Hello all, I'm downloading a 4.34Gb file right now. I bought a macbook pro yesterday and so I'm getting the free upgrade. I suspect this is a full working InstallESD.dmg that may be bootable if I rip to DVD ( I don't have any 8 gig USB sticks to hand). I'm wanting to install this on a fresh blank SSD I just bought. Question is, do you think its doable or do I need to have 10.7.4 already installed on the SSD before hand? I don't have an enclosure for the SSD so the only means for me to install an OS on the SSD is from the DVD drive of the macbook pro. Kind regards!
