Fix: macOS App "Not Supported on This Mac" on Intel — arm64-Only Regression
[Finder Get Info] Kind: Application (Apple silicon)
OpenClaw v2026.2.26 regressed from a universal binary (arm64 + x86_64) to an arm64-only build. Intel Macs running x86_64 cannot launch it and see "not supported on this Mac." The previous v2026.2.25 was a universal binary. Until a fixed release is published, the npm CLI is a full workaround.

Step 1: Confirm Your Mac Architecture
# Check architecture uname -m # x86_64 = Intel Mac (affected by this bug) # arm64 = Apple Silicon (not affected) # Also check the downloaded app binary file /Applications/OpenClaw.app/Contents/MacOS/OpenClaw # arm64 only: "Mach-O 64-bit executable arm64" # Universal: "Mach-O universal binary with 2 architectures"
Workaround: Use npm CLI Instead of the Desktop App
The npm package works identically on Intel Macs — it's JavaScript (Node.js), not a native binary. This is the recommended workaround until a universal app binary is released:
# Install Node.js first if needed: https://nodejs.org node --version # Should be >= 22.12.0 # Install OpenClaw CLI npm install -g openclaw # Start the gateway (equivalent to the desktop app) openclaw gateway start # Open the Control UI in your browser open http://localhost:18788
The npm CLI gives you full gateway functionality including all plugins, skills, and the web Control UI. The only thing you miss is the macOS menu bar icon from the desktop app.
Alternative: Downgrade to v2026.2.25 Desktop App
If you specifically need the desktop app, download v2026.2.25 (the last universal binary) from the OpenClaw GitHub releases page:
# Download v2026.2.25 (last universal binary) gh release download v2026.2.25 --repo openclaw/openclaw --pattern "OpenClaw-*-universal.dmg" --dir ~/Downloads
Check for a Fixed Universal Binary Release
# Check the latest release on GitHub gh release view --repo openclaw/openclaw # Or check the asset list for "universal" in the filename gh release list --repo openclaw/openclaw --limit 5
When a universal binary is released, the asset filename will include "universal" or list both "arm64" and "x86_64" architectures. Download and install it to replace the broken v2026.2.26 build.
