Get Mailwing for macOS

System requirements

• macOS 11 Big Sur or later
• Universal binary — runs natively on Intel and Apple Silicon
• ~250 MB free disk space

Install

1. Click Download above to grab the DMG.
2. Open the DMG and drag Mailwing to /Applications.
3. Double-click to open — that's it.

Signed & notarized

Mailwing is signed with an Apple Developer ID certificate and notarized by Apple, so macOS opens it with a normal double-click — no right-click, no Gatekeeper override. Every build is produced in the open by GitHub Actions, so you can audit exactly what shipped.

Install via Homebrew

If you prefer a single command, the Homebrew cask handles download and placement for you:

brew install --cask vinaysamtani/mailwing/mailwing

Make Mailwing your default mail client

Open Mailwing → menu bar Mailwing → Set as default mail client. Or via System Settings → Default Web Browser (for mailto: links).

Troubleshooting

"Mailwing is damaged and can't be opened"

Almost always a corrupted download — re-download the DMG. If it persists, clear the quarantine flag:

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

App quits immediately on first launch

Open Console.app, filter for Mailwing, then try to launch again. If you see a useful stack trace, please open an issue with the log.

How do I uninstall?

Drag /Applications/Mailwing.app to the Trash, then remove the user-data directory at ~/Library/Application Support/mailwing if you also want to clear accounts and notes.
