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.
