The FireWire ports were still limited to 2 ports however, the second FireWire “400” port was upgraded to a FireWire “800” port.

Common questions

Is MA876LL/A the same as A1224?

Not exactly. MA876LL/A usually points to a specific retail configuration, while A1224 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What iMac is model A1224?

A1224 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 2133 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.
