Bondi for Apple Mac
Bondi is a native macOS system monitor with on-device AI. It tells you why your Mac is slow, in one plain sentence.
A dev server called Vite is sitting idle in a project called shop. It has been idle for 3h 20m and holds 612.0 MB.
Your data never leaves your Mac.
Alpha nowLaunch 2 Feb
Click a card, a link, or a tab. This is Bondi's window running on made-up numbers; on your Mac it reads the real ones, and they never leave it.
Apps, not processes
A browser is dozens of helper processes, so no single row in Activity Monitor looks big. Bondi adds each one to the app that started it. Both lists here are one real reading of the same Mac.
How it works
On Macs with Apple Intelligence, Bondi writes with Apple's own on-device model: the one built into macOS, running on your Mac's Apple silicon. It never goes to the cloud, and it never gets to make up a number.
Every figure is worked out in code from your Mac's own readings.
A problem, the disk, the battery, something idle, or all calm: Bondi decides what matters.
The on-device model adds the plain English, on your Mac. The figures stay Bondi's.
Wrong tone, wrong subject or any number: Bondi uses its own sentence instead.
Features
Why is my Mac slow?
Click the link. Bondi explains what's using your Mac, what's idle and holding memory, and what changed in the last hour. Apple's on-device model writes the opening; every figure is Bondi's.
Apps, not processes
Every helper counts toward the app that started it. Switch between CPU, Memory and Energy.
Ask your history
Bondi answers from this Mac's history. The model only writes the words around those figures.
Warnings
When memory runs short, the menu bar says so and the popover names the cause with one fix. Try the button: Bondi always asks first.
For developers
Claude Code and Cursor start dev servers and forget them. Bondi finds the ones still holding memory. Vite, in a project called shop, has been idle for 3h 20m and holds 612.0 MB. Kubernetes is next.
Docker
Local AI30-day history
Real CPU history from a working Mac. Switch the range and move across the chart; shaded time is when the Mac slept.
Menu bar
Click Bondi's icon. About 0.3% of one CPU core while it waits.
Sound
Turn a call up to 300% and the music down, without touching the rest.
Above 100% can distort and may be too loud for speakers or ears.
Fan boost
Drag to boost. Never slower than your fans already were, and back to Auto when you quit.
Process guide
Click a process. Bondi's own notes on 125 common macOS processes, with what each is using right now.
Your Bondi
Pick one: this page's icons change with it, as Bondi's Dock icon does.
Keyboard shortcuts
Press ⌘ and a number to jump straight to a tab, or ⌘+ and ⌘− to step through them. They work in Bondi's window and in the menu bar.
⌘8 opens Battery on Macs that have one. Bluetooth has no number: step to it with ⌘+ or ⌘−.
Every star is a real process from one reading of a working Mac, and each app gets exactly its own.
How Bondi compares
Activity Monitor, iStat Menus, Stats and Vitals are good at showing what your Mac is doing. Bondi says what it means, in a sentence.

Guides
Straight answers to what people ask most, from real readings of a real Mac. Each links to the full guide.
MacBook or iMac, it's almost always one of four things: memory running short, one app working hard, macOS doing background work, or the Mac protecting itself from heat.
Add up each app's helper processes. In one real reading, Chrome was 80 processes and 12.23 GB of RAM, more than all of macOS.
macOS is compressing a lot of memory to fit everything in. Green is fine, even when Memory Used looks high; red means it's swapping to disk, and that's when a Mac slows down.
The chip is making more heat than the Mac can lose quietly, so the fans speed up. Find what's working hard, give it air, and they settle within minutes.
Your Mac is hot. macOS takes CPU time on purpose so apps slow down and the heat drops. It's a safety feature, not malware.
It draws everything on your screens. Many windows, several or very high-resolution displays, screen recording or video push its CPU up.
macOS is catching up: Spotlight, Photos and iCloud. It settles on its own, usually within hours, faster if the Mac stays plugged in and awake.
If mds_stores or mdworker are near the top, Spotlight is indexing your files. It settles on its own, usually within a few hours; the guide covers indexing that seems stuck.
Activity Monitor shows the numbers; Bondi names the cause in one sentence. MacBook or desktop Mac, it's almost always one of four things: memory running short, one app working hard, macOS doing background work (Spotlight, Photos and iCloud catch up after an update), or the Mac slowing itself down because it's hot. Our guide shows how to tell which one it is.
Bondi is in alpha now. The beta is next, and full launch is Tuesday 2 February 2027, 8 am Pacific. You'll be able to buy a license at launch. Join the beta to try it first, or sign up for updates. See the roadmap.
At full launch, Tuesday 2 February 2027: a 14-day free trial with every feature, no credit card required, then a one-time purchase for one Mac, with no subscription. The first 250 licenses cost $9.99; after that, $24.99. We'll say so before the price rises. Students pay $9.99 at launch, then $12.99, by emailing support from a .edu address. Updates and the on-device AI are included.
On Macs with Apple Intelligence (macOS 26, Apple silicon), Apple's on-device foundation model, built into macOS. Other Macs can download a small free open model (Qwen2.5 0.5B) from Bondi's Settings; nothing downloads unless you press Download. Either way it runs on your Mac.
No. History stays in a file on your Mac, and the AI runs on your Mac. Bondi only contacts our server to check your trial or license, and to look for updates. See the privacy policy.
Yes. Everything it measures, its history and its AI run on your Mac. It goes online only to check its trial or license and to look for updates.
Any Mac with macOS 15 or later, Apple silicon or Intel: MacBook Air, MacBook Pro, iMac, Mac mini, Mac Studio and Mac Pro.
Yes. Bondi is an Activity Monitor alternative, and it works alongside Activity Monitor. Activity Monitor, built into macOS, lists every process: 966 rows on one real Mac. Bondi adds each helper to the app that started it (39 apps on that Mac), keeps 30 days of history, and tells you in one sentence what's slowing the Mac down. More in Bondi vs Activity Monitor.
Yes: Activity Monitor, built into every Mac, is the equivalent of Task Manager on Windows. Open it with Command-Space, type "Activity Monitor" and press Return; to close a stuck app, press Option-Command-Esc for Force Quit. Bondi is a task manager that explains: it groups processes into the apps you know, tells you in one sentence what's slowing the Mac down, and asks before it quits anything.
Yes. All four live in the menu bar and can control your fans. Going by each app's own website, Bondi is the only one that tells you in a plain sentence why your Mac is slow, written on your Mac by an on-device AI, and the only one that explains 125 macOS processes by name. It also shows local AI models (LM Studio, Ollama) beside your dev servers and Docker containers. See the full comparison.
It depends on what you need. For seeing every reading in the menu bar, iStat Menus ($11.99) or Stats (free and open source). For understanding them, Bondi: it groups processes into apps, keeps 30 days of history and tells you in one sentence what's slowing your Mac down. See Bondi vs Activity Monitor, iStat Menus, Stats and Vitals.
Yes. It groups dev servers by project and port, and shows Docker containers and local AI models (LM Studio, Ollama) with the memory each holds. Stop or unload any of them; Bondi asks first.
No. With its windows closed, Bondi uses about 0.3% of one CPU core, and the AI only works while you're looking.
Never. It suggests one fix at a time and asks before it quits, stops or unloads anything.
The menu bar keeps showing your CPU for free. Everything else waits for a license.
Yes. See the refund policy; Paddle, who handles the payment, issues it.
