  • 20 inch Aluminum iMac crashes after installing Mac OS X Combo Update 10.5.6

    I have a school lab with 22 of the new 20 inch Aluminum iMacs. They all have been having a problem with crashing after someone logs onto my network server, which is still running the 10.4 Tiger version of the Apple server. They run fine if you boot up and log on as a local user, and they seem to run fine when you boot up and log on to with a server account, but when you log off from the server, about five seconds later while the aurora screen is still showing, they crash and give you the Apple version of the "blue screen of death."
    I was told that the fix was to download the combo update separately from the Apple website and use that to reinstall and update the operating system.
    I downloaded and tried installing with a 10.5.6.dmg file and a 10.5.6.dmg.smi file, but they both crashed.
    Where can I find the "fixed" version of this update or is there some other fix?
    I have tested this on 9 or 10 different systems.
    The first file was MacOSXUpdCombo10.5.6.dmg, which is a disk image file that is 668.8 MB or 684,774 KB.
    I looked in the discussion groups on the Apple web site and found some discussions for problems that seemed similar to, but not quite the same as my own. They led me to a file MacOSXUpdCombo10.5.6.dmg.smi, which a self mounting image file that is also 668.8 MB. I tried it and got the same result.
    I can install my dvd, which gives me 10.5.1, which will log off and reboot correctly.
    I can then install several miscellaneous upgrades:
    Pro Apps Update 2006-02 V1.0
    AirPort Utility V5.3.2
    Remote Desktop Client V3.2.2
    QuickTime V7.6
    iTunes V8.0.2
    and also
    Front Row V2.1.6
    The system will then log onto the network, log off and reboot correctly.
    But, when I install the 10.5.6 combo update from any of my sources, it boots and logs on fine. But, if I log onto the network, it crashes when I log off.
    Where do I go from here?
    Thanks for your help.

    Have you tried starting up with your install disk and doing a disk repair?
    Put the install disk that came with the Mac in the DVD/CD drive and restart holding down the 'C' key. You can take your finger off once you hear it making noises from the DVD/CD drive. You'll be presented with a screen where you choose your language. At the next screen on the menu bar select Utilities>Disk Utility you then select your Macintosh HD on the left and click on 'repair disk'. If it makes any changes click on 'repair disk' again and repeat the process until you get a clean pass. Once done select restart from the Apple menu and hopefully the Mac will boot normally.

  • Problems with FileVault 2 on my iMac mid 2007 with Mac OS LION on it

    Hi guys !
    Get a problem with FileVault 2 on my iMac mid 2007 with MAC OS LION on it. FileVault 2 works, but after rebooting my system, it was unpossible to select an account with the cursor of my trackpad. No chance.
    Before activate Filevault 2 the trackpad works fine. No problems to select an account. Anybody else with the same problem ?
    Regards
    Volker

    Hi EVO67 !
    I checked out your solution, but.... sorry it doesn't works.
    So I cut off the bluetooth connection of the magic trackpad from my iMac and pair it again, but the problem is the same.
    May be it's bigger bug with LION, so I need an update for this function.
    But thank you very much for your help.
    Regards
    Volker

  • I have an iMac. , mid 2007.  Frequently, when I take an action, the little color wheel starts spinning and goes on for quite awhile.  Save a file, close a file, open a file, open a window, it's all random.  Somtimes it stalls, sometimes it doesn't.  Why?

    I have an iMac. , mid 2007.  Frequently, when I take an action, the little color wheel starts spinning and goes on for quite awhile.  Save a file, close a file, open a file, open a window, it's all random.  Somtimes it stalls, sometimes it doesn't.  Sometimes long, sometims short.  Why is this happening?

    Consider adding more memory. Be sure you have adequate free space on the hard drive - 15 GBs or 10% of the drive's capacity, whichever is greater. Do not run too many applications concurrently. Visit The XLab FAQs and read the FAQ on resolving the SBBOD.
    Do some maintenance:
    Repair the Hard Drive and Permissions
    Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Kappy's Personal Suggestions for OS X Maintenance
    For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utilities are: Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior.  Versions 1.5.1 and later are Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    SyncTwoFolders
    Synk Pro
    Synk Standard
    Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac Maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.

