I have a 2014 MacBook Pro Retina that I purchased a few months ago. Is there a way to install OS X Snow Leopard on it? I do not have a DVD drive and do not own OS X Snow Leopard discs. I do have a retail copy .dmg file of it though. Can I copy it over to a USB flash drive and install it on a partition of my hard drive? How do I do that, if it's possible? Can you list the steps? I would appreciate it! Thanks! P.S. Please don't ask why.
