My Windows 10 Pro is a new DVD version that I converted to an ISO file via the OSX disk utility, selecting the DVD Master mode, and then changing the suffix on the file from 'cdr' to 'iso'. The drivers download in the normal manner, and boot camp partitions the ssd as directed. When I initiate Bootcamp assistant it seems to work fine. I have two programs that must use Windows and require communication protocols such that they cannot function under Parallels or VMWare Fusion.
I have a new MacBook Pro 2018, I9, 32Gb RAM, 2Tb SSD, running MacOS High Sierra 10.13.6 with the Supplemental update installed, and am unable to install Windows 10 using bootcamp.
