Find supported macOS versions for your Amazon EC2 Mac Dedicated Host

You can view the latest macOS versions supported by your Amazon EC2 Mac Dedicated Host. With this functionality, you can validate whether your Dedicated Host can support instance launches with your preferred macOS versions.

Each macOS version requires a minimum firmware version on the underlying Apple Mac to successfully boot. The Apple Mac firmware version can become outdated if an allocated Mac Dedicated Host has remained idle for an extended period of time or if it has a long running instance on it.

To ensure supportability for the latest macOS versions, you can stop or terminate instances on your allocated Mac Dedicated Host. This triggers the host scrubbing workflow and updates the firmware on the underlying Apple Mac to support the latest macOS versions. A Dedicated Host with a long running instance will automatically be updated when you stop or terminate a running instance.

For more information about the scrubbing workflow, see Stop or terminate your Amazon EC2 Mac instance.

For more information about launching Mac instances, see Launch a Mac instance using the AWS Management Console or the AWS CLI.
