Boot Camp Assistant hanging at “Downloading Windows support software”
I’m running Yosemite, 10.10.5 on an iMac (Retina 5K, 27-inch, Late 2014).
I downloaded the Windows 10 ISO file to a 16GB flash drive and attempted to install Boot Camp. Twice now I’ve had the same result: the Boot Camp Assistant runs for maybe 20 minutes, reformatting my USB drive and loading a bunch of files on it, and then hangs with my progress bar at 60% completion while stating: Downloading Windows support software, where it hangs (for a couple hours now).
