Dynamic Island on Mac is a small SwiftUI surface. The closed notch is a Mac-native live-activity stack inspired by glanceable iPhone UI, not an iOS port. Disable it if you want the lightest possible notch.

What costs energy
Live polling and media artwork cost more than a static chip. Dynamic Island on Mac should sleep when unused.
How to lighten it
Turn off unused live activities in Settings so Dynamic Island on Mac is not in the stack all day.
