If that still doesn’t get rid of the message I have found on a device that the drive needed to be reformatted – the only thing different about the drive I was trying to install to was that it had a Boot Camp partition on it The Boot Camp partition might be a red herring but certainly reformatting the disk solved the issue.

  • clone the main HD drive to an external disk use CCC – link below
  • boot from the external
  • erase/reformat the main HD – use HFS Extended Journaled
  • clone back the main HD from the external
  • reboot from the main drive
  • run the installation upgrade again

This time – no problems.

If you don’t care whats on the disk just erase it and run the upgrade, I wanted to keep all the data intact in my example, hence the clone back.

Cloning courtesy of the fantastic bombastic CCC.
