Apple has released macOS Catalina 10.15.4 along with iOS 13.4, iPadOS 13.4 and watchOS 6.2 to the public.

This update brings in several features and bug fixes which are:

1. macOS and iOS App Purchases: This update along iOS and iPadOS 13.4 will enable universal purchases for apps on iOS or iPadOS and macOS. This means that if you purchase an app on the App Store on your iPhone or iPad, you can download the same app if available on your Mac without any additional cost.  Note that the app should be available on both the platforms for this to work.

2. Music: The Music App on this version of macOS has support for time-synced lyrics for Apple Music Subscribers, just like we have on iOS 13.

3. iCloud Folder Sharing: Apple has brought support for iCloud Folder Sharing for macOS too. This is directly implemented into Finder.  Apple also introduced this feature on iOS 13.4 and iPadOS 13.4. Update your iPhone, iPad, and Mac to use this feature.

4. Screen Time: You will be able to set communication limits for your children and control who your children can contact during certain hours or during downtime.
