Apple has released the new M1 Chip (ARM) equipped computers, which bring significant architecture changes (known as Apple Silicon). Among them, these devices will run (at minimum) macOS11  Big Sur, and handle tasks differently than previous Apple systems.

Those hardware and OS changes also modify how software works on these devices, which requires developers to transition their apps to “Universal versions”. 

Apple offers a way for users to run applications that are no native to M1 chips, by using their new translation feature called “Rosetta 2”.
