## プロジェクトの歴史と使われ方

mactop is a terminal system monitor for Apple Silicon Macs. The project describes itself as a `top`-style monitor for real-time Apple Silicon CPU, GPU, ANE, DRAM, power, temperature, fan, process, and I/O metrics.

### プロジェクトの歴史

The tool is written in Go with CGO and uses native Apple APIs such as SMC, IOReport, IOKit, and IOHIDEventSystemClient. Its official README frames it as Apple Silicon only, requiring macOS Monterey 12.3 or later.

### 採用の歴史

mactop became useful in the Apple Silicon era because many traditional Unix monitoring tools do not expose SoC-specific measurements such as efficiency and performance cores, GPU frequency, Neural Engine activity, and power telemetry. Its official repository shows Homebrew installation instructions and a public GitHub project with substantial stars and forks for a platform-specific system tool.

### 使われ方

Users normally run `mactop` interactively for a terminal UI. The README also documents flags for update interval, foreground and background colors, headless JSON output, output formats such as YAML and CSV, Prometheus metrics, and optional menu bar mode.

### パッケージ好きにとっての重要性

mactop matters to package and systems people because it fills a macOS-on-ARM observability gap from the command line. It is the kind of package developers install immediately after getting Apple Silicon hardware because it exposes metrics that `top`, `htop`, and cross-platform libraries often do not provide.

### タイムライン

- Public repository: Official Git tags start at v0.0.1.
- Current README: Documents Homebrew installation, headless output, Prometheus metrics, menu bar mode, and support for all Apple Silicon models.

### Related projects

- mactop is related to traditional terminal monitors such as top and htop, but targets Apple Silicon-specific telemetry through macOS native APIs.
