Antivirus False Positive

Some antivirus scanners (notably Microsoft Defender's Wacatac.B!ml ML detector) may flag the DMG. This is a known false positive affecting ad-hoc signed macOS apps and DMG files. The full source code is open and auditable — no malicious code, no network connections, no telemetry. You can verify at VirusTotal.
