Download: UpDown_2.0.3_aarch64.dmg (Apple Silicon)

UpDown v2.0.2

What's new

Quick Look — fixed double list markers

The Quick Look preview extension now uses WKWebView (full WebKit) instead of the legacy NSAttributedString(html:) renderer. This fixes the long-standing bug where bullet and numbered list items showed duplicate markers (• • and 1 1), and brings Quick Look rendering in line with the in-app preview.

Quick Look — empty bottom panel removed

The metadata panel at the bottom of Quick Look previews no longer shows an empty space when a file has no YAML frontmatter block.

Landing page

A new static landing page is now live at neshkoli.github.io/updown — features, install instructions, and download links.

⚠️ Gatekeeper — "damaged and can't be opened"

Because the app is not yet notarized by Apple, macOS Ventura / Sonoma / Sequoia will show this error when you first try to open the downloaded app. To fix it, open Terminal and run:

xattr -d com.apple.quarantine /Applications/UpDown.app

• Markdown formatting toolbar — Bold, Italic, H1–H3, Link, Image, Lists, Blockquote, Code Block, HR, Table
• Live preview powered by markdown-it
• Bidirectional text — auto-detects Hebrew vs Latin dominant paragraphs
• Folder panel — browsable sidebar with navigation, resize, and persistence
• Drag-and-drop file opening
• Autosave with dirty tracking (window title shows *)
• 112 unit tests (Vitest + happy-dom)
