How to resize a VirtualBox .vmdk file on MacOS

I’ve allocated 30GB for the Windows 10 VirtualBox virtual machine. That amount of storage was short-lived, I installed Visual Studio and a few other development tools, soon,e I needed to expend/resize the hard disk storage.

I’m running Oracle VM VirtualBox Version 5.1.28, the syntax might change in different version of VirtualBox but the steps are the same:

  • Start a Terminal session. Terminal program is located in Applications -> Utilities -> Terminals
  • My Windows 10 virtual hard disk is in the .vmdk format so I need to convert it to .vdk format first, else I will receive an error like this:
Progress state: VBOX_E_FILE_ERROR

Virtualbox Virtual Machine Fullscreen

Virtualbox is Oracle‘s free Virtual Machine software. It’s fantastic, reliable and FREE! I’ve used it for a few years now and am loving it. I don’t install new virtual machines often but when I do, I struggle with the steps to enable the Virtual Machines to fullscreen mode. I’m writing this down now for future references.

The instuctions in the post assume that the virtual machine has been installed, for example, I would already done these tasks:

  1. donwloaded and installed the virtualbox software from Oracle
  2. downloaded and installed Windows 10 from Microsoft

Now, started the virtual machine and check if the virtual machine is shoing  a thick black frame around it when in fullscreen mode. It means that the virtual machine is not displaying the same size as the host machine when in fullscreen mode.

What needs to happen now is to download and install the “Oracle VM Virtual Machine Extension Pack”, then attached the Guest Addition (installed by installing the Extension Pack) as a CD image to the virtual machines so it can be installed locally on the virtual machines. Detailed steps are:

Veronika Decides to Die

 《韦罗妮卡决定去死》(Veronika Decides to Die)是巴西作家保洛·柯尔霍Paulo Coelho)的畅销小说之一,也是我看过的保洛·柯尔霍所著的第四本书。


我是保洛·柯尔霍的忠实读者却每次拿起了这本书又放了下去 – 我不喜欢看悲剧!一个好友前一阵和我谈到保洛·柯尔霍时推荐了这本书,还特地把书借给我。她说此书给她的人生带来了很大的影响,又特地解释,这不是一部悲剧。我在心里叹气,原来我和这本书这么有缘呢!老实说,看完以后,我发现保洛·柯尔霍的其它两本书,《炼金术士》(The Alchemist)和《少女布莱达灵修之旅》(Brida)在我心里的触动更多些。当然,一本好书在每一个读者的脑海里都会留下不同的烙印。



I know it is coming, and I do not fear it, because I believe there is nothing on the other side of death to fear. I hope to be spared as much pain as possible on the approach path. I was perfectly content before I was born, and I think of death as the same state. What I am grateful for is the gift of intelligence, and for life, love, wonder, and laughter. You can’t say it wasn’t interesting. My lifetime’s memories are what I have brought home from the trip. I will require them for eternity no more than that little souvenir of the Eiffel Tower I brought home from Paris.
