My host machine is Windows 7. I installed Snow Leopard on VirtualBox but i am having problem installing the guest additions. The guest additions iso is mounted in /Volumes/VBOXADDITIONS_4. But if I run the install command sudo sh ./VBoxLinuxAdditons.run I get Unable to determaine library path.

Is installing guest additions for Mac OS X on VirtualBox even possible?

  • The only version of Snow Leopard licensed to virtualise on any host is the server version. That & all versions from Lion upwards are licensed for virtualisation on Apple hardware only. No other usage is permitted by Apple's EULA.

  • A workaround would be to create a *.iso and insert that. There might be some way to create *.isofiles on windows like on mac. I have compiled the (mac-)information in an answer here.

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.
