I appreciate the responses. Now, considering that I am running the system at left with Clover EFI bootloader R5119 and MacOS 10.15.7 (build 19H15), and I have a USB 2 flash drive with OC 0.6.3 and all its accoutrements plugged into the front USB 2 port of said computer, can anyone answer my question in bold print in post #32? If OC is working, what is supposed to happen after I pick "OpenCore" in my BIOS as my boot drive, boot on that, and then "pick" either one of my two SSDs or one of the Recovery options? Should a "good" OC flash drive open MacOS? Or not? Or what else?
