Hi, personally i’m using a MacBook with VirtualBox of Window 10. I have allocated 100GB storage size for my VirtualBox. Even though I can see Virtual Size is 100GB and Actual Size is 18.56GB and it has a maximum of 20GB but somehow i can’t use the Virtual Size. VirtualBox download: Desktop 20.04 download: to create an Ubuntu Virtual Machine on y. I'm happily using VirtualBox on a MacBook Pro with Retina display. However, ever since the release of VirtualBox 4.2 moving windows in a guest OS is very slow, i.e. The movement of the window is considerably lagging behind the pointer movement up to a degree where it gets unusable. Copy this over to where your Virtualbox is setup. The Mac is no longer needed at this point. 🛠️ Setting up Virtualbox. ⚠️ Before continuing, install the Virtualbox Extension Pack, if you haven’t already. This comes with a special USB 3 driver that without, the Mac simply won’t see USB devices.

Step 1： Download the Sierra installer from Mac App Store.

This should be done in you Mac and the installer will be placed in /Application/ folder.

Step 2: Prepare Sierra iso

Use geerlingguy’s script to prepare a sierra iso file.

Step3: Install VirtualBox in Ubuntu

You should have your VirtualBox and the Extension Pack installed, or use my ansible role

Step 4: Open VirtualBox and create a new VM.

Settings:

• name: your_sierra_vm_name
• type: Osx
• version: Mac OS X 10.11 El Capitan (64-bit)
• Other

Step5: Configure VM for MacOS (Very important!)

Run following commands and replace “Sierra” with ‘your_sierra_vm_name’.

Step 6: Install Sierra

Insert sierra.iso to the sierra VM’s optical driver, and follow the instruction to install Sierra.

Note: In the installer, Go to Utilities > Disk Utility. Select the VirtualBox disk and choose Erase to format it as a Mac OS Extended (Journaled) drive.

Step 7: Remove sierra.iso and restart VM.

Ubuntu or other Linux distributions may be slow when you run it within VirtualBox. Often, the cause is that not enough RAM is assigned to the virtual machine, which makes it run slow and makes it unresponsive. However, if your VM already has plenty of RAM and you also already tried assigning an extra virtual CPU core to the machine, this guide might help you make Ubuntu faster in Oracle VM VirtualBox.

Execute the following command to see if 3D acceleration is being used or not:

It will probably say:

Now that’s bad news, because the graphical interface of Ubuntu makes your whole system slow and laggy. So first of all, make sure you have the VirtualBox Guest additions installed.
Once this is installed, we now install the vboxvideo driver:

Mac Os With Virtualbox

Now, shutdown Ubuntu. Then, you open the settings of your virtual Ubuntu and you go to ‘Display‘. Now tick ‘Enable 3D Acceleration‘.

Start your (formerly) slow Ubuntu and you should notice faster navigation, opening of apps as well as an overall snappier experience!

If you really want to speed things up even further, you can install the CompizConfig Settings Manager. To install and run it, open Terminal and execute this command:
