Oct 24, 2016 Apple’s switch to USB-C means its beloved MagSafe connector probably won’t feature on its next-generation MacBooks, but that doesn’t mean it will die out completely. One reliable analyst claims Apple could introduce a “MagSafe-life” USB-C adapter with the new MacBook Pro.aaa.

Nov 25, 2019 Speaking from experience, MagSafe was a beloved feature for Mac users because accidents happen, and knowing your laptop wasn't going to go crashing to the ground if you bumped into the power cable provided plenty of comforts.

MagSafe is a series of proprietarymagnetically attached power connectors, originally introduced by Apple Inc. on January 10, 2006, in conjunction with the MacBook Pro at the Macworld Expo in San Francisco, California, United States. The connector is held in place magnetically so that if it is tugged — for example, by someone tripping over the cord — it will pull out of the socket without damaging the connector or the computer power socket, and without pulling the computer off the surface on which it is located.^[1] Despite its popularity with many users, it was discontinued across all Apple product lines between 2016 and 2019 and replaced with USB-C.

History[edit]

Usb To Magsafe Macbook Charger

The basic concept of MagSafe is derived from the magnetic power connectors that are part of many deep fryers and Japanese countertop cooking appliances since the early 2000s in order to avoid spilling their dangerously hot contents.^[2]^[3]^[4] Apple was granted US Patent No. 7311526 on MagSafe ('Magnetic connector for electronic device', issued in 2007) as MagSafe was deemed to be a sufficient improvement due to the connector being symmetrical and reversible, and the fact that magnets within a connector are arranged in opposing polarities for improved coupling strength.

Apple phased out MagSafe with the release of the Retina MacBook and 2016 MacBook Pro that replaced it with USB-C for charging and data sync.^[5]^[6] The last product with MagSafe, the 2017 MacBook Air, was discontinued on July 9, 2019.^[7]

Features[edit]

MagSafe has connector pins that are designed so the rectangular connector can be inserted in either orientation (however, the L-shaped version of the connector can only be fitted in one orientation without blocking neighboring ports, such as USB). LEDs on both the top and bottom of the connector show green if the computer battery is fully charged and amber or red if the battery is charging. MagSafe can be found on the MacBook, MacBook Pro and MacBook Air notebook computers, as well as the Apple LED Cinema Display and Thunderbolt Display.^[8]

The MacBook and the 13-inch MacBook Pro use a 60 W MagSafe charger, whereas the 15- and 17-inch MacBook Pro use an 85 W MagSafe charger. The MacBook Air has a lower-powered 45 W version of the MagSafe adapter. The power brick is smaller, but the MagSafe connector is the same as on the 60 W and 85 W chargers. According to Apple, an adapter with a higher wattage than that originally provided may be used without problems.^[9]

Apple formerly offered a 'MagSafe Airline Adapter' for use on certain compatible airplanes. It had a DC input (instead of AC like the original MagSafe chargers) and would power the computer, but would not charge the battery.^[10]

MagSafe 2[edit]

MagSafe 2 was introduced on the MacBook Air and MacBook Pro with Retina Display at the 2012 Worldwide Developers Conference on July 11, 2012. It is incompatible with the older MagSafe connectors without an adapter, and returns to the T-shaped design that points straight out, rather than the L-shape that runs along the side of the machine. The connector was made thinner and wider to fit the thinner laptops.^[11]

Pinout[edit]

The MagSafe connector pins allow for the adapter to be inserted in either orientation. The first and second pins on each side of the tiny central pin have continuity with their mirror pins.

The inner large pins are V+ (14.5 / 16.5 / 18.5 / 20 V DC). Measuring with no load will give 6.86 V DC for MagSafe and about 3 V DC for MagSafe 2; the full voltage is provided after a ~40 kOhm load is applied for one second.^[12]
The outer large pins are ground.
The tiny center pin is a data pin using the 1-Wire protocol. The computer uses this pin to change the LED’s color and retrieve the serial number and wattage of the power supply.^[12]
Only two wires – power and ground – go to the charger unit. There is no data communication via the adapter sense pin with the charger unit itself.^[12]
The maximum voltage supplied is as follows:
- 14.5 V DC for the 45 W units supplied with MacBook Air
- 16.5 V DC for the 60 W units supplied with MacBook and 13' MacBook Pro
- 18.5 V DC for the 85 W units supplied with 15' and 17' MacBook Pro
- 20 V DC for the 85 W units supplied with 15' MacBook Pro Retina

The rectangular metal shroud surrounding the pins acts as shielding for the electrical pins and a ferrous attractor for the magnet in the laptop. Creative mediasource windows 10.

Third-party products[edit]

Although Apple does not license the MagSafe connector for use in third-party products, manufacturers have devised a workaround: their MagSafe items use the actual connector from Apple's AC adapter, grafted onto their own product. Since this uses an actual Apple product, purchased legally, manufacturers believe that no licensing agreements are needed (a principle referred to as the first sale doctrine) and the patents are not violated.^[13] However, in 2010 Apple still sued one such manufacturer, Sanho Corporation for selling its very popular HyperMac battery extension products which Apple claimed violated their patents.^[14] Sanho has since ceased to sell their connector cable for the HyperMac series of external batteries.^[15]

Some fake MagSafe 2 chargers have appeared on sites such as Amazon. These chargers are often unsafe, have spelling mistakes on the charger itself, and/or have inconsistencies that the official product does not contain, e.g. the LEDs on the connector do not follow the correct colour code, or the charger is referred to as a MagSafe 1 charger rather than the second generation charger.
