All downloads

Windows

Windows 10 & 11 · 64-bit

Download for Windows 64-bit · setup

For IT and silent installs: the .msi

On first run, click “More info → Run anyway” if Windows shows a SmartScreen notice.

macOS

Apple Silicon (M1/2/3/4/…) & Intel · macOS 12+

Apple Silicon M1/2/3/4/… · arm64 · .dmg Intel Mac x86_64 · .dmg

Give it Full Disk Access on first run, or it cannot read Documents and Desktop — the app links straight to the setting. Not sure which build? Apple menu → About This Mac: an “Apple M-series” chip means Apple Silicon. If the app bounces once and never opens, you have the other build — these are separate binaries, so the wrong one cannot run, even through Rosetta. Download the other one and drag it over.

Linux

Ubuntu · Linux Mint · Pop!_OS · 64-bit

Ubuntu 24.04 / Mint 22 also Pop!_OS 24.04 Ubuntu 22.04 / Mint 21

Not sure which one? Pick the first (Ubuntu 24.04 / Mint 22).

AI agents

BACK comes with an MCP server and a command line, so AI apps on your computer — Claude, Cursor, VS Code, Codex, Gemini CLI — can use it the way you do, and install its updates. Connect one in Settings > AI agents; with All MareArts apps picked, one connection reaches every MareArts app on your computer. Signing in, Remote access and the AI settings always wait for your Yes in the BACK window. How to connect →

How to install

  1. Download the file for your system above.
  2. Install it:
    • Linux — double-click the .deb and press Install.
    • macOS — open the .dmg, drag the app to Applications, and grant Full Disk Access when it asks. Without it macOS hides Documents, Desktop and Downloads from the app.
    • Windows — run the downloaded installer (one window: Install, then Launch) (if a SmartScreen notice appears, click “More info → Run anyway”).
  3. Open MareArts Backup and use your purchase email and the 16-character signature from your purchase email, or a licence key. The website uses a separate 6-digit sign-in code. Already running another MareArts app? There is nothing to sign in to.
  4. Linux: updates arrive automatically through your system updates. macOS & Windows: the app updates itself — you’ll get a prompt when a new version is ready.
