macOS Dev Setup
Setup guide for developers working on the OpenClaw macOS app
macOS Developer Setup
This guide covers the necessary steps to build and run the OpenClaw macOS application from source.
Prerequisites
Before building the app, ensure you have the following installed:
- Xcode 26.2+: Required for Swift development.
- Node.js 22+ & pnpm: Required for the gateway, CLI, and packaging scripts.
1. Install Dependencies
Install the project-wide dependencies:
pnpm install
2. Build and Package the App
To build the macOS app and package it into dist/OpenClaw.app, run:
./scripts/package-mac-app.sh
If you don't have an Apple Developer ID certificate, the script will automatically use ad-hoc signing (-).
For dev run modes, signing flags, and Team ID troubleshooting, see the macOS app README: https://github.com/openclaw/openclaw/blob/main/apps/macos/README.md
Note: Ad-hoc signed apps may trigger security prompts. If the app crashes immediately with "Abort trap 6", see the Troubleshooting section.
3. Install the CLI
The macOS app expects a global openclaw CLI install to manage background tasks.
To install it (recommended):
- Open the OpenClaw app.
- Go to the General settings tab.
- Click "Install CLI".
Alternatively, install it manually:
npm install -g openclaw@<version>
Troubleshooting
Build Fails: Toolchain or SDK Mismatch
The macOS app build expects the latest macOS SDK and Swift 6.2 toolchain.
System dependencies (required):
- Latest macOS version available in Software Update (required by Xcode 26.2 SDKs)
- Xcode 26.2 (Swift 6.2 toolchain)
Checks:
xcodebuild -version
xcrun swift --version
If versions don’t match, update macOS/Xcode and re-run the build.
App Crashes on Permission Grant
If the app crashes when you try to allow Speech Recognition or Microphone access, it may be due to a corrupted TCC cache or signature mismatch.
Fix:
- Reset the TCC permissions:
tccutil reset All bot.molt.mac.debug - If that fails, change the
BUNDLE_IDtemporarily inscripts/package-mac-app.shto force a "clean slate" from macOS.
Gateway "Starting..." indefinitely
If the gateway status stays on "Starting...", check if a zombie process is holding the port:
openclaw gateway status
openclaw gateway stop
# If you’re not using a LaunchAgent (dev mode / manual runs), find the listener:
lsof -nP -iTCP:18789 -sTCP:LISTEN
If a manual run is holding the port, stop that process (Ctrl+C). As a last resort, kill the PID you found above.
