Hi all Just replaced my old 2007 Imac for the 2015 (late) 5k - lovely piece of real-estate might I add. Couple of questions: When I first switched on and registered I proceeded to connect macbook pro to Imac and transfer everything over. 111GB took me 1hour and 35minutes averaging 12mb/s to 18mb/s which is clearly not right for thunderbolt 2 connection. Any idea how long this task should of taken, also did another brief transfer today - 14.64GB/8 minutes. First time using (browsing) and noticed the fan was audible but when played a Youtube clip it went ballistic and very hot so shut it down albeit it hasn't done it since but when doing say Word/Exel docs or general browsing I can hear the fan (Left side bottom corner) only faintly but nevertheless still audible - is this normal. Thanks in advance.
