## What it is
mactop is a terminal-based system monitoring tool for Apple Silicon Macs, written in Go with CGO. It displays real-time CPU, GPU, ANE, power, temperature, fan, memory, network, and disk metrics in a terminal UI without requiring sudo.

## Use cases
- monitor cpu and gpu usage on apple silicon mac from terminal
- view power consumption and temperatures on m1/m2/m3/m4/m5
- track fan speeds and thermal state on macbook
- monitor memory swap and network usage in terminal
- watch dram bandwidth and gpu frequency in real time
- alternative to asitop without sudo
- monitor disk io and battery status on mac

## When to choose
- you have an Apple Silicon Mac and want real-time hardware metrics in the terminal
- you want a sudo-free alternative to asitop
- you need per-core E/P/S-core detail, fan, thermal, and power telemetry

## When to avoid
- you are on Intel Mac or Linux/Windows
- you need GUI-based system monitoring
- you need historical metric storage and dashboards beyond the built-in TUI

## Facets
- artifact type: cli-tool
