Hi everyone,
a request for you..
I have a macbook pro 11,3 (mid2014) (original sad apple 512gb) with Mojave now but i don't like.
I would to come back to El Capitan but more fast and would more space on my ssd
For this reason i bought an SSD SB-rocket 1tb and an adapter NvMe to AHCI and an external case for nvme to usb
I know that nvme works from 10.13 (high sierra) but I read already if the possibility to rewrite with a patch the kext.

I don't understood how it work and how I can do. but i would to do.

Until now I installed el capitan thought the external sad case because when I try to insert and reboot with (cmd+r) disk utility didn't recognize my ssd.
How can i do?

It seems you can't run boot El Capitan on a NVMe SSD on a retina MacBook Pro.
I've already tried the method of patching the kext but it didn't work, and I tried it with a proper 4K-formatted NVMe drive

What work is that you can run Sierra (10.12) on a Sabrent drive.
But Sierra (10.12) needs a 4K formatted NVMe SSD : not all NVMe SSD can be formatted in 4K blocs but the Sabrent rocket can.

So you first need to set it to 4K blocks, which has to be done with the nvme-cli command (you can do it while booted on a USB key with any linux on it).