  • I have a rather old iMac 20" (mid 2007) and I want to upgrade the Hard drive. How do I change it? How do I transfer all my applications? May I just copy the old hd into the new one? Thanks.

    I have a rather old iMac 20" (mid 2007) and I want to upgrade the Hard drive. How do I change it? How do I transfer all my applications? May I just copy the old hd into the new one? Thanks.

    There are many online tutorials on how to change out the HD on a mid 2007 iMac. One of the originals is from 2007 and is Upgrade your iMac 20" or iMac 24" aluminum (mid 2007) to 1TB Hard Drive and 4 GB RAM - DIY Guide. As far as migrating your system Apple helps out with that in Setup Assistant which automatically starts when you turn on a new Mac for the first time. After you have installed the new HD you will have to format the new HD to Mac OS Extended (Journaled) and then you will have to install OS X. The first time you turn it on Setup Assistant will start. Follow the directions and you will be fine. In order to restore your information you will need to backup what is on the current internal HD first. I'd recommend using Time Machine (Assuming you are using Leopard or later) AND also creating a bootable clone using either SuperDuper or Carbon Copy Cloner.
    Please complete your profile so at the very least we know what version of OS X your machine has installed.

  • Replacing imac 24" mid 2007 hard drive

    hello everyone
    recently my imac 24" mid 2007 320gb 2gb ram mac hard drive completely failed i have tried everything it starts up sometimes then freezes other times it doesnt even recognise the hard drive so i am currently using it through a boot on a external hard drive my question is if i were to replace the hard drive myself (using youtube videos i am quite tech minded so looks fairly easy) would i have to get a certain type of hard drive i know its 3.5" but is there a simple to the size 1tb/2tb and als oi have read the transfer rate may need to be tapered down is that true and if so how would i go about doing it ?
    any help will be appreciated thanks very much

    http://img.tomshardware.com/us/2003/05/01/sata_hard_drive_with_a_kick/raptor-3.j pg shows an image of a hard drive with a jumper.   Reading from right to left, the first four prongs are power prongs.  Next you'll see a white plastic item covering two pins (that's known as a jumper).  On some SATA drives, they cover the prongs circled in red on this image:
    http://i16.photobucket.com/albums/b13/CRazY_GAmEr_07/SATA2.jpg
    Either style of pinout on SATA drive, if you don't have the jumpers covered by the right plastic item, it will not work backward compatible, or will confuse the computer as to what speed it actually is.  This is why you need to ask Western Digital if any jumper needs to be on the jumper pins of the drive in question to work as the master drive on your computer given your computer's data bandwidth for hard drives.

  • Why does safari crash after lion upgrade

    why does safari crash after lion upgrade

    Right or control click the Safari app in the Applications folder then click Get Info.
    In the Get Info panel, look for the Safari version number. If it's prior to Safari 6, updating to Safari 6 may help.
    Click here >  Safari Quits Every Time Opened: Apple Support Communities
    Then click the link posted by:  gregoryfromcork
    That will automatically download this file >  Safari6Lion.pkg.download
    Now quit Safari.
    Go to your Downloads folder and double click that file and follow the instructions for installing.
    Then restart your Mac, try Safari.
    If you already have Safari 6 installed, post a crash report.
    If Safari has just crashed, press the Report button on the CrashReporter dialog box to view the crash  information.
    Copy/paste the entire contents of the Crash Reporter window into your reply including the, "binary images" sesction.
    f the crash report dialog does not appear or the crash is hard to reproduce, crash logs can be retrieved from the ~/Library/Logs/CrashReporter> folder.

  • HT201210 I continue to get an error 37 message when trying to restore my iphone 3GS which crashed after trying to upload the last update. Does anyone else have this problem?

