Windows

Format	Description
EXE Installer	Recommended, double-click to install

Both dmg and app.tar.gz in current releases are not Apple-signed/notarized yet, so macOS may show “app is damaged” or “developer cannot be verified”.

• dmg: open the DMG first, drag Sea Lantern.app into /Applications, then run:

xattr -dr com.apple.quarantine /Applications/Sea\ Lantern.app

• app.tar.gz: extract first, then run this in the extracted current directory:

xattr -dr com.apple.quarantine ./Sea\ Lantern.app

If it is still blocked, go to “System Settings -> Privacy & Security” and click “Open Anyway”, or right-click the app and choose “Open”.

DEB	Debian / Ubuntu
DEB (ARM64)	Debian / Ubuntu ARM64
RPM	Fedora / RHEL (x86_64)
