Common Questions
What Markdown features does Mandrill support?
Mandrill supports GitHub-flavored Markdown (GFM) including headings, bold and italic text, blockquotes, ordered and unordered lists, task lists, tables, fenced code blocks with syntax highlighting, inline code, and horizontal rules.
Does Mandrill work without an internet connection?
Yes, completely. Mandrill is 100% offline. It makes no network requests and has no dependency on any external service. It will work anywhere your Mac works.
Can I edit Markdown files in Mandrill?
Not yet. Mandrill is still a reader, not an editor. It's designed to render Markdown cleanly. For editing, use any text editor you prefer (VS Code, Typora, iA Writer, etc.) and open the file in Mandrill to preview it.
What macOS version is required?
Mandrill requires macOS 13 Ventura or later. It runs natively on both Apple Silicon and Intel Macs.
Is Mandrill really free? Any hidden costs?
Completely free. No in-app purchases, no subscription, no premium tier. Just download it and use it.
How do I open a file in Mandrill?
You can drag any .md file directly onto the Mandrill window or dock icon, or use File → Open to browse for a file using the standard macOS file picker.
