Download pre-built binaries from the releases page:

Development Builds

Pre-built binaries are available from GitHub Actions:

• macOS: Signed and notarized DMG
  • macos-dmg-x64 (Intel Macs)
  • macos-dmg-arm64 (Apple Silicon)
• Linux: AppImage (portable, works on most distros)

To download:

1. Go to the Build workflow
2. Click on the latest successful run
3. Scroll down to "Artifacts" section
4. Download the appropriate artifact for your platform

Installation

macOS:

1. Download the DMG file for your Mac:
   • Intel Mac: macos-dmg-x64
   • Apple Silicon: macos-dmg-arm64
2. Open the DMG file
3. Drag Cmux to Applications folder
4. Open the app normally

The app is code-signed and notarized by Apple, so it will open without security warnings.

Linux:

1. Download the AppImage file
2. Make it executable: chmod +x Cmux-*.AppImage
3. Run it: ./Cmux-*.AppImage

Testing Pre-Release Builds

⚠️ Note: Only builds from the main branch are signed and notarized. If you're testing a build from a pull request or other branch, you'll need to bypass macOS Gatekeeper:

1. After installing, open Terminal
2. Run: xattr -cr /Applications/Cmux.app
3. Run: codesign --force --deep --sign - /Applications/Cmux.app
4. Now you can open the app normally
