10.6.8 update makes imac continually reboot, 10.6.8 update makes imac continually reboot

I had Snow Leopard installed on my iMac and all software updates were current. 10.6.8 was installed and everything was ok. It started randomly freezing a few weeks ago (I think it was actually after I did the last software update but I can't confirm), so I went to BB and bought a family pack install disc for Snow Leopard figuring I could reinstall to hopefully stop the random freezes as well as update my MacBook from Leopard to Snow Leopard to get it ready for Lion.
I upgraded the macbook with no issues, and then ran the check for software updates and installed the update to 10.6.8. Everything runs fine.
The iMac, however, was a different issue. Once I installed the OS from the disc, everything was fine, and basing this on very limited use, the random freezing had even stopped. But once I let it install the update to 10.6.8 the computer just repeatedly rebooted itself. It goes as far as the background loading, desktop items becoming visible, and the top menu bar and the dock loads...then the turning gear starts reboots until it gets to this point again. I have tried doing the whole thing over but get the same result. I have also only did the update on OS, unchecking the other updates it wants to perform, to try and narrow it down..but same result. Thanks in advance for any ideas and help.

When an update goes haywire using the Combo installer is often the solution. In fact I have software updater configured to just notify me when an update is available and I download the Combo updater from the get go. It is a larger update but I figure it is safer - plus with 3 different computer models in the household it means one download rather than 3 different downloads.

Problems with Mini--continued reboot after update

I recently was given a Mini to play with. I was having some issues with it when I first received it. I read some forum posts and some other non-apple related help files on the internet. I finally got the Mini to work correctly, at least I was able to get to the menu screen and get the Mini recognized by my computer. When iTunes recognized my new ipod I was told to update the software, I did. The update that was "needed" was 1.4.1. I went ahead and downloaded this update. I was then told to plug the Mini into the wall outlet to make the update complete. I did this as well. I left the Mini plugged into the wall, using the Apple AC adapter and the provided USB connector. The Mini flashed the apple icon then the "plug into the wall" icon. I left the Mini plugged in overnight, I had no idea how long it would take to finish the update. The next day I tried to plug the Mini into my computer and I got a message telling me that my ipod might be corrupt and I should reset the ipod back to original settings. I tried that.
Now, as I type this, I have the same Mini plugged into my computer and it does not register as a USB device on my computer and itunes does not even recognize that it is connected. The Mini seems to be caught in some kind of rebooting loop. The screen continually reboots, going from the apple icon to the "plug in" icon. I don't know what else to try, besides throwing the ipod away.
I would really like some help with this problem. I have tried the 5Rs and I have gotten nowhere. I will gladly take any suggestion that can be made.
I am running a Dell Inspiron with Windows Vista Basic, if that helps. Thank you for any help.

I have followed your intruction and it does not correct the problem. Diskmode does not appear. The ipod is completely locked out. The apple symbol appears, followed by the plug-in picture and that is all.
This is a result of an update to version 1.4.1 via iTunes. Surely Apple have to provide a fix for this error as it was no fault of anyone elses that these ipods are now rendered useless.
To make matters worse, I have all my uni assessment information on the ipod, which is my sister's, and I can no longer access it. My assessment is in 2 days.
If I have to get the ipod "repaired" due to an apple update then that is plain ridiculous. To cost me money for repair due to an update provided by apple? That's insane. Apple should take responsibility for the problems this update has caused and provide a fix.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

IMac reboots when attempting to update OS X 10.8.2

Hello,
I have a mid 2010 iMac 27"
I am running OS X 10.8.2
I have a notification that an update is available and a restart is required. When I click to do this the iMac reboots and then starts to install the update. After a little while the iMac reboots and I get the grey screen and then the message which says my iMac has been restarted because of a problem. I can then log in as normal.
This also occurs when Office 2011 attempts to install a software update.
Anyone got any idea's? I am trying to avoid reinstalling my OS

Try installing 10.8.3 through the Combo edition > http://support.apple.com/kb/DL1640 After installing it, install the Office update.
If you continue getting kernel panics, the next start you should see a window telling you that your computer turned off because of a problem, so press "Report" and copy here what you see in the white box

Chronosync (http://www.econtechnologies.com/pages/cs/chrono_overview.html)
and
Dropbox (https://www.dropbox.com/)
Both work very well. The former I use for manual, one-way synchroniziation of (nearly) entire systems. The latter for automatic syncing of very active directories through local and shared online storage.

