macOS 26 Tahoe (Darwin 25) reached general availability on 2025-09 and is supported 3 years. Apple Intelligence on-device, Liquid Glass UI. This guide shows how to automate apple silicon control node setup 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.

Validation

ansible-playbook -i inventory/macos-26-tahoe.ini apple-silicon-control-node-setup.yml --check --diff
ansible-playbook -i inventory/macos-26-tahoe.ini apple-silicon-control-node-setup.yml

Confirm idempotency by running the playbook a second time — the play recap should report changed=0.

Troubleshooting

| Symptom | Likely cause | Fix | |---|---|---| | xcrun: error: invalid active developer path | CLT not installed | xcode-select --install | | Could not open a connection to your authentication agent | SSH agent missing | eval $(ssh-agent) && ssh-add | | Operation not permitted on /Library | TCC restriction | Grant Full Disk Access to Terminal in System Settings → Privacy & Security |
