The AUTARQ macOS build is orchestrated from DesktopEditors/build, next to the existing Linux build entrypoint. On Apple Silicon it produces one suite app:

• AUTARQ Office.app

• Apple Silicon Mac
• Xcode installed and selected with xcode-select
• Git and Python 3
• Qt 5, for example Homebrew qt@5
• At least 120 GiB free disk space for native dependencies and build output

Clone the AUTARQ GitHub fork with submodules:

mkdir -p ~/Dev/autarq-office-desktop
cd ~/Dev/autarq-office-desktop

git clone \
  --branch autarq-office \
  https://github.com/Autarq/DesktopEditors.git

cd DesktopEditors
git submodule sync --recursive
git submodule update --init --recursive

Run the macOS preflight and build:

cd build
./macos/build.sh --check
MIN_FREE_GIB=120 ./macos/build.sh arm64

The apps are written to:

DesktopEditors/build/deploy/macos/arm64/AUTARQ Office.app

The macOS exporter also installs the pinned ONLYOFFICE draw.io plugin into the suite bundle.

It also preconfigures the bundled AI agent with the AUTARQ OpenAI-compatible endpoint. For private local builds, pass AUTARQ_AI_API_KEY to embed a key into the generated .app; leave it unset for commits and shared source builds.

For local desktop-apps development, keep a sibling checkout and point the build at it:

DESKTOP_APPS_DIR=~/Dev/autarq-office-desktop/desktop-apps \
  MIN_FREE_GIB=120 ./macos/build.sh arm64

Without a Developer ID identity the apps are ad-hoc signed and suitable for local testing. Release signing and notarization require the usual Developer ID and notarization credentials.
