partilhar entre OSX e Ubuntu com VirtualBox

• Com a máquina virtual desligada, selecione a máquina e vá em Settings > Shared Folders
• Adicione um new folder, em Folder Path coloque o caminho da pasta que está na máquina host. Em Folder Name dê um nome para a pasta
• Por exemplo "Share"
  
• Clique em OK e inicialize a máquina virtual
• No ubuntu, crie uma pasta para montar o share.
• Por exemplo "Share"
• Abra o terminal e digite "sudo mount -t vboxsf FolderName PathToMount"
• FolderName é o nome que foi escolhido para a pasta no segundo passo e PathToMount é o caminho do folder criado no ubuntu.
• Por exemplo: mount -t vboxsf Share /home/my_user_name_here/Share

Para não estar sempre a escrever o anterior:

• in Terminal: sudo gedit /etc/fstab
• add to the end of my fstab file
• "Share /home/my_user_name_here/Share vboxsf defaults 0 0"

In a Linux guest, use the following command:
mount -t vboxsf [-o OPTIONS] sharename mountpoint
Replace sharename with the share name specified with VBoxManage, and
mountpoint with the path where you want the share to be mounted (e.g.
/mnt/share). The usual mount rules apply, that is, create this directory first if
it does not exist yet.

Beyond the standard options supplied by the mount command, the following are
available:
iocharset CHARSET
to set the character set used for I/O operations (utf8 by default) and
convertcp CHARSET
to specify the character set used for the shared folder name (utf8 by default).
The generic mount options (documented in the mount manual page) apply also.
Especially useful are the options uid, gid and mode, as they allow access by
normal users (in read/write mode, depending on the settings) even if root has
mounted the filesystem.
