    Seems problem with NVMe kernel extension. Try remove 960evo from Mac and boot again.
    P.S. I hope you dont trying 960 as boot drive?

    Possible reason of problem (but not sure for 100%):
    your wrote in another thread, that you install Angelbird software before. AFAIK it content TRIM enabler patch for IONVMeFamily.kext. And installation of macvidcards NVMe driver cause this error. I think you should uninstall Angelbird patch, or restore original IONVMeFamily.kext

    P.S. I'm not sure, that you can uninstall Angelbird package. Maybe you have to reinstall macOS.
    But dont install this software any more.

    P.S.2 PX1 is just mechanical extender and don't need any software to work

    I see, and you maybe right, but still, why can i not access the recovery mode? That would solve everything...

    Btw, the IONVMeFamily.kext file is dated september 2015, does that mean its the original?

    Did you try access recovery mode before this error?
    I have heard about some issues with Nvidia card and access to recovery mode.

    Its mean nothing. Date can be changed.

    My advice - find another HDD, put it in Mac and make clean OS install. Install macvidcards driver and test it. If it work good, then make changes on main system.

    It turned out the Nvida card was the problem, reinstalled my old Amd, and restored to day before, and after reinstalled the Nvidia again.
    So much for stubbornly keeping that old fart, new imac comes tomorrow ;)
