Sep 12, 2015 6:39 AM in response to BloodSukkaby Loner T,1. Was this done using a Wireless Connection?
2. Which country are you located in?
On a 2012 MBP, it takes 45 minutes to use a DVD (or an ISO - which is faster) to build a bootable USB drive. The actual support software is cached in
/Library/Application\ Support/Bootcamp/WindowsSupport.dmg and can be re-used as long as you do not exit the Bootcamp session. If you do, it will be overwritten to avoid stale drive packages.

Sep 13, 2015 7:39 AM in response to Loner Tby BloodSukka,Im in Australia, and Ive tried doing it via LAN. I couldn't imagine connecting via W-LAN, as opposed to Wired LAN, would cause this process to take over 8 hours. Boot camp is 600MB... that's all that is being downloaded over the air, as the Win Install media is local on the device.
It appears it is due to the side of the "sources\install.wim" Windows Image file, that contains the Windows pre-staged OS. Because MAC totally screws around with the install media, it has to mount the install.wim, make a copy of the WIM, then compile a new image file.

Sep 13, 2015 7:50 AM in response to BloodSukkaby Loner T,BC Drivers are unrelated and have no relationship to the install.wim file. The install.wim resides on the Windows ISO, the BC drivers package is the only download that BCA will run. It will take the BC drivers and the ISO, Copy the ISO in its entirety and create $WinPEDriver$ from BC drivers and the Bootcamp folder. There is no change made to content copied from the ISO.
As a test, can you download brigadier from https://github.com/timsutton/brigadier and run a test. This script directly talks to Apple CDN. You can see my example for using the tool at Re: Problem with Bootcamp .
