The MagSafe plug of your MacBook has a small light. Its colour tells you how charging is going: amber, green, flashing or completely off. This article explains what each colour means, for MagSafe 1, 2 and 3, and what to do when the light does something you do not expect.
Blue Apple repairs MacBooks in Amsterdam, including charging ports and charging problems. A MagSafe light that misbehaves is often the first sign that something is wrong with the plug, the cable or the port.
Which MacBooks have MagSafe?
- MagSafe 3: MacBook Air from the M2 and 14 and 16-inch MacBook Pro from 2021. The cable is separate from the power brick (USB-C to MagSafe 3).
- MagSafe 1 and 2: MacBooks up to about 2015. The cable is fixed to the charger.
- Other MacBooks charge over USB-C and have no light.
What do the colours mean?
- Amber: the MacBook is charging.
- Green: the battery is full, or charging is paused because the Mac is protecting the battery.
- Fast amber flashing (MagSafe 3): there is a charging problem. Disconnect the plug, wait a few seconds and connect it again.
- No light: no power is getting through, or the plug is not making good contact.
Green while the battery is not full
That is usually Optimised Battery Charging: the Mac holds the battery around 80 percent for a while to protect it. The battery menu then shows something like "Charging on hold". Also see MacBook says "Not charging".
The light flashes or stays off
- Clean the plug and the port. MagSafe is magnetic and attracts small metal particles and dust. Look into the port with a light and carefully remove dirt with a dry, soft toothbrush or a wooden toothpick. Never use anything metal.
- Try another wall socket and, for MagSafe 3, another USB-C charger and cable.
- Check the cable for kinks and fraying at the plug. See your MacBook charger cable is broken.
- Charge over USB-C. MacBooks with MagSafe 3 can also charge through a USB-C port. If that works, the problem is the MagSafe cable or the MagSafe port.
- Restart the Mac. On Intel Macs with MagSafe 1 or 2 an SMC reset can help.
The cable lets go too easily
MagSafe is designed to come loose when someone pulls the cable. If it comes loose with every small movement, check the port and plug for dirt, because a bit of dust or a metal particle stops the magnet from seating properly. A worn plug can also hold less well.
Discoloured or burnt pins
If you see black, discoloured or sunken pins on the plug or in the port, stop using it. That points to overheating from poor contact. A plug or port in that state can get more damaged or hot.
When it is the MacBook itself
If your MacBook does not charge with any cable or charger, not even over USB-C, the problem may be in the MacBook: the charging chip on the logic board, the MagSafe port or the battery. Also read MacBook not charging.

Frequently asked questions
Can I charge my MacBook with a USB-C charger if it has MagSafe?
Yes, MacBooks with MagSafe 3 also charge over USB-C.
Why does my MagSafe plug get warm?
A little warm is normal while charging. Hot, or with discolouration, is a sign of poor contact.
Does a MagSafe 2 charger work on a MagSafe 3 MacBook?
No, the plugs do not fit. Use a USB-C charger or a MagSafe 3 cable.
