Im running virtual box 4.3 on ubuntu 13.10, everything goes fine with windows guests but for Mac osx (Mountain Lyon) I just cant find how to install Guest additions. Seems like there's no osx installer in the iso. thanks in advance-

  • Since Apple only allows OS X to be legally installed on bare metal machines manufactured by Apple. There is no legitimate reason for a OS X Guest Additions. This is not related to Ubuntu. – user68186 Nov 8 '13 at 14:47

    I never said Im not using a machine manufactured by Apple. Isnt legal to install ubuntu on my MacBook Pro and vbox? – Nico Grunfeld Nov 8 '13 at 15:52

    I am not suggesting you are doing something illegal. I am just telling you why Oracle, the corporation responsible to VirtualBox will never produce such a guest addition. You could run Windows on Apple machine and run VirtualBox on top of Windows. I doubt you will be able to get OS X guest addition on VirtualBox running on Windows host. In the end, the issue is with Oracle and Apple, nothing to do with Ubuntu. See forums.virtualbox.org/viewtopic.php?f=22&t=31104 – user68186 Nov 8 '13 at 16:55

You're right, VirtualBox doesn't have guest additions for OSX. https://www.virtualbox.org/wiki/Guest_OSes

They only list Mac OSX Server (Leopard, Snow Leopard) under Mac and even that doesn't have guest additions.

It has something to do with licensing restrictions:

    @NicoGrunfeld An alternative (but hacky and slow) solution: You can use Google Drive or Dropbox to sync some files.. – numediaweb Jan 5 '17 at 13:39
