Wed 10/22 Soldered to the Board

Firmware

The following list details the first Macintosh in its form factor to have its memory soldered to the logicboard.` Every Mac that has followed in that form factor has continued in this trend. Can you see a pattern developing?

  • MacBook Air (Mid 2008, MacBookAir1.1) 2 GBs
  • MacBook Pro (Retina, 15-inch, Mid 2012, MacBookPro10.1) 8 or 16 GBs
  • MacBook Pro (Retina, 13-inch, Late 2012, MacBOokPro10.2) 8 GBs
  • iMac (21.5 inch, Mid 2014, iMac14.4) 8 GBs1
  • Mac mini (Late 2014, Macmini7.1) 4, 8, or 16 GBs

Only the 27-inch iMac, and Mac Pro still have user-replaceable memory, and even these models include proprietary parts that are departures from their predecessors.2 To anyone who thinks Apple’s move to integrated components is a fad soon to be reversed, think again. The days of the Macintosh II, and “user-upgradable everything” are over. If you see your computer as more than a sealed appliance, you are no longer Apple’s customer. But you are missing out on a great Mac.


  1. The iMac (21.5-inch Late 2012, iMac13.1) had 8 or 16 GBs of RAM in 2 non user-servicable slots, located behind the logic board. 

  2. Both the current 27-inch iMac, and Mac Pro contain proprietary storage and graphics, when previous models did not.
