How to Install macOS High Sierra on VirtualBox

In this article, we will guide you through the process of installing macOS High Sierra on VirtualBox, a popular virtualization software that allows you to run multiple operating systems on your computer. By following these steps, you'll be able to install and run macOS High Sierra as a guest OS on your VirtualBox host machine.

Prerequisites

Before we begin, make sure you have the necessary requirements installed on your host machine. You will need to have VirtualBox installed on your Mac running macOS High Sierra, and you should also have a copy of the VirtualBox Guest Additions ISO file.

Step 1: Enable Shared Folder Access

To access shared folders between your host machine and guest OS, you'll need to enable shared folder access. To do this, run the following command in the terminal:

`sudo usermod -aG vboxsf USERNAME`

Replace `USERNAME` with the username of your guest OS.

Step 2: Install Guest Additions

Next, install the Guest Additions on your VirtualBox machine. To do this, navigate to the 'Devices' menu and select 'Optical Drives' > 'Choose disk image...'. Then, select the VBoxGuestAdditions.iso file located at `/Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso`.

Step 3: Add Shared Folder

To add a shared folder for Ubuntu on your macOS High Sierra host machine, follow these steps:

1. While the VM is running, go to the 'Devices' menu and select 'Optical Drives' > 'Choose disk image...'.

2. Add your folder and select 'Yes' for 'Auto-mount'.

Step 4: Install VirtualBox

To install VirtualBox on your macOS High Sierra host machine, follow these steps:

1. Run the VirtualBox installer just like any other installer.

2. Go to System Preferences > Security & Privacy.

Troubleshooting

If you encounter issues during installation, such as a 'System software from developer, 'Oracle, America, Inc.' was blocked from loading' error message, you'll need to allow the installation to proceed. To do this:

1. Click on the lock in the bottom left corner of the window and enter your password.

2. Click 'Allow' next to the 'blocked from loading' message.

Additionally, if you encounter a prompt about not allowing unsecure system extensions, you can click 'Next' for now.

By following these steps, you should be able to successfully install macOS High Sierra on VirtualBox and set up shared folders between your host machine and guest OS. If you have any issues or need further assistance, please let us know in the comments below.
