Why won't my old copy of a ML upgrade download work for my mac with SL?
I have tried asking this question in different ways and still do not know what to do. My situation is that I want to do a ML upgrade download from a copy I made in the past for use on SL. I have tried putting in a sudo date in Terminal from "install" to no avail. And don't know what else to do. I am not computer savvy. So is there an answer that I can easily understand or is this a wish that cannot come true?
Mac OS X (10.6.8)
