Installing the OWC 'Upgrade' hard drive was easy following their instructions to clone the original Apple internal hard drive and then install your hard drive provided that Mac OS was High Sierra+, however after 10 days I get a brick with a crossed out circle and I had to reinstall Apple's original OEM. The second generation of OWC's Aura SSD replacement does not appear to be any more reliable than the first generation for Macpro 6.1 (2013).
