System just freezes

I have a weird problem with my Powerbook. The computer will start up fine in the morning but after it runs for about 15 minutes, the System just locks up (Mac OS X 10.4.10). It has to be restarted in order to get past the system lock up. There are no crash logs or error reports that are created.
The PB has been faithful. But, this is puzzling.
No scratchy harddrive noise. It does not shut down. It just freezes.
I was wondering if anyone else has ever experienced this type of problem.
After it locks up the first time, it will restart only a few more times before it refuses to start up. When it has been off for a while, it will restart again and last for about 15 minutes.
If it is started as a target drive, I can get about 25 minutes before it locks up.
Help please.

Tony:
Sorry your luck did not hold out. Incidentally, the folder in the Trash was essentially user font caches, which are Trashed during Safe Boot in Tiger. These can sometimes cause hangups or other issues.
When your computer locks up again, note the time. After you restart go to Applications > Utilities > Console. Check the Console log to see exactly what was happening at the time of the lock up.
My guess is that the AHT will show nothing helpful. I think your issue is essentially software related. Of course, I cannot guarantee it, as I do not know that for sure. I will be interested to hear what you find out at the Apple Store.
Cheers.

Emac taking 1/2 hour to load, then system just freezes

Very recently, over the past couple of days, when I switch my eMac on it takes a good 20-30mins to load up. Then, when you try and open any application, eg. Safari, it just freezes and nothing works. You have to take the power cord out to turn the thing off. Does anyone have any ideas? Could it have some sort of virus as I was not aware of many viruses out there for Apple?
Any help is much appreciated as I was about to backup my music on iTunes this week and I think I now may struggle and lose all my music? (I know, stupid me and my fault :o) )
Many thanks,

Pulling the power cord on a running Mac will most likely damage the disk directory; a damaged directory could cause the symptoms you describe in the first place. It's marginally better to force a shutdown by pressing and holding the power button for about 5 seconds until the display turns off. Use your OS X Install disc to boot the computer and run Repair Disk, as described in Using Disk Utility and fsck, and take note of any errors reported. If Repair Disk reports making repairs, re-run it until it gives a clean bill of health or reports being unable to make repairs. DiskWarrior can often repair directory errors that Repair Disk cannot.
Do you recall how much free space is on the hard drive? If the drive is nearly full, the Mac may not start at all or may perform erratically. You might in such a case be able to Start Up in Safe Mode and manually clear enough unneeded files to free up 5 GB or so of free space on the hard drive. Whatsize can help you find large unneeded files, such as old .dmg disk images from installers you've already run. Since your profile shows OS X 10.3.x, you may also want to refer to Free Space Disappears.

System Keeps Freezing

Hi Guys
I really need some help with this as it's really starting to wreck my brain. My iMac is running the latest software version 10.6.8 but what has started to happen is that if I have anymore then say 3 different programs open the whole system just freezes and it stays like that untill I force it to turn off by holding the power button. I'm thinking the maybe Safari is behind it all because it always seems to do it when Safari is open. I lost about 4 hours work of work yesterday and well lets just say some words were said to my iMac that I taught I'd never say to an Apple product. Has this happened to anyone else and if so how did you go about fixing it so that you can actually rely on it again. Seriously as I'm writing this I have no idea if I'll even get to post it.
Here are the specs of my iMac: 27" iMac, 2.8GHz Intel Core i7, 8GB 1067 MHz DDR3
Oh and it doesn't even have to have that many programs open. I was on youtube this evening and the only thing that was going was Finder and Safari and all I did was while a video was playing clicked on a different video and well it's like Safari paniced and just froze. Seriously what's going on with it, please guys I would be thankful for any help or advise with this.
All the best

Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
Restart your computer when done.

While browsing online tonight my Wi-Fi failed and then after restarting I noticed that I can no longer swipe "back" on websites...when I swipe back to go to a previous page the browser just freezes – can’t click anything or navigate to another site – I have to close the browser and reopen it.
This happens in both Safari and Google Chrome with both Trackpad and Magic Mouse.
Also noticed that I can no longer scroll down in iCal… All the other gestures seem to be responding normally.
Anyone have advice as to how I can fix this?

