The downloader downloads both Mac and Windows setup programs, which are both very small (< 3MB) and a lot of generic binary files.
Are these binary files cross platform? Can I use my Mac and the Mac downloader to get the setup files, and then install on my Windows PC?
I understand the need for two "installers" from the battle.net website as the downloading process needs to be platform dependant, but if the downloader downloads both .app and .exe files then it seems to be cross platform from then on.
Can anyone confirm this?
