Hello.
it seems I was wrong by not reformatting the disk.
formatted, started to install, reboot and everything started.
now the installation is going on.
but there is one point.
ambassadors for opening the configuration and unchecking the checkboxes - the graphical interface in the bootloader disappears.
I use opecore configurator
UPD:
and it works! wifi works great!
but bluetooth does not connect anything.
and the trackpad does not work.
and it gets very hot
well, i take clean OC 6.8, then add and replace everything from archive by link.
finaly i add intel kext and replace config once again.
setup start, but after first reboot and boot from ssd ctuck on this (in attach).
and so in a circle...
my EFI folder here
