Compatibility

To ensure maximum compatibility, use only the power adaptor that came with your Mac notebook, or an Apple-authorised power adaptor that's the right one for your Mac notebook.

Connecting the MagSafe Power Adaptor to power

Make sure that the AC plug or AC power lead is fully inserted into the power adaptor before plugging the adaptor into a power socket. And be sure to plug your adaptor into the wall before connecting it to your computer. 

Temperature and the MagSafe Power Adaptor

The power adaptor might become very warm during normal use. The MagSafe and MagSafe 2 Power Adaptors 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 adaptor or of heat-related injuries, do one of the following: 

  • Plug the MagSafe Power Adaptor directly into a power socket or surge protector using the AC Plug, and make sure that air can flow around the adaptor.

  

 

  • If you’re using the AC power lead, place the MagSafe Power Adaptor 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 adaptor, as those items might trap heat radiated from the adaptor case. Also avoid prolonged contact between yourself and the adaptor brick when the adaptor is in use.

 

The Magsafe connector on your Magsafe Power Adaptor might vary based on your computer, and the AC lead and AC plug style might vary based on your country or region.

Removing the MagSafe Power Adaptor from power

You should disconnect the MagSafe Power Adaptor and disconnect any other cables if any of the following conditions exists:

  • You want to clean your Apple product
  • Debris gets into the MagSafe power port (learn how to remove debris)
  • There's an issue with a pin or pins on the MagSafe connector
  • The power lead or plug becomes frayed or otherwise damaged
  • Your Mac notebook or power adaptor is exposed to rain or excessive moisture, or liquid has spilled into the case
  • Your Mac notebook or power adaptor has been dropped, the case has been damaged or you suspect that service or repair is required

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, don't 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 adaptor from the computer properly will reduce wear on the adaptor cable and will increase the life of your MagSafe Adaptor.

"T" Style MagSafe 2 Adaptors

1. Grab the MagSafe 2 head.                                           

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

"L" Style MagSafe Adaptors

1. Grab the MagSafe head.                                            

2. Tilt the connector away from the computer to disconnect.

"T" Style MagSafe Adaptors

1. Grab the MagSafe head.                                           

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

Don't pull on the cable itself or bend the cable to disconnect the MagSafe adaptor, as that puts 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'll need the MagSafe to MagSafe 2 converter to use previous MagSafe adaptors 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 adaptor or MagSafe 2 "T" style adaptor discussed earlier in this article.
