does the Ignition SKU still exist for modern platforms? I believe Apple is using the Slim SKU (win-raid.com/t596f39-Intel-…)

EPIC JAILBREAK: Introducing checkm8 (read "checkmate"), a permanent unpatchable bootrom exploit for hundreds of millions of iOS devices.
Most generations of iPhones and iPads are vulnerable: from iPhone 4S (A5 chip) to iPhone 8 and iPhone X (A11 chip).

STOP using single-purpose instructions
MOV is Turing complete
XOR is Turing complete
SUB is Turing complete
(CMP)XCHG is Turing complete
JMP
ADC is Turing complete

it's probably this: github.com/Goldfish64/Aud…
though if you just want to add NVMe boot support, you don't need Clover, you can create a driver entry for NvmExpressDxe from the UEFI shell (to load it at boot):
bcfg driver add fsX:\path\to\NvmExpressDxe.efi "NvmExpress"

FakeSMC (which only does PMIO emulation) still works in the 10.15 betas, so...
though Ivy Bridge Macs were the first to use MMIO SMCs, so I wouldn't be surprised if PMIO support is dropped soon (support for any Mac before Ivy Bridge was dropped in 10.15)

1) what @coolstarorg said; Ivy Bridge (and newer) Macs use MMIO to communicate with the SMC
2) this has been tried before (wasn't released though: insanelymac.com/forum/topic/31…), I don't think the performance was that good
