2. Update macOS Big Sur directly from Catalina
Once it restart my mainboard can't detect internal hdd EFI anymore not sure why but I still have same EFI (clover 5126) on my usb so I use it to boot into Big Sur installer
Update went well but still can't boot into internal hdd EFI so I have to add it via Clover shell by follow
this guide
Wifi card, USB Bluetooth Sound, Alpine Ridge Thunderbolt 3 work just fine.
The only thing I need to do is map USB by follow
this guide as my usb port not working properly on Big Sur
I don't have time to try OC yet but I'll definitely move to OC as everyone recommended.
Updated:After upgraded to Big Sur, I can't install any app updates from the Mac AppStore right now .. still finding solution to fix it
