Opening documents
Supports .md, .markdown, .mdown, and .txt. If a file fails to open, check the extension and macOS file permissions.
SUPPORT
Siftmd Support
If you run into trouble opening files, exporting documents, rendering diagrams, or installing the App Store build, reach out directly. Include your macOS version, Siftmd version, reproduction steps, and screenshots when possible.
Code, diagrams, and math
Siftmd bundles Markdown parsing, syntax highlighting, KaTeX, and Mermaid rendering. For complex diagrams, verify the fenced code block language.
Exporting PDF / HTML / Handoff
Exports are saved to the location you choose. If saving fails, check folder permissions or disk space.
Refresh and updates
If the interface looks stale, reopen the document or restart the app. Once the App Store build ships, updates will arrive through the system channel.

macOS version
Siftmd version or install source
