[VirtualBox]在MAC環境下的vm ubuntu裡面掛載共享資料夾

先安裝VirtualBox套件工具包

1. Update system's packages

$ sudo apt-get update 

2. install virtual box guest additions (referenced from here)

$ sudo apt-get install virtualbox-guest-additions-iso

3. Now install guest additional package (Crucial step! People generally miss this which creates an error “Unknown file type “vboxsf”)

$ apt-get install virtualbox-guest-utils

之後在VirtualBox主程式裡面設定掛載的資料夾名稱，設定->共用資料夾->加入新的共用資料夾。

現在就可以進行掛載，掛載語法為：

$ mount -t vboxsf shared /home/shared_folder;

How to install OS X Mavericks in Virtualbox with Niresh

We've previously shown you how to install OS X Mountain Lion on a virtual machine by using iAtkos ML2, which is great practice for installing Mac OS X on your actual computer. And now that Apple has released OS X Mavericks, it's only fitting that we show you how to install Mavericks in a virtual machine as well. Unlike in previous versions of this guide, we'll be using the newly-popular "Niresh" distro of Mavericks instead the old iAtkos distro (which is no longer publicly available for free). While we've already shown you how to install Mavericks on your actual computer with Niresh, it also works great with virtual machines.
