Can I also have Snow Leopard boot external drive?
Can I also have Snow Leopard boot external drive? I have Macbook Pro with Snow Leopard and need Snow Leopard for several applications that will not run on higher systems. I Cloned snow leopard to external drive and boots fine. Can I also then install Mountain Lion on the internal drive and switch back and forth with no problems? Realize I will have duplicate Documents and Applications which I would have to keep organized.
