I think that my 4 month old rMB might have a faulty haptic motor. I'm not sure how to explain this, but my trackpad does not give me the same feedback that it did the first months I had it. I feels like it barely works, and yes my settings is set to "firm". The trackpad works as normal, except I can barely feel the response. I've tried reinstalled the OS with no luck. Have anyone experienced this, or even heard about it? I live in Norway so I can't just walk into an Apple Store and check the problem. Warranty or not? Thanks in advance!
