Implements quest/m0/packaging/macos.md, and deletes it.

Problem

Releases ship only the Flatpak. On macOS the studio isn't an app bundle, so the terminal that launched it gets asked for camera, microphone, and screen recording access. Nothing builds, signs, or notarizes a Mac app.

Approach

• packaging/macos/:
  • bundle.sh builds moq-studio with release for the host's architecture (MACOSX_DEPLOYMENT_TARGET=13.0) and lays out kixel.live Studio.app.
  • Info.plist sets bundle ID live.kixel.studio, the camera, microphone, and screen-capture usage strings, and LSMinimumSystemVersion 13.0, the first release with ScreenCaptureKit's system audio.
  • entitlements.plist holds the hardened runtime's camera and audio-input exceptions.
  • sign.sh signs with the hardened runtime and those entitlements. The identity is a Developer ID, or - for an ad hoc signature. A comment marks where nested code (CEF helpers, the camera extension) gets signed first, innermost first.
  • dmg.sh packs the app into a disk image with the usual drag-to-Applications window: the app beside an Applications link, 128 pt icons, no toolbar, and the app's icon as the volume icon. Given an identity, it signs the image too. The window's layout comes from dmgbuild (dmg.py), which writes the .DS_Store itself instead of scripting Finder, since Finder automation times out on hosted runners. It is pinned by hash in dmg-requirements.txt and installed in a throwaway venv, since the release job runs it.
  • notarize.sh notarizes a signed app (zipped for upload) or disk image with notarytool --key. It prints the notary log, fails unless the status is Accepted, then staples and validates the ticket.
  • smoke.sh is the macOS counterpart of the Flatpak check. Given a .dmg, it mounts it, checks for the Applications link, and runs the app inside. It launches the bundle through Launch Services, as Finder does, with a fresh HOME. It requires cameras=Ok(..) and audio=Ok(..) in the log, then finds the window through CGWindowListCopyWindowInfo, which needs no permission. Finally it quits the app by Apple event and fails on a crash report or a panic.
• build.rs writes the .icns from packaging/live.kixel.studio.svg for a macOS target: 16 to 512 points at 1x and 2x, PNG entries. No .icns is checked in.
• .github/workflows/macos.yml:
  • Bundle: one job per architecture on its native runner (macos-15, macos-15-intel). It builds, signs ad hoc, packs the unsigned disk image, runs the smoke test from it, and uploads unsigned-macos-<arch> (the .dmg). Pull requests that touch the packaging run it, and nightly runs it.
  • Sign: runs only with sign: true, which only release.yml passes, and uses the release environment. It copies the app out of the unsigned image and imports the .p12 into a throwaway keychain, along with Apple's Developer ID G2 intermediate (pinned SHA-256). It signs the app, then notarizes and staples it. Next it packs and signs the disk image, then notarizes and staples that too. It deletes the keychain, which happens always() before anything built runs. Then spctl must report source=Notarized Developer ID for both the image (--type open) and the app (--type execute). Last, it runs the smoke test from the signed image and uploads macos-<arch>.
• release.yml calls it, and publish downloads only {flatpak,macos}-*.
• With no scene file named (a desktop launch passes no arguments), the studio opens scenes.toml in its data directory (eframe::storage_dir("moq-studio"), beside app.ron) and creates the directory. Recordings then go to the videos folder (dirs::video_dir), since nobody looks for them in Application Support. Before this, a launch with no scene file was an error.
• Cmd-Q ends the studio. winit's macOS Quit item (also the Dock's Quit and logging out) calls terminate:. After winit's LoopExiting, AppKit calls exit(), so run_app never returns. main's post-loop shutdown never ran: no save of the last second of edits, no finished recording, no clean relay close. The shutdown now runs in ApplicationHandler::exiting, which every exit path reaches.

Impact

• New release assets: moq-studio-macos-arm64.dmg and moq-studio-macos-x86_64.dmg, each a signed, notarized, stapled disk image holding a signed, notarized, stapled kixel.live Studio.app for macOS 13+.
• moq-studio with no scene file opens <data dir>/moq-studio/scenes.toml, with recordings in the videos folder, instead of erroring. Naming a scene file works as before.
• Quitting from the macOS app menu or Dock now saves, finishes a recording, and closes relay sessions, as closing the window did.
• README: macOS install section, both defaults, and the permissions note now covers builds from source only.
• No public API or wire change.

