Snow Leopard 10.6.4 freezes

For some unknown reason Snow Leopard 10.6.4 freezes randomly. It does not happen too often, but when it does the only way out seems to be to shut down the computer and start it up again.
The only thing it shows is a spinning wheel (not the BBOD) in the center of the screen, but low (just above the dock).
Thinking it might be the HDD starting to have issues, I just replaced it with a brand new one. So the MB now has a clean install (Snow Leopard) that is completely updated (10.6.4, then used migration assistant to move files and settings before swapping it with the old HDD. Everything works fine apart from the freeze).
But the freeze happened again yesterday, and I can not find any other mention of things that could potentially cause this problem.
Any ideas as to the potential source of the problem, how to check, and good suggestions for further actions to avoid a repeat?
Thanks.

My system just crashed again.
I went back and checked the console and indeed it looks like VirusBarrier X6 is the culprit:

The problem is this issue did not exist with the last version of Virusbarrier. The newest version contains many additional services, like Anti-Phishing, Anti-Spyware, a Firewall in addition to their more traditional "Real Time scanning" for viruses. The pull-down menu allows you to disable these all, one by one. So I have disabled most of the "non-traditional" VirusBarrier features to see which ones are causing the problem. I suspect it is the spyware scanner that's causing the problem.
We'll see.
Nothing like paying for antivirus/antispyware SW and it's the one causing the problem!

After uploading snow leopard 10.6 Mac freezes up

After upgrading a desktop Mac from OSX 10.4 to Snow Leopard 10.6 it freezes up. Should I start all over again from the beginning or is there a way to find the problem?

Impossible to answer with information provided

Will reinstall of Snow Leopard help iMac stop freezing?

Hello,
I've been having problems with my Mac freezing. I've tried all kinds of things (verify and repair permissions and disk etc, make sure enough free space, as well as checking fans, disk utility etc) and the problem persists. It's a 24inch iMac that I bought in late 2008 and the problems have been ongoing intermittently for months now. Basically what will happen is that I’ll be using it when it will suddenly freeze and the screen goes blank. The only thing that works then is to restart by holding down the power button on the back to turn it off and then on again. I use it most often for internet (I use firefox) but the issue has happened when doing other things too, so I don’t think it’s related to any particular programme.
I took it into the genius bar and after checking the disks and finding no problem their advice was to reinstall snow leopard. I was the last appointment of the day before a long weekend and the guy was helpful but fairly rushed. The thing is that I had this problem with leopard as well before upgrading to snow leopard, so I can't see how it's related to snow leopard. So, is reinstalling snow leopard likely to help? Would it be easier to upgrade now to Mountain Lion instead and see if that helps?
Any suggestions gratefully accepted and please let me know if there's other information that you would need to know in order to provide any suggestions.
Thanks so much in advance

I have the same model. What I suggest you try next for this problem:
1. Run the Apple Hardware Test. It can't detect all hardware problems, especially intermittent ones like you might be having, but it is still a good first step.
2. Reset the SMC. I'm not sure why but this has fixed some odd problems I have had in the past with my 2008 iMac.
3. If this doesn't help, try running for a while without any peripherals attached to your iMac besides the keyboard & mouse. If you don't see any freezing problems, try reattaching your other peripherals one by one & running that configuration long enough to see if one of them is causing your problems.
4. If none of this helps, go ahead & reinstall Snow Leopard, making sure you run Software Update afterwards to update it to the latest version. The Snow Leopard installer isn't like earlier OS installers. To reinstall the system just run it & accept the defaults. It won't write over or alter your user data or create any "Previous System" folder stuff, so it is a fairly painless procedure. It even performs the equivalent of Disk Utility's verify disk step, so you don't have to do that beforehand.
5. If none of this helps, reply to this topic & we can suggest other things to try.

Snow Leopard 10.6.3 freezing during installation? Please help!

