Restore Intel compatibility for release artifacts#46
Merged
Conversation
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Release builds were being archived on Apple Silicon without an explicit generic macOS destination, which allowed arm64-only app bundles to be published. The workflow now forces a universal build for release artifacts and fails fast if the archived app does not contain both arm64 and x86_64 slices. Constraint: Release packaging must continue using the existing signing and notarization flow Rejected: Lower macOS deployment target | Intel launch failure was caused by architecture, not OS minimum version Confidence: high Scope-risk: narrow Reversibility: clean Directive: Keep the lipo verification in CI so Intel support cannot silently regress Tested: xcodebuild -showBuildSettings with generic/platform=macOS confirmed ARCHS=arm64 x86_64 and ONLY_ACTIVE_ARCH=NO; unsigned Release build produced a universal Capso binary verified with file and lipo Not-tested: End-to-end signed GitHub Actions release archive, notarization, and Intel hardware launch after release publishing

Summary
arm64+x86_64)Root cause
Issue #23 happened because the release workflow archived on Apple Silicon without an explicit generic macOS destination or universal arch override. That allowed GitHub release artifacts to be published as
arm64-only app bundles, which Finder rejects on Intel Macs with “this application is not supported on this Mac.”Impact
