VirtualBox has a major advantage when compared to VMware Fusion: it’s free software and so anyone with a bit of time and computer knowledge will be able to run a wide variety of guest operating systems on their Mac. It includes lots of customization options, too, which do admittedly require the user’s attention and a little bit of tech knowledge to make the proper selection.
VMware Fusion, on the other hand, counterbalances the cost of the license with the wide variety of automated features it packs. Deploying a new virtual machine is less time consuming and requires less user input, while the bidirectional sharing and Unity mode just work. This makes VMware Fusion the convenient choice for those who want things to be as smooth and simple as possible.
