 ### Differences from the standard ``multibuild`` instructions
 
 - `BUILD_COMMIT` is automatically set to the most recent tagged version of `httpstan`. See `.github/workflows/wheels.yml`.
-- `MB_PYTHON_OSX_VER=10.9` is set in `.github/workflows/wheels.yml`.
-- To avoid building universal wheels on macos, `ARCHFLAGS` is set to `-arch x86_64` in `.github/workflows/wheels.yml`. Setting `ARCHFLAGS` on macos influences what Python uses as `CFLAGS`. The httpstan `Makefile` gets `CFLAGS` from Python and uses them when compiling `httpstan/stan_services.cpp`.
