NVMe native support in 10.13

[RehabMan]

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.

You are booting the installer from USB?
Or something else?
If booting the installer from USB, use a USB2 stick, try all USB ports, and USBInjectAll.kext may be helpful.

Your Samsung 950 Pro (144d:a802) should work natively, but reaching the installer via boot from USB is not related to NVMe.

Also, you will likely need SATA-100-series-unsupported.kext (preboot.log shows unsupported SATA controller 8086:a103).

With dual GPU, make sure you read here:

I have the exact same output on a MacBookPro late 2013 with a Toshiba nvme (+ adapter). Battery life is substantially lower than with the stock Apple ssd, suggesting that power management with 3rd party SSDs is not implemented (yet?)

I have the exact same output on a MacBookPro late 2013 with a Toshiba nvme (+ adapter).

Why would you expect it to be different?

Battery life is substantially lower than with the stock Apple ssd, suggesting that power management with 3rd party SSDs is not implemented (yet?)

Quite possible.
Or the SSD you're using has substantially more power draw than the original Apple device, even if PM is implemented.
