What is MacDown 3000?
MacDown 3000 is a native macOS Markdown editor for writing and previewing formatted text documents. It is designed for people who want a focused desktop tool for notes, documentation, blog drafts, README files, and other plain-text writing workflows.

It also supports syntax highlighting for code blocks, multiple preview themes, and export or print workflows for sharing finished content.

Safety overview
Status: Safe
MacDown 3000 is a legitimate desktop writing app for Markdown editing on macOS. Its normal behavior is local document editing, preview rendering, and opening Markdown files, which are ordinary actions for this type of app. As with any document editor, use normal care when opening files from untrusted sources and review export output before sharing it.
Recommendation: Keep MacDown 3000 if you use Markdown for notes, documentation, or writing on your Mac. Remove it if you no longer need a dedicated Markdown editor; doing so may also remove your preferred app association for .md files and any app-specific settings.
