My first MacBook Pro retina (2.7/16/768) had a major fan issue. The rpm would go up to 9000 each. In addition, some initial install files were corrupted. Apple nicely replaced it. One week with the new one started freezing constantly. Usually at around 30-50 minutes. The fans go up to about 3800, and run way too frequently at that speed. I have an appointment at Genius Bar tomorrow as Apple Care can't resolve this. Has this happened to anyone else? This is my first apple computer. It's a great machine, but these issues are just ridiculous for something I paid close to $4000 for.
