Im attempting to install Snow Leopard on my mac and at about the time the install says "46 minutes ramaining" the install then says "install will finish after your computer restarts". My copmputer restarts an nothing happens. Nothing is installed or anything. I have tried booting the copmputer with the disk but that didnt work either.

iMac, Mac OS X (10.5.8)

    You also posted about this in a similar post in these discussions



    but there you also indicated that there was a problem with the install DVD. That it needed to be cleaned or that there was an error reading from the DVD.


    It sounds like you might have a problematic install DVD. Where did you get it from?

    Hard to tell what happened without more info from you. What happens when your computer starts up now? Does it boot into something? Is it 10.6, or 10.5? Look at About This Mac (under the Apple menu), what does it say under Mac OS X, does it say "10.6.3" or "10.5.8" or something else? Click once on that version number, it will report back a build number, what is that build number?


    Try booting from the install DVD for 10.6 and instead of installing, run Disk Utility from that install DVD. Tell it to Repair the Macintosh HD. Does it find anything to fix or repair? When in Disk Utility, look at the bottom of the page, does it say S.M.A.R.T. "verified"? If it says anygting other than verified, the disk may be failing.


    How old is your iMac? Does it meet the requirements for 10.6? I'd suggest at least two or three times the disk space requirement shown below, by the way, for a normal installation.


    System Requirements:

    Mac computer with an Intel processor

    1GB of memory

    5GB of available disk space

    DVD drive for installation


    Finally, do you have a backup of all your files? If so, and none of the above provides any insight, I'd use the 10.6 DVD to erase the disk and install a fresh system, and then restore the user files from the backup. A good way to do that is via Setup Assistant, which is what runs on the first reboot after such an erase and install.

    What steve626 has suggested makes good sense.  The only curiosity lies in your thoughts that the machine is about 3 years old.   I think the last machines supplied with 10.5.(x) Leopard were sold Mid to end of 2007.   That makes your machine at least 5 years old.


    That leads to the question of whether or not it is an Intel based machine because if it isn't that would explain the problems you have.


    Sorry to intrude, Steve,

    My computer just boots normally as it did. It is in version 10.5.8. The build is 9L31a. It says that I have an invalid volume directory count and filesystem verify or repair failed when I attempt to verify my hard drive. My mac is probably around three years old. It does meet the requirements for 10.6. I would not be a problem to start with a fresh system as I do not have much on the computer.

    The invalid directory count and file system errors need to be fixed before the operating system installation can proceed. The new operating system install copies in more than 200,000 new files and with the invalid directory errors, this will get worse.


    When looking at "About This Mac," what is the Processor identified as? It should say "Intel something ..."


    Click on your Macintosh HD and under the File Menu, select Get Info. How much disk space have you used and how much is available?


    Anyway, assuming you have an Intel processor and plenty of disk space, the next step would be to boot from the 10.5 Install DVD OR from the 10.6 install DVD, and run Disk Utility from that DVD. Select Repair Disk (not Verify Disk) from the options shown on the buttons in Disk Utility. By the way, I suggest that you copy important files off this disk to a backup before doing this repair, just in case something is really wrong with the hard drive and it actually fails, or in case a reformat is needed.


    If the Disk Utility indicates that it fixed something, run it again until it reports back that the disk is ok. If it reports back that it is unable to repair the problem that it found, that's another issue that can be dealt with with other tools.


    If this were my computer, I would also test the memory, as a bad memory chip can cause such file system errors. The Apple Hardware Test (that came originally with your computer on the accompanying DVDs) will check memory, but it isn't as good a test as MemTest

    Has your computer been freezing much lately, or having other problems?


    In any case, you should not proceed with the 10.6 upgrade until the file system errors are fixed.

    To REPAIR the disk (as opposed to just VERIFY) you need to boot from the OS Install DVD, like you did when installing 10.6, except this time you DON'T  proceed with the install by clicking "Continue," but instead from one of the menus at the top of the screen called "Installer", select an option in it for Disk Utility. Choose that Disk Utility option, do not click Continue as that would continue with the Installer, which you don't want this time.


    If you are having trouble booting from the DVD (it sounds like you are), note that this should work from either the 10.5 or the 10.6 install DVD. In any case, if you insert the DVD, then click restart, holding down the C key (it takes several minutes so be patient) should boot up from the DVD. If you have trouble with that, hold down the option key and then select the DVD to boot from when it gives you choices of boot disks.


    Once booted from the DVD, select Disk Utility from the Installer Menu on the first screen and then select REPAIR for your hard drive.
