01What can it help you accomplish?
Control Chromium and macOS windows from a DSH agent without taking over the user's pointer
Bounded text observations plus browser or desktop actions using semantic refs, roles, names, values, state, and geometry
DSH users on macOS who need targeted browser automation or background desktop control
Drive browser forms, navigation, keyboard, pointer, scroll, drag, and uploads through DSH
Ref-pinned Chromium actions across Playwright, CDP accessibility/DOM, frames, tabs, and optional OCR surfaces
Developers building DSH workflows that need browser interaction beyond screenshot-only control
Interact with a background macOS application while another app remains active
Targeted AX, SkyLight, and CoreGraphics actions with post-action observation pinned to the previous target
Mac automation users who need window-specific control without moving the physical pointer
02How to install into DeepSeek Harness
Prerequisites
- macOS 14 or later
- DSH and Google Chrome must already be installed
- Authorize Accessibility and Screen Recording
Installation steps
- 01
Install with Homebrew: `brew tap zrui-c/tap`, `brew trust zrui-c/tap`, and `brew install --cask dsh-computer-use`
$ brew tap zrui-c/tap
- 02
Or download the latest `DSH-Computer-Use-*-universal.dmg` from Releases, drag DSH Computer Use into Applications, and open it
- 03
Select Install under DSH Plugin, then restart the running DSH Host

03DSH integration and capability boundaries
Native DSH bundle that registers computer_observe and computer_action in DSH's global tool layer
Semantic browser observation and actions
Chromium pages, tabs, frames, DOM/accessibility state, and optional OCR queries→Interactive, full, or changes snapshots; navigation, pointer, keyboard, forms, scroll, drag, and upload actions
File uploads are fenced to the DSH session workspaceBackground macOS window control
macOS accessibility trees, semantic gaps, target processes, and windows→AX actions and targeted SkyLight/CoreGraphics input, with global HID only without a target
Targeted actions do not move the physical pointerStale-target and semantic-state safety
A current observation and one browser or desktop action→Exactly one action followed by post-action semantic state; stale refs fail closed
Ref and coordinate actions require the latest snapshot_id
04Who is it for? When not to use it?
Good for
- DSH users on macOS who need targeted browser automation or background desktop control
- Developers building DSH workflows that need browser interaction beyond screenshot-only control
- Mac automation users who need window-specific control without moving the physical pointer
Not for
- The packaged application requires macOS 14 or later and the README requires DSH and Google Chrome to already be installed.
- Using the app requires Accessibility and Screen Recording authorization in macOS.
- The optional background input path dynamically loads private SkyLight symbols; Apple does not support those private APIs and they may change between macOS releases.
- UI and OCR strings are treated as untrusted data, and file uploads are limited to the DSH session workspace.

06Frequently asked questions
How does DSH Computer Use connect to DeepSeek Harness?
The package declares a DSH bundle, and cordis.patch.yml installs the Host runtime while registering computer_observe and computer_action in DSH's global tool layer. Install it from the setup center, then restart the running DSH Host.
Does it move my mouse when controlling another macOS window?
The README says targeted pointer and keyboard events route to the target process or window, while targeted actions do not move the physical pointer. Global HID is used only without a target.
What does computer_observe return?
It returns interactive, full, or changes snapshots for browser and desktop surfaces, with optional query filtering and auto, always, or never OCR. Actions return fresh bounded text observations.
What permissions and software are required?
Use macOS 14 or later, with DSH and Google Chrome installed. Authorize Accessibility and Screen Recording, install the DSH Plugin from the setup center, and restart the DSH Host.
Is the background input path suitable for the Mac App Store?
No. The README says the optional background input path dynamically loads private SkyLight symbols and is intended for Developer ID distribution, not the Mac App Store.
