My Late 2015 iMac 27" 5k Retina came Thursday afternoon, did unboxing Saturday morning and migration of nearly 2TB data now … show 11 hours to do it.
I’ll give impressions after using for a few days.
Box in a box packaged:
VESA mount applied by Apple, I transfer the arm specific bracket to the new 2015 iMac on left, the old 2009 iMac is on right
Late tonight it should be done migrating 2TB, my ext 2TB HD has firewire 400/800 and USB 2.0, not 3.0, and the new iMac has no firewire so slow USB (45-ish MB/s)
now it’s slowed down to 28MB/s and 15 hours left … ugh USB 2.0 slooowwww.
