This final tutorial on setting up Fedora 24 in VirtualBox on Mac OSX will cover fixing the mouse wheel that Guest Additions reversed, adding a printer, installing codecs, and looking at other production software.

The Codecs are found here:

Note that my Mac OSX setup plays the audio, but not well.  This same setup on other virtual machines works fine.  The problem I was encountering in my test on this video is either due to the low system resources on my Mac or a problem with VirtualBox on Mac, which has been a known issue: Certain versions of VirtualBox do not connect to the audio devices properly.
