I bought a refurb macbook pro a few years back, to use for video editing. It came with Snow Leopard installed. I never upgraded beyond 10.6.8 as I still edit in FCP 7 and didn't want compatibility issues. Now I've reached the point where I need to upgrade my OS for pretty much everything other than video editing.
So I thought a good workaround might be to plug a microSD adapter into the SD slot, with a 128GB microSD card in it, and to install the OS 10.6.8 software on that. That way I could boot up from the SD drive when I need to do video editing, but the rest of the time I can just run the computer with the latest mac OS installed.
So here's my conundrum. When I bought the macbook pro as a refurb, it didn't come with software install disks. Is there a way to copy the 10.6.8 OS directly from my laptop to the microSD card? Or do I have to shell out the additional $ to buy another copy of 10.6.8 from the app store?
