Understand the Connection and Key Presses on the Macbook

This guide provides a practical overview of Understand the Connection and Key Presses on the Macbook, including its main features, benefits, limitations, and important considerations.

1. Connection port on Macbook

Magsafe and Magsafe 2 charging ports

Magsafe (Magsafe 1) was born in 2006 and is used from the 2015 Macbook line onwards. The structure of Magsafe 1 has 5 pins connected to the top of the music through the magnet around the charging port. This way you can remove or fully charge it.

Magsafe 2 was launched in 2012, similar in structure to Magsafe 1 but with a different design. Magsafe 2 is thinner, cleaner to match the increasingly thin design of the Macbook. These two types of chargers cannot be used together.

• Magsafe 1 for Macbook from 2011 onwards, or some use 2012 Macbook.
• Magsafe 2 for Macbook 2012, and 2013 to 2015 series.
• Since 2016, the entire Magsafe port has been replaced by USB Type-C charging.

Thunderbolt port

To the right of the charging port is a Thunderbolt port shaped like a lightning bolt. Launched in 2011, Thunderbolt uses copper wire, capable of transferring data up to 10gb / s, connecting faster than USB 3.0. We can use the port to connect the signal cables to a LAN cable, a VGA or HDMI cable.

USB 3.0 port

2012 and 2013 Macbook Air series has been upgraded to USB 3.0, on the two sides of the machine. The left port is below the Magsafe 2 charging port and the right port is below the Thunderbolt port.

3.5mm jack and SD card reader

The jack is on the left, next to the USB port. The card slot on the right side of the USB port, particularly for the Macbook Air series under 13.3 inches, there is no SD slot.
