  • The new iMac announcements are great! I'm looking to replace my trusty late-2009 iMac. Do you know if the memory is user replaceable/upgradable? Or are we stuck with the same amount of RAM from the day we purchase the machine?
  • Same question.
  • @VTChamp - Looks like the outer casing and upgradability are the same as previous years.
    You CANNOT upgrade the memory in the 21.5 inch models. But, all the 27.5 inch models have 4 "User Accessible" memory slots for upgrading the memory. On top of that, the previous iMac officially supported 32GB of RAM, but you could actually put 64GB of RAM into it. These new ones now officially support 64GB of RAM. I wonder if we'll be able to put 128GB of RAM into them? :)
  • With the new Thunderbolt 3 ports will target display mode make a comeback?
  • Same question here! I would love to use the new 5k iMac also as an external monitor...
  • Anyone know how large the SSD portion of the various fusion drive options are?
