My MacBook Pro (2014) can not start after downgrade from macOS 10.13 to 10.12 via USB.

I don't known why I had clover on my MacBook. Right now, my MacBook starts up with a light screen and doesn't show anything. Keyboard caps lock and USB don't work.

  • Please add any step you already performed (SMC/NVRAM reset etc) to solve your problem to your question and not in the comments! Please remove your comments afterwards. – klanomath Jul 16 '17 at 15:31
  • We know even less than you why Clover is installed on your Mac! So you have to explain it to the community... – klanomath Jul 16 '17 at 15:34
