Hi all, I've been trying to install Windows 7 on my iMac so I can get a Visual Studio running quicker than on my Windows laptop. I opened up Boot Camp Assistant and selected both options to download the required Boot Camp files (for mouse/keyboard etc) and to install Windows 7. The first download bar only ever gets to around the 50% mark and then doesn't move any further. Are there any problems with it that I should be aware of? Is it trying to download a huge file? iMac is 2011 model, downloading onto a portable hard drive as it says to do.
