How to Install VirtualBox Guest Additions on MacOS Catalina

In this article, we will guide you through the process of installing VirtualBox Guest Additions on your Mac running macOS Catalina. This is a crucial step in setting up your virtual machine and sharing clipboard values between the host and guest.

Before we begin, make sure that your Gatekeeper settings are configured correctly. To do this, follow these steps:

* Go to System Preferences on your Mac Dock

* Look at Allow apps download from: and ensure it is set to Anywhere

Next, check if Gatekeeper is disabled. If you're not sure how to open apps from unidentified developers on your Mac in macOS Catalina, you can refer to our separate article for guidance.

If Gatekeeper is still enabled, you will need to disable it. To do this, enter the command `sudo spctl -master-disable` in the Terminal app.

Once you have disabled Gatekeeper, exit System Preferences and proceed with installing the Guest Additions package.

Note that installing the Guest Additions package on macOS 10.15 Catalina requires disabling multiple security features. This is because the OS now requires packages to be digitally signed, which cannot be completed as normal.

I was able to install Guest Additions using VirtualBox version 6.1.16 on Windows 7 and I believe this process should also apply to macOS 10.14. If you're having trouble installing Guest Additions on a different operating system, feel free to reach out and we'll do our best to assist you.

By following these steps, you should be able to successfully install VirtualBox Guest Additions on your Mac running macOS Catalina, allowing you to share clipboard values between the host and guest.