I have a 13" Macbook with Mac OS X 10.4.11 and am trying to install Snow Leopard 10.6.3 (which I bought from the Apple store). I am having trouble with the installation, as it freezes every time I get to a certain point in the "Installing" screen. It was freezing around the 40 min. mark, and so I tried the various options that the installation CD gave me. Such as going into disk utility and doing the "first aid" stuff where everything seemed to check out fine. None of that helped, and it kept freezing at the same point, sometimes going all the way to a screen that says, "Install Failed, the installer could not copy the necessary support files." I double checked all of the system requirements, and I originially didn't have enough memory, but freed up space for the installation.
I then tried the last option on the installer troubleshooting by backing up my files on an external hard drive and then erasing the memory through disk utility. Now I can't get back onto my original computer drive when selecting a startup disk, as it only lets me see the installation CD to select. Erasing didn't help, except that now it freezes at 29 minutes instead of 40. I can't even eject my CD, I'm assuming since there is nothing else for my computer to run on. I'm not a genius with computers, but I was simply following the instructions that came with my software. Now I can't even get back to those instructions, since they were only available on my previous hard drive, and not in the actual disk packaging (which seems kind of silly). I'm planning on calling Apple for support, hoping that I can get free support since I only bought this software a few days ago. However, any help in the meantime would be appreciated! Thanks!

Itunes 9.02, Snow Leopard and iMac 24 - FREEZE UP!

I have 4 mac machines in the home and this problem is only affecting the iMac 24. From reading multiple forums, I can safely say that I am not the only one. iTunes freezes sort of randomly during playback, store browsing, podcast etc...
The only thing I can do is a hard reboot. After I reboot my local Disk needs to be repaired with Disk Utility as the directory counts do not match. I have used the install DVD to repair my main disk over 10 times now.
I have tried all the suggestions on the forums including:
removing plugins
Re-installing iTunes (multiple times)
Rebuilding library
removing SyncServices directory
disabling genius and home sharing
and more
This problem seems to have started after the installation of iTunes 9
I am usually a very happy Apple customer but this has been quite the frustrating experience. Can someone acknowledge this issue at Apple so that I can rest assured that a patch will fix this at some point?
I am out of ideas and search engines to look for answers. Any feedback on this thread is appreciated.

I am reporting exact same problem on iMac 24" (3.06GHz/Mac OS X 10.6.2/iTunes 9.0.2).
iTunes randomly freezes, leaving only the spinning beach ball. Sometimes, if left alone for several minutes, it'll report "iTunes library files cannot be saved (-50)" error. Alas, clicking "OK" to dismiss the dialog window only results in the same message popping up again and again. In all cases of iTunes' freezing and the ensuing beach ball, the Dock seems to go awry, too. The application switcher (command-tab) won't show and clicking on the dock will only freeze it; But, the menubar clock somehow still runs.
After a hard restart, which I am so weary of after having done so many during the last couple of months, iTunes always goes through the long "Checking iTunes library" process before starting up again.
I can't seem to pinpoint the pattern for these freezes.
For now, I have disconnected a Western Digital My Studio II external hard drive used for Time Machine per some online discussion about the lack of Snow Leopard support for that drive by Western Digital and have tossed iTunes' preference files. I'm not ready to rebuild the library file just yet.
At any rate, I hope someone can give us a clear answer. Thank you.

Help! Repeating sequence of Snow Leopard woes! Boot freezes, airport errors

Okay. I seem to be experiencing a cocktail of problems on my MacBook Pro that are similar to those individually reported in other threads. Apologies if this is covered elsewhere, but I've searched and haven't so far found a thread that replicates all my problems exactly and in the same way …
So here goes.
I am on my 3rd install of Snow Leopard. First time I updated from Leopard; second time I erased and installed, then restored from Time Machine; third (most recent) time I erased and installed and have not restored anything except my files from Time Machine.
I'm on a new MBP (2.8GHz, 4GB memory, bought new in Aug/Sept)
Each time I've reinstalled, I've experienced a few trouble-free days in which I think: Ah! Finally fixed it. Then the problems start to creep back in. They are:
1. airport starts to turn itself off. Its icon will be there in the bar, but as an empty triangle. Turning it on will not work (nor will going into preferences, edit locations solution proposed elsewhere). This initially only ever happens when booted from cold. A simple restart will solve the problem.
2. airport icon disappears from bar altogether. Again, only when booted from cold. But sometimes 2-3 restarts required before it will return.
3. system starts to hang halfway through booting from cold or occasionally on a warm restart. It will do the chime, get to the logo and progress indicator, then the indicator will freeze after a short while of spinning and there it will stay. Power off and restart required to get past this stage.
4. (Haven't yet reached this stage on my current reinstall, but happened on the others) After repeated instances of (3) which get more and more frequent, bootup will progress to a blue screen with a progress indicator. Periodically, this screen will refresh and the shade of blue will change; but the system will never get past this stage, not even on a Safe mode startup.
Once I reach stage 4, I cannot get back into my Mac, and will have to use the disc to reinstall. And the cycle returns to step 1.
As you can imagine, I'm getting a little tired of this process. That Apple startup chime is getting mighty tiresome. Is anybody experiencing this grim Sisyphean torment, or is it just me?

