System Monitor Widgets#

ExtraDock 4 includes compact gauge widgets for CPU Usage, Memory Usage, GPU Usage, and Battery.

Add them from Dock Items → Add Widget. Each widget has its own settings: Color (Automatic, which shifts from green to amber to red, or Fixed), Text Color, Update Rate (1, 2, 5, or 10 seconds; 2 seconds by default), Number Size, and, except for Battery, a Label under the number.

GPU data depends on what the current Mac and macOS expose. An unavailable reading is shown as unavailable rather than estimated. Battery is useful on portable Macs and other systems where macOS reports a battery.
