So I just purchased a brand new MacBook Pro Retina 15" 2.40GHz.


Randomly, when nothing but finder is open, the fans will spin at full speed.

I have opened every application on the machine including serato, ableton, photoshop, VLC playing a 1080P movie, iTunes playing music and youtube playing videos in 2 tabs - and the fans do not spin as fast at it does when nothing is open or running (confirmed with activity monitor too).


Secondly, once I eject a USB3.0 drive from the machine, I have to reboot the system before the drive can be mounted, or even recognized at all by the computer. (it does not even show up in disk utility till the reboot). this happens with 2 seperate USB3.0 external hard drives that work fine on other rMBPs. This happens with both usb ports too.


I have reset SMC, PRAM, ran all Apple updates as well as reinstalled the operating system (as well as booted from a known good system in target disk mode).
