What’s new

Lower CPU usage.

• ImprovedLower background CPU usage: the storage breakdown shown in microIsland now refreshes every 6 hours instead of every 30 minutes, and waits while your Mac is under heavy load.
• ImprovedTemperature sensors are now read in the background, so the menu bar stays responsive even when your Mac is busy.

New app icon and menu bar icon.

• ImprovedNew app icon — a soft, tactile 3D redesign shared across all micro apps.
• ImprovedNew menu bar icon: three bars of a chart. Part of the refreshed line-icon family shared by all micro apps.

Redesigned onboarding.

• ImprovedCompletely redesigned onboarding, shared across all micro apps: a unified layout, a Back button on every step, and buttons no longer get cut off on smaller screens.
• NewReplay the guide anytime from “Getting Started Guide” in the menu.

A new menu bar icon.

• ImprovedNew menu bar icon: a live activity wave. Part of the unified icon family shared by all micro apps — clearer and easier to tell apart at menu bar size.

A brand-new app icon.

• NewRefreshed the app icon with a new layered design (Liquid Glass on macOS Tahoe).
• ImprovedThe attention badge (license / permissions) now also appears on text-style menu bar items, without covering the digits.
• ImprovedThe license entry in the menu bar is now consistent with other micro apps.

Accurate disk and network numbers.

• FixedDisk write bytes always showed 0.
• FixedPer-volume I/O showed 0 for every volume.
• FixedSome sensors were missed, and temperature used ℃ instead of °C.
• ImprovedBattery now shows measured power draw with a 24-hour history, and screen-on time has a 24-hour history too.
• ImprovedPacket loss appears in about 30 seconds instead of 100, and network details are shown even when Wi-Fi isn't the main route.
• FixedmicroStats could end up running twice at once.

Emergency fix for v0.1.1.

• Fixedv0.1.1 shipped with a startup regression: automatic updates and other background services never started. Because of this, v0.1.1 cannot update itself — if you are on v0.1.1, please download the latest version manually from this site.

Lighter on your Mac.

• ImprovedmicroStats itself now uses noticeably less CPU and battery: dropdown helpers stop completely the moment a menu closes, shared sensor reads are deduplicated, and battery info is sampled less often.
• FixedThe per-process network helper could keep running after the app quit unexpectedly. It now shuts down with the app, and any leftover from a previous session is cleaned up at launch.

Initial release.

• NewSix menu bar modules — CPU, memory, disk, network, sensors and battery. Each gets its own menu bar icon with nine display styles to choose from.
• NewRich dropdowns: per-process disk and network activity, measured energy use per app in watts (Apple silicon), temperature history charts, and hover over any graph to inspect past values.
• NewEverything stays on your Mac — no permissions required, nothing is ever sent anywhere.
• NewAvailable in 14 languages, with a 14-day free trial of every feature.