TS3274 iPad 2 Auto-rebooting continuously after OS update to iOS 7

My iPad 2 is auto-rebooting continuously after OS update to iOS 7 . After every reboot , it is waking up for around 20 seconds and then rebooting again with apple logo coming on the black screen . I tried switch-off/on but the problem is still there . Please tell what to do .
PS : The iOS update was completed successfully . The General>Software-Updates shows "up to date iOS 7" .

I somehow managed to restore the ipad within 20 seconds time . I erased all settings and data by General>Reset>Erase-All-Settings-And-Data (simply reset settings did not work) . Make sure you have backup of your data (on iCloud or iTunes) before doing the previous step . Thank god , now it is working fine . *** Apple !!

After installing the latest updates, my iMac will constantly crash and reboot.

After installing the latest updates for Mac OS X yesterday, my iMac constantly crashes and reboots. It will only boot properly in safe mode. Even when starting with command+R for recovery the kernel crashes. I have had this iMac for about 3 years and never had an issue until last night, when this problem started and it seems to have gotten worse over night. I already tried the <option><command><R><P>, but it seems that that made it worse as well.

Trying running this program and then copy and paste the output in a reply. Please use copy and paste as screen shots can be hard to read.

Hello all.   Hope someone can help me. I recently downloaded some updates for my imac. Since doing this the computer starts up but I get no logon box. The home screen opens but I can't open any programs or files. I've tried rebooting, no joy. Help!!

Hello all..   I hope someone here can help. I recently downloaded some updates to my imac. Since then the computer starts but I get the home screen opening without the logon box.    I can't open any programs or files and if I click on the Safari tab it disappears from the dock. I've tried rebooting with no joy.
I contacted technical help at Apple and was told to hold down the ctrl and alt keys with two other keys, I think the S or P keys when powering up. This worked
and the computer seemed fine but now the problem has reappeared. Is there a way to removed downloaded updates from the computer or revert it to an earlier state?   Sorry for the long question. Hopefully one of you clever people can help.   Simon

Hay thank you for your time . I do that every time I know I am online. It says that I am up to date . I have found that I have 10.4.11 version, and that my boot version is 10.6.2, and that my kernel version is 8.11.1.
I have a hard drive icon on my desktop that says 10.6.2....
I use to have iphoto, it doesnt open anymore, it says there is 1.2gigs on that disk.There are many things on here that are the same way. Where do I start?
It's always good to go with one thing at a time and stay focused on that. Let's start with the OS you're running. Click on the Apple menu > About This Mac. What does it say under Mac OS X version ?

I used to be able to make iDVDs to share. photos with family members. Now I can't even open iPhoto when I am working on iDVD. I have a 2008 iMac. I already recently updated the computer memory from 1GB to 4GB.

I have not been able to make any iDVDs lately. I can't open iPhoto to access media when I am in iPhoto. I presently am trying? Recently I updated the memory on my 2008 iMac from 1GB to 4GB, but this did not help. I just reinstalled iLife 2009. Can anyone help me?

IMac G5 (no iSight) random yet continuous reboots

Hello,
I've purchased in 2005 the new iMac G5 through the Apple Store.
At first everything was doing great. I was using it only for my personal usage, since I had been given a PC laptop for work.
I started using it less & less (no time, too much work) until about a couple of years ago.
But, since then, I've noticed it has a wierd behavior: it keeps rebooting (sometimes during startup, sometimes just after the desktop appears, sometimes 5 to 20mn later - there's no rule).
It just seems to reboot less often once it is warmed up...
It might be linked to the repair extension campaing that Apple set up but also closed in 2008.
I am surprised I have never been warned nor contacted by Apple despite purchasing the iMac directly from them and, furthermore, along with an AppleCare 3 years contract...
Could someone let me know if:
1) this problem could be linked to this known problem (so far, I've read that the main consequence of the power supply problem was that the iMac wouldn't start up at all);
2) if there's a way I could still get the iMac repaired through this repair program although it is now closed
TIA,
Manu

