OS X :: Snow Leopard Freezes - Hangs And Unusable
May 5, 2010
I have a unibody Macbook Pro running OSX 10.6.3. Everything is up to date but the computer is now on its second hard drive and fresh install of OSX and is still unusable. After the hard drive was replaced, it worked flawlessly for an evening. However, the old symptoms reemerged the next morning. Symptoms: very slow to boot or freezes on gray screen with status circle frozen grey circle with slash through it on boot
once it boots, if it does boot, the beachball constantly spins/freezes... I have literally no software installed on the fresh install and it still does it when attempting to boot in safe mode Also, the hard drive when checked gives the following errors even after I repair them in drive genius (the same errors the old drive reported):
invalid file count
invalid directory count

A few months ago I had a problem with my Macbook Pro, (late 2009 model, 15" 2.53 ghz) that many users with Snow Leopard have, the random 30 second freezes. I simply reset the PRAM and SMC and I never encountered it again. Now, out of the blue, on Sunday (yesterday), I started experiencing these hangs again, but worse. The night before I had been browsing the web and my battery went to reserve and shut down, so I plugged it in and when I awoke and turned it on I started experiencing problems. I figured I would try the same fix, and it almost seemed to make the problem worse. Now if I shut down the computer via "apple -> shut down", then turn it back on and log in etc., from the first few seconds the machine hangs. If I open a folder I get the immediate beach-ball and the machine is un-responsive for anywhere from 1 minute - 5+ minutes.
I have read a lot of fixes for this problem, but most of the people's problems resulted from using Safari or Spotlight. I strictly use Firefox and very rarely even open Safari, and I think I've used Spotlight maybe 3 times total, none in the past few months. So far the things I've tried are:
- Reset PRAM
- Reset SMC
- Run Disc Utility and verify, repair etc. (from SL install disc)
So I'm wondering right now what can I do? Its finals week right now and im in college so wiping my HD is not an option. I feel like there is just something hanging the computer but I can't find the culprit.

I have random hangs in OS 10.6.6, I have been noticing these hangs *more* after a period of inactivity (screensaver, after inactivity of 20 or more minutes) , but I have had the system hang on me while I am using it actively as well.   OS 10.6.6 has been on this drive since 7/2011 , without hangs but I recently upgraded Firefox to 10.0.2, - perhaps a factor?Â
Energy save set to never for sleep on either CPU or display.  I do put to sleep if I am leaving for a while.Â
FYI On Launch, my MacPro opens Mail , iCal and Firefox. The Mac is a January 2007 Mac Pro Quad core 2.66gh.  I never had a single hang with the computer until this. Â

My iMac has slowed down signficantly recently and sometimes hangs at log-in or very occasionally at other times. The screen grab of the activity monitor shows the amount of memory 'used' at log-in with no software open - is it normal for half the memory to be 'used' already?

I have a applescript that sometimes hangs (this is on a blind server). reason is that the application (JSMS, it sends text messages via my mobile phone account) can not connect to the server. it than pops a message saying so, but as a result the script does hang and interferes with other stuff.
is there a way to have the script stop (would 'try if' do this?) or alternative is to force quit this script after 10 minutes with an other script.

After recently doing a fresh install of Snow Leopard, it was working great for about a week, and now it hangs at boot and flashes the Apple Logo, a NO sign, and a folder sign. I booted in verboose mode and it say that it could not load drivers.
I had this problem before and I used Leopard's (10.5) Archive and Install feature to fix it.
Where is this located on SL (10.6) ? I DO NOT want to loose my data

Recently Snow Leopard has become one slow ass OS, and I originally though it was because I was going low on HDD Space I was at 11GB free, went and deleted a lot of stuff and it was still slow, currently on 13GB, but it doesn't seem to of been that. I am now thinking it may have something to do with deleting the preference files for Spotlight because it wasn't working correctly (but that made it worse, won't find Apps).
But I am not sure if that is it either, CPU is not really used much either, and all that is happening is Beach Balls 24/7 so is there anything I can do to find the root cause of the issue before doing a fresh install of Snow Leopard (which will take hell of a lot of time as I need to ask my parents to send it back, so would rather there is a fix without reinstallation).

