SystemInfo 0.3 (Beta)

A small system monitor that lives in your Mac's menu bar.

What's new

• Energy & Cost in the history window. See how much energy your Mac used over the last 24 hours, 7 days, 1 month, 6 months and 12 months. Enter your electricity price per kWh to see what it costs.
• Energy and cost in the history summary. The Summary at the top of the window now also shows the energy used and the cost for the range you're viewing, including when you zoom in.
• Start at Login. A new toggle in the menu bar panel adds SystemInfo to your login items. Untick it to remove it again.
• New app icon, also used for the installer.

Features

• Live CPU, RAM, disk and power (watts) in the menu bar, updated every 2 seconds. You choose what's shown.
• History charts from 1 hour to everything, with drag-to-zoom and hover values.
• Sleep tracking: when your Mac slept, for how long, and how much energy it used.
• Small storage footprint: a full year of history takes about 5 MB.
• Private: all data stays on your Mac, with no network connections.

Requirements

• macOS 27 or later.
• Power values need a Mac that reports its power consumption, such as current Apple silicon Macs, including the Mac mini. Other Macs show "Not available" for power, and everything else works.

Installation

1. Download SystemInfo-0.3.dmg below.
2. Open it and drag SystemInfo onto Applications.
3. Launch it. It appears in the menu bar, not the Dock.

First launch: this beta isn't signed with a paid Apple Develwarning. Open System Settings → Privacy & Security and clickOpen Anyway next to "SystemInfo was blocked…". You only need to do this once.

A ZIP (SystemInfo-0.3.zip) is also provided as an alternative download.

Notes

• Energy totals only cover time SystemInfo has recorded. Theo need the Keep history for setting to be long enough, andincomplete periods are marked with an asterisk.
• Beta software, so expect some rough edges.
