In my Apple ID I have Lion, Yosemite and El Capitan but no Mavericks. Mavericks is the one I want to install on my 2008 iMac but I can't just download it. I did purchase a USB thumb drive from Amazon with Mavericks on it but I really wish it was in my Apple ID so I can just download it when needed. Is there anyway to get it added? Anyone at Apple who can do not?
