Mac notebooks: Using and maintaining your Apple MagSafe Adapter

Use the information in this article to allow optimal usage and to reduce wear of the Apple MagSafe Adapter included with your Mac notebook computer.

To ensure maximum compatibility, use only the power adapter that came with your Mac notebook, or an Apple-authorized power adapter that is compatible with your product.

Connecting the MagSafe Power Adapter to power
Make sure the AC plug or AC power cord is fully inserted into the power adapter before plugging the adapter into a power outlet. Additionally, be sure to plug your adapter into the wall before connecting it to your computer. 

Temperature and using the MagSafe Power Adapter
The power adapter may become very warm during normal use as it dissipates operational heat through the adapter casing. The MagSafe and MagSafe 2 Power Adapters comply with the user-accessible surface temperature limits defined by the International Standard for Safety of Information Technology Equipment (IC 60950-1). To reduce the possibility of overheating the power adapter or of heat-related injuries, do one of the following: 

  • Plug the MagSafe Power Adapter directly into a power outlet or surge proctor using the AC Plug, making sure there is airflow around the adapter.

  • If you’re using the AC power cord, place the MagSafe Power Adapter on a desk, table, or on the floor in a well-ventilated location. Avoid thick carpet, bedding, or furniture that would impact airflow on the adapter as those items may trap heat radiated from the adapter case. Similarly, avoid prolonged contact between yourself and the adapter brick when the adapter is in use.

Note: The Magsafe connector on your Magsafe Power Adapter may vary based on your computer. Additionally the AC cord and AC plug style may vary based on your country.

Removing the MagSafe Power Adapter from power
You should disconnect the MagSafe Power Adapter and disconnect any other cables if any of the following conditions exists:

The MagSafe power port
The MagSafe power port on your computer contains a magnet that can erase data on a credit card, iPod, or other device. To preserve your data, do not place these or other magnetically sensitive material or devices within 1 inch (25 mm) of this port.

Disconnecting the MagSafe Connector from your computer
Disconnecting the MagSafe adapter from the computer in the manner described in the table below will reduce wear on the adapter cable and will increase the life of your MagSafe Adapter.

"T" Style MagSafe 2 Adapters

1. Grab the MagSafe 2 head.                                           

2. Tilt the connector up, down, left, or right to disengage the connection.


"L" Style MagSafe Adapters

1. Grab the MagSafe head.                                            

2. Tilt the connector away from the computer to disengage the connection.




"T" Style MagSafe Adapters

1. Grab the MagSafe head.                                           

2. Tilt the connector up, down, left, or right to disengage the connection.


Note: Do not pull on the cable itself or bend the cable to disconnect the MagSafe adapter as that will put additional stress on the cable.


Using the MagSafe to MagSafe 2 converter

If you have a Mac notebook with a MagSafe 2 power port, you will need the MagSafe to MagSafe 2 converter (shown below) to use previous MagSafe adapters or Apple Displays with the "T" or "L" style MagSafe connectors.

The MagSafe to MagSafe 2 converter connects in between the MagSafe "T" or "L" connection and the MagSafe 2 port on the computer. It can be disconnected just like the MagSafe "T" style adapter or MagSafe 2 "T" style adapter discussed earlier in this article.
