I just received my rMBP 2 days ago, and it is not having some problems with the trackpad. Out of nowhere, the trackpad just started to do things on its own. It moved around and clicks stuff randomly, making the computer unusable. It came with Mountain Lion installed, so the software update that Apple put out for Lion is already in it (I would hope (I tried the update and it won't let me instal it anyway)) I have now disabled the trackpad and am using a mouse to operate the computer, but I'd like to be able to fix this problem ASAP. Have any of you guys experienced this type of behavior with your rMBP trackpad? Has anyone had any luck trying to fix it? I have a feeling that it is a hardware problem rather than a software issue. Any input would be awesome!
