Use the official downloads
Install Nora only from the official download page or the project’s published release assets. Windows installers are not code signed yet, so Windows may show an unknown publisher warning during installation or first launch.
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
Download the macOS disk image, open it, and copy Nora to Applications. Open Nora from Applications after installation.
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.
