I've built Hackintoshes so I'm familiar with kext replacing and what not, my idea was more that Apple could do something to limit apps/OS from running on anything that didn't have a t2 chip and it might be difficult to get around, like OSX on exotic or AMD chips can be a bit of a pain. Haven't used one in a few years though. Also the chip stuff is out of my realm of expertise.
The Intel transition was officially started with 10.4.4, IIRC, and the last version of Mac OS X that PowerPC Macs could run was Leopard. Mac OS X 10.7 dropped Rosetta, meaning all software had to be Intel-only. I know that by OS X all system binaries were Intel only, without a PowerPC slice.
Right, you're replacing kernel extensions with patched ones then? Problem is, intel is intel, so again any such limit could be patched.
I understand your concern, but consider it this way: The only real mitigation Apple might have is to offload certain critical functionality to the ARM chip, and even then, they would have to drop support for all macOS hardware without T1/T2.
True; it would be as simple as crucial parts of the kernel being targeted to ARM (to run on the T2.) Good luck patching around that without embedding an ARM VM kext to simulate the T2; and then good luck getting that to be at-all performant.
Well, it's easier to bypass a software check like that than it would be to create a hardware check like the T2. It's unlikely to hurt hackintosh anytime soon.

Was just a thought I had.
