Install OpenChatCut desktop builds and fix common issues

This guide covers the OpenChatCut open-source edition. Installers come from the public repository's GitHub Releases and do not require a source build. Pro installation and licensing instructions will be published separately on the Pro page; these open-source installers are not Pro builds.

Download

Open the latest release:

https://github.com/0xsline/OpenChatCut/releases/latest

Typical assets:

  • macOS Apple Silicon — DMG
  • macOS Intel — DMG
  • Windows x64 — installer

Trust the filenames on the Release page. Linux packaging follows the repository and release notes.

macOS: unsigned / not notarized

Early builds may not be signed or notarized yet. On first open, macOS may block the app:

  1. Open System Settings → Privacy & Security and allow opening the app.
  2. Or Control-click → Open the app in Finder, then confirm.
  3. Managed devices may need an admin policy exception.

An unsigned-app warning does not establish that a build is safe. Check the official release source, notes and available verification information. If you cannot confirm the source, do not bypass the operating system's warning.

Windows

  1. Run the installer and finish the wizard.
  2. If SmartScreen reports an unknown publisher, choose More info → Run anyway only for official Releases you trust.
  3. If security software blocks first launch, allowlist the app.

First-launch checklist

  • Preview and timeline render correctly
  • Local audio/video import works
  • Configure model keys only when you need the built-in agent or external MCP
  • Projects stay local by default (see app/docs notes about ~/.openchatcut)

Prefer source?

For development, debugging, and contributions, running from source is more transparent. See Run OpenChatCut from source and the main README.

Upgrading

  1. Read the open-source changelog, check the target release's known issues and back up your projects
  2. Quit OpenChatCut
  3. Download the matching platform build and follow its release instructions

Project data is not deleted by a normal install; check release notes for major migrations.
