I have been having two different issues related to the performance of my virtual machines running on my brand new MacBook Pro (15-inch, 2018). Given the specifications of my new Mac, there shouldn't be any issues running a simple Ubuntu 16.04 LTS instance.

The Specifications of my Host device:

  • 2.9GHz Intel Core i9, 6 core processor
  • 32 GB of 2400 MHz DDR4 RAM
  • Radeon Pro 560X 4096 MB, Intel UHD Graphics 630 1536 MB
  • Mac OS Mojave 10.14

The Specifications of my Ubuntu 16.04 LTS Guest:

  • 8 GB of RAM
  • 2 CPU Cores
  • 16MB of VRAM
  • Virtualbox Guest Additions installed
  • Virtualbox Extension Pack installed


However, when I boot my Ubuntu instance I get the following two bugs.

  1. "Enabling 3D Acceleration" causes the screen to detach (See the following image).

    Steps to reproduce:

    1. Install an Ubuntu 16.04 LTS guest on a Mac host.

    2. Enabling 3D Acceleration in Settings > Display > Screen.

    3. Boot the Linux guest.


  1. If "3D Acceleration" is not enabled, the Linux Guest is graphically laggy.
