Apple today seeded the third beta of an upcoming macOS Catalina 10.15.5 update to developers for testing purposes, two weeks after seeding the second beta and over a month after releasing macOS Catalina 10.15.4 with Screen Time Communication Limits, iCloud Folder Sharing, and real-time Apple Music lyrics.

The new macOS Catalina beta can be downloaded from the Software Update mechanism in System Preferences after installing the proper software from the Developer Center.

macOS Catalina 10.15.5 introduces a new Battery Health Management feature for Mac notebooks, which is designed to extend the overall lifespan of a Mac's battery by reducing the rate of chemical aging.

The Battery Health Management feature analyzes the battery health of a laptop and its charging pattern, and in some cases, will preserve battery longevity and health by not charging a MacBook to its full capacity, which can reduce battery life.

When a Mac is used plugged in and the battery is largely kept full, Battery Health Management will kick in and will stop short of a full charge. The feature can be enabled and disabled in the Energy Saver section of the System Preferences app.

Looking forward to the release of 10.15.5 since everything in Catalina will be super stable by then, right? ??

I'll be happy if it just fixes the intermittent kernel panics in 10.15.4.

I really hope this update resolves some of my software issues on my 16 inch macbook.
1) it shuts down when in sleep mode often
2) graphics switching glitches
3) internet connectivity issues, it's connected but the internet itself is not working properly.
4) ghosting/jittery scrolling

I'm upset since these problems arose after updating to 10.15.4 from 10.15.3.
