FAQ
Why no macOS (.dmg) yet?
macOS requires all distributed apps to be signed and notarized by an Apple Developer account ($99/year). Unsigned .dmg files are blocked by Gatekeeper on macOS 13+. macOS support is planned once code signing is in place.
My antivirus flagged the installer — is it safe?
This app is not yet code-signed. Some heuristic scanners may flag unsigned open-source binaries as suspicious. We are currently applying for code signing through SignPath Foundation — thank SignPath Foundation for supporting open source projects like ours. Windows Defender and ClamAV both pass. Source code is fully public — verify it yourself or build from source.
