Hi, thanks for the reply, answer to your questions:
1. No, it's a cheap wireless keyboard + mouse combo i bought specially for this, because the touchpad and keyboard doesn't react on installation screen. Also it's a not a Surface Pro, it's a Surface Laptop 2, this is the product page with tech specs: https://www.microsoft.com/en-us/p/surface-laptop-2/8xqjkk3dd91b?source=lp&activetab=pivot:techspecstab
2. Yes it is a I2C device, i remember seeing it in Device Manager on Windows, but I didn't take screenshots of the I2C devices since there were a lot of them. Should I delete Mojave and install Windows again for this?
3. I'm not sure
4. I tried a few layout ID's, when I try to play a youtube video I only hear soft static sounds. I'll try the rest later.
