What is my disk doing?
Host disk + swap strip, cause chips (Spotlight, Time Machine, swap, Bonjour, Docker), and top writers — not just a sorted process table.
What on earth (Woe) is my system doing? See who’s using CPU, memory, disk, and network — in plain English — then free what’s safe.
Woe is short for What on earth?We briefly hesitated over a more… explicit expansion. App Store reviewers (and polite dinner guests) thank us for stopping.

Activity Monitor shows numbers. SystemWoe names the culprits — and what to do next.
Host disk + swap strip, cause chips (Spotlight, Time Machine, swap, Bonjour, Docker), and top writers — not just a sorted process table.
A growing encyclopedia explains Spotlight helpers, browsers, daemons, and more — available offline and kept current on Free and Pro.
Ranked Free Resources actions with keep-guards. Quit your own apps on Free; Pro adds force-terminate and Docker stop — never silent cleanup, never quit Docker Desktop.
Scan listening ports and see which process bound them. Soft or hard kill with keep-guards — no mystery lsof hunt.
Observe container CPU, memory, and disk I/O. Inventory stays optional and observe-only.
Two products, one mission. Purchasing Pro does not unlock features inside the Mac App Store Free app — Free stays free.

Disk rates are estimates (macOS buffer cache). Ports are snapshots, not packet capture. Prometheus and MCP bind to loopback only; MCP tools are read-only. SystemWoe never silently kills processes, writes exclude lists, or quits Docker Desktop.
