Vellum 4.1.7 on Mac

Vellum runs on any Mac with macOS 11 or later, so both Intel models and Apple Silicon machines are covered. That includes the M2 Air I use for DJ work and, when I need a break from beats, for laying out my own music-related writing.

Vellum is for anyone who wants to turn a manuscript into a proper ebook or print edition without fighting layout details. You import your text, and the app builds a title page, table of contents, and lets you add copyright-page content inside. Pick a trim size and Vellum adjusts margins, page numbers, headers, and footers automatically. It can generate print and ebook editions together, with instant previews as you edit — on screen for multiple devices and for print. The ebooks come out ready for Kindle, Kobo, Apple Books, and other platforms. It's a practical tool for self-publishers, authors, or anyone who needs a clean finished file.

Installing Vellum is straightforward. After mounting the downloaded disk image, move the application into the Applications folder alias, then launch it from Launchpad once the copying is done. The app is native to macOS and feels right at home on the Mac, whether you're on an Intel machine or Apple Silicon.

Pulling your manuscript from Word or Scrivener

Vellum doesn't live in isolation. You'll likely pull your manuscript from a word processor — maybe Word, Google Docs, or Scrivener — and Vellum handles the import well, creating a title page and table of contents from your document's structure. If you're like me and write in Markdown in iA Writer or Ulysses, you can export as plain text or RTF and bring it in. The app then applies your chosen style to every chapter, including any you add later.

For cover images, Vellum works with standard image formats you'd have on your Mac. Drag a cover into the project and the app places it where it belongs. The resulting ebook files sit on your drive like any other file, ready to upload to Amazon KDP, Kobo Writing Life, or Apple Books via your browser.

macOS features I've found useful: use the Mac's built-in screenshot tool (Cmd+Shift+4) to grab previews for sharing with collaborators. Vellum's instant preview updates as you edit, so you can snap a quick look at how a change reads on a simulated Kindle screen. The app also respects macOS's window management — I often have Vellum on one half of my screen and a browser with platform guidelines on the other.

Importing a short manuscript to test styles

Start by importing a short manuscript — a few chapters at most. This lets you see how Vellum handles headings, chapter breaks, and paragraph styles without committing to a full book. After import, explore the style options. The app applies a consistent style across all chapters, so tweak one heading and the rest follow.

Set your trim size early. Vellum adjusts margins, page numbers, headers, and footers as soon as you pick it. Changing the trim size later is possible, but you'll save time by deciding before you fine-tune chapter openings or section breaks.

Add copyright-page content inside the app — it's something many first-timers forget until the final pass. Then generate both ebook and print editions together to see how they differ. The preview for multiple devices (Kindle, Kobo, Apple Books) shows you how your text flows on each screen, while the print preview catches page issues before you export.

Requires macOS 11 or later

Vellum requires macOS 11 or later. That means it runs on anything from Big Sur upwards, covering Intel 64-bit and Apple Silicon Macs equally. The app is native to macOS, so it responds to standard gestures like trackpad scrolling, window resizing, and the Mac's font rendering. The interface is in English, and there's no separate plugin or runtime to install — just the app itself.

The disk image you mount is self-contained. After dragging the app to your Applications folder, you can eject and trash the image. Vellum doesn't scatter files across your system; it stays where you put it. Expect the app to launch from Launchpad or the Applications folder like any other Mac application.

Inconsistent heading styles cause formatting issues

A common one is importing a manuscript with inconsistent heading styles. If your Word document uses Heading 1 for some chapter titles and just bold text for others, Vellum doesn't read minds — it treats them differently. Clean up your source document first, or use Vellum's style tools after import to align everything.

Some users skip the device preview and only check the editor view. The editor shows how the content is structured, but the preview shows what a reader actually sees on a Kindle or Kobo. Always preview before generating your final file. Another misstep: not reviewing the generated ebook on an actual device or in a reading app. A quick side‑load onto your phone or tablet catches formatting issues the preview might miss.

Forgetting to set the trim size before making layout tweaks is another time‑waster. Vellum adjusts margins, page numbers, headers, and footers based on trim size, so making those adjustments first means you won't redo chapter spacing later. And if you're creating a boxed set from multiple books, don't try to merge separate projects manually — Vellum handles boxed sets within the app, using the styles you've already set for each book.

Finally, a few people treat Vellum like a word processor and try to edit paragraph by paragraph inside it. It's not that. Vellum applies style to structure: you set the rules (first‑line indent, space after paragraphs, font) and the app follows them across the whole book. Fighting that approach leads to frustration. Trust the system, and you'll get a consistent book out the other end.
