i found the issue, believe it or not its related for installing the realtek_hd driver on windows, not sure what is the relation but removing the driver fix the issue.
am also in the same boat, any help is deeply appreciated.
opencore v0.6.4.
PS:
the efi folder also has the opencore debug log, if there is a way to collect more info of the issue, plz do tell.
i used to have a 4x4g ram kit "Corsair Vengeance CMK16GX4M4A2400C14R" which was working perfectly without any issues but sadly the ram modules started to hang a bit so i decided to change it to a 1x16gb ram "CRUCIAL Ballistix BLS16G4D32AESC".
the problem is the machine became very sluggish...
this means your usb wasnt correctly formatted, the efi drive should be available whether u used clover or not, clover simply put some files on it but if the dirver it self is not there then you should reformat the usb properly...

the panic is too long and a ss wont help but even better, i've been trying to find a way to save the boot log "panic or normal" to the efi but dont know how :( , "var/log" have **** load of logs and i dont know why one is related to the boot.
is there a link u can direct to do that ?
using single user give panic , single user & safe mode give auto-reboot.
btw do u by any chance have a vga monitor somewhere u can test ? am starting to suspect that its an issue with new OS and the vga-to-dvi converter
i honestly not sure what is the difference between using 6.1 or 14.2 "the current for El Cap" other than 6.1 was the one i was using on El Cap USB, i've included my current config incase u may need it.
sorry this it the only machine i have, for the IOReg not sure what u need but i have AIDA64...
first happy birth day to your son :headbang:
second i added the 2 patches of pika and tried all the frame buffers with (4) connectors but nothing worked.
however i noticed that none of the above list have the correct connectors type as the 270x which is "2x Dvi, HDMI, DP" and it seams that one...
yeah already done, btw i was thinking of flashing my card with https://www.techpowerup.com/vgabios/151253/sapphire-r9270x-2048-131105-2 bios, what do u think ?
already on, but about whatever green note, this is new, i will try with CSM off.
deeply appreciate it , but sadly it didnt work.
without "inject ati" it give panic
with "inject ati" same old black screen.
