How to recognize your MacBook model?


Portable Macs have their model name written right under their screen, except for those released between 2012 and 2016.

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

Height and weight

The MacBook is the smallest of Apple computers. The MacBook Pro is slightly thicker than the MacBook and MacBook Air (feel free to read our comparison of the 2 models). Older models are much larger and heavier.


The MacBook Air is only available in Space Gray, Gold and Silver while the MacBook was offered in Rose Gold, Gold, Space Gray or Silver.

The MacBook Pro is sold in Space Gray or Silver.


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

The MacBook Air has 2 USB Type-C / Thunderbolt 3 ports, its predecessor models are recognizable by their MagSafe port, two USB 3 ports, its Jack output, its unique SDXC card reader and its Thunderbolt 2 port.

The MacBook Pro 13-inch has, meanwhile, 2 Thunderbolt 3 ports and the 15-inch one (withdrawn from sale) has 4 Thunderbolt 3 ports and a jack. The 16-inch MacBook Pro has 4 Thunderbolt 3 ports.

The latest MacBook Pros are equipped with the TouchBar, which is placed just above the keyboard.

Here are some clues to help you identify your desktop Mac:


The iMac and the iMac Pro are the only desktop computers with an integrated display. They are each 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, or more than a billion colors supported. Entry-level 21.5-inch iMacs have a standard screen.

Height and weight

IMacs released before 2009 have a smaller screen (20 or 24 inches), those released earlier are even smaller (15 and 17 inches). Since 2015, the design of the iMac has been refined, to no longer be more than 5 mm thick. If your iMac is thicker, then it must be older than 2015.

The Mac mini is, meanwhile, the most compact of Apple computers, the most recent measures 19.7 x 19.7 cm and 3.6 cm in height.

The latest generation Mac Pros measure 25 cm, they are twice as small as their predecessors.


If your iMac is white (or any other plastic color) then it is older than 2007, since since their casing is aluminum. In 2005, when Apple launched the Mac Mini, it came in white and silver gray.

Their design did not change until 2010, it is now in aluminum. And since 2011, Apple has taken away the optical drive. In 2018, the Mac mini took on the color silver gray.

In 2013, The Mac Pro was completely redesigned. If yours is black and has a cylindrical shape then you have the most recent version. If it is shaped like a rectangular aluminum block, then it was released between 2006 and 2012.

External ports

Next-gen 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 a 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, by its optical drive slot.

Since 2018, the mac Mini has 4 Thunderbolt 3 / USB Type-C ports, one HDMI, two USB 3.1 and one Ethernet.

Mac Pro, before 2013 (tower): Its serial number is on the back panel of the computer, near the video ports.

Mac Pro, late 2013 (cylindrical): The serial number is listed on the underside of the computer.
