I was able to Install Guest Additions with no problems on the same iMac and VirtualBox with Fedora 18.

This short video shows you how to add VirtualBox Guest Additions to your virtual machines to add. If you are using VM Virtalbox Version 6.0.0 (Qt5.6.2) or later select Optical Drives (for older versions its called ‘CD/DVD Devices‘) uncheck VBoxGuestAdditions.iso 3. Without restart, click on “ Devices ” again and ‘ Install Guest Additions ‘. Finally, I figured it out. I can not mount Guesteditions.iso file in Tails OS. Because Tails OS loads from ISO image or USB stick and wipes it's data after every restart (literally wipes all data). If you unmount Tails OS iso file then virtual machine no longer works. – user3252885 Mar 28 '17 at 15:48.
