SystemWoe vs Activity Monitor
Activity Monitor is the right first stop for “what’s using CPU?” SystemWoe starts where that story ends: disk and network pressure, named culprits, and safe next steps.
Verdict
Keep Activity Monitor for Apple’s built-in baseline. Use SystemWoe when you need sortable disk/net I/O, “what is this process?”, and Free Resources that won’t silently wreck protected work.

| Docker awareness | — | Pro |
| Prometheus + MCP (localhost) | — | Pro Integrations |
| Price | Bundled with macOS | Free + Pro from $49 |
Pick Activity Monitor when
- You only need a quick CPU or memory glance
- You want Apple’s default UI with zero install
- You’re debugging something that needs private Apple task ports (SIP helpers)
Pick SystemWoe when
- The disk or network feels busy and AM won’t name the writer
- You don’t know what
mds_storesor a helper is - You want to free capacity without killing a keep-guarded build or Docker Desktop
Honest limit: some root / SIP processes appear in Activity Monitor with rates third-party apps cannot fully match via public APIs. SystemWoe keeps best-effort caveats and uses path Watch + Services insight for “what is the disk doing?”
