Hello, my pc is arrived, I followed the 7490 Hervè's guide (bios settings, Catalina clover pack, and guide's steps) I'm esclude the DSDT file out EFI/Clover/ACPI/Patched and the installation is finished successfully (THANK YOU VERY MUTCH!!!!!!!!!!!). Now I'm finished the post installation and i found only 3 issues:
1 (for me is very important) microphone input and headset output won't work (latest AppleALC and CodecCommander Layout id 11)
2 I need remap some keys, cause the ALT is on Command/Windows place, and brightness fn+f11/f12 don't work
3 The system don't recognize any trackpad (i've only basic mouse movement) fix solution is copy all kext in L/E and rebuild the kextcache
In the attachment my EFI (i've only update the lilu, whatevergreen and applealc kext). Thank you in advance for your help.