Help! System keeps freezing

I have recently bought the new imac 21.5" running Snow Le opard(last month infact) and transferred my data from my previous imac running Snow Leopard using set-up assistant. After a couple of weeks my system froze and the only way to get out was to power down with the power button. After re-starting I was getting the file sign with the question mark, showing that the computer couldn't find my hard drive. After re-startingfrom the Snow Leopard install disk it still couldn't find my hard drive, so I powered down again and left it til the morning and tried again starting from the boot disc - from here I saw that the hard drive was verified so I repaired the disc and permissions and restarted - everything was fine, no hard disc problems. However, this has happened now four times, the system completely freezes, I have to do a shut down and encounter the same problem each time, although after a few hours I can re-boot and get everything up and running. I thought originally it was a problem with an open application but the last time it happened (a couple of hours ago) I had nothing running, I had just turned on screen sleep. I am wondering if my time machine back-up drive may be the problem but not being computer savvy I haven't a clue. I would be very grateful for any advice given as I don't really know what to do next

I experienced a different reaction from my Mac book pro after installing wwan.
I actually connect to the internet using a Merlin data card for which this update was made but I live in Greece. What happens is my menu bar keeps quiting and coming back up every ten seconds or so ad noseum. This prevents me from doing pretty much anything since iTunes comes to foreground every time the menu bar gets going (every 10 sec). I spent all of yesterday trying to figure out a solution to no avail. I really need to unistall the wwan nightmare so if anyone from apple is reading this DO SOMETHING. I NEED TO GET BACK TO WORK!!!. And next time you come up with an update like this try to make it network independant or something.

My date/time is incorrect. System pref freezes everytime I try to click date/time. Safari won't let me search the web, if i type in any link it won't respond.

I downloaded mavericks 10.9 everything has been working fine and now I turned my macbook on and the date had been changes. It now will not let me get into the date time tab in system preferences and everytime i try to click it, it just freezes and has to be force quit. This is affecting my safari. None of my top sites come up now when opened and it usually opens right to my homepage which is apple but isn't working now. Any suggestions?

I have decided to dedicate this thread to the wonderful errors of Lion OSX. Each time I find a huge problem with Lion I will make note of it here.
Today I discovered a new treasure of doggie poop in Lion. No Save As......
I repeat. No Save As. In text editor I couldn't save the file with a new extension. I finally accomplished this oh so majorly difficult task (because we all know how difficult it should be to save a file with a new extension) by pressing duplicate and then saving a copy of the file with a new extension. Yet then I had to delete the first copy and send it to trash. And of course then I have to secure empty trash because if I have to do this the rest of my mac's life I will be taking up a quarter of percentage of space with duplicate files. So this is the real reason they got rid of Save As: so that it would garble up some extra GB on the ole hard disk.
So about 20 minutes of my time were wasted while doing my homework and studying for an exam because I had to look up "how to save a file with a new extension in mac Lion" and then wasted time sitting here and ranting on this forum until someone over at Apple wakes up from their OSX-coma.
are you freaking kidding me Apple? I mean REALLY?!!!! who the heck designed this?!!! I want to know. I want his or her name and I want to sit down with them and have a long chat. and then I'd probably splash cold water on their face to wake them up.
I am starting to believe that Apple is Satan.

System wide freezes becoming too frequent

If anyone has some insight about where I could track down what might be causing my entire system to freeze would be highly appreciated! The issue doesn't seem to be application specific, and I've run hardware tests and all the other standard maintenance utilities, which all state everything seems to be ok? One possible suspect I thought it could be was my 2 HDs set to cable select, which I read somewhere can sometimes cause issues. So I switched them to master and slave. After doing so, I ran disk utility to repair permissions and it completely locked up again! I can't even force quit! The complete freeze before that, happened while using safari, so thats what I mean by it doesn't seem to be app specific. Another odd thing about the freezes is sometimes I'll get the strange transparent grey screen with the multilingual white letters telling me to restart by holding down the power button, but other times it just locks up with no wierd screen. This has only seemed to become an issue over the past couple of months or so. I'm not unix scripty savy, but is there some kind of command I can use in terminal or console to possibly find some type of log about the last few strings before a freeze? The panic.logs in console show this

System wide freezes since 10.5.5

Ever since upgrading to 10.5.5 I've noticed the following sort of system-wide freeze on my iMac.
First, one application becomes unresponsive; you get the spinning beachball of death; you can still move the mouse around and click; every application becomes unresponsive, including the Finder. Only a hard restart works.
At first I noticed the problem in iChat, and looked into that. Hey presto, other users are experiencing the same problem with iChat, so I wrote to Apple/feedback and sat and waited. I stopped using iChat, and then found it happened in iTunes. Look at the iTunes discussion, and yes, there it is again, other users having the same problem.
I've repaired permissions, run Onyx, done everything I can think of.
Console doesn't have any useful (to me) messages. It says:
26/09/2008 18:47:48 mDNSResponder[17] Failed to obtain NAT port mapping 00048CF8 from router 192.168.1.254 external address 0.0.0.0 internal port 5353 error 0

That kernel bootcache looks ominous, but I have little idea what it means. I wonder whether it's something to do with Time Machine backing up. Of course, the above might just be totally unrelated to what's going wrong. (Looking at Console is I find rather like looking at a medical dictionary; it's truly frightening, but most of it never in practice seems to be a problem.)
Anyone else experiencing random system freezes only since 10.5.5? Anyone suggest what else I can try or look for in Console to pin things down a bit more?

