Finder thumbnails and "Open with" registration fail in the field for
three compounding reasons: the app claims com.autodesk.dwg/.dxf but
never declares them (UTImportedTypeDeclarations was missing, so on
systems with no other declarer Launch Services can't bind the
extensions at all); the QuickLook appex only serves com.autodesk.dwg
while machines with AutoCAD installed resolve .dwg to its exported
com.autodesk.autocad.dwg (BricsCAD etc. likewise win with their own
UTIs); and the ad-hoc --deep signature carries no entitlements, but a
QuickLook thumbnail extension must be sandboxed
(com.apple.security.app-sandbox) before macOS will run it.
Import-declare both UTIs, claim and serve the AutoCAD variants too,
add the appex sandbox entitlements, and add
packaging/build_macos_signed.sh — a local mirror of the CI build-macos
job that signs with a Developer ID (hardened runtime, per-component
entitlements), notarizes and staples. DEVELOPER_ID=- reproduces the
CI ad-hoc build.
