I bought a SSD 60 gigs that arrives tomorrow. Since I use my computer to earn money like editing with Final Cut Pro 7 I intend not to update from 10.7, Everything works just fine. But when programming everything has to be the latest. I wanted Xcode 5 but it needed 10.8. So, I hope I have this right. 1. install new hard drive in empty slot. 2. install 10.7 OS 3. reboot with new drive and download 10.8 from the istore and install 4. download xCode 5 and install. Sound about right?
