I would like to install Windows 10 and use Bootcamp 6 to do so on a 2012 iMac. According to Apple's documentation, this should have appeared and been installed by software update. When I check my Bootcamp version though, it is 5.1.4. I have updated everything on the actual computer (10.10.5, etc).
They used to provide access to the direct PKG files to install, but I don't see one for bootcamp 6.
What am I doing wrong. According to their support document, this machine should be supported - https://support.apple.com/en-us/HT204990
