Amazon EC2 M1 Mac instances now support in-place operating system updates

Starting today, customers can update Apple macOS operating system from within the guest environment on their Amazon Elastic Compute Cloud (EC2) M1 Mac instances. With this capability, customers can now update their guest environments to a specific or latest macOS (non-beta) version without having to tear down their existing macOS environments, launch new instances, and reinstall libraries, tooling, and dependencies such as Apple Xcode.
