How to Install Guest Tool on macOS Catalina on VirtualBox

With the macOS Catalina recently out, it’s a nice opportunity to check out those features by installing it. While installing or upgrading from the previous version is simple especially on Apple computers. Often users would like to try these features on Windows, which isn’t that hard as well. On Windows, they would have some options to take, which we did talk that there were no more than three ways to try macOS on Windows. Of those methods, one of them is pretty awesome plus quite interesting to experiment with. That is installing macOS Catalina on VirtualBox.

Without a penny charging, VirtualBox is a superb virtual machine app that runs most of the operating systems including macOS Catalina. It provides almost all the features that are required to run and work on a virtual machine. With all these things, macOS Catalina installed on VirtualBox lacks some features that we’ve fixed some of them such as macOS Catalina screen resolution, speed up slow running macOS Catalina.

That done, there are still some qualities that it lacks. These are, CPU support, GPU support, speed improvements and more. These features are definitely an improvement or even required for most users that will do the work seamlessly. To diagnose and troubleshoot all these struggles, the Guest Tool is the perfect tool for this. With the new version of VirtualBox particularly VirtualBox 6 out, it supports Guest Tool plus a new VMSVGA option that improves the overall performance of a virtual machine.

Just like VMware Tools on VMware, it is a pack of useful tools and utilities which enhance all aspects of a virtual machine. As a result, it will improve the performance of running a virtual machine on VirtualBox that will cover all the operations and tasks. In specific, it improves most of the aspects such as mouse and keyboard performance, GPU tasks and operations, display and screen resolution up to 16:9, more CPU support, quick operations and a lot more. In this post, we’ll install Guest Tool on macOS Catalina on VirtualBox.
