Hi Everyone. I have a MacBook Pro (2013-2014 model) and looking at installing parallels so I can run windows on my Mac. I am unsure if I should install windows 7, 8, or 10 would be super grateful for help please. I plan to run: 1. Storyline 360 (It says minimum requirements include Windows 7 SP1, Windows 8 or Windows 10) . 2. A windows application made by a company that is quite light on performance and works with computers as old as windows 7. The main thing is I thought the older the Windows, the better the performance, so if my main goal is everything runs fast, would it make sense to install Windows 7 SP1? I do not do any video editing or gaming. Also wondering how each option would affect disk space. Thanks so much everyone.