Download and run Rember which does more extensive testing. I don't use wifi, so have nothing to say WRT your airport issues. Have a bootable backup/clone? If so, boot with it and see if the problem's still there. It's possible that there's something wrong with the hardware, even though it passes the AHT tests, and you might talk to AppleCare.

Help Downgrade to Snow Leopard due to Constant Freezing from YouTube and Update Failures?

I love the new OSX Lion, however due to youtube being my most visited site, the widespread issue between new iMacs with Lion and Flash Player is bad enough that I would like to return to Snow Leopard. My computer has already frozen and needed to be restarted upwards of 15 times. If I no longer posses the Snow Leopard install disc (never thought I'd need it since I upgraded), is there any way for me to revert to Snow Leopard? I just can't stand the freezing, as well as how long it takes to restart following said crashes, it has rendered my mac nearly unusable. Also, when I run the Software update application, updates keep finishing downloading and then telling me that the download "Can not be saved" which forced me to move my music library to Spotify. Although after 3 days the iTunes update did finish however i did not want to go back to iTunes for fear of future problems. Help?

I've already tried all of those methods using the 10.6.3 disks I bought, they simply don't work as I posted earlier.
All that happens is the machine constantly bleeps 3 times in a row and the DVD drive stops spinning. I know booting from a DVD install disk is a slow process but no matter how long I leave it nothing happens except for the 3 bleeping sounds.
Having scoured the net and spoken to Apple themselves all information tells me these 10.6.3 disks are actually for someone upgrading from Leopard to Snow Leopard.
I have no idea why Apple sold me this version as before I ordered it I explained fully to the sales person what I was wanting to do and they had all the details of this mid 2011 iMac I have bought. So unless the sales person didn't have a clue what they were talking about then I should be able to "downgrade" to Snow Leopard on this iMac as even the specs for this model clearly state on everymac.com that it originaly shipped with OS 10.6.6 (Snow Leapard)
http://www.everymac.com/ultimate-mac-comparison-chart/?compare=all-intel-macs&hi ghlight=0&prod1=iMacIntel041
So there must be somewhere I can purchase these 10.6.6 install disks to "downgrade". Trouble is on Ebay or Amazon where you can buy Snow Leopard most of them are 10.6.3 or "retail" versions with no actual version numbers to let me know I'm buying the correct disk.
Who would have thought setting up your computer could be a mission impossible task and why Apple don't help is simply a disgrace to be honest.

After Snow Leopard install, apps are freezing multiple times

I had this happen with--
Encore
Toast
Illustrator
on multiple occasions. Never had this problem before. Had to restart programs, if not machine, several times.

Hello j:
I am not arguing with you. I simply want to point out that it is not Apple's responsibility (nor any other software developer) to make third part programs work on new software releases. Apple does work with third party developers and makes changes available well in advance of a public release. I had a couple of third party programs that did not work until the developers released an updated version.
I'm having all kinds of programs suddenly close and/or freeze over and over.
If these are Apple programs, post back and someone may be able to assist.