Hello all,
Let me chime in on this also... I also experienced freezes immediately after I updated to 10.5.5 from 10.5.4 about 10 days ago. I had never had my Mac (Black MacBook with 4GB or RAM) freeze that much, so I concluded that it had to do with the update.
After multiple freezes, I brought the Mac to the Apple Store where a Genius did a disk check, hardware check and everything checked out OK. However, the random freezes remained. They then did an archive and install *back to 10.5.4*, but same thing, freezes remained. At random intervals.
Around that time, I noticed that if I waited long enough, the machine would return from the freeze and everything would operate normally after that.
I seem to remember that the first ever time I noticed the freeze was when I was working in the Mail application.
After my fifth successive daily visit to the Genius Bar, where they offered to completely format my internal drive, install a fresh copy of 10.5.4 and re-load my data back in. On this, they completely failed me, they returned my computer with half of the applications missing (the iPhoto application was not even on the drive), and my data partially restored.
I then decided to re-format my drive once again, use the 10.5.2 Install Disk that came with my Mac to freshly install the OS. Then immediately thereafter I downloaded the 10.5.5 combo installer and used it to upgrade to 10.5.5. Then, I selectively copied files from my Time Machine backup hard drive back to my internal drive.
Time Machine did not work for me when trying to restore e-mail mailboxes. It only partially imported the mailboxes I needed. Instead I had to do an "import mailboxes" from the Mail application and point it to the mailbox location on my Time Machine backup.
So, now I have a system that is lean and clean, I didn't install any "major" other applications using installers, just a few applications I drag-copied to the Applications folder.
The machine ran fine for a day or two, until I tried to move some mail from my inbox into another mailbox. Boooom, spinning beach ball again. I let the machine sit for about 5 minutes, and it came back. But this indicates that there is still an issue.
Since I also experienced this problem after going back to 10.5.4, I am wondering whether the 10.5.5 install does affect firmware or other device 'hardware' functionality that remains, even after reverting to 10.5.4. This is the only reason I can come up with for why the problem still existed when I went to 10.5.4.
Anyway, this post does not provide a solution, but merely some other data points.
Oh and by the way, I had never even started iTunes before this problem showed up again this morning. So, not sure whether it is related to iTunes.

Hi. I cannot launch prem elements 9 any more. It gets so far, then just freezes on the purple screen

It is driving me mad! When you launch, it'll get to the "open project or "new project" window. If you press "open project" it just freezes after a while, if you go "new project" it will ask for a title then freeze on the blank purple screen. It used to work fine. I have tried uninstalling it and re-installing from the CD I bought but to no avail. What should I do?
Cheers

What computer operating system is your Premiere Elements 9 running on? Are you running the program from the 9.0.1 Update?
1. Make sure that you are set for Run As Administrator and running from User Account with Administrative Privileges; you have the latest version of QuickTIme installed on the computer with Premiere Elements 9.0/9.0.1; your video card/graphics card driver version is up to date according to the web of the manufacturer of the video card/graphics card.
2. If no help from "1", delete the settings file named Adobe Premiere Elements Prefs file. Assuming you are working with Windows 7, 8, or 8.1 64 bit
Local Disk C
Users
Owner
AppData
Roaming
Adobe
Premiere Elements
9.0
and in the 9.0 Folder is the Adobe Premiere Elements Prefs file that you delete. If that does not work, then delete the whole 9.0 Folder in which the Adobe Premiere Elements Prefs File exists. Make sure to be working with Folder Option Show Hidden Files, Folders, and Drives active so you can see the complete path cited.
3. If that does not work, the go for new installation files from the following web site and then install them inserting your purchased serial number
http://prodesigntools.com/photoshop-elements-9-premiere-elements-9-direct-download-links.h tml
It is critical that you read the "Note: Very Important Instructions" at that web site; otherwise, you will get an Access Denied message.
In general terms,
a. Is your computer optimized - ccleaner run through (regular and registry parts)
https://www.piriform.com/ccleaner
b. check for pile ups of preview files, conformed audio files, conformed video files?
Let us pause here while your review and consider the above.
Any questions, need clarification, do not hesitate to ask.
Thank you.

