Apple has released macOS Catalina 10.15.5 as a free update for all supported Mac users. The big new feature in the update is a tweak to how your MacBook handles a complete charge. In order to maximize the lifespan of the battery cell itself, Apple says your MacBook can now charge to 100 percent of what’s recommended to ensure your battery doesn’t degrade considerably over time. Of course, you can always turn the feature off in settings.
In addition, macOS 10.5.5 includes plenty of bug fixes and security patches.
To install the update, head over to the Settings app on your Mac and check for new software. If you’re curious, those with a MacBook that has a Thunderbolt 3 port on it will have the battery health tool enabled automatically after the upgrade finishes. Of course, all new MacBooks shipping with Thunderbolt 3 onboard will have 10.15.5 pre-installed.
