You can take a book from an empty Mac workspace to a five-chapter EPUB in one continuous lifecycle: write the chapters, choose five navigation entries, assign a cover, add the colophon, export, and inspect the package. The easiest way to keep moving is to define what “done” means at each milestone before you start writing.
This is a blank-workspace-to-output guide. It is not about consolidating manuscripts that already live in several other apps.
Define the finish line for a five-chapter book
Use five simple chapter topics: writing on Mac, separating chapters, choosing a cover, exporting EPUB, and checking the result. Before drafting, write down these acceptance conditions:
- five source files,
C01.mdthroughC05.md; - one navigation heading from each chapter;
- one selected cover;
- one colophon with author and publication details; and
- one exported EPUB whose order and missing assets have been checked.
You do not need to draft the chapters in numerical order. You do need one current source for each chapter so that later corrections have an obvious destination.
Grow the draft one chapter at a time
Create C01.md, write its heading and body, then add C02.md. Continue until all five files exist. A single large document can also work, but separate chapter files make the relationship between a navigation entry and its source easier to see.
Replace temporary labels such as “Chapter 2” with reader-facing headings before export. The heading “Separating Chapters” tells a reader more than a number alone and gives you a useful navigation label.
Rune Studio’s published documentation covers long-form editing, manuscript organization, navigation, cover, colophon, and EPUB 3 output. The observed example below used horizontal text.
Prepare five navigation entries, a cover, and a colophon
Count the inputs before opening the export flow: five chapter files, five intended navigation entries, one cover, and one colophon. In the observed sample, C01.md through C05.md were selected in numerical order and all five were included in navigation.
The cover assignment read back as images/studio-076-01.png. There were no inline images, so the expected package image count was one—the cover. Keeping that expectation in mind makes a count of zero or two immediately suspicious.
EPUB 3 separates metadata, packaged resources, reading order, and navigation. The EPUB 3.3 specification is the general reference for those roles; product behavior should be considered separately.
Use the EPUB Wizard as a reconciliation point
While preparing the EPUB output, compare the current choices with the finish line: five selected chapters, five navigation entries, and the chosen cover. Running the export is not a substitute for confirming the selected files and their order.
After export, inspect reading order, navigation, packaged images, and missing assets. The five-chapter sample produced a spine containing cover, title, navigation, five content documents, and colophon. It had navigation and NCX, one packaged image, no missing images, and valid=true.
Run one correction through the lifecycle
Suppose the first result reveals that the Chapter 4 heading should be “Exporting to EPUB” rather than “Make an EPUB.” Return that correction to C04.md, not just to the visible navigation and not to the exported package. Rebuild the same five chapters and confirm the corrected entry.
Choosing the correction destination is an editorial rule. The observed run did not show Rune Studio interpreting a correction sheet and selecting C04.md automatically. Keep a small record with the correction, its source destination, and the result after rebuilding.
What was observed—and what remains yours to test
The controlled run established a horizontal five-source-chapter export with all five chapters selected for navigation. Local inspection found navigation, NCX, one packaged cover, no missing images, and valid=true.
That status is a local structural result. It is not retailer acceptance, a promise of identical rendering in every reader, or a measurement of drafting speed. Test those conditions with your own manuscript and target reading systems.
Conclusion: connect the milestones into one loop
For ebook creation on Mac from draft to EPUB output, add one chapter source at a time, reconcile five chapter and navigation entries, assign the cover and colophon, export, and route every correction back to its source before rebuilding.
Try the complete loop with a short five-chapter practice book first. Current Mac features and download options are available on the Rune Studio website.
