I'm using virtual for running the virtual machines of this course LFS201. I'm running on a MAC (yosemite 10.10.5).
I have problems installing the virtual box additions "insert guest additions CD image..." option in the menu.
I got a message "unable to access VBOXADDITONS_5.0.22" and I can't mount the file nor can't create shared folder or drag and drop files to the virtual machines.
Could you please help me how to overcome this issue?
Thanks in advanced for your help!
