I'm wrestling with an odd problem in the lab and hoping someone has some insights. I have a 2012 Mac Mini (6,1 - Core i5-3210M) and I'm unable to get Alma installed on it, as I can't get the installer to actually boot. Thus far, this is what I've tried:     - Alma DVD or Boot ISO on USB stick: Mac can see the stick as bootable, but selecting to boot results in a black screen.     - Ventoy with Alma DVD ISO: Booting in "normal mode" results in the same as above (black screen). However, booting in "grub mode" gets me to the first installer-select screen (install/validate/troubleshoot). Any option selected from there, however, even "install in non-graphical mode", results in a black screen.

Hi, I had the same problem a few years back. I solved it using rEFInd. I wrote a blog article about it on my tech blog (in french) : https://blog.microlinux.fr/refind/

Merci! That got me a little further — reFIND works, it finds the EFI grub image on the Alma USB stick, and it attempts to boot it. Alas, it gets no further than that: I get a message about booting with default grub options of '', and then a white cursor, and nothing further.