Validation

• DMG: macOS run on 9525c52 and on 9cbf55a: both architectures pass. dmg.sh builds the image with dmgbuild on Python 3.13, and smoke.sh mounts the image, checks the Applications link, and launches the app from it (listed devices cameras=Ok(0) ... audio=Ok(..), window found, clean quit). Bundle took 40 min on arm64 and 44 min on x86_64.
• Bundle (arm64) on hosted macos-15: build 39 min, then codesign --verify --strict passes on the ad hoc signature. The smoke test logs listed devices cameras=Ok(0) ... audio=Ok(..), finds the window, and the app quits by Apple event without a crash.
• Bundle (x86_64) on hosted macos-15-intel: the build takes 61 min under fat LTO, inside the 120 min timeout. The smoke test passes the same way, and the window is found, so Metal draws on the Intel VM. These macOS jobs run only for PRs that touch the packaging, nightly, and releases, so the merge gate is unchanged.
• On a real Mac (kixtop, macOS 26.6.2, arm64), I built with bundle.sh (10 min clean) and signed ad hoc with sign.sh. codesign -d --entitlements - shows flags=0x10002(adhoc,runtime) and both entitlements. smoke.sh passed: cameras=Ok(1), audio=Ok(4), and VideoToolbox timed at every canvas. iconutil -c iconset reads the .icns back into all ten sizes, the largest 1024 px.
• I checked the Cmd-Q fix on kixtop against a build with a temporary log line at the end of shutdown. I opened the studio on shots/show.toml and quit it by Apple event, the same terminate: path the Quit menu uses. The log showed the shutdown line, and the process exited.
• On kixtop, dmg.sh (Homebrew Python 3.13) packed a stand-in bundle. The mounted image held the app, Applications -> /Applications, .DS_Store, and .VolumeIcon.icns.
• just ci passes locally. New tests: a_missing_folder_is_created (a recording creates its missing folder, such as a videos folder not yet made) and an_uncreatable_directory_fails_to_start.
• Flatpak (pre-existing failure): the Flatpak's Bundle jobs fail on this PR (run) exactly as on main (gh workflow run flatpak.yml --ref main, on 354ee7d). Both fail with cameras=Err("camera portal: ZBus Error: D-Bus handshake failed: Unexpected EOF during handshake"). The last green Nightly ran on a73fb69, before feat!: catch the studio up to moq's main #163 moved moq-video's camera portal to ashpd 0.14 / zbus 6.3. The follow-up below owns it. New unit test: defaults_to_the_collection_in_the_data_directory.
• Signing path: a PR cannot deploy the release environment, so the real Sign job is unexercised. The PR's Bundle job exercises everything except the identity and notarization: the same sign.sh, hardened runtime, entitlements, and Launch Services launch. actionlint (with shellcheck) checks the Sign job's shell. The first release run is its first end-to-end check, which the follow-up below confirms, and it fails loudly at each step: no identity found, a status other than Accepted (the notary log prints either way), stapler validation, or the spctl source.

Decisions

Decided 2026-11-15 (maintainer, comment):

• The hand check: ✅ move the camera-picture check, and confirming the first release's real Developer ID signing and notarization, into a maintainer follow-up quest to try the macOS app, then take this PR through review and mark it ready (rejected: keep the PR a draft until the check is done).
• Release format: ✅ a DMG per architecture. The release signs, notarizes, and staples the .app, then signs, notarizes, and staples the .dmg holding it, laid out for dragging to Applications. release.yml publishes the DMGs (rejected: zip, this PR's first choice; both). The unsigned PR and nightly artifact is the DMG too, so the hand check installs the same way a release does. The launch check runs the app from the mounted DMG on both paths.
• The PR's other calls are kept: ✅ one app per architecture; the no-argument default applies on every platform; no embedded provisioning profile until the camera extension; the Cmd-Q shutdown fix ships here (rejected: flipping any of them).
  • One app per architecture, not universal. Each is built and launch-checked natively, and the bundle stays half the size, which matters once CEF's framework (hundreds of MB) joins it. GitHub keeps macos-15-intel until Aug 2027. After that, drop Intel or cross-compile it on arm64.
  • The no-argument default applies on every platform, not just in the bundle. The Windows installer's shortcut gets it for free, and moq-studio alone does something useful instead of erroring. The Flatpak's menu entry keeps its wrapper, now naming only the desktop's Videos folder, so it and flatpak run open the same default collection (found by reviewer; no release has shipped, so no collection moves).
  • APPLE_PROVISIONING_PROFILE is not embedded yet. Only the camera extension's system-extension.install entitlement needs it, and an unused profile is untestable weight. quest/m0/vcam/macos.md now says how to embed it.
  • The Cmd-Q fix rides along. Without it, the shipped app's normal quit loses the last edits and leaves recordings to crash repair.

Choices I made without asking, for review:

• dmgbuild for the window layout, not Finder AppleScript (create-dmg's approach), which needs Finder automation and intermittently times out on hosted runners. It is pinned by hash, runs no Finder, and the PR job builds with it too.
• The unsigned artifact is the DMG rather than a zip of the app, so the Sign job and a hand check start from what users download.

Caused by

• moq-dev/studio#4 - saved on quit after the window's event loop returns, which a macOS Quit never does (found by reviewer)

Follow-ups

• quest/m0/packaging/macos-try.md - the maintainer tries the macOS app: the camera's picture in program from the DMG's app, and the first release's real Developer ID signing and notarization of the app and the DMG. Kept by the maintainer's decision above; no open decisions.
• quest/m0/packaging/flatpak-cameras.md - main's Flatpak launch check fails at the camera portal's D-Bus handshake, likely since feat!: catch the studio up to moq's main #163's zbus 6. No open decisions; keep it (recommended), since the Flatpak release can't pass its check without it.

