Hey!
We still have macos x86 CI as the moment since it was not removed yet so it should still work (at least for some versions of macos).
Compiling on your local x86 mac will take quite a bit of time I’m afraid so might not be the best experience indeed.
One alternative is to use github.dev that will use the provided devcontainer at pytorch/.devcontainer/README.md at main · pytorch/pytorch · GitHub to have an easier setup
