Hi there, am a newbie here,

I searched the other threads here but didn't come across an answer that deals with my specific problem...I recently bought a new MacBookPro and used migration assistant to retrieve files etc from my old MacBook. This went fine but a prompt appeared informing me that the old one had the same name as my new one. Instead of just replacing my new one with the old profile I renamed it. This means that I have a bunch of separate folders for iPhoto and iTunes that i have to enter a password for to import them. It is just a mess and I would be happier to wipe it and start over. Looking at some forums it appears problems can start from here. If it is going to create problems would I just be better off cleaning up the hard drive as best I can? Or is there an easy way to reboot everything and start afresh?

    couldn't you just wipe and reinstall the OS?

    How do I do that? Do I just erase the drive in the disk utility, then just install the disks I got with it?

    Extended Hard Drive Preparation

    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)

    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.

    3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.

    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.

    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.

    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

    Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.


    After the hard drive has been reformatted quit DU and return to the installer. Complete your OS X installation. Once finished when you go through the Setup Assistant do not create a new account using the same username as the account you want to migrate. You may opt to use Migration Assistant then to migrate your Home folder from your other computer without running into any problem. Once finished log into your old account and delete the account you created during setup. All should be fine.