Maintainer decision on the macOS app (asked by the /quest-run coordinator, 2026-11-15):

1. The hand check: ✅ move the camera-picture check, and confirming the first release's real Developer ID signing and notarization, into a maintainer follow-up quest to try the macOS app. Then take this PR through review and mark it ready (rejected: keep the PR a draft until the check is done).
2. Release format: ✅ ship a DMG per architecture. Sign, notarize and staple the .app, then sign, notarize and staple the .dmg that holds it, with the usual drag-to-Applications window. release.yml publishes the DMGs (rejected: zip, which was the PR's choice; both).
3. The PR's other calls are kept: ✅ one app per architecture; the no-argument default applies on every platform; no embedded provisioning profile until the camera extension; the Cmd-Q shutdown fix ships here (rejected: flipping any of them).

(Written by Claude Opus 5.5 with high effort)

[kixelated]

Applied the maintainer's decision in 9525c52:

1. The camera-picture check and the first release's signing and notarization check now live in quest/m0/packaging/macos-try.md, listed under ## Follow-ups. The PR went through /quest-review and is ready for review.
2. Releases ship moq-studio-macos-<arch>.dmg. The Sign job signs, notarizes, and staples the app, then does the same for the image (packaging/macos/dmg.sh, notarize.sh). The PR and nightly artifact is the unsigned DMG, and the launch check runs the app from the mounted image on both paths.
3. The other calls are unchanged and recorded under ## Decisions.

Reviewed changes

I reviewed the whole PR at 9525c52: the macOS packaging scripts, the new reusable macos.yml workflow and how release.yml and nightly.yml call it, the .icns generation, and the main.rs changes to the default collection and quit path. quest context could not run because the review shell has no quest or nix.

• App bundle and signing scripts: bundle.sh, sign.sh, dmg.sh/dmg.py, and notarize.sh sign the app before the DMG that holds it. Ad hoc signing (-) runs the same hardened runtime and entitlements as the release, and notarization fails unless the status is Accepted.
• macos.yml: the Bundle job builds natively for each arch and smoke-tests from the DMG. The Sign job runs only when inputs.sign is set, under environment: release. Calling a reusable workflow without secrets: inherit still works here, because the APPLE_* secrets are environment secrets. The keychain is deleted always() before anything built runs. publish downloads {flatpak,macos}-*, which matches flatpak.yml's flatpak-<arch> artifacts and skips the unsigned-macos-* ones.
• smoke.sh: it launches the app through Launch Services with a fresh HOME and requires the device listing. It finds the window without needing a permission, quits by Apple event, and fails on a crash report or a panic.
• build.rs .icns: the ten PNG type codes and sizes (icp4 through ic10) are correct. Each entry's length counts its 8-byte header, and the total length is written back into the file header.
• Default collection: Files::new keeps the old behavior when a scene file is named. With none, the scene file defaults to scenes.toml in eframe::storage_dir("moq-studio") and recordings default to the videos folder. A missing parent directory is now created before setup writes the file. The Flatpak wrapper now shares this default.
• Quit path: shutdown moved from after run_app into ApplicationHandler::exiting, after eframe.exiting has saved app.ron. This is the root-cause fix for macOS terminate:, after which run_app never returns. Every other exit path still runs shutdown exactly once, and a save that fails on quit still becomes run()'s error through unsaved.

Walkthrough

The change adds macOS app bundles and disk images for ARM64 and x86_64, with smoke tests and optional Developer ID signing and notarization. Nightly and release workflows now include macOS artifacts. The studio resolves scene and recording paths together and performs shutdown when the event loop exits. The change also adds macOS icon generation, updates Flatpak scene selection, and revises release instructions and packaging plans.

Merge Risk: Minimal · previous review 9cbf5

This adds signed macOS app bundles and disk images, and updates the default scene and recording locations and quit-time shutdown. Previously raised concerns are resolved or withdrawn, so no concrete merge-blocking risk remains.

the legacy collection path to moq-studio. Preserve explicitly supplied arguments
and the existing recordings option.

Review comments at @packaging/macos/smoke.sh:
- Line 100: Update the crash-report scan using reports and marker so it checks
whether the report directory exists before invoking find, treating an absent
directory as no reports. For an existing directory, let scan failures remain
visible and propagate their status rather than suppressing stderr or masking
errors.

I reviewed the delta since the prior Pullfrog review at 9525c52.

• Recorder creates its folder: record.rs create now runs create_dir_all on the target directory, so a first recording into a missing videos folder works. A new test covers it, and the failure test now uses an uncreatable path.
• Smoke test crash scan: smoke.sh only runs find when the crash-report directory exists. Scan errors are no longer hidden.
• Quest wording: browser-source/macos.md now says CEF bundling and signing are work this quest adds to bundle.sh and sign.sh.

This doc comment about a taken name is now attached to a_missing_folder_is_created; it belongs on a_taken_name_is_numbered below. Move the new test above it, or give it its own doc line.

Suggested change

	/// A name already taken, such as by a recording started in the same
	/// A recording's folder, such as the videos folder, is created when missing.

Fixed in 90751a7: the new test sits above the doc comment, with one of its own.
