Summary:
Making sure we have the macOS build too.
To find the hash, see https://hud.pytorch.org/hud/pytorch/pytorch/nightly for the target date.
To test, check if the file like `torch-2.2.0.dev20231005-cp311-none-macosx_11_0_arm64.whl` exists at https://download.pytorch.org/whl/nightly/torch/ and run `./install_requirements.sh` on a Mac to see all the dependencies are successfully installed.
