Will macOS x86 still be supported for the next few years?

Pytorch ditched official support for macOS x86 builds, see pytorch/pytorch#114602 and Tensorflow did the same as well, see https://github.com/tensorflow/tensorflow/releases/tag/v2.16.1
Makes me wonder if Jax soon will do the same. I have to choose the deep learning stack for an upcoming project and support for Intel Macs is one of the requirements. Hence the question :)

Hi!

Ultimately we're in the same boat as TF and PyTorch: Mac x86 hardware is becoming increasingly scarce, which makes life harder for engineers to fix the code if it breaks.

We'll make a best effort to keep the Mac x86 builds around and working as long as we can, but they are liable to be removed if:
a) the infrastructure that runs our CI drops support for Mac x86. With no CI, we can't test what we release. We wouldn't intentionally break builds, but with no testing things will break eventually.
b) we hit a problem that we can't easily solve. So far Mac x86 has been reasonably painless to keep working, but if we hit a problem that required significant work we might decide that the time had come to retire that build.

There's no timeline for either. It seems likely that (a) will happen at some point in the future, although I don't know when.

Make sense? We'll do our best, but no guarantees.

Thanks for the detailed explanation. Makes sense to me. Cheers!
