Hello, I am writing through a translator, so I apologize in advance. Faced ff800 patching problem. The patch does not work on imac2019 os catalina, I tried it on an old macbook pro 2008 os el capitan, the patch starts, but at the end it gives an error D0000000. at the moment the firmware is ff800 2.66, the drivers have tried everything that is available on the site. Help, the work is worth (((
