Hello, for the past week, the fan of my 2010 MBP sounds like a vacuum cleaner and whenever I stop typing, there is a long pause before I can type again. Is it a sign that the machine is dying? We don't know when Apple will release a new MBP for sure. Can I try out the MBP 2017 and if I don't like it return it to Apple for a full refund? If that is the case, how do I remove all data from the SSD?
