Your Mac's vitals in the menu bar, with a pixel duck that acts them out.

CPU, memory and storage next to a duck that walks faster when your Mac works hard, flies while it charges and naps when you're away. Turn the numbers off and keep just the duck.

The duck in this page's menu bar, up top, 8 times bigger.

The numbers turn yellow, then raspberry, when something needs a look.

Questions

I can't see the duck

On Macs with a notch, items can hide behind it when the menu bar is crowded: quit or hide other menu bar items to make room. macOS 26 also asks you to allow new menu bar items, in System Settings under Menu Bar.

What do the numbers mean?

CPU is how busy the processor is: yellow from 70 %, raspberry from 90 %. MEM is memory in use; its colour follows macOS memory pressure, not the percentage. SSD is free space: yellow under 10 % free, raspberry under 5 %.

Does it use much battery?

No. Measured on an 8 GB Mac: about 1 % of one CPU core while the duck walks and under 0.5 % while it rests, an energy impact around 1 in Activity Monitor. It also slows down on battery, in Low Power Mode, with Reduce Motion and when the menu bar is hidden.

Does it show temperatures?

No degrees. The duck follows macOS's own heat warning (warm, hot, very hot), the same signal the system uses to slow down.

How do I restore the unlock on a new Mac?

Choose Restore purchases in the duck's menu. Apple restores it for the same Apple Account.

Refunds?

Apple handles refunds: ask through the Mac App Store's "Report a Problem" page for your purchase.

Does it start when I log in?

Yes, if you turn on Open at login in Settings; macOS lists it under Login Items.

More help on the support page, or write to support@menubuddies.app. There is no form and no ticket system: it is an email.
