I've read Parallel's responses to people asking about Parallels 10 on 10.11 and that it's not officially supported. What I want to know is how well this setup has worked for users who have actually tried this setup. Please, no theories nor conjecture based on what the company has said, I'm looking for actual experience from actual users using this actual setup. In particular I am looking at running Windows 10 or Windows 8 with 3D games using Parallels 10 on El Capitan.
