Hi ,
I would like to assist your with this .

Please can reply and provide me full details of the computer , OSX version , Mac model number , part number , age , any additional extras like memory that was installed and the screen size of the imac or laptop if possible.

I need to know exactly what Mac you are using , also are you under warranty?

-

It seems you haven't formatted your new HD drive ready for the install ?

If its an intel Mac please format using GUID tables and Mac OSX extended (journaled)

If its an older PPC Mac please use , Apple partition map and Mac OSX extended (journaled)

Please use Disk Utility to erase and format your New Mac HD disk .
Boot the OSX install DVD and choose Disk Utility from the Menu.

-

Once completed Install OSX to the new target volume Mac HD ,
again choose from the Menu to run the OSX installer.

Using the Mac OSX install disk , we can use the install option to install a new copy of the OSX OS to the Mac HD .

Procedure:

Please try to perform the install of OSX .

As follows :-

1 we need to boot from the DVD holding the C key on start up using a USB keyboard.

1 Boot up in to the OSX installer .

2 Before starting the installation, you may wish to use Disk Utility to verify and repair the volume, Select Disk Utilities from the Menu .
Choose to repair the Mac HD volume and then also repair disk permissions from within "Disk utilities" application and also erase and format your Mac HD disk if needed.

3 After using Disk Utilities , Choose Install Mac OSX or OSX Installer from the Menu.
to reopen the OSX 10.5 installer .

4 Select your language. The Welcome to the Mac OS X Installer window appears.

5 Click Continue.
The Important Information window appears.
After reading or printing the information, click Continue.
The Software License Agreement window appears.

6 After reading or printing the information, click Continue.
An agreement sheet appears. If you agree with the license agreement,
click Agree.

7 The Select a Destination window appears.
Click the HD volume that you wish to install to.
Choose your Mac HD boot volume .

8 Click Options.
The installation options sheet appears.

9 Select Install.

11 Click OK.

12 Click Continue to begin the installation.

Wait for the installation to complete and restart the computer .
Hopefully the installer will complete successfully.

Please let me know and if all is ok.

Update the system software using Software update , or preferably the OSX combo updater DMG downloaded from the Apple downloads section on apple.com .




Please let me know once you have performed the "install" to your new Mac HD .

I await your reply ,

Thanks .

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
