Vellum 4.2.0 — Mac build

Vellum 4.1.5 for Mac starts with a feature most writers only discover after reformatting a whole book by hand: automatic page and margin adjustments. Pick a trim size and the app recalculates margins, page numbers, headers, and footers instantly. No manual pass.

Standout features and what they do

Manuscript import — Brings in your text and generates a title page and table of contents automatically.

Ebook generation — Produces files for Kindle, Kobo, Apple Books, and other platforms directly from your manuscript or a blank start.

Boxed set creation — Combines multiple books into a single volume for series collections.

Print edition layout — Applies consistent typography and handles widows and spread balancing.

Regeneration workflow — After any edit, regenerate updated ebook files without rebuilding the entire project.

Vellum runs on both Apple silicon and Intel Macs, and needs macOS 11 or later. If you're hunting for a vellum torrent, this version is the one to get.

Will it run on my Intel Mac

Will it run on my Intel Mac? Yes. Vellum 4.1.5 supports both Apple silicon and Intel 64-bit Macs, so the architecture check is not something you need to worry about. The only hard requirement is macOS 11 or later.

Do I need to convert my manuscript first? No. The app imports a manuscript and handles the conversion internally. It creates the title page and table of contents as part of the import step. What you feed it is what gets formatted; you are not expected to prep anything in another tool.

Can I work on a print edition and an ebook at the same time? Yes. Vellum generates print and ebook editions together. You set the trim size for print, and the ebook output is derived from the same project. That is the core workflow, not an add-on.

What happens when I add a chapter later? The style you selected applies automatically. Newly added chapters get the same treatment as the existing ones. You do not need to go back and reformat anything.

Is the interface in English only? Yes. The app's interface language is English. If you work in another language, the text you write stays as-is; the menus and panels are English.

What operating systems are covered? macOS 11 and later, on both processor types. That covers a wide range of Macs, including older Intel models that have not been updated to the newest macOS versions.

A scenario: the self-publishing team with a series

Consider a small team that publishes a three-book fantasy series. They keep each book as a separate manuscript file. In Vellum, they create a project for each book, import the manuscripts, and select a consistent style across all three. The print editions get the same trim size and the ebook output goes to Kindle, Kobo, and Apple Books. When they want a boxed set, they create a new project and combine the three books into one volume. The margins, page numbers, and headers are recalculated automatically for the combined book, so the team does not spend an afternoon fixing page ranges by hand. When a typo surfaces in book two, they fix it in the original project and regenerate the ebook files. The boxed set gets regenerated too, from the same updated source.

The key point is that the team works with one project per book, not one giant file. That keeps regeneration fast and avoids the mess of trying to format a trilogy as a single document.

Preview mismatches the final output

• The preview does not match the final output. Check which device preview you are looking at. Vellum provides previews for multiple devices and for print output. If you are looking at a phone preview but testing on a tablet, the rendering will differ. Switch the preview target to match your test device.
• The table of contents looks wrong after editing. The table of contents is generated from your chapter headings. If you changed a heading's text, regenerate the ebook files. The table of contents updates from the current state of the project, not from the original import.
• Print margins feel off for a specific trim size. The automatic adjustment selects margins based on the trim size you picked. If you need different margins, adjust them after the selection. The app recalculates page numbers, headers, and footers to fit the new margins.
• Copyright page content is missing. Add it inside the app. Vellum lets you include copyright-page content directly in the project, so you do not need to insert it into the manuscript file beforehand.
• The ebook file is outdated after a small change. Regenerate the files. The regeneration workflow updates the output from the current project state, so there is no need to rebuild anything from scratch.

A workflow: formatting a manuscript for print and ebook

Start with a finished manuscript file. Open Vellum and create a new project. Import the manuscript. The app generates a title page and a table of contents from the document's structure. If you have a specific copyright page, add the content inside the app rather than editing the manuscript file.

Select a style for the book. The style applies to every chapter, including any you add later. If you are producing a print edition, pick a trim size. The app adjusts margins, page numbers, headers, and footers automatically. Look at the print preview to check widows and spread balancing; if you see any awkward breaks, the app handles the balancing, but a quick visual pass catches anything unusual.

Generate the ebook output for Kindle, Kobo, and Apple Books. Keep the project file. When you edit the manuscript later, reopen the project, make the changes, and regenerate the ebook files. For a print edition, regenerate that output the same way. If you have a series, create a boxed set project and combine the individual books. The combined volume gets the same automatic formatting treatment.
