6 Crucial Facts About the Notepad++ Mac App Trademark Dispute

When a popular Windows-only tool suddenly appears on Mac, it can spark excitement—or controversy. That's exactly what happened with Notepad++, the beloved open-source text and code editor. A macOS version surfaced, but instead of celebration, it ignited a trademark clash. Here's everything you need to know about this unfolding story.

1. The Unauthorized Notepad++ Mac App

In early 2025, Mac users discovered an app named Notepad++ (Unofficial) on their desktops, seemingly offering the same lightweight code editing experience. The app, developed by Andrey Letov, was distributed through a dedicated website and quickly gained traction. However, it was not created by the official Notepad++ team. Letov built it as a personal port without any license or permission from the project's founder, Don Ho. This immediately raised red flags about intellectual property and user trust.

2. Don Ho's Strong Condemnation

Don Ho, the original creator of Notepad++, publicly denounced the macOS version in a blog post. He stated that the app is not authorized, not endorsed, and not affiliated with the official project. Ho called it misleading, inappropriate, and frankly disrespectful to both the project and its users. He emphasized that Notepad++ has never released a macOS version, and urged users to avoid downloading the fake app. His strong language underscored the seriousness of the trademark violation.

3. Trademark and Branding Issues

The core problem is trademark infringement. Notepad++ is a registered trademark owned by Don Ho. By using the name and logo without permission, the macOS port violates that trademark. This isn't just about legal technicalities—it confuses users into believing the app is official. Such confusion can harm the reputation of Notepad++ if the port introduces bugs or security issues. Ho's response was necessary to protect the brand and maintain user trust.

4. Andrey Letov's Rebranding Plan

In a constructive turn, developer Andrey Letov agreed to rebrand the macOS version. He announced that upcoming version 1.0.6 will include a new logo, a refined name, and likely a new domain. Letov stated he wants the Mac app to stand on its own while respecting its lineage. He promised a seamless transition for existing users, ensuring continuity. This cooperative approach aims to resolve the trademark issue without legal battles, turning a conflict into an opportunity for a distinct Mac-native editor.

5. What This Means for Mac Users

For Mac users longing for a native Notepad++ experience, the situation is mixed. The unofficial app will survive but under a different identity. Users who already installed it will automatically receive the rebranded version via updates. However, the app may lose some Notepad++-specific features or plugins due to platform differences. Don Ho has not announced an official macOS port, so those seeking a similar tool should look at alternatives like TextMate or VS Code. Always verify app origins to avoid security risks.

6. The Future of Notepad++ on macOS

This dispute highlights the demand for a macOS version of Notepad++, but Don Ho has given no indication of plans to develop one. The rebranded app might fill the void if it evolves into a respected independent project. Meanwhile, the trademark standoff serves as a reminder of the importance of respecting intellectual property in open-source communities. As Andrey Letov finalizes the new branding, the two sides may find peaceful coexistence—provided clear boundaries are respected.

This controversy shows that even open-source projects need protection from unauthorized clones. While the Mac app continues under a new name, the original Notepad++ remains Windows-only. For now, users should stay informed and only download software from verified sources.
