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:
