Using an M5 MacBook Air?

Build 21 installed on one tested fanless M5 MacBook Air but stopped sensor discovery when the Mac did not expose a fan-count key. Build 22 continues read-only temperature discovery and adds a sensor explorer, but that path still needs physical verification on the M5 Air. Fan control is never expected on that Mac, and the fan helper is not a sensor workaround.

Check before installing

Confirm what the current signed build can do on your exact Mac and understand its safety limits.

• Check your Mac before enabling fan control: Check model, macOS, monitoring, and fan-control support.
• Extra cooling that fails closed: Understand verified writes, safe recovery, and important limits.

Install or remove Smart Breeze

Keep one copy in Applications and let macOS manage the privileged helper when fan control is available.

• Install one canonical copy: Install the signed DMG in Applications and verify the release.
• Why Smart Breeze asks for approval: Learn why fan control needs approval and how repair works.
• Remove Smart Breeze without guessing about fan ownership: Verify macOS fan ownership before removing the helper and app.

Understand or solve a problem

Start with the symptom, then compare it with the current build’s documented limits and release notes.

• Understand what Smart Breeze is telling you: Interpret monitoring, temperature, approval, and ownership states.
• Known issues and current limits: Check current limits, including the tested M5 MacBook Air issue.
• What changed in Smart Breeze: Confirm the current signed artifact and what changed by build.
