I installed 10.7.3 on my 27" iMac Desktop (about 2 months old) and restarted the machine. Now it loads the gray start-up sreen with the apple icon and a few seconds later a status bar appears below it for a couple of seconds. The status bar moves across a small fraction and then the computer reboots. The machine has done this every time and I cannot get it out of this boot loop cycle. I have tried pressing down shift on restart but this doesnt work - I presume the wireless keyboard doesnt register in time.

 

I am posting this from my laptop. I read online about "Target Disk Mode" and I am currently downloading the full update directly from apple (not using the software update). Please can someone help me. I don't want to do the wrong thing and mess anything up.

    There is yet another option.  When booting, hold down

    Command + R keys to boot into the Recovery HD.

    From here you can re-install OSX.  You will need a fast

    internet connection as it will download the latest and

    complete OSX and install it.  Doing this will just overwrite

    any old OSX stuff and applications should be intact.

     

    This would be a last resort option should the combo update

    not work in an attempt to save the current system.

    If Disk Utility can not repair your hard drive the chances are slim to none that it would be possible to install either the combo update or do a full Lion restore nor would the results of doing so likely be pleasant.

     

    There is also a possibility that your drive is failing. One of my Mac Mini's drives went south after only three months. Mac drives seldom die young but it does happen.

     

    Concentrate on getting your data completely backed up with two backups or more being wise. DiskWarrior can often repair drives that Disk Utility can't but it is very expensive and there are no guarantees it will work before purchasing it.

     

    In the future, make sure that you have at least two backups before updating. Running Time Machine in combination with making a clone on a separate drive is painless and pretty much assures that you will never lose more than an hour's worth of work.

  • porschee Calculating status...

    I found the following solution on an iMac of friends who just startet up to a first grey then blue screen with gear wheel and rebooted all the time.

     

    Restart iMac in "save Mode" (Hold shift Key at startup)

    log in and run software update from Apple Menu

    On this iMac the latest security and system update was available for installation

    Re-run this update

    Restart the iMac

    At this time the reboot run normal again.

     

    Side info: Before that I booted up from OSX Snow Leopard Disk and run Disk Utility with the result that the disk seemed to be o.k.!!

     

    Good luck !!!
