Air mag safe cable not lighting up or charging

Hey peterfromwellesley,

We have a couple of articles we'd like to share on charging with you to see if either of these help resolve the issue with your MacBook Air not charging.

Charge the MacBook Air battery - Apple Support - Found in this article is the following:

Customize battery settings.  You can set different options for your battery in System Settings.

• Optimized Battery Charging: This feature helps to reduce the wear on your battery and improve its lifespan by learning your daily charging routine. It delays charging the battery past 80% when it predicts that you’ll be plugged in for an extended period of time, and aims to charge the battery before you unplug. In System Settings, click Battery in the sidebar, click  by Battery Health, then turn on Optimized Battery Charging.

If your Mac battery status is “Not Charging” - Apple Support - Offers the following suggestions:

The Battery Status menu on your Mac laptop might say “Not Charging,” even if it’s connected to power. This can happen for a few reasons:

• Your computer temporarily paused charging to extend the life of your battery. Your battery may drain to 93% or lower before it begins charging again. Depending on the model of your Mac, you may be able to turn off battery health features in Battery settings. See If your Mac battery won’t charge completely.

• Your computer is connected to a power source that gives it enough power to run, but not enough power to charge the battery. For example, your Mac might not charge when it’s connected to a low wattage adapter. You can still use your Mac without draining its battery, but the battery won’t charge, even if you turn off your Mac or put it to sleep.

• Your computer is running at a very high performance level that uses more power than the power source provides. For example, some apps—such as video editing software and video games—can require more power and drain the battery more quickly.

If your Mac won’t charge at all, see If your Mac battery won’t charge.

After reviewing and trying the steps suggested, if your new MacBook Air still isn't charging we recommend reaching out to Apple Support.

Good luck!