All I get is the grey screen and the little circle with the rotating fan blades. Then they stop spinning and it just hangs.
I cannot boot up. Is this a bad hard drive? Â Are there other keys I could hit to make something work?

I've got this peculiar problem with my MacBook Pro Intel Core i5 running 10.6.8 with all the updates. Whenever I open the computer after logging out, the login window hangs. The insert bar in the username field doesn't blink and I get the spinning beach ball. Sometimes there's no cursor at all. If I close the lid without logging out there's never a problem. But of course that's not an aceptable solution.
I can not reproduce the problem with a fresh account, so I assume there's something wrong with my account. I've had this problem ever since I setup my original account. I've gone through the system.log and I do see some errors during the time the computer goes to sleep after I logout, but I don't know if they are serious or normal warnings.

My Mac Pro hangs up midway through loading Excel spreadsheets, small and large. I've tested the 14GB of ram with no faults. Tried two different new versions of MS office - school and business to no avail. Maybe video card?

Over the past month I have encountered a number of bugs with Snow Leopard on my MacBook Pro (mid 2006). Ever once in a while, usually during high performance task (like watching flash or encoding with handbrake) the temperature of my cpu will spike to 85-90 degrees celsius and then the system freezes.
During this freeze, I can still move my mouse, but I am unable to click on anything on the dock or any program. Moving the mouse over the dock does not invoke the magnification either. I have to do a hard reset to fix the problem.
Also every once in a while, a long blue horizontal line will appear in on the screen. (sometimes their in iChat windows, sometimes safari, and sometimes the desktop as shown in the photo).

i got a white screen when i booted up last night, so i saw it as an opportunity to upgrade rather than trying to fix it. I popped in a fresh copy of snow leopard, it made my white screen boot up. before installing, i opened disk utility and erased my hard drive, and it automatically made a single partition, titled "untitled" and mounted it. i installed to "untitled" and turned install log, and the progress bar is empty. time remaining: about 30 minutes log: checking catalog file is the last line, and it's been there for over 1 hour. i restarted and now it says "volume headers need minor repairs" "repairing volume" and hangs there now.

I have a 2009 8-core running Lion. It has now starting hanging (desktop visible but no response to any input device). I have run Disk Utility and Apple Hardware Test from install DVD (full test) and it finds no issues. Any thoughts as to how to investigate further. Sounds like a memory leak in an app somewhere, but none are left runnIng.Machine is ok when being used but then is hung when left for a few hours. If I take to Genius Bar I assume they will run AHT and say no faults can be found.

Did an upgrade install from 10.5.8 to SL (MacPro early 2008, 8800 Nvidia). Didn't use the Mac for a couple of hours - when I came back I had a black screen and no way of reviving Mac (only forced shutdown via power button). this happened twice. Did never have a problem previously.

I bought a used MaxBook (2,0 GHz Intel Core Duo , 2 GB RAM, 80GB HDD) and try to install 10.6 Snow Leopard (Family License).The MacBook HD doesn't have any data on it, as the pre-owner completely cleaned the HDD. I put the SnowLeopard CD in the CD-Drive and press the C-Button during booting and start the install process according to the dialog that shows up.The installation starts and shows me in the beginning it will take 34 minutes to install. The process continues till the countdown shows 28 minutes’ and then the installation process freezes. I only here some repeating noise from the CD-Drive but nothing happens. I tried this process now several times, I was waiting for hours that the install may continue, but no success so far.... Does somebody have any idea what I could do install 10.6 successfully? I don't think it's a license issue, but I want to add that I also own a MacMini and with the same install CD was successfully installing 10.6 on the MacMini.

Odd freezing occurs when trying to log off. It requires me to hold down the power button and basically restart the machine. Is this a sign of a virus infection, or have I done something else I don't know about?

Wondering if this is just me... I have a 17"MBP, 8GB, 10.6.1; having occasional, temporary freezes ("pauses" perhaps) where there is no beach ball....just all activity stops for 20-30 seconds and then it resumes like nothing happened (and catches up on all of the clicks and such that happened during the pause).
This often, but not always, happens when switching spaces (I have VMWare running XP in a second space).

