Share folder in VirtualBox Host=Mac OS, Guest=Debian

Found my answer

Assumption: "VirtualShare" is the shared folder name set up via Devices | shared folders ... menu

sudo mkdir /mnt/MyShare
sudo mount -t vboxsf VirtualShare /mnt/MyShare

AH! Now I can see the files in /mnt/MyShare/VirtualShare/

• the mounting :( does not survive a restart/reboot

This answer is bewildering because the VirtualBox documentation explicitly states that auto mounting is done in /media directory. And indeed, the shared folder is created - but its empty.

Further, I did/do not understand the significance of /mnt directory. That looked arbitrary to me, but apparently not. ../MyShare piece of it is; use any name you wish.

Now if I could only delete all those folders I created during experimentation. And to think I used to be an absolute wiz on the CP/M command line! (that sure dates me!!)

From Virtualbox Manual : Chapter 14:

14.2. Known Issues
Mac OS X guests:
VirtualBox does not provide Guest Additions for Mac OS X at this time

What you are trying to run is the script for Linux distributions. That does not work on OS X due to numerous differences in the system, despite a similar-ish base.

From the content of this, I wouldn't hold out for such support in VirtualBox any time soon.
