Mac-specific features in DeepSeek Harness desktop
- Menu-bar
dshcommand: install and manage the plugin command without Node or pnpm. - Login-shell environment: launching from the Dock now picks up your PATH, proxies and tool settings.
- Reliable window dragging from the top bar, with buttons and dialogs still usable.
- Background tasks that continue when you close the window — quitting warns you first.
Intel Macs: the download page lists Apple Silicon; the v0.2 release notes mention a fix for the Intel build’s bundled runtime, so check the page for an Intel option.

Getting the most from DeepSeek Harness on a Mac
Use Creator mode to customise plugins, connect free models through OpenCode or OpenRouter, and turn on the automation task plugin for recurring jobs — mine builds a weekly AI news deck. Voice input works well on a Mac once the microphone permission is granted.
Before you start, dated 5 October 2026: DeepSeek Harness is open source (MIT) but built by a Chinese company, so I don’t put private client data or anything sensitive into it. The desktop app is labelled a preview, and features move weekly — check the release notes for the current state.
The bottom line on DeepSeek Harness desktop macOS
DeepSeek Harness desktop macOS is a free Apple Silicon app that brings your history with it, manages plugins from the menu bar, respects your shell setup and keeps tasks running in the background. Download it from deepseek.com/harness, grant mic access and pick Creator mode.
What I’d set up first
- A free model through OpenCode or OpenRouter, so testing costs nothing.
- Creator mode, so you can customise plugins as you go.
- One scheduled task — a weekly report or deck — to see automation working.
- Voice input, if you like talking through tasks.
DeepSeek Harness desktop macOS workflow and models
On my Mac, a typical session looks like this:
- Start a new session and pick the project folder you want to work in.
- Choose a mode — Creator if you want to customise, Standard for normal coding.
- Confirm your model in the session header.
- Click the plus button to open extra chats and run agents in parallel.
- Rename projects and sessions so your history stays organised.
And these are the model providers I connect:
| Provider | Why use it |
|---|---|
| OpenCode | Free custom models with just an API key — my go-to for zero-cost coding |
| OpenRouter | A wide catalogue, including free models, on one key |
| DeepSeek | DeepSeek’s own models plugged straight in — I ran DeepSeek V4.13 in my test |
v0.2 also made the harness far better with everyday files: it can edit documents, spreadsheets and PDFs, organise information, analyse data, make charts and build slide presentations, with previews of Office files, PDFs, images and Markdown right in the sidebar. That turns it from a coding tool into a general AI worker — I’ve had it build landing pages and decks from the same session.
