I'm trying to install Windows 10 x64 on my late-2013 13" Retina Macbook Pro but Boot Camp Assistant is refusing to create a bootable USB, citing that I need to have Windows 7 and above to do so. I can't figure out how to get around this, nor how everyone seems to have figured out how to natively install Windows 10 on their Mac. It won't even attempt the process for me. The W10 iso comes straight from Microsoft's website. Edit: Womp. Looks like the iso I downloaded got corrupted and re-downloading it solved my problem.
