I have a solid state PCI drive formated APFS from Mojave.. currently i updated to 2012 Mac Pro 12 core and I can upgrade OS X to High Sierra.. but before I do that I want to format the PCI Flash Drive while in El Captain and use that drive instead to upgrade to High Sierra..
while in El Captain disk utility doesnt see the APFS drive
any ideas?
