Just done a fresh install of Mavericks GM on my Mac Mini, the Mac Mini has an 128gb SSD + 500gb HDD. My setup has always been OS X on the SSD and Data/Downloads on the HDD. When I ran the Mavericks Installer it came up with a message saying something along the lines of my Fusion Drive setup was incorrect do you want to re-create it. I couldn't test to see if this would work as I had data on the 500gb HD I wanted to keep. So my question is....would the installer actually create a Fusion Drive for me even though the SSD is not from Apple (OCZ Branded) or would it of realised further down the line then failed?
