NVMe native support in 10.13 with me, no kext hack
Yes. This has been known for some time in the betas...
Certain devices still need a patch (as covered in my patch-nvme github README).

Does anyone know if there is power management with 3rd party NVMe SSDs on High Sierra? I switched back to AHCI from a Samsung 961 on Sierra because it wasn't worth the power use or heat (which translated into the fan running all the time). Definitely like to know the answer before I plop down the $$ for one.

Some clues:

Certainly looks like it will make the attempt but I don't know how that compares to what was going on before. Thanks for the info tho.

Probably we need to inject some properties to enable it.
It may also be conditional on queries to the device (compatibility/NVMe spec issues/Apple specific checks).
Look at an ioreg for Macs with NVMe devices.

Hi rehab, i have this error with nvme, at loading still stops at 60%-65%,,even if i tryed usb 2.0, i tryed all the ports, the error still waiting for root device is cause of the appleNvme assert error, it shows in the photo that can';t root, and exitting file cause of the nvme error. I used -v, and it tells: AppleNVme assert failed, i have all photos attached.

"Problem Reporting" files are incomplete (you forgot to press F2)
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

OK i attached the correct clover folder with fotos of the error. In the first foto is in -v mode, and it tells: still waiting for root device (tiny letters, is 4k display).Second foto is the progress just before it stops on the first foto. Bios settings: In the third foto are bios settings. UEFI boot mode; Secure boot:disabled.
