The macOS Catatina 10.15.5 update is now available with Battery Health Management, FaceTime updates and more

Apple on Tuesday released macOS Catalina 10.15.5, an update to the Mac operating system. The marquee feature of this update is Battery Health Management, which was revealed to developers back in April. This feature adjusts the MacBook's battery charging so that it doesn't reach full capacity, thereby extending the overall life of the battery. (Charging lithium-based batteries to 100 percent can cause wear and tear, which shortens battery life.)

The update also includes a new option in FaceTime to turn off the user zoom during group FaceTime conferences. Apple introduced this option in iOS when it released the iOS 13.5 update.

For users who own Apple's Pro Display XDR, macOS 10.15.5 has controls for fine-tuning the white point and luminance of the display's built-in calibration.

According to the release notes, there are the "bug fixes and other improvements" in the update (the company says this document has the details on the included security updates):
