Macvital

Check macOS hardware health: CPU usage, RAM pressure, disk space, temperatures, and top processes. Returns a quick status summary or full breakdown. USE WHEN: User or agent wants to know if the Mac is under load, running hot, low on disk, or RAM-constrained. Also use before spawning heavy tasks to check if the machine has headroom, or when diagnosing performance issues. DON'T USE WHEN: User asks about network speed, battery health (use a battery-specific tool), or remote machine health.

macOS hardware health monitor. Checks CPU, RAM, disk, temperature, and top resource hogs.

Requirements

• Python 3 (pre-installed on macOS)
• Script: scripts/macvital.py
• Temperature data requires sudo (Apple Silicon only)

Commands

bash

# Quick one-line status (good/warn/critical with icons)
python3 scripts/macvital.py status
python3 scripts/macvital.py status --json   # machine-readable

# Full breakdown
python3 scripts/macvital.py detail

# Top CPU and RAM processes
python3 scripts/macvital.py top
python3 scripts/macvital.py top --n 10

# Temperature only (more accurate with sudo)
python3 scripts/macvital.py temp
sudo python3 scripts/macvital.py temp

# Exit code check (for scripting: 0=ok, 1=warn, 2=critical)
python3 scripts/macvital.py check

# Continuous monitoring
python3 scripts/macvital.py watch
python3 scripts/macvital.py watch --interval 10

Thresholds

Metric	Warn	Critical
CPU	70%	90%
RAM	75%	90%
Disk	80%	90%
Temp	80°C	95°C

Typical Use (agent workflow)

bash

# Before a heavy task
python3 scripts/macvital.py check
# exit 0 = safe to proceed, exit 1/2 = consider waiting

# Quick heartbeat line
python3 scripts/macvital.py status

# Diagnosing slowness
