Following last week’s cluster of updates for iOS, iPadOS, watchOS, and tvOS, today Apple rolled out an update to macOS Catalina that adds – among other features and fixes – a new Battery Health Management tool on the Energy Saver pane of System Preferences.
When enabled, the Battery Health Management tool automatically reduces the peak capacity of a MacBook battery to prolong its life. The dialog also displays battery condition and recommends battery servicing if required. While Battery Health Management is enabled by default once the 10.15.5 update is installed, it can be disabled by the user.
Another feature of the update is the FaceTime Prominence Preference that was introduced in the other updates last week. This preference gives users the option to control automatic prominence on Group FaceTime calls so video tiles do not change size when a participant speaks.
The third big feature is Calibration Fine-Tuning for the Pro Display XDR. For those who are using Apple’s pricy Pro Display XDR, the update “adds controls to fine-tune the built-in calibration of your Pro Display XDR by adjusting the white point and luminance for a precise match to your own display calibration target.”
Other bug fixes and improvements include:
- Fixes an issue that may prevent Reminders from sending notifications for recurring reminders
- Addresses an issue that may prevent password entry on the login screen
- Fixes an issue where System Preferences would continue to show a notification badge even after installing an update
- Resolves an issue where the built-in camera may not be detected when trying to use it after using a video conferencing app
- Addresses an issue for Mac computers with the Apple T2 Security Chip where internal speakers may not appear as a sound output device in Sound preferences
- Fixes a stability issue with uploading and downloading media files from iCloud Photo Library while your Mac is asleep
- Resolves a stability issue when transferring large amounts of data to RAID volumes
- Fixes an issue where the Reduce Motion Accessibility preference did not reduce the speed of animations in a FaceTime group call
The update size depends on the Mac being updated but seems to average about 3.8GB. On a 16-inch MacBook Pro (late 2019), the update took about ten minutes to complete. As with all updates, a restart (actually several!) is required.
