Summary

The macOS app shipped in v2026.2.26 is arm64-only. It crashes immediately on Intel Macs with "You can’t open the application ‘OpenClaw’ because this application is not supported on this Mac." v2026.2.25 was a universal binary and worked correctly.

Steps to reproduce

1. Download OpenClaw-2026.2.26.zip from https://github.com/openclaw/openclaw/releases/download/v2026.2.26/OpenClaw-2026.2.26.zip
2. Unzip and attempt to open OpenClaw.app on an Intel Mac
3. macOS shows: "You can’t open the application ‘OpenClaw’ because this application is not supported on this Mac."

Verification:

$ lipo -info OpenClaw.app/Contents/MacOS/OpenClaw
Non-fat file: OpenClaw.app/Contents/MacOS/OpenClaw is architecture: arm64

$ file OpenClaw.app/Contents/MacOS/OpenClaw
OpenClaw.app/Contents/MacOS/OpenClaw: Mach-O 64-bit executable arm64

Expected behavior

OpenClaw.app opens normally on Intel Macs, as it did in v2026.2.25 which was a proper universal binary (x86_64 + arm64).

Actual behavior

App fails to launch on Intel Mac. macOS shows "not supported on this Mac" error. Finder Get Info shows Kind: Application (Apple silicon). Screenshot attached showing both the Get Info dialog and the macOS error.

lipo output confirms arm64-only:

Non-fat file: OpenClaw.app/Contents/MacOS/OpenClaw is architecture: arm64


Screenshot below shows Finder Get Info (Kind: Application (Apple silicon)) and the macOS launch error side-by-side. Screenshot attached.

Impact and severity

Affected: All Intel Mac users
Severity: Critical — complete blocker, app will not open at all
Frequency: 100% repro on any Intel Mac
Consequence: Intel Mac users cannot run the OpenClaw app; must stay on v2026.2.25 or run from source

Additional information

• v2026.2.25 was a universal binary (x86_64 + arm64) and worked correctly on Intel Macs — this is a clean regression in the build pipeline
• PR fix(mac): default to universal binary for distribution builds #1396 (merged Jan 22, 2026) previously fixed the same issue; the fix appears to have been dropped
• Workaround: stay on v2026.2.25 or run from source (npm install -g openclaw works fine on Intel)
• The npm package is unaffected — only the macOS .app/.dmg/.zip release assets are broken
