Getting past the first launch.

Prebuilt desktop apps for macOS, Windows, and Linux are published on the Releases page for every v*.*.* tag from v1.13.1 onward — earlier tags are macOS-only.

Platform	File	Notes
macOS (Apple Silicon)	Udaan_<version>_aarch64.dmg	M1/M2/M3/M4
macOS (Intel)	Udaan_<version>_x64.dmg	Intel Macs
Windows	Udaan_<version>_x64-setup.exe	NSIS installer
Linux	Udaan_<version>_amd64.AppImage or .deb	AppImage is portable; .deb for Debian/Ubuntu

The app is self-signed (not signed by a CA-trusted/registered publisher), so each OS will show a one-time warning before the first launch. This is expected — follow the steps below to open it.

macOS

1. Open the downloaded .dmg and drag Udaan into Applications
2. On first launch, Gatekeeper will say “Udaan cannot be verified” — right-click the app → Open → Open in the dialog
3. If you instead see “The application is damaged and can’t be opened”, clear the quarantine flag:

   xattr -d com.apple.quarantine /Applications/Udaan.app

   This manual step is only needed once, on your first install (or if you’re updating from v1.10 or earlier) — from v1.11.0 onward, the app clears its own quarantine flag automatically after every in-app update.

Windows

1. Run the *-setup.exe installer
2. Windows SmartScreen will show “Windows protected your PC” — click More info, then Run anyway
3. Follow the installer prompts

Linux

• AppImage (portable, no install):

  chmod +x Udaan_*_amd64.AppImage
  ./Udaan_*_amd64.AppImage

• .deb (Debian/Ubuntu):

  sudo dpkg -i Udaan_*_amd64.deb