Restoring my System with Time Machine to a new HD without the Snow Leopard DVD

Hi there,
I changed my HD in my MacBook Pro to a bigger one and then wanted to Restore the System via Time Machine onto that new HD. Sadly I dont have the Snow Leopard DVD that was coming with the MacBook. Though I have another Snow Leopard DVD, that I purchased earlier for my older Mac. Now the Problem:
When I try to Boot the Macbook Pro from the older Snow Leopard DVD it always freezes and says: "You have to restart your Macbook. Press the power button until it switches off and then press the button again". But iwill not boot from the DVD.
Is there another possibility to Restore my System from my Time Machine Backup to the new HD?
Kind Regards

You can't use a machine specific OS X install disk with another model of Mac.
It has to do with hardware drivers being on one disk and not applicable to another machine, why you get the kernel panic.
Is there another possibility to Restore my System from my Time Machine Backup to the new HD?
No. You need the OS X install disk.
Choices depending on what your machine is:
1: If your machine with the missing OS X install disk originally came with 10.6.3 or later, call Apple for machine specific replacement disks, there will be a fee of course. That's the only ones that will work.
2: If your machine originally came with 10.6.2 or earlier, you can choose to buy the 10.6.3 retail disk from Apple online, however it contains no free iLife. It comes faster.
3: If your machine originally came with 10.0 - 10.6.2, and you want the free iLife, then order the machine specific versions from Apple, however it might take longer.
4: If your machine originally came with 10.5, and your now on 10.6.x via the 10.6.3 retail disk, you can extract the free iLife from the 10.5 disks using Pacifist from CharlesSoft if you don't want to buy iLife.
You will need this disk regardless in case you need to #18 Reinstall Just OS X or #20 Erase and Install OS X or perform #4-#6 repair proceedures:
Step by Step to fix your Mac
Is there another possibility...
Yes, once you have gotten a new OS X install disk, consider making bootable clones.
It's software that can clone your entire OS X drive/partition (no Bootcamp or Filevaulted) to another external drive and you can easily hold the option key to boot from it.

WindowServer kCGErrorFailure in 40-station Snow Leopard lab (elementary school)

Hello,
I've been teaching computers to 4th, 5th, and 6th graders for nearly 17 years. I started with DOS, went to Windows95, then found out that computers don't need to freeze up 5-10 times a class period, when we switched to Macs (OS 9). Anyway, I say that because I'm so frustrated with our new Snow Leopard lab. It freezes up so often that I feel like I stepped back 10 years.
The bottom line problem is that I my machines freeze up often when running Safari, Excel, or Logging in/out. In trying to determine the source of the problem I found a WindowServer error that happens every time any user logs in. I finally decided to take one machine and completely erase the hard drive and do a fresh install of 10.6.8. Surprisingly, I got the very same error after the install. I followed all the advice I could find here in the community...
permission repairs
verify disk
verify start up volume
restart in safe mode
hardware test
PRAM and NVRAM reset
sudo chown root:amin /
removed cache and sysconfig folders
the photobooth user pic didn't apply
Anyway, I ran the console after each step of the process and got the kCGErrorFailure every time. The truth is, this error may have nothing to do with my freezing problem, but I sure wish I knew what was causing it. Anyway, here's the very first log after fresh install...

Hello,
I've been teaching computers to 4th, 5th, and 6th graders for nearly 17 years. I started with DOS, went to Windows95, then found out that computers don't need to freeze up 5-10 times a class period, when we switched to Macs (OS 9). Anyway, I say that because I'm so frustrated with our new Snow Leopard lab. It freezes up so often that I feel like I stepped back 10 years.
The bottom line problem is that I my machines freeze up often when running Safari, Excel, or Logging in/out. In trying to determine the source of the problem I found a WindowServer error that happens every time any user logs in. I finally decided to take one machine and completely erase the hard drive and do a fresh install of 10.6.8. Surprisingly, I got the very same error after the install. I followed all the advice I could find here in the community...
permission repairs
verify disk
verify start up volume
restart in safe mode
hardware test
PRAM and NVRAM reset
sudo chown root:amin /
removed cache and sysconfig folders
the photobooth user pic didn't apply
Anyway, I ran the console after each step of the process and got the kCGErrorFailure every time. The truth is, this error may have nothing to do with my freezing problem, but I sure wish I knew what was causing it. Anyway, here's the very first log after fresh install...

