Apple has determined that “a very small number” of people have experienced an issue with the battery in their Mac notebook not charging past the one percent mark.
The issue is limited to the 13 or 15-inch MacBook Pro models manufactured in 2016 and 2017. Apple’s released emergency updates to prevent this from happening to other 2016-2017 units.
“Please update to macOS Big Sur 11.2.1 or later or install the macOS Catalina 10.15.7 supplemental update,” the Cupertino company advises in a new support document.
macOS Big Sur 11.2.1 also fixes a significant security vulnerability.
