If your computer blocks the first launch Common, and a one-time fix. The download is fine.
macOS and Windows both ask you to confirm the first time you open an app downloaded from outside their own stores, and the wording can sound alarming. It takes a few seconds. Pick your system below.
macOS 15 Sequoia or later Control-click no longer works on these versions
- Double-click NovelOS. macOS blocks it — that is expected.
- Open System Settings, then Privacy & Security.
- Scroll to Security. "NovelOS was blocked" appears with an Open Anyway button.
- Click Open Anyway, then confirm with your password or Touch ID.
macOS 14 Sonoma or earlier
- Right-click (or Control-click) NovelOS in Applications.
- Choose Open from the menu.
- Click Open in the dialog that appears.
Windows
- Windows may show "Windows protected your PC".
- Click More info, then Run anyway.
Mac: still blocked after the steps above Clears the quarantine flag for NovelOS only
- Open the Terminal app (Applications, then Utilities).
- Type xattr -dr com.apple.quarantine followed by a space.
- Drag NovelOS from your Applications folder into the Terminal window. The path fills itself in.
- Press Enter, then try opening NovelOS again.
xattr -dr com.apple.quarantine /Applications/NovelOS.appIf it answers "Operation not permitted", put sudo in front and run it again. It will ask for your Mac password, which is not shown as you type.

What's new
- Added: Try NovelOS free for 7 days on Windows and macOS. Choose Try free for 7 days when NovelOS opens and enter your email; no card is needed. The trial includes 1 project, 5 chapters, 3 characters, 2 world entries, 2 lore entries, 1 plot, 2 scenes and 1 Spark board, and exports to PDF. AI features and .novelos project files come with a license. Activate a license at any time, from the trial badge in the top bar, and everything you wrote stays where it is.
- Improved: NovelOS opens faster. It now loads about a quarter of the code it used to at launch: exports, AI features, audiobook export and languages other than English load the first time you use them.
- Improved: Switching between Overview, Spark, Cast & World, Blueprint and Manuscript shows the new page in about half the time.
- Improved: Large books stay responsive while you write and plan. Typing no longer redraws the navigation bar, and changing one card on a plot board, Spark board or family tree no longer redraws every other card.
- Improved: Phone app: the studio opens much faster, about two and a half times faster the first time on a typical phone connection, and it no longer downloads the whole studio again every time you open it. The full studio still works offline.
