Macbook does not start anymore after upgrade to Snow Leopard

I successfully upgraded my MacbookAir to Snow Leopard, but my son's Macbook refuses to start after having been upgraded.
Please help!

Hello,
my MacBook Pro (late 2008 unibody) just needs a main logicboard replacement, fortunatly still within warrenty, after updating to 10.6.0. I experienced the following: With an update from 10.5.6 to 10.5.7 the MBP freezed within 10min. after reboot, with every restart it freezed after a shorter period and finally freezed during the boot process. I've mounted the MBP as an external HD to my iMac, did an backup and deleted the internal MBP harddrive by overwriting it with zeros. I did the usual procedure of resetting SMC, P/V-RAM and reinstalled 10.5.6 - everything was fine again!
When Snow Leopard came out, I updated again, hoping the issue has been repaired. BUT I experienced the same problems and with some system permission deleting I got SL running as long as I did not turn on AirPort. As soon airport is activated and an internet connection is established I could count the seconds until the mac freezes. And it will only come up again by deleting the system configuration preferences (via single user mode booting).
Thereafter I was sure there is a hardware problem with the airport card or the logic board. The Apple Service Provider did not find any hardware failure and finally will change the logic board. Hopefully I got the Mac back next Tuesday. I let you know about the results.
Best regards!
PS: Obviously software could damage hardware or some hardware components used by Apple are not compatible with some of their software.

  • Itunes does not start anymore after upgrade to 6.05.20

    I upgraded itunes to the current version and after that itunes does not start anymore. I scanned for virus with an up-to-date scanner, scanned for adware with Windows defender and ewido and used the tips from http://docs.info.apple.com/article.html?artnum=42963
    I run itunes on Windows Server 2003 which worked fine for three years. I know it is officially supported on XP only.
    I deinstalled itunes and reinstalled afterwards no change. The windows event log shows some erors
    Faulting application iTunes.exe, version 6.0.5.20, faulting module shell32.dll, version 6.0.3790.2662, fault address 0x0015af84.
    Any other idea?
    Thanks
    Christoph

    ok, so I am not sure if this is legal or not, but there is a site called oldversion. Go there, and you can get past versions of applications such as aim , and in this case, itunes. just uninstall your other itunes first.
    Sometimes different versions of appications run better on different computers. this new itunes probably just has something the last one didnt that cant run with what you have on your computer

  • Time Capsule backup not working anymore after upgrade to Snow Leopard

    Hi,
    after I upgraded to Snow Leopard I started the backup process with the time capsule. Within several days I tried this about 5 times and the iMac crashed or froze after some time doing the backup - but it never completed.
    I then deleted the whole content of the time capsule and started a fresh backup. Now I receive a message after some gigabyte that there was a problem and I should try it again. Again the backup has not finished so far. I tried to reduce the amount of files to backup by excluding folders - no chance. Since the upgrade to snow I was not able to complete one single backup.
    Any ideas or similar experience?

    I have had a similar problem. I have the latest 1TB Time Capsule and backup worked fine in Leopard. I am backing up over my home wireless network. The backup starts, but at some point it freezes with the spinning pizza wheel if I click on anything. Everything freezes with no possibility of force quitting any application.
    I tried trashing the plist for Time Machine, but that didn't work. Tonight I'm going to try a backup with the computer connected to the Time Capsule by Ethernet.
    I can access my existing Time Machine backups on the Time Capsule.
    This is a frustrating situation. But for this, SL works great, but this problem is a critical one.

  • IPhone 4s does not trust iMac after upgrade to Snow Leopard. I am using my iPhone's hot spot for internet connection.

    Can't sync iPhone and iMac since upgrading to Snow Leopard. Using iPhone for internet access. Help??

    Hello Brad:
    First, forget about a virus. There are NO documented viruses that affect a Mac running OS X - none.
    Do you have about 10-15% of the HD free at all times?
    Open activity monitor and see what is taking the processor capacity.

  • HT1688 My iphone 5 does not ring anymore after upgrading to ios 7.0.2

    My iphone 5 does not ring anymore after upgrading to ios 7.0.2.  It did not happen right away, but maybe 2 weeks ago.  I tried turning the "do not disturb" on and add allow everyone to call as well as turning it off but it only vibrates when calls come in.  I also turned my phone off and it still only vibrates when calls and messages come in.

    I found another feed and said there is a silent button next to volume bar.  That was the problem.

  • IPhoto does not start up after upgrading

    On my new iMac iPhoto does not start up after migrating. Upgrade from iPhoto 6/Snow Leopard > Lion 10.7.1 with iPhoto 9.1.5. When the conversion is finished I can see the new library, it works allright. And with packet-inspection (or how is that called in English) all maps & data seems to be OK; I can check the seperate pics.
    But: iPhoto won't start up a second time (grey screen with infinite spinning wait cursor). The same thing is happening when I add a new library and drop in some pictures.
    What can cause this problem?

