a number of topic threads.
PROBLEM:
During song/playlist/content (not software update or restore) updating function one of two things would happen:
- update would freeze at some point of the transfer (5, 74, 687 songs in to the update) and I would have to force quite itunes and, not being able to dismount the ipod through recommended procedure, I would physically dismount the ipod and receive a scolding for improper dismounting of device.
- system would crash at some point of the transfer yielding the shaded screen and a prompt to restart the computer by depressing the front panel button for two seconds.
In each of the above cases, no matter how many songs that itunes thought it had transferred, I would only have about a dozen songs on the ipod itself, perhaps indicating a bottleneck on the G4 end of the transfer.
DEADENDS FOR ME THAT MAY STILL SOLVE PROBLEM FOR SOME:
- swaping out cables
- ipod software restore or restore to earlier version
SOLUTION:
After contacting Apple support, I was led to the opinion that the problem was with the firewire port itself. This was confirmed by attaching my ipod with my cable to a roomates G5 resulting in a faultless transfer of his song library. I was ready to go out and purchase a new firewire PCI card but decided to research firewire problems in the G4 folder of Discussions. This is where I found the fix to my problem (see links at bottom of document). It would seem that Mac ports, both firewire and USB, have a tendency to bog down after awhile and need to be reset. This can be a addressed by one of three possible solutions. The first and easiest was the solution that worked for me (for other solutions please follow links at bottom of page):
- powered down and disconnected all firewire and USB cables from the G4
- disconnected power cable from G4 (for laptops I would guess that the battery would need to be removed, not sure if that causes any other problems though, please research)and let sit for about 30 minutes.
- reconnected all cables and restarted computer. Ports should be reset at that point
- I took the added measure to restart my computer once with nothing attached to USB and firewire ports and then powering down with front panel button before connecting cables and proceding with final restart.
RESULT:
Faultless transfer of 37.6 gigs of content in less that 45 minutes.

Good Luck

This worked perfectly for me!!!
SOMEBODY PLEASE TAG THIS POST!!!
i have had the problem that everyone has posted about (i.e. - updated iTunes/iPod software and had the update/freeze problem, tried all solutions, to no avail, and was pretty much screwed.)
JUST DO EXACTLY WHAT HE SAYS TO DO (powermac g5, by the way):
1) power down the computer
2) unplug EVERYTHING (usb, firewire, power, monitor, etc.)
3) leave unplugged for 30 minutes
4) plug power back in
5) power up from main power button
6) wait for computer to start back up, then shut down from power button
7) plug everything back in and power up
8) restart once more for good measure
9) update your ipod
10) take a sigh of relief!
you are seriously a godsend...only one thing...I BOUGHT A NEW ONE ALREADY!!! i literally bought it the day that you posted this solution. After a month and a half of trying to fix this problem, i finally gave up and bought a 20GB iPod Photo with applecare...cost me about $380.
no matter, i think i'm gonna sell my "older" ipod to my mom or dad. they'll use it doing whatever they do. plus, that way, if there's any problem, i can fix it for them without feeling bad about screwing over some stranger.
thanks again, this solution worked perfectly.

MacPro 3 OS 10.5.8 freezing at start up

I just installed Photoshop CS5 and during an Adobe aided install of some missing plugins, the support person had me restart my computer. My Mac Pro which has never given me a lick of trouble froze during start up. I ended up rebooting after several tries unplugging and retrying a normal start, I eventually held down the option command P R while rebooting. It did start up but is exhibiting odd behaviors. It froze while I tried to verify disk on my main HD. I decided to shut down and unplug all my peripherals and restart and had the same problem, a grey screen with a progress line at the bottom that freezes before start up. I had to reboot as described above. I am not sure if I should uninstall CS5 or look for a fix. The adobe support person dumped my call when I mentioned that my computer wouldn't restart. I am a photographer who loves using my Mac but knows little about how it really functions. I would appreciate any help you experts could provide.

I have an older copy of Disk Warrior that I bought to repair an external hard drive that I was having problems with.
Did that drive have 10.5 installed on it? What version number of DiskWarrior do you have?
Never realized I could use it sporadically with the Mac to detect problems.
Oh yes!
Would it matter that it is a couple of years old?
Yes it could, it has to be a Leopard compatible version. Is it DiskWarrior 4?
If you have that version, that it'll work on 10.5.8. If not, you'll need that DW4 upgrade at $49.95.
Later you can get a free update to DW 4.2 which will work on Snow Leopard.
I really appreciate your help.
No problem!
I take it you think it is a data problem and not a physical one with my system.
Probably. If you want to, try running your Apple Hardware Test . It's not perfect, but may flag something if it's hardware based.
I am looking at upgrading to OS 10.6. Any thoughts as to if it might improve the problems I am having with Photoshop. My last version was 32 bit, this one is 64.
Yes I believe Snow would work better for you, but to be sure ask that question in the Snow Leopard usage forum.
I am wondering if that can cause problems with start up or if I am dealing with some other type of issue.
Maybe, but I really don't know for sure. I don't run anything that needs 64 bit.

Z10 freezes during start up

My z10 freezes during start up. First I can see the red led on, then the BB logo and "blackberry" on the screen and it stays there forever.
I have tried to update the OS, using BB update software option, at which after resetting my Z10 the green led stays on, though I cannot update it, getting the error message "error downloading Blackberry Desktop Software".
Any ideas ? I need to recover information in the phone's internal memory.
Thank you !!!

