I am replacing the hard drive (defective, but still works) on my 15" Macbook Pro, early 2011, running OSX 10.9 Mavericks. I bought an SDD from OWC and, following their recommendation, have installed the SDD on an external drive, plugged it into my computer, formatted it, and now wish to install a clean version of Mavericks on it. I believe this requires installing Snow Leopard (I have the disk) first and then installing Mavericks. I then plan to transfer data from the old hard drive using Migration Assistant. Unfortunately, I don't know how to install Snow Leopard onto the SDD. When I try, I get a message saying that I can't install it. Has anyone a solution?
It occurred to me that I might remove the old hard drive from the laptop and replace it with the formatted SDD, install Snow Leopard and Mavericks on the SDD, then install the old hard drive on the external drive and use Migration Assistant to transfer data from the old hard drive.
