  1. Hi there! I'm trying to install High Sierra on my brand-new DELL all-in-one Optiplex 7770 following a "vanilla" path. I've prepared a USB thumbdrive with the latest (5070) Clover in the ESP and the usual "4.hfs" High Sierra Recovery image dumped into a separate 3GB "AF00"-type partition. I couldn't be able to get into the installer, since the root filesystem was on an unsupported USB3.0 port (my machine lacks any USB2.0 ports). Then, I created a 3GB temporary AF00 partition on the SSD and, using a custom EFI folder (found somewhere for a Z390 Aorus Pro), I was able to get the language selection menu in full 4k resolution... ...but... both the mouse and the keyboard (which have their dongle in a USB3.0 port) didn't work at all. Is there any kext or patch I could try for my machine? Thank you in advance! HS
