Apple released a new firmware for the MagSafe charger, according to MacRumors. The firmware is designed to work with iPhone 12 and newer and AirPods Pro 2.
The new firmware version is 10M1821, which is higher than the previous 10M229 firmware. Note that in the Settings app, users will see a different version number than the firmware number, with the update appearing as version 255.0.0.0 (the previous firmware was 247.0.0.0).
The MagSafe charger was released with the iPhone 12 model in 2020, and this is the third firmware update Apple has provided.
Apple has not provided firmware update instructions for the MagSafe charger. Given the recent release of the iPhone 14 model and AirPods Pro 2, the firmware may be optimized for these devices.
In addition, there is no clear way to update the MagSafe charger firmware, but it will need to be plugged in and connected to an Apple device to initiate the firmware update.
