    I'm using a clover installer on USB in conjunction with the HS Install app. I'm a bit confused about the EFI partition and whether that it is a bit of necessary code that is always present and created by the Apple installer or purely a Clover created hack that fools Apple software into booting on a non Apple machine.

    I've done several installs from El Cap onwards and the EFI partition was always created as part of the process of using UniBeast so I was wondering if the hack to disable APFS was disrupting the install. I've followed your instructions but only the one big volume is being created:

    Create bootable USB using UniBeast and boot from it choosing the external file on the USB
    Open Disk Utility and wipe SSD with HFS Journaled (creating large partition that fills SSD)
    Click install to add files to SSD
    Reboot with USB and choose USB installer to boot from again
    Run Terminal and do the xml change
    Reboot from USB and boot from (modified) installer on SSD
    Keep choosing SSD installer after reboots until complete

    This results in a working system and the file system being correct but just one partition on the SSD and no EFI or other partitions.

    Thanks for your help and any guidance is most appreciated.

    Tried another install same result. Screen grab of Disk Utility:

    Is this what you would see on a real Mac - IE no other partitions as the hardware is capable of natively recognising and booting from a Mac partition? I note that Windows installs routinely create several invisible partitions as part of a normal install.

    EFI partition is always created by Disk Utility when you partition a disk as GPT.
    You should not expect Clover to be automatically installed to it, nor for the EFI partition to be automatically mounted.
    You can read about how to mount EFI in the laptop FAQ:
    http://www.tonymacx86.com/el-capita...faq-read-first-laptop-frequent-questions.html

    Also, the EFI partition is always hidden in Disk Utility, so don't expect to see it there.

    Is there any hope of disabling TRIM on APFS drives in the future with a kext or something or is it too low level? Ideally I could have the speed of an NVME, the niceties of APFS, but skip the boot time required for TRIM

    It is probably possible to create such a patch. I haven't read about anyone doing it though. And the TRIM issue is not the only NVMe issue anyway.

    You will need to provide images that show exactly what you're doing.

    And thank you In advance

    Edit:
    i guess i fixed that out by running LS and CD command
    but what worked for my case is CD /Volumes/os2/"macos high.. .."
    then i used the provided command
    it worked

    374?
    ls -l /Volumes shows no volume named '374'.
