With your MacBook information in hand, navigate to the appropriate section below to see the kind of Mac charger you need. Apple chargers for a MacBook 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. In the first-generation connector, the inner large pins are V+ (14.5 / 16.5 / 18.5 / 20 V DC). Measuring with no load will give 6.86V DC for MagSafe and about 3 V DC for MagSafe 2; the full voltage is provided after a ~40 kilohm (kΩ) load is applied for one second. [18]
