1.13 · build 30 · Oct 30, 2026 · current
Release day: your licence, About the author, and fixes
- Paste your licence key on first run. The paywall matches the site: pay what you want until 31 December 2026, then $169 once.
- About the author: your bio and photo close the print book and the ebook.
- Fixed: chapters now always open on a right-hand page, and the page count, gutter and spine match the PDF.
- AI art made in the cover Studio now counts in the KDP sheet's AI image answer.
- Plan outline, Rewrite, adding to the Bible, Deactivate on this Mac and other buttons that ask a question now work on every Mac.
- 8.25 × 11 in no longer gets a wrong cover warning.
1.12 · build 26 · Oct 19, 2026
Nonfiction, and a new cover Studio
- Studio is now the cover editor, with nine layouts previewed from your own title and colours.
- AI cover art for the front, or one wide picture across the whole wrap, enlarged for 300 DPI print.
- Restyle the whole cover in one click: ten palettes and nine type pairs.
- Nonfiction is set up as nonfiction. Pick the kind of book first, and your notes are sorted into your call and research.
- A nonfiction pitch with a thesis, a research plan and facts to check. Nothing is made up: unsure facts are marked, and the KDP pack waits until they are checked.
- Decide for me, or Not sure yet, on every setup question.
0.11.0 · build 24 · Oct 2, 2026
Your length and your rules
- Set the length in pages or words, and your writing rules, before the AI writes: no em dashes, UK or US spelling, no AI-sounding phrases.
- Cover art with AI in the Cover tab. Describe it or let it suggest one, pick from four, and it is enlarged to print size with bleed.
- A manuscript check before the KDP pack catches AI leftovers, placeholders and cut-off chapters.
- Chapter openings your way: big numbers, small titles, ornaments or drop caps.
- Fixed: after an AI writing run, the editor could save an older copy over the new chapters.

“Author Magic” Not Opened, or “Apple could not verify” it
This build isn't notarised by Apple yet, so macOS asks once. Open System Settings › Privacy & Security, scroll to Security and click Open Anyway, then confirm with your password. On macOS 14 and earlier, Control-click the app in Applications and choose Open instead. You do this once per version.
I'd rather use Terminal
Run this, then open the app as usual: xattr -dr com.apple.quarantine "/Applications/Author Magic.app"
macOS says the app is damaged
That message comes from the same check. Move the app to Applications, run the Terminal line above, and open it again. If it still won't open, contact support from this site and tell us your macOS version.
Does it run on an Intel Mac or on Windows?
Not yet. Author Magic needs a Mac with Apple silicon (M1 or later). If you'd like a Windows or web version, open this page on that computer and tell us which.
How do I update?
Quit Author Magic, download the new version here, and drag it to Applications to replace the old copy. Your books and settings are kept.
What do I get?
Whatever you pay, $1 or more: the full licence for every book (normally $169), every 1.x update, and the Mac app. Your licence key and the download are on the page right after checkout, and in your email. Refund within 7 days if it won't work on your Mac.
How do I check the download?
In Terminal, run shasum -a 256 ~/Downloads/Author-Magic-1.13.dmg and compare it with the SHA-256 shown on this page.
