Download Wopener

Free and Apache 2.0 licensed. Grab the latest build, or compile it yourself.

macOS 26.0 or later. Not yet notarized, so macOS blocks it on first launch — the one-time fix is right below. Kimchi's funding it.

First launch on macOS

Wopener isn’t notarized yet (that costs $99/yr from Apple), so Gatekeeper steps in the first time you open it. Kimchi sponsored the Apple Developer Program, so notarized builds are on the way — until they ship, this is a one-time dance: do it once and macOS never bothers you again.

Right-clicking Wopener in the Applications folder and choosing Open from the context menu. — 1 Right-click and choose Open

Double-clicking shows a dead-end "can’t be opened" alert. Instead, right-click (or Control-click) Wopener in your Applications folder and choose Open.

The macOS Gatekeeper dialog with an Open button that launches Wopener. — 2 Click Open in the dialog

The same warning appears, but this time with an Open button. Click it once — macOS remembers your choice and never asks again.

Prefer System Settings?

Open Wopener once, then go to System Settings ▸ Privacy & Security and click Open Anyway. Or, from a terminal:

xattr -dr com.apple.quarantine /Applications/Wopener.app

System Settings ▸ Privacy & Security showing the Open Anyway button for Wopener.
