The basic concept of MagSafe refers to the magnetic part that has been used in Japanese fryers and cookers since the early 10s to stabilize them, avoid spills of their hot contents, and avoid the high risks involved. In the case of Apple, they are power connectors that are magnetically connected to the charging port, and Apple first provided them on January 2006, 2007 with the first generation of the MacBook Pro at the Macworld Expo in San Francisco, California, and obtained a patent on it, and it was released in XNUMX .
The connector is installed magnetically in place in any direction, it is reversible, and you can pull the wire or tighten it either with intent or without “such as being stuck in the wire,” it detaches from the socket easily without damaging the wire or the port in the computer as well as avoiding dropping it. Despite its popularity with many users, it was discontinued between 2016 and 2019 and replaced with USB-C.
Apple phased out MagSafe with a Retina MacBook and 2016 MacBook Pro that was replaced by USB-C. The last MagSafe product was discontinued with the 2017 MacBook Air, on July 9, 2019. On October 13, 2020, Apple announced the return of a new version of MagSafe to the iPhone 12 series.

MagSafe has a socket with a magnetized frame in a rectangular shape that is affixed to the charging port in any direction, it was originally a T-shape and of course the cable was directed outwards in the opposite of the device, and later it became an L-shape, with the cable being routed along the side of the computer either forward or back . The LED lights at the top and bottom of the connector are green if the computer battery is fully charged, and amber or red if the battery is being charged. MagSafe technology was present on MacBook, MacBook Pro and MacBook Air laptops, as well as Apple LED Cinema Display and Thunderbolt screen.
Every 13-inch MacBook and MacBook Pro was using the 60W MagSafe Charger, while the 15 and 17-inch MacBook Pro used the 85W MagSafe Charger. The MacBook Air includes a 45-power adapter also with the same charger. This means that it works with both 60W and 85W chargers, and according to Apple, a charger with a higher wattage than the original can be used without problems.
MagSafe 2
MagSafe 2 was introduced on MacBook Air and MacBook Pro at the Worldwide Developers Conference on July 11, 2012. Made thinner to fit into thinner laptops, and also wider to maintain magnetic grip strength; It is not compatible with older MagSafe connectors without an adapter. It also goes back to the T-shaped design that points directly out, instead of the L-shape that runs along the side of the device, Apple might have done this to not block the other ports on either side.
Problems with MagSafe
Several users, as of October 30, 2011, reported problems with charger socket wires, disconnected charging socket, damaged adapters, and loss of some charging socket connection points.
Several methods have been devised to protect MagSafe from damage, including wrapping the cable with protective tape or plastic film around the wire.
In 2008, Apple posted an official response acknowledging that there were problems with the MagSafe adapters that some called “MagUnsafe,” which included an incomplete circuit connection and the disconnection of the wire from the magnetic terminal of the charger. Once recognized, a class-action lawsuit was filed on May 1, 2009, alleging that the MagSafe power adapter contained rapidly perishable wires and a noticeable rise in temperature and this could cause fires.
Apple released an operating system update in October 2010 that it claims resolves the heat issue. However, this update did not work on some older MacBooks. However, Apple continued to sell the older MagSafe as of 2017.
MagSafe technology is back with a new look
with Announcing the iPhone 12, Apple announced a wireless charger with MagSafe technology as a new EcoSystem accessory. MagSafe makes it easy to charge your iPhone wirelessly, which is undoubtedly a big step forward, as it is different from the past. It's a fully wireless charging standard, and paves the way for a future iPhone without ports. This means better water resistance and more space inside the body to be used for other technical things, such as an increase in the size of the battery or the development of new technology.
Wireless charging functionality and MagSafe accessories are available on iPhone 12, 12 mini, 12 Pro, and 12 Pro Max.
Apple introduced wireless charging for the first time with the iPhone 8, and the latest version stopped at 7.5 watts, as for MagSafe, it doubled to 15 watts. The matter is not only about speed, but also about ease of use. Once the phone is placed on the charging mat, it will automatically set in place and start charging immediately.
