macOS support arrives with XDM 9
XDM 9 is coming soon, with a native macOS build. This guide describes how installation will work. Older 7.x builds for macOS are outdated and not recommended.
Which download do I need?
| Your Mac | File |
|---|---|
| Apple silicon (M1, M2, M3, M4 and later) | xdm-app-<version>-arm64.dmg |
| Intel processor | xdm-app-<version>-x64.dmg |
Not sure? Open → About This Mac. “Chip: Apple M…” means Apple silicon.
Install step by step
- Open the DMG you downloaded. A window named XDM appears.
- Drag the XDM app onto the Applications folder shortcut in that window.
- Eject the DMG and open XDM from Applications or Launchpad.
- If macOS says it can't verify the developer, click Done, then open System Settings → Privacy & Security, scroll down and click Open Anyway next to the XDM message. Confirm once more. macOS remembers the choice.
- Install the browser extension from the Set up browser integration window that opens on first start.
Why the security prompt?
XDM is free, open-source software and isn’t notarised through Apple’s paid developer program, so Gatekeeper asks you to confirm the first launch. The app is still code-signed (ad-hoc), and you only need to confirm once.
Notifications
If you choose Notification under Settings → General → Notify me with, macOS asks for permission the first time. If you said no earlier, XDM offers to open System Settings → Notifications so you can allow it.
Uninstall
Quit XDM, then drag it from Applications to the Bin. To remove settings and the download list as
well, delete the hidden folder ~/.xdm-app.
