ActivityLine

Native macOS menu-bar sparkline for CPU / GPU / RAM / network. One living line. Auto mode jumps to spikes. Everything stays on your Mac — no telemetry, no account.

Independent implementation inspired by activityline.app. Not affiliated. No Polar license.

Features

• Click the line to cycle Auto → CPU → GPU → RAM → Network
• Hover for who is loading the Mac + open Activity Monitor
• Right-click for modes, Launch at Login, network alerts, smoothing, About, Quit
• UI languages: English, Русский, Deutsch, Français, Español, 简体中文, 日本語, Português (Brasil), 한국어, Italiano, Українська, Polski

If you use Ice (menu-bar hider), pin ActivityLine so it stays visible.

Requirements

• macOS 13+
• Xcode 16+ (to build from source)
• XcodeGen (brew install xcodegen)

Install (build from source)

git clone https://github.com/sysrootix/activity-line.git

Why sandbox is off

IOKit / process sampling need it. See SECURITY.md.
