About this iMac

The Apple iMac Intel Aluminum released June 2014 had some uniqueness of its own from the other models such as the 802.11ac Wi-Fi which is backward compatible with the 802.11 a/b/g/n Wi-Fi. It had a non-upgradeable 8 GB of 1600 MHz PC3-8500 LPDDR3 SDRAM. The “thick-at-the-middle-thin-at-the edges” design remained the same in this release of the computer just as the late 2012 version. This computer had all the needs of this generation of computing packed into its 450mm×528mm×175mm and featured a lightweight of 12.5 lbs (5.68 kg) casing.

Common questions

Is MF883LL/A the same as A1418?

Not exactly. MF883LL/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 2805 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 macOS versions work with this model?

Use the model identifier, release year, and processor family from the spec table when checking macOS compatibility. Compatibility can change as Apple releases new macOS versions.

Is this iMac still worth buying used?

It can be, depending on price, battery health, memory, storage, and condition. Compare this exact order number and model identifier against similar Techable listings before buying.

How much is this iMac worth?

Value depends on RAM, storage, battery health, cosmetic condition, accessories, and market demand. Use the SellMac path on this page for a quote or use the identifiers here when comparing resale prices.

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

Search the order number first when available, then compare the A-number, EMC, model identifier, year, chip, RAM, and storage. The same A-number can cover more than one configuration.
