Agents

Know what your AI agents cost.

Coding agents and local models run all day. See each one’s share of your Mac, with every process it started.

The Agents tab: Cost to the computer, agents running with their share of the processor and memory, in a word, over the last few minutes. Claude Code with its sessions, each with processes, how long it has run, now and average processor, memory, energy and End Session; GitHub Copilot; Codex.

Activity

See the whole load, in plain words.

Apps, agents, background helpers and macOS itself, each with its share and a word for it.

Health’s Activity, Using Your Mac: a verdict first, naming the busiest; the processor and memory over the last few minutes, split into apps you use, AI agents, background helpers and macOS itself; then each group, with Light, Moderate or Heavy, a sentence, Details and Quit.

Balance the Load

Keep the load balanced.

It moves runaway background work to the efficiency cores and offers to quit idle apps. It asks first.

Balance the Load in the menu bar panel: yes, checked, using 10% of the Mac in the background and busy like this since it started a minute ago; on the efficiency cores it keeps working and leaves the fast ones to you. Cancel and Balance.
Found: a program we started for this picture.
After Balance the Load: Moved yes to the efficiency cores. What was moved used 100% of a core before and 100% now, on the efficiency cores. The Mac now: 14% of the processor and 14.53 GB of memory in use. Undo, Check Again and Done.
Done: what macOS reported after, with Undo.

A healthy Mac, for longer.

Questions

Will it run on my Mac?

Yes, on every Mac with macOS 14 or later, Apple silicon and Intel. Brello has no AI model in it, so it doesn’t need Apple Intelligence.

Does it need my administrator password?

No. Every reading comes from what macOS gives any app: its public interfaces and the tools it ships with.

Can it break anything?

Nothing changes without your yes. Quit, Force Quit, End Session and Balance the Load each ask first, with the name in the question. A process macOS needs, another user’s, and Brello itself are refused, with a sentence saying why.

Does it show temperatures and fans?

It shows the Mac’s heat in words, from macOS’s own reading, and the battery’s temperature. Not the processor in degrees or the fans: macOS gives apps no public way to read them.

Does it replace Activity Monitor?

For most people, yes: every process, the same five tabs, Quit and Force Quit, in plain words. Health and Activity Monitor compared.

Is it a subscription?

No. $10, one time, on up to 3 Macs, with refunds within 30 days and no reason needed. There’s no account.

What does Brello PI add?

An agent: type a sentence and get finished work, on Apple’s on-device model. It needs Apple silicon, macOS 27 and Apple Intelligence. Brello and Brello PI compared.
