Does macOS High Sierra support NVME SSD natively?

[RehabMan]

Yes, I know, I was writing about running Plextor on 10.12.x. Sorry for misunderstanding.

A bit off-topic here (this is in High Sierra forum).
But, you can use patch_nvme.sh (from my github) plus the correct KextsToPatch entry in config.plist for Plextor preferred block size (just don't forget to change Name from IONVMeFamily to HackrNVMeFamily).

PLEXTOR PX-512M8PeGN in High Sierra and Sierra need same patches.

Adding only "IONVMeFamily Preferred Block Size 0x10 -> 0x01" does not work. On both systems.
