The app · Mac and Windows
Brobot, in a window of his own.
One app that starts your world and your teammate, and shows what he is doing: his health, a live map, his bags, the chat and autopilot. Each download opens here once it has been tested on its own system.
Version 2.1.0 · Minecraft Java 1.21.11
Pick your computer.
Each file below has its SHA-256 checksum, so once downloads open you can confirm you got exactly what was built.
On a Mac, one line does it
Open Terminal (press ⌘ Space, type Terminal, press Return), paste this and press Return. It picks the right file for your Mac, checks its checksum, puts Brobot in Applications and opens it. The app is not signed with Apple yet, so a copy downloaded in a browser would be blocked; installing this way avoids that.
curl -fsSL https://trybrobot.com/install-app.sh | shOn Windows
Run the installer. If Windows says it protected your PC, click More info, then Run anyway. That warning appears because the app is not code signed yet. If Windows asks whether Brobot may use your network, allow it on private networks: that is how he spots worlds opened to LAN.
Downloads are not open yet. Until they are, the one-line install on Get started is the way in, and it is the same Brobot.
Three different things
Checksum, download link, code signature.
They are easy to mix up, and only the last one decides whether your computer trusts the app.
Checksum
A fingerprint of the file. If yours matches the one on this page, the file arrived exactly as it was built. It does not say who built it.
Download link
Where the file lives. Some links are signed: they expire and only work for whoever was given them. That controls who can fetch the file, not whether your computer trusts it.
Code signature
Apple's Developer ID with notarisation on a Mac, Authenticode on Windows. This is how macOS and Windows check who published an app. Without it a Mac refuses to open a downloaded app and Windows shows a warning first.
Questions
Before you ask.
Why does the Mac app install with one line?
A Mac only opens a downloaded app without a warning when it is signed with a paid Apple Developer ID, and ours is on the way. Until then the one-line install puts exactly the same app in Applications, with no warning. The Windows installer is not code signed yet either, so Windows shows a SmartScreen warning first: click More info, then Run anyway.
Can Brobot join a world I opened to LAN?
Usually not. A world opened to LAN checks every player's Microsoft sign-in, and Brobot has no Minecraft account, so Minecraft turns him away. He runs his own world instead: start him, then in Minecraft choose Multiplayer, then Direct Connection, type localhost and press Join Server. He can join servers that do not check sign-ins.
How do I check a checksum?
On a Mac, open Terminal and run shasum -a 256 followed by the file. On Windows, open PowerShell and run Get-FileHash followed by the file. The long code it prints should match the one on this page exactly.
Where does the app keep my world?
In a folder called Brobot in your home folder. Updating the app never touches your world, your settings or what he remembers.
