Before you download
What you need
| Windows | 64-bit. Choose the installer, or the portable zip that runs without installing. |
|---|---|
| Linux | 64-bit Intel or AMD, or ARM64 (for example a Raspberry Pi 4 or 5). Choose an AppImage, a .deb, an .rpm or a tar.gz archive. |
| Mac | A Mac with an Apple chip (M1 or later). Choose the installer (.dmg). It is signed and checked by Apple. |
| Graphics | Annora uses your graphics card when it finds one, and your processor when it does not. |
These apps are new and the Windows installers are not signed yet, so Windows may say “Windows protected your PC”. Choose More info, then Run anyway. Every file lists a SHA-256 checksum so you can check it.