Hi Manu - I'm afraid the repair program ended years ago.
Try resetting the SMU:
   1. Shut down the computer.
   2. Unplug the computer's power cord.
   3. Press and hold the power button for 5 seconds.
   4. Release the power button.
   5. Attach the computers power cable.
   6. Press the power button to turn on the computer.
Then open the back of the Mac and check the caps (little soda cans) to see if they are leaking or if their tops are not perfectly flat.
Let us know how you make out,
Miriam

IPad 2 was updated to latest iOS 7 and has been not working right since. I have tried to do a restore but still continues to go into reboot mode by itself and very erratic. Can no longer trust it. I tried to complain to Apple but have to give them 20 buck

iPad has not worked right since it updated to latest software. Tried to question Apple about it but it costs 20 bucks just to lodge a complaint. Is this normal Apple behavior or am I missing something. Also anyone else having issues with upgrade to iOS7. It was working great until that point and now goes into reboot mode often and sometimes will continuously reboot several times. I have tried to restore but that didn't clear the problem. Any thoughts or help would be appreciated.

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

You need to restore the iPad.
Use iTunes to restore your iOS device to factory settings - Apple Support
If that will not work, you will need to use Recovery Mode to restore.

Have CS 5 Installed on my iMac and works ok. But installed on my new MacBook Pro it won't open NEF files from my Nikon D810. Displays NEF icons, but when I try and open them the response is: Make sure latest RAW updates are installed. If problem persists

Have CS 5 Installed on my iMac and works ok. But installed on my new MacBook Pro it won't open NEF files from my Nikon D810. Displays NEF icons, but when I try and open them the response is: Make sure latest RAW updates are installed. If problem persists follow link: http://www.adobe.com/go/kb407111. Have installed Bridge 5.0.2.4; Raw Ref Version 7.0.0.308; DNG converter_8_7_1.dmg; Bridge 5.0.2 Update 2. Also same problem with Lightroom which I don't normally use. Lightroom_3_LS11_mac_3_6.dmg installed.

In the link you posted it states that the Nikon 810 requires ACR 8.6 or newer.
Version of ACR are specific to versions of Photoshop. You cannot use 8.6 nor even 7.0.in CS5.
I believe that ACR 6.7 is the latest that will work with CS5, so make sure you have this installed and get rid of ACR 7.
Having 2 versions of ACR will cause problems.
You have already downloaded DNG Converter 8.7.1.
Have you double clicked the DMG file to allow you to install DNG Converter on your computer?
Be aware that DNG converter is a stand-along application and not a plug-in.
You need to open DNG converter at select the FOLDER that contain your .NEF files.
Don't open the folder and try to select individual files, it doesn't work that way.
After converting your D810 files to DNGs you can then open the DNGs in CS5
The problem is your camera didn't exist when CS5 & its version of ACR was developed.
i don't use Lightroom, but the list mentions Lightroom 5.6 as needed to open D819 so your 3.6 version of LR won't cut it.

I've update iOS devices to 8.0 and now need to update xCode, but keep getting "unknown error -50" leaving me with a non-working internet connection - the only fix seems to be reboot of both iMac and router - any ideas?

Having updated all my iOS devices to iOS 8.0 I now need to update xCode to match. I've tried several times, and on each occasion have received an "unknown error -50" message after getting about 500Mb. After this my internet connection appears to be fully occupied, and the only fix appears to be a reboot of both the iMac (2.5GHx Core i5, 4Gb RAMm OS X 10.9.5) and the router (Netgear DG834 v5, firmware 1.6.01.34) At first I thought that the error had not stopped the download, but after waiting for 30 minutes the connection was still unresponsive, though traffic was indicated as passing through but the router status page, and no additional content had been added to the download. Anyone else having a similar problem and different ideas as to fixing it?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
