From all these excellent links as well as what I’ve read elsewhere, I’ll take big odds on Apple rolling its own ARM processors for Macs. My trusty and much loved MBP has begun its slow but inevitable journey to that great Apple graveyard in the sky. Though I know it will be best to replace it with a new mini or MBP, because I bought my equally beloved 9600 literally 6-8 weeks before Steve Jobs announced that OS X would only run on Intel Macs. So I’m hesitating that I’d once again be left out of the latest and greatest software and upgrades and hoping Apple will begin rolling its own ARM Mac processors sooner than later.
Reports that I’ve read over last few days indicate that Apple took significant steps to prevent macOS interaction with the Converged Security Management Engine (CSME) that has these flaws. Intel released some test software for Windows and Linux, but not macOS. I used the Linux tests in Terminal with Mojave today. The primary test for the newest processors failed and the legacy test indicated that Apple had not provided the necessary driver to access CSME, so couldn’t complete the test.
