Apple Releases macOS Catalina 10.15.4 With Screen Time Communication Limits and Real-Time Apple Music Lyrics

Apple today released macOS Catalina 10.15.4, the fourth update to the macOS Catalina operating system that was released in October. macOS Catalina 10.15.4 comes a couple of months after the release of macOS Catalina 10.15.3.

macOS Catalina 10.15.4 can be downloaded from the Mac App Store for free using the Update feature in the System Preferences app.

The macOS Catalina 10.15.4 update introduces Screen Time Communication Limits, a feature that was first brought to the iPhone in the iOS 13.3 update. Communication Limits allow parents to put limits on who children can contact through FaceTime, Phone, Messages, and iCloud Contacts.

There's a new Head Pointer Accessibility option that allows the mouse cursor to be controlled with head movements using the Mac's camera, plus real-time lyrics are included for Apple Music. Real-time lyrics allow lyrics for a song to scroll by in real-time to the music so you can follow along with what's being sung. Apple has also added iCloud Folder Sharing, which can be done from Finder.

Though not directly related to ‌macOS Catalina‌ 10.15.4, Apple is adding a new universal purchase option for macOS and iOS apps, which will allow Apple device users to purchase one app that works across multiple platforms. These features will be available following the release of macOS Catalina 10.15.4 and iOS 13.4. Release notes for the update are below:

This update also includes bug fixes and other improvements.

- CalDav migration support when upgrading to iCloud reminders on a secondary device

- Fixes an issue in Safari where a CAPTCHA tile may display incorrectly
- Resolves an issue where Reminders may send notifications for completed reminders
- Fixes an issue with screen brightness for the LG UltraFine 5K display after waking from sleep

With so many people working from home, TAKE CAUTION WITH BEING AN EARLY ADOPTER with this update. Clone your system with Carbon Copy Cloner (CCC) before installing.

Half a planet working from home so able to download immediately and lots of surprised people blaming Apple for not handling the load. I'm impressed they released it given the present situation - think I might wait a while before installing given the limited support options!

Waiting to see if the eGPU issues are solved...o_O
No, same problems!
4 Months now ...
I‘m finished with Apple after 20 years.
I upgraded my old Mac Pro 2010 to a Mac mini 2018 with an eGPU from Razor (X).
With Mojave all was fine.
Since Catalina the Music App lost thousands of covers, eGPU won‘t run smooth ....

Every single problem reported, nothing is getting better.
This is crap Apple!
