Parallells Desktop delivers a superior macOS virtualization experience to other solutions due to increased graphics performance, even with Apple limitations. However, smooth scrolling doesnt currently work in macOS unless you pass a trackpad or magic mouse through. It has an excellent feature set for both Windows and macOS, with the ability to auto install, and even detect events like Windows updates, the type of Wimdows installed, etc. Much attention to detail!
