Macenize · Native Mac software

Instruments for people who build things.

We make small, native macOS tools with an unusual obsession: every number they show you is one we can defend. No Electron, no telemetry, no numbers that sound right.

What we ship

One tool out now, built to a standard we can keep. More will follow only when they meet it.

Mac Vitals

A system monitor for builders. Per-core CPU, memory pressure, GPU, disk and network in your menu bar — plus live tokens per second from the language models running on your own Mac. Under 1% of one core.

We would rather ship one instrument that is right than four that are plausible. The next one is being measured now.

02 · Approach

Measured, not estimated

Most monitoring software is confident. Ours is checked. Three rules we hold ourselves to, because breaking them is how a tool ends up lying quietly for months.

Rule 01

Compare against the kernel

Every reading is checked against what the system itself reports. That habit is how we caught our own memory readout describing occupancy instead of pressure — a number that would have read 98% on any healthy Mac, forever.

Rule 02

Publish the method

CPU is a CPU-time delta over a fixed window, not a decaying average. Memory is phys_footprint, not resident size. A benchmark whose method is hidden is a marketing number.

Rule 03

Say what it costs

A monitor that is expensive to run is a contradiction. Ours states its own footprint, in the app and on this page, and there is a refresh-rate control labelled with its real cost in CPU.

03 · Data

Nothing leaves your Mac

No accounts. No analytics. No crash telemetry. No "anonymous usage statistics". Our tools read your machine and show you the result — the only outbound connections are ones you configure yourself, like a webhook you wrote or a server you own. This is a design constraint, not a setting.
