    Anyone having issues with the fans constantly running under PB1? Looks like Mail is consuming a ton of CPU, and the fans are always running. If I close/quit Mail and restart its good for a little bit, then starts up again.

    Thanks in advance...

    I have noticed that my rMBP runs a lot hotter under PB1. Its a little weird. I know its a general rule that greater heat isn't good for your computer in the long term so I don't know if I should revert back to yosemite
