I have a Mac mini. I need to run the disk utility. The mini was bought with OS X 10.4 installed and come with a disk to upgrade to 10.5 which I did. I now need to run Disk Utlity but the original, 10.4, start-up disk asks me to decide if I wish to revert to 10.4 while the upgrade disk looks as though it is going to re-install 10.5.

How and where can I access Disk Utility?

Mac mini, Mac OS X (10.5.8)

    For disk repair, start from the upgrade install disk: don't start an install; from the Utilities menu choose Disk Utility.

    For Permissions repair it's better to use the Disk Utility in Applications/Utilities.

    Thanks but I am nervous about proceeding as, after the language choice, I am again asked if I want to archive or erase the installed OS. Choosing archiving then just offers me the possibility of installing! [I don't see any utilities menu]. Do I proceed or is the upgrade disk not the same as the original system diskette [which I also have]?

    What I described is apparently the usual behaviour but I don't have the Leopard upgrade disk so I can't advise (I'm sure someone else on here would know).

    if you really can't get it to work there is a method, though Apple advise that using Disk Utility is preferable: hold command-s while booting to get into single-user mode. Wait for all the scrolling text to stop and then type exactly this:

    fsck -fy

    noting the space before the hyphen: hit the return key. Don't get creative and type anything else: you can do a lot of damage that way.

    It will run a Disk Repair with the usual reports. If it says 'File system was modified' run it again. if it says 'The disk xxx appears to be OK' type

    exit

    to boot into the OS. But try to find Disk Utility on the install disk first, that would be preferable.

    Steps for using Disk Utility

    1. Insert your Mac OS X Install DVD, 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. 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.
    If you repair errors run it until no errors found.

    I'm sorry but, if you read carefully what I have written, things are not quite so straightforward!

    I want assurance that by proceeding beyond the choice of archiving installed version before installing, I will be given the choice to use the disk utility. The original install disks are for 10.4 - that also asks me about archiving rather than erasing. The OS X 10.5 disk is an UPGRADE disk and may not be the same as an install disk.
