installers no longer are working

[pcpete]

So I have some patch tools that allow me to DL the latest 4 OSes from Apple directly, how do you get hold of older versions ?
Currently would be needing Mavericks, El Capitan and Yosemite. (don't think there is any need for earlier than that is there ?)

Some clients need older versions to run legacy programs like the older versions of the Adobe suite which clients own and have already paid for.
