MagSafe 2 is thinner and was designed for MacBook’s released after 2009. The first edition of the MacBook Air also used MagSafe 1, but had a slightly thinner head. MagSafe 1 is slightly larger, and was introduced in 2006 along with the original MacBook and MacBook Pro. That’s if we ignore the different wireless MagSafe for iPhone (see above) of course! There are three different versions of MagSafe, conveniently known as MagSafe 1, MagSafe 2 and MagSafe 3. “The surface area of two magnetically attracted halves determines the number of magnetic flux lines and therefore the holding force between them because the holding force is proportional to the contact area between the two magnetically attracted halves.” These clasp together and power is thus provided to the laptop.

The connection between a MagSafe adaptor and the Mac laptop is made using two magnetic halves. This is instead of the more usual clasp/socket technique of inserting the cable inside the laptop. MagSafe on the Mac works by connecting the power socket to a Mac using magnets. The MacBook Air then gained MagSafe charging in June 2022. While still charged via USB-C, the port gained the magnets necessary to make detachment and attachment easy. Then, in 2021, Apple brought MagSafe back to the MacBook with the launch of the 14-inch and 16-inch MacBook Pro. For some time all Mac laptops were charged via their USB-C or Thunderbolt ports. MagSafe was temporarily discontinued on Macs in 2019 when Apple stopped selling the 2017 model of the MacBook Air. The presence of MagSafe on an Apple laptop was a given right up until Apple announced the 12-inch MacBook with no MagSafe adaptor in 2015, choosing instead to power it via a USB-C cable, instead of MagSafe. The MagSafe connector was loved for the fact that it softly disconnected from a Mac if the wire was yanked out, leaving the Mac safely on the desk while only the wire drops to the ground.
