Does iCUE work on Mac?

No. iCUE, including its Xeneon Edge widget layer, is Windows-only. Corsair has not shipped a macOS version. On a Mac, the Xeneon Edge panel connects and displays as an ordinary second monitor, but nothing populates it — iCUE is what would normally drive the widget grid, and iCUE does not run on macOS.

What is the Mac alternative to iCUE for the Xeneon Edge?

Vardek. It is a separate, Mac-native application — not a port of iCUE — that fills the same 2560x720 panel with a full-screen, touch-driven widget grid. It uses its own manifest.json plus index.html widget format, not iCUE's current .icuewidget package format.

Comparison

iCUE vs Vardek

Xeneon Edge on Mac · updated August 2026

Corsair ships the Xeneon Edge™'s widget layer through iCUE, and iCUE is Windows-only. On macOS, the 2560×720 panel connects fine — it's just a second display — but nothing populates it. Vardek is a separate, Mac-native application that fills that gap: it isn't a port of iCUE, and it doesn't read iCUE's widget format — Vardek widgets use their own manifest.json + index.html spec, close in spirit to iCUE's original format but not interchangeable with Corsair's current CLI-packaged .icuewidget pipeline.

The network-model and telemetry rows describe Vardek, which is documented in its own privacy page. Corsair does not publish equivalent detail for iCUE, so no claim is made about it either way — only what's actually known is listed.

What doesn't change

Vardek doesn't touch RGB lighting, fan curves, or any of iCUE's other peripheral control — that's out of scope entirely. It exists for one job: drive the Xeneon Edge widget panel on a Mac, the way iCUE drives it on Windows.

Bringing your own widgets

Widgets built for iCUE's current Xeneon Edge widget layer are packaged as .icuewidget files via Corsair's CLI and use a different manifest schema — they don't import into Vardek unmodified. Vardek has its own manifest.json plus HTML entry file format instead; see the widget authoring guide for the spec and Vardek's own add-on widget catalog.

Try it

Vardek runs full-screen on any macOS display, so it's possible to try before a Xeneon Edge panel arrives — see the Mac display setup guide for recommended window sizes if you don't have the panel. Download for macOS — free, signed, and notarized by Apple.
