    Hello, everyone!
    I 've got some stuff: Mac Pro late 2013, Sonnect Thunderbolt EchoExpress3 and main topic Intel P3700 PCI express (x4) NVMe SSD.

    When my MacOS was 10.9.5 I am using a 3rd party driver and my SSD works well as second disk.
    Then I read that i a new MacOS 10.13.x NVME SSD disk is a native , and no more needed 3rd party drive. Also I can use a new version of software for my work. But when I install a new Mac OS my SSD gone away, and Mac OS always start with panic kernel message. I try to find out a 3rd party driver again, but every where is said that it no more needed :(. May be some1 can advise me how to return workable state of my P3700?

    Can you install clean 10.13 on internal drive with Sonnet disconnected? Make sure it updates Boot ROM. Then see what happens when re-attaching Sonnet.

    Thank you for advice!
    I solve my problem with deleting some files at Library/Extension not only in System/Library/Extension. Because kextunload says that nothing being loaded.

    But I receive next issue, with native apple driver read/write speed of SSD drop down from 1,5 Gbyte/s to 0.4 Gbyte/sec :( . Like NVME instruction do not work well.
