Yes .. it should be on mirror.centos.org now .. you could change the repo where your updates come from.Ã OR

I just did yum clean all yum update

did it, or maybe just showed up.
I applied the update (yum update), rebooted and... no boot.Ã Just a blank screen.
Hardware is a Mac-Mini :-(
This is not an essential machine, so I could re-install (from netinstall) if you think it's worth the effort.
Or what?

You just need to reinstall the kernel and it should work.
Sorry for being so ignorant, but I don't understand "just reinstall the kernel". I don't know how to translate that into a specific yum or rpm command.
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:
- boot using a working USB/cdrom/netboot path and installer
- choose the rescue mode
- 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.

I don't have any access to a Mac Mini to help further than this general help: First I would search google for "how to obtain model version info on mac mini"

Then depending on how the mac mini is being booted (using the windows compatibility mode or some other method) I would look for howtos on how to update the firmware.
After that it is time to learn the Mac magic key boot sequences. The Mac isn't exactly a PC and its UEFI does not have a standard menu front end like many PC UEFI.
