DevOps Pre-Requisite course - Lab setup: VM installation on Mac air M3

Hello everyone,

I am currently on the final module of a prerequisite Cloud Engineering course, and I have encountered several issues between the course content and real-world practice.

May I ask what prevents the content from being updated? Today is 22 January 2026, and I believe this course was recorded in late 2019 or early 2020.

My second question concerns tooling: how should I install and connect to Oracle VirtualBox Manager for CentOS 7 (1908, 64-bit) on a MacBook Air M3?

Thank you in advance for your time and assistance.
