This Clover EFI is working on Catalina, but there are some issues. I'm facing unexpectedly shutdowns, either using the battery or with charger plugged in. Also, as mentioned before, keyboard isn't working, but something weird happened: i closed the laptop, and after few minutes, opened again, and the keyboard suddenly worked. I tried to install XCode, and the laptop became so sloww, and then turned off. I think that was something related with temperature, because the power button doesn't worked until the laptop was cold enough. Should I upgrade to Big Sur in order to use this EFI?
