## Install

### Homebrew

```bash
brew tap hoobnn/tap
brew install --cask fanfan
```

### Manual

Download the latest DMG from [Releases](https://github.com/hoobnn/fanfan/releases/latest), or run the install script:

```bash
curl -fsSL https://raw.githubusercontent.com/hoobnn/fanfan/main/scripts/install.sh | bash
```

Requires macOS 26+ (Apple Silicon or Intel). One password prompt on first launch — that's it.

## How it works

Writing fan speeds requires root. Instead of running the whole app as root,
fanfan installs a tiny C LaunchDaemon that owns the SMC handle and accepts
exactly three commands over a Unix socket: `PING`, `SET`, `AUTO`.

```
fanfan.app  ──unix socket──▶  fanfan-smcd (root)  ──IOKit──▶  SMC
```

The app itself runs unprivileged. Temperature reads go straight through IOKit.
