macOS Big Sur 11.2.1 is officially released and fixed some MBP can’t charge issue

A week ago, macOS Big Sur 11.2 was officially launched, but today Apple suddenly launched macOS Big Sur 11.2.1. According to the update instructions, this update solves the problem that may cause the battery of some 2016 and 2017 MacBook Pro models to be unable to charge.

On the same day, Apple announced the launch of a free battery replacement program for MacBook Pro 2016/2017 that has encountered a battery failure to charge more than 1% . It is estimated that macOS Big Sur may be one of the causes of the problem, and the new version of macOS Big Sur 11.2.1 has been corrected.

One of the key points of macOS Big Sur 11.2.x is to fix the related problem of Bluetooth instability and improve the reliability of Bluetooth. The next major update, Big Sur 11.3, has entered the Beta stage, optimizing iOS Apps to run on M1, supporting PS5 DualSense /Xbox Series XS controllers and making improvements to the reminder App.
