The iMac Intel 21.5" EMC 3068 was released in June 2017 as a lower-spec alternative to the 4K Retina Display iMac from the same year. The budget (comparatively) model comes with a 1080p display and an Intel i5 series processor. It has USB-A ports and Thunderbolt ports on the back for a variety of input options. You can identify this machine by looking under the stand for the model number “A1418” and the EMC number “3068.” The model number was shared by multiple iMacs, but the EMC number is unique to this version. If you open the System Information application in macOS, the computer will also be identified as the “iMac 18,1.”

At purchase, this iMac can be configured with 8 GB or 16 GB of memory. Surprisingly, this memory is not soldered to the logic board, but is actually upgradeable to a maximum of 32 GB.
