Common questions

How do I make QuickMark the default app for .md files?

In Finder, right-click any .md file → Get Info → Open with: select QuickMark → Change All…

Quick Look (Space) shows the system text preview, not QuickMark.

Another Quick Look extension (e.g. QLMarkdown) is winning the priority race. Open System Settings → General → Login Items & Extensions → Quick Look, uncheck the competing extension, and try again.

Auto-reload doesn’t work with Vim.

Vim writes files atomically (rename instead of in-place write). QuickMark handles both in-place writes (VS Code, Sublime) and atomic rename saves (Vim, Helix) — no configuration needed.

Can I configure the default view mode, theme, or font size?

Yes — open QuickMark → Settings… (⌘,). You can set the default view mode (Editor / Split / Preview), preview font size, app theme, and code-block syntax theme. QuickMark also follows your system Light / Dark mode automatically.

Can I edit files in QuickMark?

Editing requires QuickMark Pro ($9.99 one-time). With Pro, Editor (⌘1) and Split (⌘2) modes let you write directly in QuickMark with monospace font, undo, and find; save with ⌘S. The free version stays a full-featured viewer — open and read any .md file, Quick Look with Space, and even auto-reload from another editor.

What features require QuickMark Pro?

Pro unlocks editing (Editor and Split modes), Print (⌘P), Export as PDF (⇧⌘E), and on iPhone / iPad, the "Save to QuickMark" Share Sheet action. Everything else — Quick Look preview, viewer mode, syntax highlighting, KaTeX math, Mermaid diagrams, Find-in-page, outline sidebar, auto-reload, code themes, and settings — is free forever.

How do I upgrade to QuickMark Pro?

Open QuickMark and click any locked feature (the Editor or Split toolbar buttons, or File → Print / Export as PDF). A purchase sheet appears with a single Buy — $9.99 button. The transaction is handled by Apple via the App Store — QuickMark never sees your payment details.

One-time purchase or subscription?

One-time. QuickMark Pro is $9.99 once and yours forever — no monthly fee, no annual renewal, no surprise charges.

Does QuickMark Pro work on iPhone and iPad?

Yes. QuickMark Pro is a Universal Purchase — buy once on Mac and it unlocks automatically on iPhone and iPad signed in to the same Apple ID. (The iOS version is coming soon.)

Can I share QuickMark Pro with my family?

Yes — QuickMark Pro supports Family Sharing. Enable Family Sharing on your Apple ID and up to five family members get Pro automatically.

How do I restore my purchase on a new Mac or after reinstalling?

Open QuickMark, trigger the purchase sheet (click any locked feature), then tap Restore Purchases. Sign in to the same Apple ID you originally bought with — Pro unlocks immediately.

Which markdown features are supported?

Full GitHub Flavored Markdown (tables, task lists, footnotes, strikethrough, auto-links), KaTeX math (inline and display), and Mermaid diagrams. Code fences are syntax-highlighted via Prism with support for 30+ languages including TypeScript, Swift, Python, Rust, Go, Bash, SQL, JSON, YAML, and more. Click any code block to copy.

How does printing / Export as PDF work?

⌘P prints the rendered preview using the system print dialog. ⇧⌘E exports the rendered document straight to a PDF file. Both follow the current theme and font size. Print and Export as PDF require QuickMark Pro.
