Like GhostBSD guests on VMWare it's also easy to enable smooth mouse, clipboard sharing, and auto-resize for TrueOS. Only one tiny adjustment is required. Keep in mind though that TrueOS is still in beta and is tracking FreeBSD 12-CURRENT as of this writing, so things might be a little unstable. By 'unstable' I mean that updates might break stuff, the OS itself works pretty well with VMWare.
