Adds two columns to the Processes table (and rows to the inspector) next to Memory, which is the physical footprint: - RAM: pages currently in physical memory (ri_resident_size, from the proc_pid_rusage call that was already being made). - Compressed: the original size of the process's pages held by the compressor, via task_name_for_pid + TASK_VM_INFO. This is also the closest per-process swap figure: macOS pages out compressor segments, not processes, and those stay counted here. Activity Monitor's "Compressed Memory" and top's CMPRS report the same value. Both need no privileges for the user's own processes; other users' and system processes report 0, as the Memory column already did. Values match top/ps within sampling noise; a full refresh of ~650 processes including the extra call takes ~5 ms. Memory, RAM and Compressed live in one @TableColumnBuilder property: Table takes at most 10 columns per block, and inlining them also exceeded the type checker's time limit.

- Sort by any column (name, PID, CPU/Core, CPU/Total, Energy, memory, Disk I/O, threads, user, state)
- Process states: Running, Sleeping, Stopped, Zombie
- Context menu to terminate, force kill, suspend, or resume processes
- Deep-dive inspector (double-click / ⌘I): full executable path, launch arguments, open-file count, disk totals, energy, parent PID, Reveal in Finder
- Search processes by name or PID
Apps Tab
- View running user-facing applications
- Shows app icons, CPU/memory usage, and bundle identifiers
- Quick actions: Activate, Hide, Quit, Force Quit
- Copy bundle ID to clipboard
Performance Tab
- Real-time CPU usage graphs (global and per-core)
- Selectable time range (Live / 5m / 30m / 1h / 24h) backed by persistent history
- Memory usage visualization with donut chart
- Network throughput monitoring
- Support for Apple Silicon P-cores and E-cores
Power & Storage Tab
- System Health score (0–100) with plain-language diagnosis of what's wrong
- Recent Alerts inbox
- Battery & Power: charge, health (cycle-adjusted), cycle count, condition, temperature, power draw, time remaining, adapter wattage (via IOKit)
- System status: macOS version, uptime, thermal state
- CPU and GPU core counts
- GPU memory/VRAM usage
- Storage volumes with usage bars
- Network interface statistics
Proactive monitoring
- Alerts engine with native macOS notifications on sustained high CPU, critical memory pressure, disk almost full, thermal throttling, runaway processes, and low battery — de-duplicated so you're never spammed
- Persistent metric history stored to disk; trends survive restarts
Menu Bar
- Configurable menu-bar metric (CPU % / Memory % / Health / Download)
- Dropdown with live CPU/memory/network/GPU/battery, System Health score, and Top CPU Consumers with one-click quit
Settings (⌘,)
- Launch at login (SMAppService)
- Adjustable refresh interval (1–30 s)
- Notification toggle and alert thresholds (CPU, disk, low battery)
Requirements
- macOS 13.0 or later
- Xcode 15.0 or later (for building)
