Three coupled fixes that close the macOS bring-up loop:
## 1. ifcwrap: fix INSTALL_RPATH on Apple
The ifcopenshell_wrapper Python module had `INSTALL_RPATH "$ORIGIN"` set
for "NOT WIN32 AND NOT WASM_BUILD" — but `$ORIGIN` is a Linux ld.so
placeholder, not a macOS dyld one. macOS dyld doesn't expand it; it
bakes the literal string `$ORIGIN` into LC_RPATH, which resolves to
nothing at runtime. The wrapper's hard-link `@rpath/ifcopenshell
.document.rdb.dylib` then fails to load even though INSTALL(TARGETS …
LIBRARY DESTINATION "${python_package_dir}/ifcopenshell") above had
already dropped the plug-in dylib right next to the wrapper.
Split the rpath assignment: `@loader_path` on Apple (the dyld
equivalent of `$ORIGIN`), `$ORIGIN` elsewhere.
This is what b0ef47819 (the build_osx IFCOS_BUILD_PYTHON_WRAPPER=off
gate) was working around. The gate is removed below.
## 2. ifcviewer-minimal: stage IfcOpenShell + wgpu_native into the .app
IfcViewerMinimal.app was building on macOS via the cmake
`BUILD_BONSAIVIEWER → BUILD_BONSAIVIEWER_WGPU` promotion, but had no
bundle staging — Contents/Frameworks/ only contained the Qt
frameworks macdeployqt deposited, so the .app would refuse to start
("Library not loaded: @rpath/libwgpu_native.dylib").
Mirror what src/bonsaiviewer/CMakeLists.txt does for BonsaiViewer.app:
* Set INSTALL_RPATH to `@executable_path/../Frameworks` so the exe
knows where to look for @rpath/* deps.
* install(FILES) libwgpu_native.dylib into the bundle's Frameworks/
(globbed from WGPU_NATIVE_LIB_DIR rather than hard-coded so it
covers any future versioned name).
* install(CODE) staging block that copies every `*.dylib` from
<prefix>/lib/ into the bundle's Frameworks/, excluding the
geometry-writer plug-ins (same EXCLUDE regex as BonsaiViewer.app —
viewer doesn't need OBJ/glTF/DAE/STP/IGS/SVG/TTL export converters).
Same long-form rationale + caveats apply (macdeployqt doesn't follow
non-Qt @rpath deps, lib-prefixed core libs vs ifcopenshell.* plug-in
naming split, Linux's equivalent lives in build_rocky.yml workflow
bash via patchelf + stage_runtime_payload). See src/bonsaiviewer/
CMakeLists.txt for the full version.
## 3. build_osx.yml: drop IFCOS_BUILD_PYTHON_WRAPPER=off
With (1) fixed, the Python wrapper smoke test should pass again. The
gate goes away; the comment block in build_osx.yml is replaced with a
short note pointing at the ifcwrap rpath fix as the underlying change
that re-enables this.
Together, (1)+(2)+(3) close the standalone IfcViewerMinimal-on-macOS
gap (task #43) and re-enable IfcOpenShell-Python on the macOS arm64 CI.

IfcOpenShell
IfcOpenShell is an open source (LGPL) software library for working with Industry Foundation Classes (IFC). Complete parsing support is provided for IFC2x3 TC1, IFC4 Add2 TC1, IFC4x1, IFC4x2, and IFC4x3 Add2. Extensive geometric support is implemented for the IFC releases IFC2x3 TC1 and IFC4 Add2 TC1. Extending with support for arbitrary IFC schemas is possible at compile-time when using C++ and at run-time when using Python.
In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an application to convert IFC models to other formats), Bonsai (an add-on to Blender providing a graphical IFC authoring platform), and many other libraries, CLI apps, and more. Support is also provided for auxiliary standards such as BCF and IDS.
