Macs everywhere can now upgrade to macOS Catalina 10.15.4. This adds iCloud Drive folder sharing as well as Apple Music time-synced lyrics and other enhancements.

Collaborate with iCloud Drive folder sharing

iCloud file sharing was already part of macOS, allowing multiple people to work with a single document stored on Apple’s cloud-storage service. Today’s operating system update expands that to entire folders.

Apple today posted a how-to on iCloud Drive folder sharing for Mac.

This feature also just debuted in iPadOS 13.4 and the iPhone equivalent.

Have fun with the Apple Music’s time-synced lyrics

Mac users can enjoy the Apple Music time-synced lyrics, which gives users scrolling, karaoke-style song lyrics. The feature lets users follow what’s being sung in real-time as the songs play.

This feature debuted in iOS 13 last autumn. Now Apple is bringing it to macOS users as well.

Screen Time Communications Limits too

Screen Time helps parents control how much time their children spend on their devices. macOS Catalina 10.15.4 adds additional options. “Communication Limits let you control who your children can communicate with and who can communicate with them throughout the day and during downtime,” explained Apple.

During the day, parents can limit a child to communicating with FaceTime and Messages only with people in the Contacts app. At night, the child can be restricted to talking with people on a shorter list, like only their parents.

This is another feature that came first to iOS and is now expanding to Mac.
