📝 WalkthroughWalkthroughmacOS packaging now produces arm64 and x64 DMG and ZIP artifacts. Native CUA resources and the speech helper support both architectures. A feed regeneration script verifies release metadata, and the README adds an Intel download entry. ChangesUniversal macOS builds
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change adds Intel macOS packaging and release-feed handling, but the current branch can leave update metadata invalid if feed validation or writing is interrupted, and the documented download links can direct users to missing or incorrect release assets. Merge should wait until the release tooling and both macOS download links are corrected. Sequence Diagram(s)sequenceDiagram

Closes #257. The published mac app was arm64-only; an Intel Mac cannot run it and Rosetta does not translate in that direction. - electron-builder.yml: dmg + zip for [arm64, x64]. The dmg section's own artifactName override was arch-less, so the x64 dmg silently OVERWROTE the arm64 one on the first dual-arch build and the feed listed one filename twice with two different hashes — it now carries ${arch}. extraResources resolve through dist-native/${arch} so each bundle ships its own natives. - pnpm.supportedArchitectures.cpu = [arm64, x64]: pnpm installs both darwin CUA native packages (x64 exists at the exact pinned 0.20.0); lockfile is byte-identical. - prepare-cua.mjs: stages per-arch dirs, asserts the driver binary is genuinely universal via lipo (a future non-universal pin fails at package time, not on a user's Intel Mac), and falls back to the official universal download when the locally installed CuaDriver.app is single-arch. The pure-JS SDK bundle is built once and shipped in both dirs. - build-speech-helper.mjs: two swiftc passes targeting {arm64,x86_64}-apple-macos12 (the app's LSMinimumSystemVersion), lipo'd and asserted universal — bare swiftc built host-arch only, which inside an Intel app is a dictation helper that cannot launch. - scripts/regenerate-mac-feed.mjs (new): refreshes latest-mac.yml hashes after notarization stapling rewrites artifact bytes, preserving electron-builder's file order (electron-updater filters that list by arch: arm64-marked files on Apple silicon, unmarked on Intel) and verifying every entry against the bytes on disk before finishing. - smoke-cua.mjs follows the per-arch staging layout; README gains the Intel download row (stable name: OpenMausBot-intel.dmg). Verified: four distinct artifacts; app binaries x86_64/arm64 respectively; universal cua-driver and speech helper inside the x64 bundle; the x64 app launched under Rosetta on this arm64 Mac with a sandboxed data dir — server forked, /api/health static:true, all 8 spawned proxy paths resolving inside Resources/server; full suite green (1187 passed).

Update both macOS download links.
OpenMausBot-intel.dmg returns 404. The latest release publishes the unmarked x64 DMG and an arm64 ZIP only. OpenMausBot.dmg therefore does not provide an Apple silicon DMG. Publish stable aliases for both architectures or link to the correct release assets.

Write the feed only after validation succeeds.
writeFileSync(feedPath, updated) runs before the verification loop. If verification fails or the process stops during the write, latest-mac.yml can remain partially updated or invalid. Validate the generated content first, then write through a temporary file and atomically rename it into place.

Closes #257 — the published mac app was Apple silicon only, and Rosetta does not translate in that direction.
What this does
Every release now produces four mac artifacts:
OpenMausBot-<v>-{arm64,x64}.{dmg,zip}. electron-updater already routes by filename on macOS (arm64-marked files on Apple silicon, unmarked ones on Intel), so existing users are unaffected and Intel users get real auto-updates.Local computer use works fully on Intel — no Silicon-only carve-out was needed: the pinned CUA driver release is a universal binary, and
@trycua/cua-driver-darwin-x64exists at our exact pinned 0.20.0.The changes
electron-builder.yml— dmg+zip for[arm64, x64];extraResourcesresolve throughdist-native/${arch}so each bundle carries its own natives. One trap found empirically: thedmg:section's ownartifactNamewas arch-less and overrides everything, so on the first dual-arch build the x64 dmg silently overwrote the arm64 one and the feed listed one filename with two hashes. It now carries${arch}.package.json—pnpm.supportedArchitectures.cpu: [arm64, x64]so pnpm installs both darwin natives. Lockfile is byte-identical.scripts/prepare-cua.mjs— per-arch staging; asserts the driver is genuinely universal withlipo(a future non-universal pin fails at package time, not on a user's Intel Mac); falls back to the official universal download if the locally installed CuaDriver.app is single-arch.electron/build-speech-helper.mjs— twoswiftcpasses targeting{arm64,x86_64}-apple-macos12(matches the app'sLSMinimumSystemVersion),lipo'd and asserted universal. Bareswiftcbuilt host-arch only — inside an Intel app, a dictation helper that cannot launch.scripts/regenerate-mac-feed.mjs(new) — release tooling: refresheslatest-mac.ymlhashes after notarization stapling rewrites the bytes, preserving electron-builder's file order (which the updater's arch filtering depends on) and refusing to finish unless every entry matches the bytes on disk.OpenMausBot.dmgis unchanged, Intel getsOpenMausBot-intel.dmgat publish time.Verification
x86_64/arm64respectively;cua-driverand the speech helper inside the x64 bundle are universal (lipo -archs)OMB_DATA_DIR/--user-data-dir: server forked,/api/healthreturnedstatic: true, and all 8 spawned proxy paths resolve insideResources/serverRelease-flow note
The next release cut from main after this merges will produce 4 mac artifacts to notarize/staple instead of 2 (the versioned arm64 dmg name changes from
OpenMausBot-<v>.dmgtoOpenMausBot-<v>-arm64.dmg), and should uploadOpenMausBot-intel.dmgas a stable-named copy next to the existingOpenMausBot.dmg. Auto-update for existing arm64 users is unaffected — updates ship via the zip, whose name is unchanged.🤖 Generated with Claude Code
