I think this might be jumping to conclusions too early. It's certainly possible - the T2 has been around for almost six years (and has been in every new Mac for four), so anything that doesn't have the chip is already well into it's lifecycle. It stands to reason that Apple is going to want to leverage the T2 in Macs that have the chip, but this is a pattern of releases you'd expect if Apple is building out more security feature support for Macs with T2. I'd say wait to see if the updates come to older Macs - it's likely they're still testing whatever fudges need to be in place for non-T2 models to make up for the missing functionality.

  I didn't know this and it's pretty surprising to me. In any case it's all the more reason I don't think it changes anything here. I'd be really shocked if they outright dropped support for non-T2 Macs at this point in their lifecycle, especially if they were selling new machines a year ago without the chip. It just stands to reason that macOS would become more dependent on security hardware over time and they would fudge whatever they need to separately in order to keep the older models working through their support life. I've no insight into macOS internals but I'd suspect that by now there's some kind of software T2 chip in the kernel for these older Macs that performs as much as possible of the same function minus the tamper protection and hardware acceleration - and that they're pushing updates for that separately. We'll find out next week at WWDC I guess.

This is completely inane speculation. "All the T2 Macs use the same firmware version......and therefore non-T2 Macs won't be supported in MacOS 12". Zero proof, but here we are, rewarding this drivel with thousands of page views and hundreds of comments

  I probably wouldn’t be so harsh, but I agree. This is uninformed speculation based on essentially a hunch about nothing significant. Personally I don’t see why it deserves attention, but I think most of what I see on the internet is nonsense, so what do I know?

  I take this article as "random guy on the internet says random things" to get people riled up. Who cares what this guy says? Next week Apple will spell out what's supported. Sheesh.

> the T2 has been around for almost six years (and has been in every new Mac for four) You're mixing something up here. In October 2016 (so less than 5 years ago) Apple started offering the first devices with its T1 chip (MacBook Pro 2016). The T2 chip debuted in the iMac Pro 2017.
