I don't want to install Mavericks onto a Windows PC – I want to to download the installer (5Gb) onto a Windows PC and then install it on a Mac from a USB drive.
For reasons I won't go into, it's not practical to download the installer directly to the Macbook, but I can download it at another location where we only have Windows PCs
(and a more generous data allocation). I want to then copy it to a USB drive and install it on the Mac. Possible?
