In macOS High Sierra, the VMware 7.x no longer supported so I have to use Virtual Box 5.2 to use Windows. Since this laptop comes with Windows 8.1, therefore it has a product ID which I extracted from RWEverything since it didn’t come with the DVD. The Virtual Box 5.2 works perfectly with macOS High Sierra and it’s free. I’m not going to use Windows 8.1 often, just for some Windows programs, so I don’t really need all the bells and whistles Virtual Box. If you don’t have Windows Product ID#, you can download Windows 10 for free to use, just can’t activate it for some custom settings.
