This site will help collect and show the temperatures of Apple Macintosh computers using the new processors by Intel. All new computers that haven't faced the trail of time will have problems and issues that can make users mad and furious. As with the new MacBook Pro machines where were, and still are, problems with heat dissipation. After scouting forums and help sites for information about what temperatures I can expect on a new MacBook, but that turned out to be harder and more scattered than I first imagined. That's the main motive behind this site and it didn't take too long to setup as I had the base code handy from another site. -
