I've been working fine with Mojave 10.14.6, most devices work like: 
	Wifi (intel with itlwm.kext & Heliport) 
	LAN (Intel) 
	Audio 
	USB ports
 
	They do not work: 
	Trackpad 
	Brightness controls 
	Micro SD reader 
	------------------------------ 
	I want to know what is the procedure to update to Big Sur, hoping that everything works without problem. 
	What are the steps =? 
	My configuration is based on Clover - Olarila
 
	 
	Thanks
