Back in 2011 I had bought an iMac that was delivered with OS X Lion. I don't have this Mac anymore, so sadly I can not create a bootable USB flash drive anymore. I had updated to Mavericks on that iMac (sold it this summer), but I guess if I had done an internet recovery or something like that, it would have installed the original OS of that computer, which would have been Lion. I never updated to Lion, but instead, like I said, it just came with the new Mac back then. So this means Lion isn't available in my App Store purchases either. What I have, however, is a Snow Leopard install disc. Is there a way to upgrade from Snow Leopard to Lion, and get Lion this way? I suppose not, right.