Is It Safe To Use Final Cut Studio 3 With Snow Leopard Yet?

Because of the many problems I heard about using FCS3 with Snow Leopard when they both first came out, I've held off upgrading my OS from 10.5.8. Now that some time has passed, is it safe to install Snow Leopard without worrying about freezes and crashes with using Final Cut Studio 3? Also, have most of the 3d party software developers updated their apps for 10.6? I'd like to install Snow Leopard for my other apps but not at the expense of FCS.

Hi Jeff, Be sure to also check any aftermarket video cards, firwire cards, all pci cards, external drives external raid / internal raid cards... make sure all are SL compatible and supported. I have not yet upgraded because I'm in the middle of post on a documentary. When I do upgrade, it will be a clean install, not an upgrade. Please let me know how it turns out.

Latest Snow Leopard update software

After the latest update software for snow leopard, my computer constantly freezes. I have to force shut it down by holding the button. I have disconnected everything from it and did the repair disk permissions. Neither has worked. If the computer goes into sleep mode and I wake it up, the moment I try to do anything it freezes. After the force shutdown it has no problems until it goes to sleep again.

A bit of a long shot, but you might try downloading the 10.6.3 combo update and running that (it will run even though you already have 10.6.3). Sometimes that replaces corrupt files that don't get replaced by an incremental update but that cause the update heartburn.

Install snow leopard on a partition of lion

I want to install snow leopard on a partition of Lion. Is that possible?

MarkBerger,
I am not sure whether there is any differences in Time Machine versions on the install discs between the SL install disc and the Leopard disc, but you might try the following if you have the original reinstall discs that came with your machine:
1 - Turn off machine completely using a hard shut-down (hold power button down until completely shut down)
2 - Boot computer while pressing the 'Option' key
3 - Insert the reinstallation disc #1 (if you have two of them) and then select the disc once it appears on screen (this assumes you have a white or light grey screen at this point with drives visible)
4 - Turn on your external disc with Time Machine backup
5 - Once booted to the reinstallation disc, select the correct language and then click button to move to next screen.
6 - Use the 'Utilities' menu to select 'Restore from Time Machine backup' and then follow prompts to restore to working condition
7 - Once booted to desktop, run Disk Utility to repair permissions and verify disk
8 - Try installing SL again (probably want to monitor the install this time round)
Peace.

