In this tutorial, we explain how to identify the model of your Mac, how to find its serial number and the technical characteristics of your computer.

Identify a Mac

Apple has developed 6 models of Mac, they are distinguished mainly by the size of their screen and the power of their processor.

Three models are laptops, these are the MacBook, MacBook Air and MacBook Pro.

The other three are desktop computers, the Mac Mini, iMac and Mac Pro.

To identify exactly which Mac you have, turn it on and click on the apple icon on the top left of your screen. Then, from the drop-down menu, click About this Mac. The window that appears gives you the technical details of your Mac.

The screen, size, colour and external ports also identify Mac laptops and desktop Macs.

Which portable Mac do you have?


Mac laptops have the name of their model written just below their screen, except for those released between 2012 and 2016.

It can also be distinguished by the quality of the screen, for example, the MacBook Air and MacBook Pro, the older, do not have the Retina display (LCD high resolution).

Height and weight

Today, the MacBook is the smallest of Apple computers.

The MacBook Pro is slightly thicker than the MacBook and MacBook Air.

Older models are much bigger and heavier.


The MacBook Air is only available in sidereal grey, while the MacBook is sold in golden rose, gold, sidereal grey, or silver.

The MacBook Pro has a sidereal grey or silver colour.

External ports

If your Mac notebook only has a USB-C port for charging and connecting peripherals, then it’s a MacBook.

The MacBook Air is recognizable thanks to its MagSafe port, two USB 3 ports, its Jack output, its unique SDXC card reader and its Thunderbolt 2 port.

The 13-inch MacBook Pro has 2 Thunderbolt 3 ports.

The 15-inch MacBook Pro has 4 Thunderbolt 3 ports and a Jack plug.

Some MacBook Pro is equipped with the TouchBar, it is placed just above the keyboard.

Which desktop Mac do you have?


The iMac is the only desktop computer with an integrated display.

It is available in two sizes 21.5 and 27 inches. Most iMacs sold in recent years have a Retina display with a resolution of 5120 x 2880 pixels, which is more than a billion colours supported.

Height and weight

IMacs released before 2009 have a smaller screen, 20 or 24 inches. The screen of the previous iMacs are even smaller, 15 and 17 inches.

Since 2015, iMac’s design has been refined to a mere 5 mm thick. If your iMac is thicker, it is necessarily older than 2015.

The Mac mini is the most compact of Apple computers. The newest is 19.7 x 19.7 cm and 3.5 cm high.

The latest-generation Mac Pro is 25 cm, and are half the size of their predecessors.


If your iMac is white (or any other colour of plastic), it is older than 2007 because since their case is aluminium.

In 2005, when Apple launches the Mac Mini, it has the colours white and silver grey.

Their design evolved only from 2010, it is now in aluminium. And since 2011, Apple has removed the optical drive.

In 2013, The Mac Pro has been completely redesigned. If yours is black and has a cylindrical shape, you are in possession of its most recent version. 
If it has the shape of a rectangular aluminium block, then it came out between 2006 and 2012.

External ports

The new generation iMacs feature an SDXC card reader, USB 3, Thunderbolt 3 / USB-C and Gigabit Ethernet outputs.

Note that iMacs released before 2017 have a Thunderbolt 2 port, not 3.

The latest Mac mini is equipped with two Thunderbolt 2 ports, four USB 3 outputs, an HDMI and Ethernet output and finally an SDXC card reader.

You’ll recognize a Mac mini, released before 2011, to its slot for the optical drive.
