Hi can you help.


I have an Imac 1st Gen which had 10.5.8 OS installed. Have tried to re install back with the 2 disc's which came with it and Apple have confirmed they are the correct disc's Tiger 10.4.8. As this unit was given needs to be formatted. Have tried most things and every time I restart get the”This software cannot be installed"


Have formatted and now to a point that if I start normally I get a flashing folder. The unit was working fine until I played.

    Make sure you are using DVD #1.


    If you have back ups have you considered wiping your comp of everything & starting from scratch?  Not sure what you have already tried as you did not provide any details.

    Have tried most things



    Clicky click--—> Erasing disks securely




    Start up from your install disc, go to Disk Utility and select the disk and click erase - to securely erase data click Security Options and Erase Free Space which will entirely wipe your disk, overwriting it with zeros so that no data is recoverable.

    So it will not boot from the Install Disc, or it does?


      1. Insert the Mac OS X 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 Erase 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. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion do a new install.