MacBook Pro screen flickers and freezes after Snow Leopard/Safari 5 updates

Hi guys,
I have a silver 120GB 15-inch MacBook Pro from Summer 2007 with 3GB RAM and 25+GB free space which has recently begun to freeze irrecoverably. The first appearance of these symptoms seems to coincide with my installing the Snow Leopard 10.6.6 update via Software Update.
I'm not particularly well versed in computer technology, but will try to describe my problem as detailedly as possible.
What happens is this:
1. I start the computer as per usual, with only a couple of startup items. Everything's fine.
2. I start working. Use a lot of Safari 5 for browsing websites, often with some kind of Flash or "Flash-type" content such as banner ads, videos, even full Flash designs. I may also have programs such as QuickTime, VLC or an image editor open, if not necessarily "actively" doing anything. Everything's still fine - I'm able to both browse websites and watch videos as usual.
3. After a while of active working - say, 1-3 hours - I notice browsing websites gets a little choppy. Display features such as the file list view in Finder may or may not appear properly. The rotating wait cursor may or may not appear from time to time.
4. Immediately after symptom no. 3, the next time I start to watch a video, either via Safari 5 (say for example something on DailyMotion.com) or a file via QuickTime, something goes wrong.
Following no. 4, one of three things invariably happen:
5a) The video freezes and the entire screen flickers from black to the screen view very quickly two or three times, after which the computer or screen appears to freeze. The cursor still moves, but nothing reacts to it - open windows become completely unresponsive, nor does the top or any other menu react in any way to clicking. The "menu row" of application items, which normally appears when I move the cursor to the very bottom of the screen, doesn't appear. Restarting "blindly" by pressing the Off-button once and pressing R doesn't work. I'm forced to do a hard reboot, after which the computer is once again fine until the next two hours of active working. This usually happens ONLY when I try to watch a video in Full Screen-mode.
5b) I notice the video freezing only just in time, and am able to pause it and "esc" out of Full Screen-mode, and the computer remains operational. However, as soon as I again try to play video in Full Screen-mode, everything described in 5a. happens.
5c) The video stops playing, and the screen reverts momentarily to pale blue before switching to the login screen. I login again with my details, and everything appears to be fine again until the next two hours of active working. The computer "starts up" a lot faster than with a hard reboot. This usually happens ONLY when I've tried to watch a video in its original size, i.e. when not in Full Screen-mode.
This happens 1-4 times a day, and it appears to depend directly on how much work I've been doing on the computer. The less I use it in the course of a day, the longer it takes until the next time it freezes.
So, in a way, I'm able to replicate this problem. 95% of the time the screen has frozen while watching or starting to watch (usually already when starting to watch) video footage, but it has also frozen a couple of times just switching between e.g. Safari 5 and an image editor or browsing a website with a Flash banner ad or embedded video content (which however hasn't necessarily been playing); today, the screen froze when I tried to open a website made entirely with Flash.
Although it could be just a coincidence, I believe this issue first appeared when I updated Snow Leopard to 10.6.6 via Software Update alongside some other pending updates, including as far as I recall one for Safari 5. The update process appeared to have gone well at the time, though, and was not interrupted in any way. I have never had this specific problem with the computer/screen before, though.
I've read a couple of threads here regarding very similar issues with newer MBP models than mine, in which it has been suggested that the fault may lie in a malfunctioning NVIDIA GeForce graphics card. Now I've had that replaced already once because my screen went unexpectedly completely blank after a forced reboot 1-2 years ago (I don't remember exactly), but according to my System Profiler info the card still a GeForce 8600M GT. Can it be failing again?
I've also had some kind of a RAM card failure once. As far as I understood it, one of the RAM cards had fried and was preventing the computer from starting up. I replaced the bad 1GB card with a new 2GB one and the problem was resolved. Before the computer died, there were also other symptoms, but they were not similar to these.
I'm also doing the Apple Hardware Test tomorrow. Any other suggestions, though, than the graphics card?
*Could this have to do with Flash or Safari 5?* Just hear me out. Even though my computer has frozen from watching a video in just QuickTime, Safari 5 has always been open in the background at the same time, and more likely than not with websites with "Flash" content open. And come to think of it, before I performed the Snow Leopard and Safari 5 updates, I used to have daily problems viewing Flash video in Safari 5, the video content either suddenly showing up as "Plug-in Failure" or crashing the browser; I've had both Safari 5 and the Safari 5 Flash plug-in "quit unexpectedly" countless times in the past, almost daily. Sometimes the "Plug-in Failure" could be fixed just by refreshing the browser view; at other times, Safari 5 would stop showing Flash content altogether - Flash banner ads (such as Google ads), YouTube and other Flash videos, everything - until I quit and restarted Safari 5. BUT - since the day I updated everything via Software Update, I don't remember this happening; it never gets to "Plug-in Failure" now. Could it be worth trying to use e.g. just Firefox for a while or is there something (e.g. Adobe Flash) that I could try reinstall? Or am I just clutching at straws here?
Thanks for reading this long, long post!

Do you have access to an Apple Store? If so, it may be worth making an appointment at the genius bar and having them run the test for the NVIDIA problem. Since your replacement logic board still has the NVIDIA GeForce 8600 M GT video chip, it could be starting to happen to your replacement logic board.
I also agree with all of CMCSK's suggestions. Freezing is often associated with hard drive problems. You might also want to run SMART Utility:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It will give you a very comprehensive view of the physical health of your hard drive. If you still have the original one from 2007, it's getting pretty long in the tooth and may be approaching the end of its average useful life of 3-5 years. I just recently had to replace my original 2007 Fujitsu drive.
If your drive is headed south, and is also too small, it may be time to upgrade to a larger and faster drive.
The software update probably didn't cause the problems, but it may have exposed problems that were already in existence.
Good luck!
