When checked, both download responses named version 0.2.2-rc.1; the file date comes from the HTTP response. We did not install or verify the installers' signatures, and the aliases may change.
The Windows nightly feed and macOS ARM64 nightly feed both listed 0.2.2-rc.1 with a 100% rollout. This is a feed snapshot, not confirmation of the stable channel or an individual device's update state.
A Windows user reported missing workspace records, sessions and plugin state after updating from 0.2.1-rc.5 to 0.2.2-rc.1, while project files remained. The cause and an official fix have not been confirmed. Before updating, quit DSH, identify the actual DSH_HOME path and back it up separately. The backup can contain credentials; keep it secure.

First run
- 01
Install and open the app
Open the EXE on Windows, or the DMG on Apple Silicon Mac and move the app to Applications. Desktop does not require a separate Node.js installation.
- 02
Configure a model
Add provider credentials in the local app and choose an available model. The installer does not include API credits.
Open model setup → - 03
Verify a test workspace first
Select a disposable folder without secrets. Ask DSH to list files without changing them and verify the actual path before using a real project.
Open the first-task guide →
Context and text controls
Compact context manually
Web and Desktop can both run /compact in the conversation to ask DSH to compact the current context manually. It does not change the session mode.
Resize Desktop text
On Desktop, use Cmd/Ctrl + + to increase and Cmd/Ctrl + - to decrease the body, code and terminal font size together.
Minimal mode can read images and automatically compact long conversations. That is mode-specific automatic behavior; /compact remains a manual Web/Desktop action.
Common download and first-run issues (FAQ)
Check your Mac's chip
Use About This Mac to distinguish Apple M-series from Intel. Do not use this ARM installer on an Intel Mac.
Mac reports unverified developer
If macOS blocks opening, go to System Settings → Privacy & Security and click 'Open Anyway', or run xattr -cr '/Applications/DeepSeek Harness.app' in Terminal.
Windows SmartScreen prompt
If Windows Defender SmartScreen shows 'Windows protected your PC', click 'More info' and select 'Run anyway'.
The composer is disabled
Check saved credentials, model selection and the test workspace, then follow the actual error.
