MacSystemInfo 0.5

New in 0.5

• Choose how many years of history to keep. In the history window under History Storage → Keep history for, pick Custom (Years) and set anything from 1 to 50 years. Your choice is remembered.
• Safe changes. The new number only takes effect when you click Apply, and Cancel undoes it. If you shorten it, SystemInfo asks for confirmation before deleting older data.
• Still small. Measurement points are unchanged: 30-second values for the last 7 days, 15-minute averages up to 90 days, then hourly averages. Each extra year takes only about 1 MB.

SystemInfo 0.4 (Beta)

▎ SystemInfo 0.4 (Beta)
▎
▎ New in 0.4
▎
▎ - Hide gaps (asleep / off): a checkbox above the history charts squeezes out the time your Mac was asleep or shut down, so the charts only show recorded time. The gaps stay visible as narrow bands, and hover and zoom still work with the real times.
▎ - Sleep energy in Energy & Cost: the table now shows the energy used while asleep and the average power draw during sleep, for 24 hours, 7 days, 1 month, 6 months and 12 months.
▎
▎ Since 0.3
▎
▎ - Energy and cost for the selected range in the history summary, and totals for fixed periods with your price per kWh.
▎ - Start at Login toggle and a new app icon.
▎
▎ Requires macOS 27 or later. Install by opening the DMG and dragging SystemInfo onto Applications. On first launch, macOS shows a warning because this beta isn't signed with a paid Apple Developer ID. Open System Settings → Privacy & Security and click Open Anyway.

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.
