About

MainframeMac brings the MainframeMonitor console to macOS as a native Mac app. Live CPU, memory, storage and network values in the familiar green or amber CRT look — and, as the highlight, the Parallel Sysplex: Mac, iPhone and iPad find each other on your local network and appear side by side as coupled systems.

What leaves your device

A system and network monitor can only measure the network by using it. Here is everything the app sends — none of it reaches me, and there is no server of mine involved.

Traceroute — When you start a trace, test packets go to the destination you enter; every router on the way sees your public IP address.
Route map — To place the hops on the map, their IP addresses and your public IP are looked up at freeipapi.com.
Latency & clock — While the latency panel runs: a ping per second to 1.1.1.1 (Cloudflare) and a time query to time.apple.com every five minutes.
Sysplex — Couples Mainframe apps on your local network via Bonjour and shares device name, model and live stats with them — never over the internet.
My other apps — Icons in the ‘More apps’ section are loaded from Apple’s App Store servers.
