System Vitals Monitor

A released native SwiftUI monitor that keeps aggregate CPU, GPU, memory pressure, thermal state, battery, network, disk, and power information visible in a private, compact Mac dashboard.

The Challenge

Balancing useful aggregate monitoring with Mac App Store sandbox limits, removing unavailable panels instead of advertising dead ends, and keeping periodic sampling lightweight.

System Architecture

SwiftPM-packaged macOS architecture coordinating a unified Observable telemetry store. Decouples raw hardware samplers from UI rendering, utilizing background dispatch queues to prevent UI thread blocking.

Hardware Telemetry Pipeline

SPEC ID: MACVITALS-SYS-01

PHASE 01

ProbingOS Kernel Telemetry

Extracts live hardware loads using IOKit and Host APIs.

→

PHASE 02

SamplingObservable Store

Debounces sensor values onto background dispatch threads.

→

PHASE 03

SandboxingApp Entitlements

App Store sandbox compliance filter gates private APIs.

→

PHASE 04

RenderingSwiftUI Dashboard

Updates graphs, widgets, and menu bar indicators.

Implementation Notes

Engineered aggregate CPU and per-core load, GPU, memory, storage, network, battery, power, and public thermal-state sampling with explicit Store-safe capability paths.
Designed compact and pinned views, customizable widgets, local 24-hour History, alerts, and on-demand disk and network checks.
Published version 2.0 as a free Mac App Store utility with live monitoring, compact and menu-bar modes, one-hour History, and one complete 30-minute Advisor result.
Lifetime Pro is an optional one-time purchase that adds deeper Advisor sessions, saved reports, retests, exports, 24-hour History, alerts, and active disk and network tests.
