Imac machine crashing on OS X 10.6.8

I bought this iMac last year with the i3 processor 4GB RAM and 500GB HDD configration running on OS X 10.6.8, and it was running very well. But since last week the system is crashing all of a sudden, even this happen when there is no specific application running on it. Also as soon as the system crash it restart automatically and then it crash again without even finishing the startup process and it does the same again and again. I also tried to find the root cause and have a look to the crash report but didn't find the report in the begining but when I found it it was blank.
To resolve this i thought it would be due to some bug in OS and I re-install the complete OS and also updated to the latest versions afterwards. It worked very well for 2-3 days and today again it crashed twice. I am worried and very upset.
I hope you guys may help!!
Thanks

Hi, Thanks to both of you
The system is running very well now and I think the bug was in the security update itself. Much appreciate for your help.

my iMac has crashed...was told I need a new hard drive.....meantime I bought a mac mini.....I had an external drive connected to the mac....and was using time machine for backups....so....how do i move itunes music files to my new mac mini from the external drive?

Turn Time Machine OFF temporarily in its preference pane. Leave the window open.
Navigate in the Finder to your backup disk, and then to the folder named "Backups.backupdb" at the top level of the volume. If you back up over a network, you'll first have to mount the disk image file containing your backups by double-clicking it. Descend into the folder until you see the snapshots, which are represented by folders with a name that begins with the date of the snapshot. Find the one you want to restore from. There's a link named "Latest" representing the most recent snapshot. Use that one, if possible. Otherwise, you'll have to remember the date of the snapshot you choose.
Inside the snapshot folder is a folder hierarchy like the one on the source volume. Find one of the items you can't restore and select it. Open the Info dialog for the selected item. In the Sharing & Permissions section, you may see an entry in the access list that shows "Fetching…" in the Name column. If so, click the lock icon in the lower right corner of the dialog and authenticate. Then delete the "Fetching…" item from the access list. Give yourself read access if you don't already have it. Click the gear icon below the list and select Apply to enclosed items from the popup menu.
Now you should be able either to copy the item in the Finder or to restore it in the time-travel view. If you use the time-travel view, be sure to select the snapshot you just modified. If successful, repeat the operation with the other items you were unable to restore. You can select multiple items in the Finder and open a single Info dialog for all of them by pressing the key combination option-command-I.
When you're done, turn TM back ON and close its preference pane.

Imac keeps crashing in time machine backup after upgrade to mountain lion

2008 imac kept crashing (shutdown and restart) during first backup after upgraded to mountain lion. The backup size was about 10GB but time machine crashed after a while (at most 2GB) and never completed backup. So, I don't have any backup since right before I upgraded from Lion. Any suggestion?

Something strange happened. I was able to get time machine to work by going out to the login screen (the account kept logged in) and let it run the backup with the screen off (screen auto off after a few min). I tried it on two different external drives and that did the trick on both. Since the initial Mountain Lion backup was huge (155 GB), I was quite surprise that it worked at all. I assume your MBP was a Lion to ML. I also just did a 2012 MBP upgrade but that one was smoother. I did not recall having crashing issue. One thing I did find during this was that my WD passport USB drive was corrupted. Not sure it was the cause or not. I had to erase and reformat to get it back to work. Maybe do a verify disk to confirm. Good luck.

New IMac is crashing randomly because of "Panic Kernel Error." Now IMac startup disk is not visible and will not mount. What the story with this machine. Running 10.6.7

Almost certainly, some sort of hardware problem on your logic board.
Make an appointment and take it to your local Apple Store: http://www.apple.com/retail/geniusbar/

My iMac just crashed, and I had some documents open in Pages that were unsaved. Is there a temporary file or backup file that I can access as on a PC? (I have just looked in Timemachine which I had operating, but it did not seem to have any temp files).

My iMac just crashed, and I had some documents open in Pages that were unsaved. Is there a temporary file or backup file that I can access as on a PC? (I have just looked in Timemachine which I had operating, but it did not seem to have any temp files in it at all - not sure what it would be useful for then).
Any suggestions?

Question asked and answered several times.
If you didn't save, nothing is recoverable.
iWork apps don't create temp files so, as far as you on't save something, Time Machine can't archive it.

My machine crashed on the first download with what appeared to be 90% done, now it is stuck "downloading Creative cloud desktop" at about 10% internet working fine.

My machine crashed at the first attempt to download, now the Adobe installer is stuck at 10% when trying to download Creative Cloud desktop. do I need to purge some files to get it going? iMac 10.6.8 Internet service is fine. Thanks.

Thomh57685518 I would strongly encourage you to run Mac OS 10.7 or later if possible. You can find the system requirements for the Creative Cloud applications at System requirements | Creative Cloud.

9.1.1 Time&Pitch Machine crash

Running L9.1.1 on an iMac Core Duo w/Snow Leopard 10.6.2. With or w/o plugins loaded, Time&Pitch Machine crashes out to desktop when entering numbers from either keypad or alphanumeric keys. Deleted all plists w/o change in crash behavior. Also no change after creating Empty Project w/single audio track, mono or stereo. Can't find any reports of this crash in other forums. Otherwise 9.1.1 is stable. Thanks for thoughts on this possible bug.

hmm I was fortunate not to have this in 8 or 9.0.2
but this is a definite/repeatable bug in 9.1.1 which causes crash
sample edit window
then select time and pitch or any Factory menu items
on exiting window or pressing screen set 1 key command crash happens evey time 1 track of audio no plugins
cannot work with 9.1.1 as a result
and you didnt fix screen set/display text only jumping window bug anyway, even when you said you had on release notes!!
come on apple

My home imac has crashed and will not boot up.

Hi
My home imac has crashed and will not boot up and I'm not sure where to start.
It wouldn't shut down properly so I turned off the power, and now it won't go beyond the apple logo and timeer when I try to restart it.
It is an imac (4 years old), Intel, running OS X, not sure which version, but probably the latest.
Thanks
Carol

I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Let us know if these two procedures don't solve the problems.
Hope this helps

Machine crashed while downloading Mavericks - how to restart?

In the middle of downloading Mavericks, my machine crashed (iMac 10.7.5). After restarting, Launchpad has an update bar underneith in in the toolbar, but there is no Maverick loader when I open Lauchpad. When I go into Appstore, there is no Maverick under purchases. When I type Maverick in to Spotlight, it isn't found. When I try to rerun in the AppStore, I have the "Free Upgrade" button. When I hit Free Upgrade, it changes to Install App, sometimes asking for my Apple Password (after reboot every time). But, it never starts a download, even after waiting for a hour or two.
How do I get unstuck? Is there a way to delete the crashed Maverick upgrade? Can I go back in time with my Timemachine backup? I know that restarting in the AppStore doesn't work.
Thank you for any help.

And what is wrong with Trend Micro Titanium as a package?

If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
   3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. Most of the real-world danger of malware attack comes from highly targeted "zero-day" exploits that are not yet recognized.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.
