System
macOS controls both fans
The default and fallback. Smart Breeze verifies the handoff instead of trusting the selected button.
Smart Breeze for macOS · Public beta
Qualified fan control for long workloads.
On Mac16,7, Smart Breeze watches live temperatures, adds airflow before heat builds, then verifies the handoff back to macOS.

Smart Breeze is the new name for Breeze. Fan control is qualified only on Mac16,7. Build 24 can install on other Apple-silicon Macs, but sensor availability remains model-specific.

The same download behaves differently by model.
Smart Breeze checks the hardware after installation. Build 24 continues read-only sensor discovery when a Mac has no fan-count key, but the M5 Air path still needs physical verification.

Live control, visible state
See what Smart Breeze is doing.
On the qualified Mac, the active policy, selected sensor, fan targets, actual speed, and controller ownership stay in one view. System remains one click away.
- Switch between System, Smart Boost, and timed Max in one row
- Requested and actual fan speed remain separate
- Controller ownership is read back after changes
The product
System, Smart Boost, or timed Max.
Each mode states who owns the fans, what Smart Breeze requested, and what the hardware actually reports.
Smart Boost
Your curve requests earlier cooling
Smart Breeze watches the selected sensor and releases control when the curve no longer calls for extra airflow.
Timed Max
Full cooling for a deliberate interval
Use it for a render, export, game, or another short workload. The timer ends in verified System control.
Smart Boost
Set how early your fans respond.
A temperature-to-fan curve turns one live sensor reading into a bounded target. The Balanced profile below is an example, not a benchmark or a performance claim.

Hardware beta
Help qualify another Apple-silicon Mac.
Selected testers follow a written plan for fan control or fanless sensor compatibility. Completing the assigned plan qualifies for a complimentary license to the first paid full release.
Current public beta
Build 24, signed and checksum-verifiable.
Download the notarized DMG for this release. Installation and helper approval are documented before you enable fan control.
