Beta builds are not signed or notarized yet
While Nora is in beta, release installers and apps are not code signed for Windows, are not signed with an Apple Developer ID, and are not notarized for macOS. Your operating system may show warnings or try to block installation and first launch. The files linked from the official download page are the real releases; these prompts are normal until we ship properly signed and notarized builds.
Bypass security prompts only for installers and apps you obtained from the official Nora download page or the project’s published release assets. If you are unsure about a file’s origin, do not override the warning.
macOS (Gatekeeper)
Gatekeeper may say the app or installer cannot be opened because the developer cannot be verified. After copying Nora to Applications (if you used a disk image), Control-click or right-click the Nora app in Finder, choose Open, then click Open in the dialog. Alternatively, open System Settings → Privacy & Security, scroll to the Security section, and use Open Anyway next to the message about Nora. You can repeat Open via the context menu if the first attempt still blocks.
Windows (SmartScreen)
SmartScreen may show that Windows protected your PC because the app or installer is from an unknown publisher. Click More info, then Run anyway. The exact labels can vary slightly between Windows versions, but the pattern is always to reveal the advanced option and confirm that you still want to run the file.
Linux
Linux desktops usually do not apply the same kind of publisher check as macOS and Windows. If you use an AppImage, you may need to mark it executable (for example `chmod +x` on the file) before it will run. If your distribution or security tooling blocks the binary, follow that environment’s documentation for running locally installed applications.
