Common questions

Is MB871LL/A the same as A1289?

Not exactly. MB871LL/A usually points to a specific retail configuration, while A1289 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What Mac Pro is model A1289?

A1289 is the Apple A-number shown for this Mac Pro family. Use the order number, EMC, and model identifier on this page to narrow the exact configuration.

What does EMC 2314 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?
