Computers
This computer
Let a supported agent control the local desktop through the bundled CUA boundary.
Local control is off by default. The Electron main process owns the bundled CUA driver lifecycle so operating-system permissions are attributed to Brainwrite rather than a background helper.
macOS
The packaged app can request Accessibility and Screen Recording permission. After granting either permission, restart the control session when prompted so macOS applies the new grant.
Ubuntu
Controlling the computer Brainwrite runs on is available on macOS. On Ubuntu it is switched off until it meets the same input-safety bar; bots there can still use a Local VM, a Boat cloud computer or your own VPS.
Safety model
- Enabling local control globally does not assign it to a bot.
- Choose This computer for each bot that should receive the capability.
- Risky actions still surface through the approval flow.
- Missing permissions, unexpected binaries, unsupported desktop sessions, and failed health checks fail closed.
