Find the correct model
Sometimes it is not so easy to determine exactly which computer model you have. Whether you're looking at an iMac or a MacBook Air is usually decided quite quickly - but how can you tell the difference between a MacBook Air from 2012 and one from 2013 from the outside? Both have the model number A1466 - but the internal components are not compatible. Also, you can't always rely on the information on the base plates, because for example the base plate of an A1370 11" MacBook Air from 2010 will easily fit on a 2015 11" A1465. Here are some tips on how to distinguish between the models.
MacBook Air 11"
The MacBook Air 11" is a rather small and handy notebook. It can be clearly identified by the imprint "A1370" or "A1465" on the bottom. Not readable anymore? If your MacBook Air has a case width of 30 cm, it is the 11" model.

MacBook Air 13"
The MacBook Air 13" is a very popular and handy notebook. There are three basic models: The original "original" with the model number A1237 or A1304, which can be recognized by the fact that there is a small flap on the side under which the USB, headphone and monitor connection is hidden. And the newer model, introduced in 2010, can be recognized by the imprint "A1369" or "A1466" on the bottom.
Here you can learn how the 13" models differ.



MacBook Pro 13"
MacBook Pro 13" was introduced in 2009 (although the 2008 MacBook Alu model can also be added) and continues as a model series until today. The models can be roughly divided into the A1278 from 2008-2012, the Retina series from 2012 to 2015 and the Touchbar series from 2016 and later.