Since I use Snow Leopard I get randomly (around 1 to 10 ) freezes. When I get it I can click some applications but can't make changes in it. The beachball keeps spinning for some seconds and after the wait I can just continue working. I first thought it was Firefox, because it almost everytime happens when I am browsing the web, but I get the same with Safari.
It's getting verry annoying now :-(
I already checked:
- Repair disk
- Repair disk permissions
- Run Apple diagnostics
Repairs my 1.5 year old mbp already had:
- 2x keyboard
- Topcase
- Logicboard

I have had a string of bad luck with my mac, a couple of days ago the screen started flickering and my mac froze (could still move trackpad mouse, not click). It started up fine again.. It did this a couple times more (had to restart pressing power button). Then it froze evereytime I put the power cable in it. I solved this problem with an PRAM reset.
But now it still freezes up, the screen will start flickering and i can only move the mouse. When i try to reboot it gets stuck on the grey screen. only once every 20 times Ill get into the os.
I have tried a pram reset, holding the power button, safe mode, hardware test (no probs found), starting up without external devices.
It wont boot from the cd if it is stuck on the grey screen...
Could someone may be tell me what to do? thinking about bringing it to the store tomorrow .

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?

Only a laserprinter is connected. Sometimes I can work for a few weeks without problem, but then the computer freezes. The computer sounds 3 monotone chimes in a row and repeats this, keyboard an mouse become inactive till I do a hard shutdown.Took the computer 2 times to the Apple store, they tested for a week but apparently nothing happened then.

I have a mac pro running leopard (purchased in 2/08) and it was running beautifully for almost 2 months with no hangs, crashes or freezes. Then, for some reason, today when I turned it on, it would not boot. It would get to the apple logo, then just sit there for a few minutes, then reboot itself and the same thing would happen. I pulled out the ethernet cable, unplugged all usb except keyboard/mouse and it would then (sometimes) boot into the system, log me in and present me with the UI.
I then quickly performed a soft reboot and it would get to the desktop. However, I can only use it for anywhere from 30 seconds to 5 minutes before it would completely lockup. The clock freezes, the mouse freezes and it just sits there forever. I have tried booting into Vista (BootCamp) and it also freezes before startup is complete. If I hold down Option and then select the System disk, it will either just hang forever or get to the desktop and then freeze again....................

I just purchased my mac book pro on the 18th of may from an apple store, brand new. I decided to upgrade the RAM myself since it is a much better deal, however once I replaced the RAM my computer began to run much slower and it began crashing (showing a gray window that says "please restart your computer" in many different languages) so i restarted my computer and the problem continues, after 12min of running that window appears. I replaced the RAM with the original and the problem still continued. I have run normal hardware tests and extended hardware tests as well as PRAM reset and still nothing changed. Does anyone have any idea what is going on? I'm totally lost on what is going on with my brandnew macbook pro!I should also add, I have been running the extended hardware test multiple times to see if it will crash during that and after 1hr it hasnt crashed yet.

I own two Intel-era Mac Pros, one at work, the other at home office.couple months ago both started having the same problem: a mix of freezes/hangs and weird graphical artifacts showing up on the screens.Usually I need to reboot. Usually a reboot fixes the problem for a while until it recurs. If it was just one computer, I'd figure disk problem or graphics card.But the fact that both have been affected at the same time makes me suspect some software issue or possibly a trojan/virus.

I have a mid-2008 (June) MBP 15". Just upgraded to SL last night. I am having a serious issue with time machine. I've been using it with the same external HD since I bought my mac last year. No issues up until I installed SL last night. This morning (my first backup since upgrading), time machine started backing up (~ 9Gb) but just stops at around 300Mb. The clock keeps spinning, but there is no change in the amount backed up.
I'm reading that other folks are having this issue as well. Has anyone figured something out? I've run disk repair (nothing found), restarted my mac & external HD (several times each), and cancelled and restarted the time machine backup (several times). Each time it freezes at a different amount (i.e. 34Mb, 284.2Mb, etc...).

I have a 20" iMac mid 2007 2.4Ghz, 320GB, 2Gb machine running Snow Leopard. Today I turned it on and it was running fine. But around three hours of using it suddenly froze. I had to force the turn off using the power button. When i turned it back on it took about 4 mins to get to the login screen. Once I logged in the spinning wheel came up and the only think that loaded was the Spotlight sign. This kept happening until about the third time of turning it off and on. When it finally completed login. But it is now extremely slow and it just about freezes when I open more than one application.
