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. Here’s how to Install Guest Tool on 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. All of those are only possible with how to Install Guest Tool on macOS Catalina on VirtualBox.

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 improvment 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. In this post, I’ll show how to install Guest Tool on macOS Catalina on VirtualBox.

Guest Tool

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 see how to install Guest Tool on macOS Catalina on VirtualBox.

    YES, THERE’S NO AUDIO!
    I just installed the VM to test an audio related thing and it doesn’t work.

      no audio seems to be an issue with most people running macOS Sierra and later. Some users say they got audio(in) to work in a Catalina guest, when “passed” through a webcam. I assuming that at least some USB-attached audio devices would work in High Sierra & later guest VMs.

    To avoid the reboots, rename the ‘VMware Tools’ folder located under ‘/Library/Application Support/’. You can give it any name, and you will still benefit from the guest tool but won’t have the reboots.

      Better rename only the shitty script inside…
      sudo mv /Library/Application\ Support/VMware\ Tools/services.sh /Library/Application\ Support/VMware\ Tools/services.sh.old

      But I don’t see the point of installing VMware tools because VirtualBox tools are not working regardless of VMware being installed or not. So, no USB, no share, no 3D acceleration, everything is slow etc. You know already.

    The same issue for me – everything works well until 10 minutes (exactly 10 minutes) has passed, then OS is rebooted.

    Don’t install this. It will make your VM reboot for no reason ever few minutes. Wait for an update.

    Hi, I followed this tutorial to run it on VirtualBox and it works perfectly, since I can set the resolution to 1080p. However, there are 2 problems. The first one is that now Catalina reboots continuously after about 10 minutes after starting the virtual machine.The second is that when restarting the resolution is restored to 1024×748. Has it already happened to someone? Is there a solution?

    Hi,
    Works like a charm! Creating a few .command files makes it pretty easy to change the resolution from within the guest now. There is only one drawback: When starting the guest, it always defaults to 1024×768. Commands like
    VBoxManage setextradata “OS X Name” “VBoxInternal2/EfiGraphicsResolution” “1600×900”
    do only work during boot with VMSVGA as Graphics Controller. As soon as the GUI starts, it falls back to said 1024×768. Any idea/method to change that behavior?

    One other thing, that is probably related to the graphics driver: Apple Maps doesn’t seem to work (on Mojave). It only shows a black screen. Is that a known issue?

    Hi,

    I’ve tried the step to install the VMware tools 5 times and after restarting, my Display is always 3MB rather than 128MB (even though that’s what I configured in the VM itself).

    Any idea if I can try anything else from my end?

    Hi

    Thank you for this

    How would you make an iPhone recognised in the VM ? I can see it in the VM but it is not picked by the OS or XCode

    Thanks
