Install the VirtualBox Guest Additions
In order to be get the complete functionality of VirtualBox such as resizing and sharing of folders, you’ll have to add the Expension Pack.
1. Start your Ubuntu VM
If your Ubuntu is not already started up go to your VirtualBox menu, select the created VM and press “start” and wait until you see the Ubuntu Desktop screen.
2. Add the Guest Edition
Click the “Devices”-tab of your VirtualBox window and select the “Insert Guest Additions CD image” option (Sorry, can’t provide a Screen Shot). On Mac it’s located in the top menu bar of the Ubuntu VM window.
This should automatically download the needed files into your Ubuntu. You may have to confirm the download and type in your password to proceed.
If everything worked as planned you should now be able to resize the window to adjust the size.
For further information on how to start/stop the VM, increase font size and other features see the Frequently Asked Questions section.
Next, install the tools and packages needed for the tutorial.
