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.

So:

[unordered_list style=”green-dot”]

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.

Option 2

Another potential solution is to remove any RAM over 4GB run the install and then put the additional RAM back in after – even then try and limit the RAM slots to one, so not 2GB in each – rather 1 slot with 4GB.
