The new Mac mini (Late 2014) has no upgradable Memory. Its 4, 8, or 16 GBs of 1600MHz LPDDR3 are soldered to the logic board. A suction cup is required to remove the Bottom Cover. Six T6 security screws are required to remove the Antenna Plate. Each security screw must be replaced before the Mac mini can be reassembled.
