How to upgrade Mac OS version on mac1.metal instance?

0

Hello!

We have a mac1.metal instance working for deployment and it was created a few years ago with Catalina AMI (amzn-ec2-macos-10.15.7-20201204-234310). We use this instance to build iOS/Android Apps successfully until Apple changed the minimum SDK for a build to iOS 15 that requires Xcode 13 so we need to upgrade the OS to the last version.

I made a snapshot of the current instance and then I tried to upgrade it but when the machine restarted I got stuck there because I think it requires physical access to confirm the OS installation so I rollbacked the instance with the snapshot I previously created.

It is possible to upgrade the instance without losing any data/configuration? I searched on the AWS documentation but I didn't see how to upgrade the OS.

Thank you!

These steps should help update the OS, but most use our vended AMIs for the new OS for IaC and automation purposes. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-mac-instances.html#mac-instance-updates

  • Hello SeanM! Thanks for the reply. Yes, I see that on the documentation and I tried to update following the steps to list the available updates but I only have update for Xcode 12 and macOS Catalina.

    • Label: Command Line Tools for Xcode-12.4 Title: Command Line Tools for Xcode, Version: 12.4, Size: 440392K, Recommended: YES,
    • Label: Safari15.5CatalinaAuto-15.5 Title: Safari, Version: 15.5, Size: 92202K, Recommended: YES,
    • Label: macOS Catalina Security Update 2022-004-10.15.7 Title: macOS Catalina Security Update 2022-004, Version: 10.15.7, Size: 2033153K, Recommended: YES, Action: restart,

    So when I tried to update the os to BigSur I did it using Screen sharing and the Store but when I did this I got stuck and the machine didn't start so I rollback to the snapshot. Searching a little bit more I found on one site they said "Do not upgrade a computer unless you have physical access to it. Attempting to upgrade a computer remotely will drop the remote connection leaving the computer stuck waiting for local user input."
