It was a long time coming but now available for download, macOS Big Sur is the newest and latest operating system for Macs. It marks a new era in Apple’s stage before the arrival of its own processors (Apple Silicon), the first being the M1 chip. If you are not one of the lucky ones to have a compatible Mac, here we tell you how to install macOS Big Sur step by step.

macOS Big Sur, an operating system with a redesign and benefits for the latest Macs

The news was interesting from a first glance, however, we knew that this system would not be for all Macs currently running macOS Catalina. Another situation that we did not expect is that Apple ventured to present Apple Silicon. At this time of November, users who have reserved their first Macs with the M1 chip are already enjoying the new features and benefits of macOS Big Sur.

On the other hand, older Macs that support the operating system have also suffered from problems. While it is true that each macOS transition is heavy and complicated, in macOS Big Sur it would be one of the most important in recent years. The transition from Intel to ARM will be one of the topics to be discussed during 2021.
