I can't download the BootCamp support drivers (OS X 10.11.2) I've got an Early 2015 MacBook Pro (128GB, MacbookPro12,1) and I'd like to run Windows 10 on it but as its own OS instead of via a virtualisation program. Due to the space constraints imposed by the 128GB flash drive, I've installed Windows 10 (using Rufus) as a Windows To Go installation on a 32GB Sandisk USB 3.0 stick I've got.

Windows 10 works perfectly normally from the stick (I boot into it via EFI) but I can't get the drivers for the hardware from Boot Camp. Whenever I run BootCamp on my Mac, it tells me I don't have the 50GB free on my boot disk that I need to be able to partition (I don't), but it won't go any further and give me the option to download only the drivers.

The only thing I want from Boot Camp Assistant are the drivers for Windows 10.

Is there a way to fix this? The Boot Camp 6 drivers (needed for Windows 10, apparently) don't appear to be anywhere online - I could only find version 5 on Apple's website, which I believe is only designed for Windows 8 (the setup program doesn't work on my MacBook when running Windows 10, anyway).

Any help is much appreciated, I'm rather noobish with all this stuff!

Cheers,
Dan
I'm on a Mid 2012 Macbook Pro w/ Retina and El Capitan 10.11.2.

I was able to do boot camp assistant > download drivers (no other options selected) Bootcamp would ask for a usb drive, ignore it and close the pop up. From here I took my mouse up to the menu bar, and did Action > Download Windows Support Software.

The first time I tried this I got the error "The Windows support software could not be saved to the selected drive. An error occured while saving the Windows support software".

The second time I tried it, a day later with a reboot, I tried it again and it worked. Not sure what made the difference. Finder might have not been running as I'm running a trial version of Path Finder.
