Where do I find my Mac’s model number?

Turn the machine over: the number is engraved in small type on the underside, as an “A” followed by four digits. On an iMac it is on the back of the stand. The EMC number, which tells apart two machines sharing the same A number, is listed under Apple menu, System Information, Hardware.

Frequently asked questions

How can I be sure the part will fit my machine?

The model number engraved on the underside is enough in the vast majority of cases. Where one reference came in several variants, we say so on the part’s page. If in doubt, send us the A number and the EMC number and we will check before you order.

Are the parts new or used?

Both, and it is always stated on the page. A used part is tested and warranted exactly like a new one. On older machines, used is often the only genuine option still available.

What warranty comes with the parts?

Two years on every part we sell, new or used. Return shipping is on us if the part does not match its description.
