KHunziker Level 1 Level 1 (0 points)
I was on my iMac when it started to suddenly take 3-4 minutes to load a program, then an additional 3-4 minutes to do a single change, being frustrated, I did a hard shutdown of the iMac. Now it will not boot. I looked in some threads and I tried booting into safe mode, but it didn't load, then I did CMD V and I get one of two errors so far. They are:

.Loading kernel cache file 'System\Library\Caches\com.apple.kernelcaches\kernelcache.1913ACA7'
Couldn't get file info.
Loading 'mach_kernel'
Could not open file 'mach_kernel'
Error loading kernel 'mach_kernel' (0xa)

the other one gets past this part and stops at:

AppleYukon2: RxRingSize <= 1024, TxRingSize 256, RXMAXLE 1024, TXMAXLE 768, STMAXLE 3328

I do not know what I did, can anyone please help me?

iMac (Mid 2007), Mac OS X (10.4.10)

    Hi KHunziker, and a warm welcome to the forums!

    Very Important, how much Free Space is on your Hard Drive first of all?

    Could be many things, we should start with this...

    "Try Disk Utility

    1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."

    http://docs.info.apple.com/article.html?artnum=106214

    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

    The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions. (Well, the Installer actually uses superuser Permissions to do it's work, but after reboot it doesn't guarantee communication with other existing needed files Permissions.)

    Some people get away without Repairing Permissions for years, some for only days.

    If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!

    If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.

    May even need to do an Archive and Install if you have room on the HD, but saves all your files and gives a new OS...

    http://docs.info.apple.com/article.html?artnum=107120

    I only use Software Update to see what is needed, then get them for real via...

    http://www.apple.com/support/downloads/

    That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing.

    If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

    http://docs.info.apple.com/article.html?artnum=107120

    Just be sure to select Preserve Users & Settings.

    Unfortunately, I travel between two locations, my mac is in one location and all the software is in the other. I am going back this weekend, so I will look for the software when I get there, but I make no guarantees.

    I did try booting into safe mode, it did its little loading thing for a little while, i got that grey screen with the apple logo, then it rebooted itself, but still got stuck at the same points.

    I should have plenty of space on my HD, I have a 500GB, shouldn't be that full. I also have a 1TB external that I use for storage and archives.

    Thanks for the help!
  • KHunziker Level 1 Level 1 (0 points)
    So I borrowed my father-in-law's 10.5.1 utility disc and got to the first aid part, I selected my 465.8 GB WD5000AAKS-40YGA0 drive volume (the only other volume is the Pioneer DVD-RW drive) and the button for Repair disc is greyed out. Do I need my 10.4 utility disc?
  • BDAqua Level 10 Level 10 (119,685 points)
    Hmmm, seems like you weren't actually booted from the 10.5.1 Install Disc, did you boot up holding the c key or Option/alt key down?

    Likely won't work if it's a Gray Machine Specific Disc though.
  • KHunziker Level 1 Level 1 (0 points)
    i held down the c key for a while, then let go and waited... it booted to the mouse setup, then went to the star field and asked what language i wanted to use.
  • BDAqua Level 10 Level 10 (119,685 points)
    Select the Language, then go no further, look for the Menubar up top for Utilities>Disk Utility.
  • KHunziker Level 1 Level 1 (0 points)
    well, now my HD doesnt appear on the Disc utility. only my DVD-RW
  • KHunziker Level 1 Level 1 (0 points)
    Alright, now my HD is back and I am in the Disc Utility, what next?

    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk."

    Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
  • BDAqua Level 10 Level 10 (119,685 points)
    Well, not the Tiger Install Disc, but the Leopard one you're booting from.
  • KHunziker Level 1 Level 1 (0 points)
    it does not appear that I have a disclosure triangle. I was able to click on the information button and this is part of what it says:

    Partition Map Scheme: GUID Partition Table
    Mac OS 9 Drivers Installed: No
    S.M.A.R.T. Status: Not Supported
    Disk Number: 0
    Partition Number: 0

    it does not appear that I have any partitions or volumes.
  • BDAqua Level 10 Level 10 (119,685 points)
    OK, forget the disclosre triangle.
    S.M.A.R.T. Status: Not Supported


    Is this the Internal HD for sure... Something is very wrong if that's the case!?

    Does it show Macintosh HD or what exactly?
  • KHunziker Level 1 Level 1 (0 points)
    all it says is 465.8 GB WDC WD5000AAKS-40YGA0 Media

    that's all it says for my HD
  • KHunziker Level 1 Level 1 (0 points)
    I assume that if I try and set up a partition and what not that it will format the HD and erase my info? is it better if I just get a new HD installed? i already have an enclosure for a SATA drive, would I be able to retrieve the info from it if I get the HD replaced and use it as an external?
