Has anyone else had an issue that would cause your MBP or any other Macs fan to run at full speed due to the graphics card becoming really hot when idling or even light work? I downgraded back to 10.10.5 and don't have an issue. Im running 16gigs, with a 512 samsung 840 pro ssd, 2.6 I7. Im not sure if this is just my problem or if others are as well.
