On October 18, 2021, Apple announced the M1 Pro and M1 Max 14-inch and 16-inch MacBook Pro models with MagSafe 3. [15] MagSafe 3 is slimmer than its predecessor and connects to a power supply using a removable cable with a USB-C end. It supports up to 140W power delivery on the 16-inch MacBook Pro with its bundled 140W GaN power adapter which supports USB Power Delivery 3.1.

MagSafe is a series of proprietary magnetically attached power connectors developed by Apple Inc. for Mac laptops. MagSafe was introduced on 10 January 2006, in conjunction with the MacBook Pro, the first Intel-based Mac laptop, at the Macworld Expo. The connector is held in place magnetically so that if it is tugged (for example, by someone tripping over the cable), it will be pulled out of the port without damaging the connector or the port, and without pulling the computer off its surface. [1] A thinner and wider version, called MagSafe 2, was introduced in 2012. It was discontinued across Apple's product lines between 2016 and 2019 and replaced with USB-C. MagSafe returned to Mac laptops with the introduction of updated MacBook Pro models with MagSafe 3 in 2021. The earliest laptops from Apple were all under the MacBook name, which disappeared in 2010 until Apple resurrected the name with the 12-inch MacBook.

So, which charger do I need for my MacBook?

The central pin is used for communication between the computer and the power adapter following the 1-Wire protocol. The computer makes use of this to retrieve information about the power adapter and to change the color of the LEDs on the power adapter's connector. The Apple MagSafe power adapter's 1-Wire communication chip is located inside the MagSafe connector itself; the cable does not carry the data line to the power adapter enclosure.
