Macos on ARM—coming soon

However, the ZombieLoad exploit will likely be the last straw for Apple with Intel.

And the FULL mitigation (turn off hyperthreading entirely) has up to 40% performance hit with ALL Intel processors back to 2011 with ALL OSes.  Only really paranoid top-secret installations and super-secure banking/business, etc., need to do this (probably).

"New" point (.) updated MacBook Pro 15 released today with "new" under-the-hood keyboard change. Slightly faster core i9 cpu, more RAM at 32 GB, etc., but nothing revolutionary and still with that awful touchbar. Bloody expensive too, of course. 
Odd to announce this about 10 days before WWDC—clearing the decks before a big hardware announcement perhaps?

BTW, Europeans think like Europeans, or at least not like Intel!  The microarchitecture exploits published last week were all discovered in Europe.  Kudos to the following:

This work was supported in part by the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 681402).

This work has been supported by the Austrian Research Promotion Agency (FFG) via the K-project DeSSnet, which is funded in the context of COMET – Competence Centers for Excellent Technologies by BMVIT, BMWFW, Styria and Carinthia.

The Graz University of Technology team would also like to thank Intel for providing a generous gift prior to the start of this research project, funding part of this research.

This research was partially supported by the Research Fund KU Leuven. Jo Van Bulck is supported by a grant of the Research Foundation - Flanders (FWO).
