Late 2012 Mac mini macOS Recovery
Hi, I was getting Mac mini ready for resale. My mistake was I erased too much I think. I erased Macintosh HD and Macintosh HD - Data. I downloaded macOS Recovery Catalina to external HHD.
What is the correct procedure to move MacOS Recovery form external to Mac mini. I don't want to mess things up. If there is a better way to fix this goof please let me know.
Thanks in advance for any info.
