After over 2 years of using VirtualBox, I made the leap with Parallels and it is without regret. The integration with OSX is perfect, I can call my apps and Windows files with Spotlight seamlessly and I take my professional software (quotes, Dialux lighting calculations, tables with Legrand XLPro, rates suppliers ...) smoothly in parallel my Mac tools. IMPORTANT: THE KEYBOARD Mac is finally fully recognized in Windows, no longer need to juggle 2, 7 and other keys. Why did I wait so long?!? I am now planning to install an Android virtual machine to enjoy my favorite app unparalleled without leaving my phone.
