This guide shows how to automate homebrew-based ansible install on macOS 26 Tahoe with Ansible end-to-end: prerequisites, an opinionated playbook using the community.general.homebrew module, validation, and troubleshooting.

Every example is tested with ansible-core 2.18 LTS on a Linux control node and is idempotent — re-running the playbook converges to the same state with zero changed tasks.
