Notepad++ for Mac (Unofficial): Why We're Telling You to Steer Clear

TL;DR: This is a trademark hijacking attempt that impersonates the original developer to distribute unverified binaries via a deceptive domain.

The red flags:
- The official creator, Don Ho, has denounced the project as a fake and issued a trademark infringement notice (Official News, 2026-05-01).
- The site creators hijacked the official author’s identity by copying his biography to their "Author" page to appear legitimate (GitHub Issue #17982).
- Following the Lotus Blossom supply chain attack on the real Notepad++ infrastructure in February 2026, these unauthorised binaries pose a severe malware risk (Official Blog).

What we found:
The site notepad-plus-plus-mac.org surfaced on April 29, 2026, claiming to offer a native Cocoa UI built via "multi-agent AI development workflows" (MacRumors Forums, 2026). While the site looks professional and uses an AI-generated variant of the official logo, the source code for the wrapper remains unverified (GitHub Issue #17982). Major tech outlets initially fell for the claim before issuing urgent warnings when the identity theft was discovered (MacRumors, May 1, 2026). In an era where GPT-5 and Claude 4.5 can port Win32 calls to Cocoa in seconds, the technical achievement is no guarantee of security. We don't know the true motives of the purported developer, Andrey Letov, but stealing a developer's bio is rarely the hallmark of a benign project.

Our advice: Avoid this site. There is no official Notepad++ for Mac, and using an editor with a hijacked identity is a fast track to a compromised production environment.