So I did the Disc Utility, and the disc was sucessfully repaired. I restarted the iMac and got to exactly the same place as before: "Login window started" where it froze again. I turned it of, restarted in Safe Mode and it froze at the same spot.
Is the next step to try reinstalling the OSX? I didn't see an option to install in place ie leave all my files intact. There's an "Archive and install" option. Does this just archive the system folder and erase all my other files. I'm pretty much backed up but I'd much prefer not to erase the files if I can avoid it.
Thanks

Mac Book Pro freezes on start up

I downloaded the latest software updates sent out today and after the restart my Mac Book Pro now freezes on start up after my screen is completely loaded. I've tried all the fixes listed in the troubleshooting guide, nothing works. I think it might be related to my Earthlink total access program because it doesn't freeze until it almost starts this. Can I remove the latest update some how? Help!

My MacBook Pro is experiencing the same problem. I did find something to stop the freezes though... as soon as the screen is loaded, I disable Airport.... and wait at least 2-3 minutes before reenabling it. Not sure why it works but it does for me.
My problems also started after downloading this update.
Good Luck!

Macbook pro freeze at start up

After putting in the latest security update for OS10.8 my macbook freezes once the desktop appears. Have to force shutdown to get out. can't open any windows or applications. I see dropbox in perpetual update.

AllenJP,
try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does your MacBook Pro still freeze when starting up in normal mode?

You need to back up your data before you do anything else, if it's still possible.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

ITunes freezes during start up

I have an iMac bought last year.
2.7 GHz Intel Core 1.5
8GB 1600 MHz DDR3
OS X Version 10.9.4
iTunes 11.3
My iTunes starting freezing during start up about a month ago. As soon as it begins to sync with my iPhone I get the beach ball and have to force quit. I have tried reinstalling it, starting with WiFi off, and other hints from the forums with no success. Any ideas or help is very much appreciated.

I am having the same problem? I installed the iTunes update and it asked to restart the system... but it never came back up... just stays on the reboot page. How do I fix this?

When I click on Firefox it opens with a box that says "Foxfire is installing your updates and will start in a few moments-. " then it says "Software Update Failed (in blue) with an exclamation mark inside a yellow triangle) The update could not be install

When I click on Firefox the first time it says "Foxfire is installing your updates and will start in a few moments…. (with a green bar)" then it says "Software Update Failed (in blue) with an exclamation mark inside a yellow triangle)
The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again." When I click the ok, Firefox opens up. If I open another Firefox window with the previous one still running, it doesn't give me any of these messages, it just opens normally.
== This happened ==
Every time Firefox opened

If you can't install on top of the current installation then you need to delete or rename the current Firefox program folder to do a clean install.
It is possible that your security software is using or locking files, so you can try to temporarily disable that software during the installation.

Tabs only open in a new window. Ctl T opens a new window NOT a new tab help-last update this problem started. How do I set FF back to open tabs in 1 window

Tabs only open in a new window. Ctl T opens a new window NOT a new tab help-last update this problem started 2 days ago. How do I set FF back to open tabs in 1 window?
There is no plus sign and going into optins and changing settings has not worked. I have uninstall FF and reinstall-keeping my personalization-and that was no help.
Right clicking on FF Icon to open a new tab, or going up to FF drop down tab and clicking on new tab both do not work.
Help everything opens a new window not a new tab. there seems to be no way to reset this or to chose a different optin. I just downloaded new tabs at end addon and it didn't do a thing.

as a first troubleshooting step - does it work like normally when you open & run firefox in [[Safe Mode|safemode]] by pressing the shift key while you open firefox (all other instances have to be closed before)...

Exceeded RAM..was crashing now freezes on start-up screen..HELP!!

My mac is only about 2 mths old.
I've got about 15GB music, lots of tv shows (about 13 series) and yesterday I installed Microsoft Office.
My mac had been freezing occasionally before and I would just have to resart it. The cursor would freeze on the page.
Well as I said yday I installed Microsoft Office and also downloaded 4GB worth of TV shows and another 2-3GB music and tonight it has crashed.
At first it was freezing after a minute or two of being on, no pages would load especially internet pages with lots of pictures.
I've restarted it a lot trying all the different combo's on the discussions/forums but it still seems to just freeze on start up.
Resarting whilst holding down Command-S gives me
"error enabled
uncorrected error
mca error code: 0x0400
model specific error code: 0x2008
other info: 0x00001210
debugger called: <panic>
backtrace <cpu 1>, frame: return adress {4 potential args on stack)
I just put in what I thought might be significant.
It freezes after that page and wont let me type anything..
Have tried resetting PRAM, resarting in Safe Mode, resarting with mac disk that came in box...
Nothing is plugged in.
I totally forgot about my mac having limited RAM :S

All good... I quickly typed in 'fsck -fy' Return
before it froze.
It ran through some checks. Then typed in 'reboot' Return. It booted up. Halleljah!
The cursor was still acting up a bit, jumping around and lagging. I managed to uninstall microsoft office, skype, sims 3 and some other crap I didn't use. Seems to be running perfect now.
That'll teach me to get an external hard-drive...
