I agree it is a lot of shorthand because of expectations. In the end
we (the list) don't know what you have on your system or what state it
is in. In order to get that information to help we would need you to
try the following:
1. boot using a working USB/cdrom/netboot path and installer
2. choose the rescue mode
3. have the rescue mount the disks as local and chroot into the
system. << if possible have the system also bring up networking >>
Then
yum list kernel shim grub2 mokutil
It would also help to know which kind of Mac Mini it is (year, model,
firmware versions). Apple changes the internal hardware of these
things and how they boot so if there it may be that a particular model
is more affected than others.
How does one obtain that information? There's nothing written on the box.
