## Support both macOS architectures
In order to support both macOS architectures, we must modify the `loadIndirect()` method a little further:
```python
import platform
def loadIndirect():
if sys.platform == "linux":
# libname = "lib{}.so"
# libname = os.path.join(os.path.dirname(__file__), "lib{}.so")
libname = os.path.join(os.path.dirname(__file__), "linux-x86_64/lib{}.so")
elif sys.platform == "darwin":
# libname = "lib{}.dylib"
# libname = os.path.join(os.path.dirname(__file__), "lib{}.dylib")
if platform.machine() == "arm64":
libname = os.path.join(os.path.dirname(__file__), "darwin-arm64/lib{}.dylib")
elif platform.machine() == "x86_64":
libname = os.path.join(os.path.dirname(__file__), "darwin-x86_64/lib{}.dylib")
elif sys.platform.startswith("win"):
# As of python3.8, ctypes does not seem to search $PATH when loading DLLs.
# We could use `os.add_dll_directory` to configure the search path, but
# it doesn't feel right to mess with application-wide settings. Let's
# assume that the `.dll` is next to the `.py` file and load by full path.
libname = os.path.join(
os.path.dirname(__file__),
"{}.dll",
)
return getattr(ctypes.cdll, libname.format("bdkffi"))
```
