Bootcamp
i want to buy a new MacBook Pro 15 " but I can't because I need to install Windows 7 32 bit on boot camp. I can not use parallels because of virtual memory issues with a particular program. Any suggestions.
Buy a refurbished 2014 model from Apple listed at http://www.apple.com/shop/browse/home/specialdeals/mac/macbook_pro/15 (or look in your country-specific refurbished store). 2015 models no longer support W7. Anything older that Late 2013 models is not recommended. I personally prefer the nVidia GPUs over the AMD.
Please see the entire list in Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support.
