First open on Mac

macOS may say the app can’t be verified. That’s normal for small open-source apps that aren’t notarized. You can still run it:

  1. Unzip and move WriteAI to Applications.
  2. Control-click the app → Open → then click Open in the dialog. (Use Open—not double-click—the first time.)
  3. If it was blocked already: System Settings → Privacy & Security → scroll to Security and choose Open Anyway for WriteAI.
