Thanks for the tips!
1. ACPI
In Clover Configurator I see only FixDarwin, no FixDarwin7 option. Removed FixHPET and FixMutex (don't know what exactly they do)
2. Boot
Fixed 20s boot delay, now is 5s. Legacy field - empty now
3. Devices
Nvidia filed looks like I can't delete anything there, grey digits I can do nothing with them
4. GUI
Removed all custom entries.
5. Kernel & Kext Patches
IOAHCIBlockStorage patch removed
Removed FakePCIID, switched to FakeSMC and it's plugins, removed Virtual SMC.
RESULTS - Nothing's changed in terms of boot, still the same slow boot + the black screen. Now my sound, bluetooth and battery sensor are not working
I am a bit noob at this, probably it's my mistake or I miss something.