System optimization freezes during Itunes 7.6 upgrading

Hi, the last step (system optimization) freezes during the Itunes/Quicktime/Imovie upgrading.
What can I do ? Thanks for any advise.

+Now I get bluescreen every time I try to open or configure Quicktime or even I if my Quicktime-Plugin for IE or Firefox starts...+
What numerical and text codes are you getting with it? (ie 0x\[zeros/letters/numbers] CAPSANDUNDERSCORES)
If the blue screen mentions a specific file (such as, for example ati3duag.dll), let us know what that is called too. (Exact spelling, please.)
Here's a reference on the sorts of things i'm asking about:
Troubleshooting Windows Stop Messages
If you're just seeing a "flash" of a blue screen, we can use this technique to make hidden blue screens appear for us:
1) Open your system control panel (On Vista, go "Start > Control Panels", click "Classic View", click "System").
2) Click "Advanced System settings".
3) Click the "Startup and Recover" section's "Settings" button
4) Verify that under "System Failure" the "Automatically restart" checkbox is not checked.

Windows media player causing system to freeze

My system ran fine for a year or so. Recently my system started freezing almost randomly, mostly when watching videos. I tried using different video players however nothin seemed to change. I tried eliminating all the usual suspects but nothing seemed
to stop the freezing. I finally removed windows media player and the freezing seems to have stopped. I'm not looking for a solution as I'm perfectly fine running without wmp. I just wanted to let the community know about this issue.

Hi,
Since you mentioned that different video players however nothing seemed to change, I suspect there also might be caused by the incompatibility of video card.
Try the install the latest video card applied to your computer for test.

ITunes causing whole system to freeze?

Hi
There are a lot of questions on this forum which are similar to this, but I have not found one that actually replicates the same problem in the same conditions.
Today I was listening to iTunes and had a bunch of other applications open. For no apparent reason, the whole system froze up on me. By this I mean: the mouse no longer responds, keyboard no longer responds, the colon that flashes the seconds in the clock stops flashing (I have that turned on so that I can see when the machine is really frozen), and all the keyboard-shortcuts like Option-Command-Esc (Forced Quit dialog) or Ctrl-Eject fail to work. Even the Ctrl-Command-Power doesn't work (for forced Restart): instead I have to hold the power button for a few seconds and the computer shuts down, but does not restart. (This is what I mean by the 'whole system freezing'). There is no warning, no beachball spinning, and the G5 does not even seem particularly hot (the fans were not blowing hard). So I am completely at a loss to understand what's going on.
Thinking this was a one-off event, I restarted, ran a "Verify permissions" and "Repair permissions" (was this a mistake?) and ran a few applications (Mail, Safari) all of which worked fine. Then I opened iTunes again. It opened OK. I then closed the window, which worked. Then I quit iTunes. This caused the whole system to freeze again, exactly as before.
I have repeated this cycle a couple of times. iTunes will open, will even start playing a song, but on Quit the whole system freezes.
More recently I found that the system froze with iTunes just playing a song.
What then happened was that I looked for help on this forum, found too many cases of iTunes doing strange things but none with my configuration, and thought (perhaps recklessly) that I should update iTunes (from 6.0.4 to 6.0.5). This seemed to work perfectly. Except when I opened it, and played a song, within seconds the whole freezing thing happened again, exactly as before.
So, apart from giving up on listening to music in the office, what is to be done? I am able to run other applications OK (I'm writing this within Safari), so it seems to be an iTunes related problem. I had no unusual devices connected (in fact nothing except keyboard, mouse, monitor), and no iPod connected.
Does anyone know what to do about this?
(I'm using a Power-PC based dual G5 which is only about 15 months old).
Thanks in advance.

Just an update (I'm answering my own post) in case anyone else has this issue:
I managed to get iTunes to stop causing hard crashes. I went through the repair disk procedure outlined here:
http://www.thexlab.com/faqs/repairprocess.html
Including running Yasu at the end with most of the boxes ticked, to clean caches thoroughly.
And I also trashed all the iTunes preferences files. The first time you run iTunes after this you have to answer some questions (as it resets the prefs) but you can always restore your settings manually afterwards.
So far so good -- iTunes launches, runs, and quits without crashing the system.
I guess this might not have been an issue with iTunes itself. The damage was probably done when the first crash happened and I had to use the power button to shut down. I still don't understand what caused the first crash, though, and Yasu seems to have deleted the panic log so I'll never know.
