    Hi , I went and bought OSX Leopard recently

    I tried to load it on my Powerbook G4 15"

    any help would be much appreciated.


    From Mac support site
    Mac OS X 10.5: Unable to log in after an upgrade install
    If you perform a Mac OS X 10.5 upgrade installation from a version of Mac OS X that was previously migrated from Mac OS X 10.2.8 or earlier, you may not be able to log in to your user account if the password contains eight or more characters. This article applies to Mac OS X version 10.5 installation discs; this issue should not occur with installation discs that contain Mac OS X version 10.5.1 or later.

    If you are unable to log in
    you can use these steps instead:
    1. Restart in Single User mode (hold Command-S during startup). Note that single-user mode always uses the US English keyboard layout.
    2. At the prompt, type this followed by Return: mount -uw /
    3. Type this:
    launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
    1. Press Return
    2. Type this, then press Return: ls /Users
    3. Look at the listing and note the short name (username) of the affected user account.
    4. Type this: 

dscl . -delete /Users/username AuthenticationAuthority

Note: Replace "username" with the affected user account's short name you noted above.
    5. Press Return
    get this far and this comes up
    delete: Invalid Path
    <dscl_cmd> DS Error: -14009 (eDSUnknownNodeName)

    So obviously I cannot continue with the proceed your. If you have any advice or know what to do then please get in touch. As now the laptop is useless.

    6. Type this, followed by Return: passwd username

Note: Replace "username" with the affected user account's short name you noted above.
    7. At the "New password:" prompt, type the user's password, then Return. Note: It is recommended that the original user's password be used to match the keychain password.
    8. At the "Retype new password" prompt, type the same password, followed by Return.
    9. Type this, followed by Return: reboot

    Personally, I'd not load leopard on a G4 but rather go as high as tiger, which gives you the best performance and resource usage. 10.5 is a resource hog and will be slower on your G4 then the 10.4 will be.

    Put the disk in the drive, restart and hold down "c".

    Reformat, Install.

    Interesting. On the iBook G4 that my family had, we put 10.5 on it and it seemed to run faster than 10.4. On my PowerBook, 10.5 has performed quite decently as far as I can tell.
