Why AWS is bringing Apple’s MacOS to its cloud
Developers writing software for billions of Apple products need to test that software on Apple hardware, and now they can run those tests on AWS.

Given that Apple doesn't license its operating system to companies to install on their own hardware, the Mac Mini has been the cheapest option for a long time. AWS will likely add Mac Minis based on Apple's M1 chip at a later date.
