Power
- Battery percentage: The built-in way to show battery percentage on a Mac (Tahoe, Sequoia, Sonoma, Ventura), and how to get time left, bigger meters and low-battery alerts too.
- Mouse and keyboard battery: macOS hides Bluetooth accessory battery levels inside the Bluetooth menu. Here is how to keep a Magic Mouse, Keyboard or Trackpad battery visible all the time.
- Power draw in watts: Keep your MacBook’s live power draw in watts in the menu bar, notice background work burning battery, and estimate time left. Apple silicon and Intel.
System
- CPU usage: Put live CPU usage in the Mac menu bar as a needle gauge, ring or graph, with an alert when it stays high. How often it updates and what it costs to run.
- Memory usage: Keep RAM usage in the Mac menu bar, using the same Memory Used figure as Activity Monitor, with an alert before you run out.
- Free disk space: Watch how full your Mac’s disk or an external drive is from the menu bar, counted the way Finder counts it, with a warning before it fills up.
- Network speed: macOS can’t show live internet speed in the menu bar. Here is how to show download and upload speed as a number or a graph, and what the number means.
- Thermal pressure (instead of CPU temperature): What macOS thermal pressure (Nominal, Fair, Serious, Critical) means, why it tells you more than a CPU temperature, and how to keep it in your menu bar.
- Fan speed: Keep fan speed in RPM in the Mac menu bar to hear trouble before it starts. Works on Macs with fans, read only, in the direct download version of Multimeter.
Time
- Timer (Pomodoro): A focus timer that lives in the menu bar: click to start, pause or reset, see the time left at a glance, and get a notification when it’s done. Default 25 minutes.
- Countdown to a date: Days and hours to a launch, a deadline or a trip, always in the Mac menu bar, with a bar that empties as the date gets closer.
- Day, week, month and year progress: A meter that fills as the day, week, month or year goes by. A quiet nudge in the Mac menu bar, updated every minute.
Your numbers
- Build and deploy status: Show passing tests, failed CI runs or shipped commits in the Mac menu bar with a one-line multimeter:// link or a script. Recipes for local builds and GitHub CLI.
- Server and homelab load: Show a homelab or VPS load average, disk use or container count in the Mac menu bar with an ssh one-liner in a Script meter, or a JSON status endpoint.
- Any number from a web address: Point a Multimeter meter at a URL that returns a number or JSON, pick the value with a key path like data.amount, and keep it in the Mac menu bar. Examples included.
