Can I choose or downgrade macOS on a refurbished Mac?
You can't pick the macOS before you buy. The seller installs it, and most install the newest version the Mac supports. Once the Mac is yours, you can install an older version, but never one older than the macOS the Mac shipped with. RefurbMe lists that floor as the Default macOS under Product configuration on every Mac product page. Plan on starting from an erased disk, so back up first.