    I continue to get an error 37 message when trying to restore my iphone 3GS which crashed after trying to upload the last update. Does anyone else have this problem?

    Did you manage to fix the issue?
    I have exactly the same issue as described above : I installed the update 5.1.1 on my iphone 3GS and since then, I can not turn it on anymore. In Itunes, I get an error 37 when I am doing a restauration and it stops.
    This error has nothing to do with firewall : I tried to restore the phone on several computers, including in an Apple reseller and it did not work anywhere.
    I spent several hours on phone with the hotline from Apple which arrived to the conclusion that it is a hardware issue, but the phone was working perfectly fine until I installed this update!

  • Imac mid 2007 with mac ox lion reformat with what os

    hi i have a imac mid 2007 and i have with mac os x lion with it and i wanna reformat it because its so slow what os do i will install again?

    You may just need to reinstall, not reformat:
    Reinstalling Lion/Mountain Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • WiFi disaster after Lion 10.7.3 upgrade

    After Lion Desktop Combo Update 10.7.3 the WiFi Airport connection went down: an exclamation comma on the grey sign.
    No InterNet, no WiFi.
    After 3 foolish days of work, thanks also to this Forum tips&Trics, this is my walk-around:
    1. Lion 10.7.3 makes a seriuos jam of the WiFi Airport settings of your iMac, producing a devious IP address who excludes your computer from any connection: very, very skiddish, indeed;
    2. You must set MANUALLY your WiFi connection. Fro Your convenience I suggest to activate Airport Utillity 6.0 and after the System Settings, so You will be have a sound case-control of Your steps in real time;
    3. On TCP/Ip sectio: Set IPv4, set the mask AT THE ADDRESS OF THE MODEM, set IP address of the router.
    4. On DNS set the DNS address to that of the mai router.
    Apply.
    Turn Off the AIrport. Wait 10sec. Restar ARport and selection the right network.
    Take a look with the Airport Utility (we must wait patiently, if all goes well the lights will turn from orange to green in nearly 30sec).
    If all is gone well, You are on line anew.
    But, Apple Inc. all of this is very disappointing.
    Skiddish, very skiddish!

  • IMac 24" mid 2007 video card

    If my video card is bad will the mini dvi port work for an external monitor. My screens glows around the edges and flickers colors along edges also, no video at all. Thank you in advance.

    Kenand,
    Well you belong in the Intel forum but...
    If my video card is bad will the mini dvi port work for an external monitor.
    No
    My screens glows around the edges and flickers colors along edges also, no video at all.
    From the service manual:
    "1. Make sure all software updates have been applied to the computer. Refer to KBase article
    303903, Intel-based iMac: Installing available updates or to Apple Downloads “iMac Software Update 1.2 (Tiger) or iMac Software Update 1.3 (Leopard)."
    "Reset your computer’s PRAM (Parameter RAM):
    -- Shut down the computer.
    -- Locate the following keys on the keyboard: Command, Option, P, and R.
    -- Turn on the computer.
    -- Press and hold the Command-Option-P-R keys simultaneously. You must press this key combination before the gray screen appears.
    -- Hold the keys down until the computer restarts and you hear the startup sound for thesecond time.
    -- Release the keys"
    Reset the SMC:
    "To reset the SMC on an iMac (24-inch 2007)
    1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the
    power button for approximately ten seconds until it powers off).
    2. Unplug all cables from the computer, including the power cord.
    3. Wait at least 15 seconds. The SMC reset occurs automatically once the iMac has been
    unplugged from the AC power source for several seconds.
    4. Plug the power cord back in, making sure the power button is not being pressed at the time.
    5. Reconnect your keyboard and mouse to the computer.
    6. Press the power button on the back to start up your computer.
    Note: The iMac (24-inch) does not have a button on the main logic board for resetting the SMC,
    which eliminates the need to remove the computer’s cover to reset it (as required for some other
    models)."
    Report back. There are more tests but the front bezel and access door will have to come off.
