About this iMac

The Apple iMac Intel Aluminum released October 2012 was another step in creativity in the world of computers. A number of more conventional features of a computer were absent – such a DVD drive slots and the FireWire ports that were traditional with the Apple iMac brand and new features appeared – such as the Thunderbolt port which allows for the passage of both visual and audio signal. The basic components of a computer such as the RAM were upgraded as this model had a 8 GB of 1600 MHz PC3-12800 DDR3 SDRAM which could be upgraded on purchase to a 16 GB RAM but not recommended for upgrade after even though it is a possibility. The USB ports were 3.0 ports. It also had a powerful graphics processor included with its NVIDIA GeForce GT 650M graphics processor with 512 MB of dedicated GDDR5 memory with a built-in FaceTime HD camera. This computer still stands tall among competitors and will continue to stand tall for a long while regardless of the amount of development that happens in the computer world.

Common questions

Is MD094LL/A the same as A1418?

Not exactly. MD094LL/A usually points to a specific retail configuration, while A1418 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What iMac is model A1418?

A1418 is the Apple A-number shown for this iMac family. Use the order number, EMC, and model identifier on this page to narrow the exact configuration.

What does EMC 2544 mean?

The EMC number is another Apple hardware identifier. It helps separate closely related models that may share a similar name, year, or A-number.

Can the RAM or SSD be upgraded?

Check the spec table for the exact configuration. Many newer Apple Silicon Macs have memory and storage integrated into the board, so RAM and SSD upgrades are often not practical after purchase.

What should I search if this page is not the exact configuration?
