Hey all, I have a circa 2006 macbook pro that originally came with 10.4. In 2007 I upgraded to 10.5 and I have just recently upgraded again to 10.6. My question is this: since 10.5 is no longer on my computer, could I legally use the 10.5 upgrade disk to upgrade another 10.4 machine? I know that the EULA only allows it to be on 1 machine at a time (unless you have a family pack), and this would be true in my case since the original machine that ran it is no longer on 10.5. Thanks!
