Download Umbra

The latest release, straight from GitHub — signed and notarized by Apple, so macOS opens it without a Gatekeeper warning.

Download for Mac (Apple Silicon)
Platform
macOS on Apple Silicon (M-series) only — no Intel Mac build, no Windows or Linux build yet.
Format
.dmg disk image, signed and notarized by Apple.
Updates
Umbra checks for updates automatically — the one disclosed network exception — and always asks before installing one. See the FAQ for the full privacy picture.

This link always resolves to the newest release, not a fixed version — it won't go stale as Umbra updates.
