Coreloom
Now on Mac — Apple silicon and Intel

See everything your computer is doing.

Coreloom is a free, open-source hardware monitor for Mac and Windows. Live readings from every sensor, a gaming hub, benchmarks and a one-click clean-up, in one calm dashboard.

Coreloom's Overview on a Mac: a picture of the Mac, gauges for the processor and graphics, charts and memory, storage and network panels.

What it does

One app for the whole machine.

The same Coreloom on both systems, speaking each one's language: Metal, IOReport and the menu bar on a Mac; NVML, the tray and Task Scheduler on Windows.

Live dashboard

Processor and graphics load, temperatures, clocks and power; memory pressure, storage and network, with charts of up to an hour and a health check for each part.

Gaming

Your Steam, Epic and other games in one library with Play, plus the switches that matter: Game Mode, full power, keeping the Mac awake and Apple's Metal HUD, or the frame limiter and boosts on Windows.

Benchmarks

A CPU benchmark with single- and multi-core scores, a GPU benchmark on Metal or Direct3D, and a stress test that checks every answer, with every result saved.

Smart Optimize

One scan finds caches, logs and leftovers, checks your Mac's or PC's protection and the apps that start at login, and cleans up only what you tick.

Devices

Bluetooth accessories with their battery levels, connect and disconnect in a click, and everything plugged in by USB, Thunderbolt or a display cable.

Alerts and readings anywhere

Notifications when a reading stays past your threshold, readings in the menu bar or tray, an in-game overlay, and your computer's readings live on your phone over your own Wi-Fi.

Install on a Mac

Two minutes, then it updates itself.

Coreloom is free and open source, so it isn't sold through the App Store. macOS asks you to confirm it once, the first time you open it.

Drag it into Applications

Open the downloaded disk image and drag Coreloom onto the Applications folder beside it.

Confirm the first opening

Open Coreloom from Applications. If macOS says it could not verify Coreloom, click Done, then open System Settings › Privacy & Security, scroll down and click Open Anyway.

That's it

Coreloom lives in the menu bar and the Dock. New versions arrive on their own: Coreloom › Check for Updates… installs one right away.

On Windows, run the installer: it installs for you alone with no administrator prompt, and Coreloom updates itself the same way (Settings › Updates). To check a download yourself, compare shasum -a 256 (Mac) or Get-FileHash (Windows) with the release's SHA256SUMS.txt.
Privacy by design

It reads. It never meddles.

Read-only monitoringNo overclocking, fan control or firmware changes. Ever.
No telemetryOnly update checks to GitHub, and Cloudflare when you run a speed test. Your phone connects over your own network.
Nothing added to gamesNo injection, so anti-cheat has nothing to object to.
Changes only on your clickEvery switch says what it does and turns off again.
