🌀 MacFan v1.0.0 — Universal Apple Silicon Fan Control
Highlights
- Works on any Apple Silicon Mac (M1 and later) — desktops and laptops. Every fan is discovered dynamically and controlled together, each converted to its own RPM range; fanless Macs (MacBook Air) are detected as passively cooled.
- Menu bar app with live temperature and per-fan RPM, a temperature-tinted status icon, and smooth animations throughout.
- Manual mode: percentage slider applied to all fans, with verified writes — the helper reads back fan mode and actual RPM and re-asserts the target when macOS overrides it.
- Curve mode with an interactive editor: drag points on the chart, double-click to add, right-click to delete, plus compact chips for precise values.
- Fully bilingual (English/Spanish): follows the macOS language, switchable instantly in Settings > General.
- Safe by design: read-only until you authorize a narrow privileged helper (one-time macOS approval); no Accessibility permission, no analytics, no network access.
- Also includes a
macfanCLI with dry-run-by-default writes.
Formerly known as M4FanControl — v1.0.0 renames the project and makes it universal.
