    Upgrading 2008 Mac Pro 2008 3,1
    I have attempted to upgrade my Mac Pro with a PCIE card and NVME SSD to improve I/O performance.

    The Mac is running High Sierra via the proven Dosdude patch and works fine when booted from the internal WD hard drive.

    After configuring the new NVME SSD (Samsung 960 Pro) with the new AFS I tried to clone High Sierra from the WD HD to the new SSD via Carbon Clone copier V5. While the clone was reported as successful and the disk “bootable” I cannot get the Mac to boot successfully from the SSD. I get a blank screen with no progress bar.

    I also tried a clean install directly to the above SSD using the Dosdude High Sierra Boot disk with the same result.

    Constructive advice welcome!

    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
