# How to Install VirtualBox in macOS Catalina Version 10.15.7

In order to explore [Parrot OS](https://www.parrotsec.org/) and [Kali Linux](https://www.kali.org/), I am looking into hypervisors to run the virtual machines. Oracle VM VirtualBox is free, open source and can be installed in macOS.

### Installation

1. Download [VirtualBox](https://www.virtualbox.org/)

2. Verify [SHA256 checksum](https://www.virtualbox.org/download/hashes/6.1.18/SHA256SUMS)
`shasum -a 256 <file-path>`

#### TIL

A Hypervisor is also called Virtual Machine Monitor (VMM). It creates and runs Virtual Machines (VM).
