I have 2018 15" MBP. It seems with 10.14.2, I can not use the bluetooth keyboard on startup. It was the same problem with Mojave 10.14.0. Then with 10.14.1, it was fixed. I could login at the startup screen with my bluetooth keyboard. With 10.14.2, once again I can not use bluetooth keyboard to login as it does not register at all. Only after I have login, I can use the bluetooth keyboard. Anyone else have this problem?
