Software update macbook pro

They don’t even work inside the restore menu. However, the computer works perfectly using external keyboard and mouse. It started working on its own one day and stopped again.

Did not find what they wanted? Try here

Yes, all the way down, not sleep or logging out. Press the power button and then press command-option-p-r.

I am typing on the keyboard!
