Still failing at upgrading to Sonoma from Monterey. The current tack I've been doing is taking the EFI (OC 7.4) out of my working Boot Disk and copying it into a USB install disk with Sonoma on it, and the use HackinDROM to update to 9.9. Everything seems to work, but then I get the black "NOT" screen on booting the installer.
