One week after pushing macOS 11.2 to the public, Apple has released 11.2.1. Spotted by Apple Insider, the update includes a single change, but it’s an important one if you own an older MacBook Pro. Some people with 2016 and 2017 models recently found that a bug prevented them from charging their computer’s battery. Apple says the patch resolves that issue. You can download the update manually by opening the System Preferences pane on your Mac and navigating to the Software Update section. It will also automatically install if you have that option enabled.

Apple: macOS Big Sur 11.2.1

macOS Big Sur 11.2.1 addresses an issue that may prevent the battery from charging in some 2016 and 2017 MacBook Pro models.

Some features may not be available for all regions, or on all Apple devices.

Update (2/10): Apple has also initiated a replacement program for affected devices, so if your laptop still won’t charge beyond one percent, contact the company to get a battery replacement.
