General purpose computing on GPU

I've recently moved to Mac. And even though I like OS X itself, I find it way too outdated in terms of working with GPU based calculations.

I realize that notebook is not the best thing for heavy computing, but even regarding study projects it's quite outdated.

I realized that due to AMD my CUDA adventures would have to stop, but I really counted on OpenCL which appears to be v1.2, while there's 3.0 is out.

And it does not seem to be replaced with something. E.g. Keras uses PlaidML, which is based on that utterly outdated CL version.

I obviously see bootcamp as one of the solutions, but is there anything which would allow me to use OS X while still having an ability to run experiments with parallel computing?

Oh, I kind of found Metal, but question still persists since I'd rather work with something more portable.

UPD: And yes, plaidml appears to have metal backend.
