Unable to enter password on iMac Pro login screen

What keyboard are you using...?

If you have a rechargeable Apple Magic keyboard, plug it into the iMac Pro using the supplied charging cable.

If you have an AA battery powered Apple or aftermarket wireless keyboard, dig out or borrow a USB keyboard and use it to login and re-pair the wireless keyboard.

If you can't connect your Magic Keyboard, Magic Mouse, or Magic Trackpad to your Mac - Apple Support
