macOS Sequoia (バージョン 15) には、Amazon EC2 インスタンスメタデータサービス (IMDS) を含むローカル IP ベースのサービスのユーザーに影響を与える新しいローカルネットワークプライバシー機能があります。

**重要**

**ローカルネットワークプライバシーポリシーを承認するには**

1. [インスタンスのグラフィカルユーザーインターフェイス (GUI) に接続する](connect-to-mac-instance.md#mac-instance-vnc).

1. 画面のプロンプトに従って、ローカルネットワークプライバシーポリシーを承認します。

1. ポリシーを承認したら、EC2 Mac インスタンスの AMI を作成します。詳細については、[Amazon EBS-backed AMI を作成する](creating-an-ami-ebs.md)を参照してください。
