Start Late 2014 Mac Mini From External Drive
I've read the post by Jack-19 (link below) titled "Use an external SSD as your startup disk with your iMac or Mac mini" but have a question. Does the internal have to be an Apple HD, or can it also be an Apple SSD. I have an opportunity to purchase a Late 2014 Mac Mini from OWC that has (per their description) "This machine comes with a 256GB Apple OEM/Factory Solid-State Drive". Anyone have one of these and has been able to boot off an external SSD?
