I have been using my new MBP for about 2 weeks now. Today all of a sudden the left arrow key has become very hard. Applying the same amount of force as I do on any other key on the left arrow does not press it. I have to really bang it hard to get that key press registered. Phoned Apple and have got an appointment booked for tomorrow at an authorised Apple service provider. Did anyone face similar problem with their 2017 machine?
