Hey all, Just wondering if anyone else has noticed a sizeable increase in the amount of heat generated by their MacBook since the PB yesterday? I have a MBPr late '13 which ran cool and absolutely silently (ie. fan hardly ever kicked in) with Mavericks, and is getting too hot even to hold at times. I have been running Logic, but it was even happening last night while only using Safari. Is this the type of thing to expect in beta phase or is it something to be concerned about? Ta.