    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

  • Isight is not working anymore after updating to snow leopard

    it used to work very well. i updated snow leopard 5 days ago. i try to use skype and photo booth, it is never working again. do people have the same problem?
    thank you for your information

    Thanks for the info - however surely this has something to do with the snow leopard software update - not a hardware failure or is that just a coincidence?
    My iSight was working fine before I upgraded to snow leopard? Is there a software fix coming?
    Welcome to Discussions, lightwright
    ... this has something to do with the snow leopard software update ...
    You may be correct that the problem has something to do with your SL update, but, as previously explained, many of us successfully use iSight every day after upgrading to Snow Leopard, so the problem is not SL itself. If you believe that your problem is with your update, you should consider reapplying the update using the method suggested above.
    If you continue to have iSight problems after properly applying the SL update, consider all relevant troubleshooting suggestions in http://support.apple.com/kb/HT2090
    However, if your iSight problem continues, and if iSight now does NOT show as a USB device in your Mac's System Profiler, yours is most likely a hardware problem. In that case, contact Apple or an Apple-Authorized Service Provider for service.
    If, after properly applying the SL update and using the Troubleshooting suggestions, iSight IS recognized in System Profiler but still does NOT work with any of your video-enabled Apple software, your disk may contain some pre-SL software that is causing problems. Either erase the disk and apply only Apple software to see if that fixes your problem, or seek help from your Apple-Authorized Service Provider.
    ... Is there a software fix coming?

  • Transport service does not start automatically after upgrade to exchange 2010 SP2 from Exchange 2010 SP1

    Hi,
    I am trying to upgrade Exchange 2010 SP2 from SP1, but Transport service does not start automatically.
    Tried manually start services, it started successfully but again goes down within few seconds automatically.
    Reboot server. but no luck.
    Any help.

    Hi,
    I recommend you use event viewer to check if there are any relate event logs. This may help us to find the cause.
    In addition, as Amit mentioned, Exchange 2010 SP2 isn't supported by Microsoft, I think upgrading to SP3 is a much more sensible approach.
    Thanks.

  • Macbook keeps shutting itself off after upgrading to snow leopard

    Hi everyone, I hope you can help me out as I am out of ideas! After be assured that I could upgrade my late 2006 intel based macbook (10.5.8) to snow leopard, I bought the disc and tried to install. Everytime I tried, it shut itself down. I wiped the hard drive clean and tried again. Still happened. Finally after 14 hours of attempts, something finally stuck and I had snow leopard. I then tried to get all the updates and it kept shutting down. I tried to migrate my files from time machine and it shut itself down. Fed up, I tried to go back to leopard, but the computer won't stay on long enough to complete this. I wiped the hard drive clean again and now it won't stay on long enough to get to the start up page! HELP! I tried starting up in safe mode and it won't work. I've run disc utility several times and it says everything is OK. Now I have a blank hard drive on a computer that won't stay on for more than 5 minutes. Any insight would be greatly appreciated, otherwise I got to take it in to an apple specialist as the apple store has already told me the refuse to work on it because it is older than 5 years!!!!

    Try a PRAM reset
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound two more times.
    Release the keys.

  • BExAnalyzer.exe does not work anymore after upgrade to FEP 3

    Dear all,
    after installing FEP 3 I noticed the following behaviour:
    If I try to run the new Bex Analzer from the Menue (Start -> Programs -> Business Explorer -> Analyzer) nothing happens at all. Neither Excel does start, nor the Analyzer plugin is loaded at all. A start from C:\Program Files\SAP\Buiness Explorer\BI\BExAnalyzer.exe) does as well not work.
    But running the Excel macro directly from C:\Program Files\Common Files\SAP Shared\BW\BExAnalyzer.xla starts Excel and the plugin is working as expected.
    So the question is: is it a bug or a feature?
    Best regards,
    Andreas

    I checked all components of the installation and everything seems to be ok. The only thing that I fell over is the statement
    "Ensure that the BExAnalyzer Application has authority to create dll's in the user's temp folder"
    Do I really have to take care of this? How? (I already disabled the virus scanner, but the result is the same - it's not working)...
    Thanks,
    Andreas
    PS: Can someone tell me in more detail, what the BExAnalyzer.exe is trying to do?

  • HT204210 My Photostream in iPhoto 9.6 does not sync anymore after upgrade to MacOS 10.10.2

    My Photostream is perfectly synchronised in all my iOS devices and at www.me.com.
    But in iPhoto (and Aperture) it went wrong (no synchronising after jan 26th).
    Could it be that Apple is more strict in Apple ID?
    E.g. originally I registered my name + mail-address (Bill Wye [email protected]).
    In the last years Apple added me.com and iCloud.com.
    According to me.com my AppleID is Bill Wye [email protected]
    According to my iOS devices my AppleID is Bill Wye [email protected]
    According to my Mac my AppleID is Bill Wye [email protected] (In my Mac I can't change the mail-address of my Apple ID)
    Or do you think Apple isn't strict at mail-address in Apple ID, and is it another little defect file somewhere in some applicationlibrary?

    that is three different Apple IDs - log all devices into the same Apple ID

  • I have a big problem with Lion and PGP. After upgrading from snow leopard to lion I cannot access my PGP drive which was generated under snow leopard. PGP does not start but gives a notion that lion cannot work with my PGP version. Solution?

    After upgrading from Snow Leopard to Lion I cannot access a PGP drive which was generated under snow leopard. PGP does not start. When I try to start I just receive a message that Lion cannot work with PGP. How can I now access important and confifential informatio which I have stored in PGP (snow leopard). Do I have to move back to snow leopard. If so, how can I do this? 

    If you have this product,

    you have to go back to Snow Leopard.
    To re-install SL, back up your home directory, format and re-install.
